NOVATECH CHOOSES OPTOCORE TO OPTIMISE SWITCH TO AES
Munich, 04th March, 2014
Having regularly used Optocore products for events requiring custom audio distribution,
Australian premier rental staging company, Novatech Creative Event Technology, has now
The company first adopted Optocore systems back in 2012. According to Project Manager
(Audio), James Sacca, “At the time we were looking for a solution that would transport
multiple channels of audio as sends and returns. Due to the nature of the particular event,
we also needed something that could be quickly cabled after a series of road closures. The
multimode fibre made this an easy task. We were more than happy with the reliability and
performance that Optocore products offered and our system design engineers have
continued to utilise Optocore products ever since.”
Stereosonic Music Festival, where the system made its debut.
Most recently they have purchased a series of X6R-FX converters, equipped with AES I/O,
to move up from analogue to digital signal transmission. “We had been researching options
on how best to utilise the AES inputs on our L-Acoustics rig by doing something that other
companies weren’t. We pride ourselves on being able to offer the highest quality solution
and running a standard AES cable from FOH to feed our LA8’s didn’t feel like the best way to
do it,” Sacca continued. “We also wanted to couple the move to AES with our recent
purchase of an L-Acoustics K2 System to offer our clients the absolute best in audio quality.”
After extensive research and demos Optocore was chosen for its stability and flexibility.
Novatech, who operate a busy schedule of event support throughout the country,
had first discovered Optocore at Frankfurt Prolight+Sound which Sacca and
company owner / technical director, Milenko Novakovic attended with a specific agenda.
“AES signal transport was at the top of the list and after discussions with the Optocore team
we were impressed with what the X6R-FX product offered.” Their belief was rubber stamped
by another major Australian Optocore customer, Norwest. “We initially approached them for
a loan of their X6R-FX units so we could carry out some testing, and they were more than
happy to assist,” reports the Novatech man.

“We were already aware of the capabilities and flexibility of the units, and so our focus with
the loan system was seeing how it would act as an AES returns core and ensure that it
catered for an adequate set of redundancy options.” And as a result, they placed the order.
The new set-up is configured as 16 x AES inputs housed in FOH drive racks. Fibre is run to
stage left and right where another X6R-FX at each point is configured as 16 x AES outputs.
Sacca added that some customisation boosted the system even further. “We were happy
with all the functionality except for when the fibre connection was lost. The LA8’s would not
revert to analogue fall back mode because they were still receiving an AES stream from the
Optocore system — this resulted in the audio being completely cut.
“With the help of L-Acoustics, the Optocore team was able to design a custom firmware
version which rectified the issue. This means that we can run analogue and AES
simultaneously with the system automatically switching over if the fibre connection is lost.
In addition Optocore provided in-depth technical training to all of the company’s senior audio
technicians,which was extremely well received.
The new system made its debut at the Stereosonic Music Festival and has since been
deployed on numerous concerts, festivals and events.
Summing up, James Sacca says, “The implementation process of this system was a lengthy
one — but the support we received from Optocore in delivering our custom firmware design
was a critical — not only in the decision to purchase the system but also in the integration of
the Optocore solution across our existing infrastructure and extensive product range.
“Since commissioning our new system design in late 2013 it has been a game changer when
it comes to handling long distance audio and DMX cable runs. There hasn’t been a touring
engineer who hasn’t complimented us on the quality of the audio in our concert systems,
post the switch to AES.”
OPTOCORE/BROAMAN DEVICES AT HEART OF NEW CORONATION STREET SET
Advanced site-wide routing system is based on ‘automatic homing’
Munich, 12th Feb, 2014
The relocation of the famous ITV Coronation Street Street lot, from Manchester’s Quay
Street Studios to the 7.7 acre studio and production facility on the Trafford side of
MediaCityUK, has brought with it a significant streamlining of signal flexibility, with
BroaMan and Optocore fibre distribution devices playing a major role in the new
Set of Coronation Street, ITV, Coronation Street/MediaCityUK
Set in a fictional town in the north of England, what has become the world's longest-
running television soap opera is a British ‘institution’, having first been broadcast back in
A unique, fully integrated transport solution was conceived by the show’s Technical
Manager, Stan Robinson, in conjunction with project engineers Phil Cooper and Nigel
Fowler from system integrators TSL. The design was based on meeting all Coronation
Street workflow and system requirements.
The show's Technical manager Stan Robinson, ITV, Coronation Street/MediaCityUK
Earlier, AVC Electronics, who had worked on the previous Coronation Street HD upgrade
at the old studios, had been appointed broadcast consultants for the project, and their
lead consultant Raz Khan had carried out technical evaluation and system configuration
of all equipment to meet these requirements. Installation, testing and commissioning was
then undertaken by TSL, the successful bidders, after the Optocore and BroaMan
solution had been adopted.
"Street of devices"(left:Optocore/BroaMan) ITV, Coronation Street/MediaCityUK
“The broad design was based on the previous set-up in Quay Street with the intention of
streamlining, and improving wherever possible,” stated Cooper. “This was carried out
using a combination of contemporary technology solutions and TSL’s industry
experience, along with the vision of Stan Robinson.” Robinson had wanted an advanced system
that could transport all audio, video and data
signals site wide over fibre, from any of the studios or lot. He had been introduced to
Optocore by Dan Muchmore of Clear-Com while investigating talkback systems, and
invited them to demo their optical transportation system in the presence of Jim Crothers
the MD of AVC.

“I needed a solution that was not too taxing for the operational crew — little more than
plug and play — and I also wanted a box that when connected by fibre and all the level
signals would be there,” continued Robinson.
“The ultimate aim was to come up with a system that increased efficiency, cut rigging
time to a minimum and was sufficiently resilient to avoid production downtime; and
irrespective of where the box was plugged in on set, the system would be intelligent
enough to recognise it.
“Also with fibre we knew there would be no cable length limitations. Since HD-SDI would
only travel 50m over the copper cable we had at Quay Street here we could transport
HD-SDI from the central apparatus to the furthest point via optical fibre. ”
With active support from the German fibre specialists’ Application Engineer, Maciek
Janiszewski, Optocore loaned test equipment to establish proof of concept, with AVC
Electronics installing a point to point system in Quay Street to provide single channel
floor feeds. “We tested for audio and latency and everything was fine,” reports Robinson.
"Expert on air", Control Room, ITV, Coronation Street/MediaCityUK.
Thus the BroaMan and Optocore architecture forms the beating heart
of the new broadcast network which has been constructed around ten BroaMan Route66
interfaces and two WDM frames. These combine to create one centralised router, feeding
the ForA 96 x 128 matrix distribution unit, and forming part of the identification, CWDM
and control to the Optocore router.
Instead of having Optocore sockets dotted around the site TSL also noted that by using
hybrid camera fibre cables they could have every Optocore point active through the site
— simply by patching into the SMPTE 311M network. Robinson explains, “This gives us
additional resilience. There are 100 camera points supplying two patch systems — one
in the main building and one out on the lot, enabling patching to either Camera Base
Stations or the Optocore Router.
“Each gallery has its own stagebox, and we simply wheel it to where we are shooting
and plug in to our camera cable network. In effect, the whole site becomes our studio
Phil Cooper explains how TSL had implemented the system. “We knew
that the ‘automatic homing’ of the Optocore system — whereby stageboxes will find their
home gallery from any live connection point — would be a valuable benefit.
“However,” he added, “the main USP of this Optocore system is the ability to plug a
stagebox in anywhere and be connected automatically to the correct gallery or OB van.
Upon connection, the system discovers where the portable stagebox is connected and
the central Video Router directs the assigned channels to the correct location.”
In addition to video, ITV can also route data and audio automatically since the
stageboxes are a multi-faculty resource, which make connectivity available on set,
whether in the studios, out on the lot or on location. This includes: Audio sources (boom
mics) and monitoring returns; SDI monitoring and sources (from portable cameras or
recorder playback); 4wire talkback circuits for boom operators and assistant directors;
Router control panels to control SDI monitoring.
There are five production control areas – comprising galleries and OB vans, each with a
corresponding stagebox, incorporating Optocore DD2FR-FX and BroaMan Repeat48
rack devices. Having specified a Studer Vista 1 and D21m I/O interface in the two main
galleries TSL deployed ten Optocore DD2FR-FX devices to transport native MADI over
the fibre network.
The path is configured from the 15 connection points available from the Optocore
system, with distribution to the portable stageboxes via the same SMPTE fibre
infrastructure as the camera. Each gallery or van has a corresponding stagebox which
can be connected to the core routing system (via a wallbox) or taken on location and
connected (point to point) to a van – again, using standard camera floor cables.
Wherever the mobile stagebox is connected, the router will recognise the location and
automatically patch the signal between stagebox and control room. “The key benefit of
this stagebox system is reduction of set-up times,” acknowledges Cooper, and this is
critical given the arduous production schedules. “With the exception of the cameras, all
other crew equipment can be connected with local cables to a stagebox; so by plugging
in one fibre cable they can start using it.”
This elegant solution is a far cry from the traditional routine of connecting many long
individual cables to the nearest studio wallbox and then patching every mic signal, audio
return, talkback, video and control signal to the relevant gallery or van.
Production on the new Coronation Street set got underway in early January. “We were
given a short lead time of just one week of rehearsals at the new site, so everything had
to work first time and be operationally easy to use,” concludes Stan Robinson. “We are
delighted with BroaMan and Optocore solution, which has offered us an incredibly
OPTOCORE KEEPS NITRO CIRCUS FLYING HIGH FOR CAPITAL SOUND
Munich, 4th Dec, 2013
After selling out shows across Europe last year, Travis Pastrana's Nitro Circus Live is
back on tour — beginning at the brand new 40,000 capacity Tele2 Arena in
Nitro crew setting the ramps @Tele2 Arena in
Capital Sound provided the sonic backdrop, including their Optocore X6R-FX
interface rack, as some of the world’s hottest and best extreme sports stars of
freestyle motocross, BMX and skate took part. The show also featured tricks and
stunts on the 15ft high Nitro ‘Gigant-A-Ramp’ where skis, tricycles, skateboards,
freezers and boogie board stunts were featured.
Paul Timmins, Capital Sound Project Manager and a great team beside him.
However, the state-of-the-art football stadium, with its retractable roof, proved to be a
challenge for the sound crew to achieve flexible pattern control and retain sightlines.
Capital project manager, Paul Timmins, fulfilled a design that was deliberately rigged
off-centre towards the corner (for the stadium shows), to optimise the impact for the
spectators. “Here we were able to provide sound reinforcement over a 270° angle,
because of the unusual way in which the seats work, whereas when we move to
arenas this will be a full 360° of audio.”
But Capital are fully aware of all the challenges embedded in this unusual event,
having worked on the European tour last year, meeting the request by long-serving
sound designer and engineer, George Gorga for an advanced 2-zone fibre
distribution solution, for both flexibility and a superior signal path.
George Gorga, "the" sound designer and engineer
The X6R-FX converter offers the highest degree of flexibility concerning the I/O
configuration. Six different card types enable customisation of the card slots on the
rear of the device; the conversion of analogue signals — 16 inputs, 16 outputs, 8
inputs and 8 outputs or dual microphone inputs with two independent adjustable
preamps — to AES/EBU is provided as well as the sample rate conversion for
This provided Capital Sound with all the flexibility they needed. “The idea is to build
the six [loudspeaker] hangs of [Meyer Sound] Milo and Mica clear of anything that’s
going on as we only have a six hour window to get it up in the air,” he explains.
Each self-powered Milo hang had been customised. “With the show being in the
base of the venue, the cable routing, power distro and any amps that might be sited
on the ground would ordinarily get in the way.
The tour uses eight hangs of PA in two areas of the building picking up local power
which is possible by using the fibre signal distribution. “We effectively break up the
distro, giving each hang its own dedicated power distribution and an Optocore
device. So we can put any hang in any position within the building, interlinked by the
Close up Capital Sound Socapex Channel & Optocore X6R-FX on top.
This approach, using Optocore, was essential to a design configured back in August.
“We looked at the conventional way of distributing the power and signal on the Meyer
self-powered system — with a left and right distro rack that would then feed the
power to all cabinets via a long, fairly heavy Socapex power cable, giving all cabinets
their own home run signal feeds. However, that cable is chunky and we wanted to
avoid that here. We also wanted to have an element of speed hence the Optocore.”
The stacks of cabinets are already pre-cabled and on dollies — and the rack on the
top has a 32 amp 3 phase in, which then distributes into the Socapex that feed 12
ways of power. An XTA DP226 and Optocore X6R deal with the input to all the
cabinets, driven by a 150m-200m long fibre that runs between each of the arrays.
“Therefore, we can split the arrays up, and if we want to hang them huge distances
apart we can do that by picking up local power in the venues.”
He explains that the Optocore X6R rack has now become the standard package for
Capital Sound’s larger events. The company first purchased eight of these interfaces
for Take That’s 2011 Progress Live tour before adding another six for deployment on
the high profile British Summertime Festival in London’s Hyde Park in July.
Both audio tech and crew chief Kevin Smith and system tech Mike Savage Nachamin
were impressed with the Optocore deployment. The former confirmed, “By having
two X6Rs at FOH for distro, and running fibre to the other X6Rs on top of each pack,
we could move the hangs around if we needed to. From those X6Rs, split into two
zones from a Lake processor, we run two audio feeds on AES into each hang, before
passing into the DP226 to act as an AES to analogue converter.”
Paul Timmins says that issues of set-up time were as important as sonic excellence.
“Both for ourselves and for George [Gorga] our goal was to achieve great audio, but
this project is also about speed, so that the actual mechanics of the show — ramps,
matting, etc — can go in and the system has been designed with that in mind.”
He believes this elegant design provides both flexibility and high visibility. enabling
the ramps to be moved around and the hangs to be extended with minimum hassle.
“Having just two cables running to each hang is a great advantage in an environment
where sightlines are paramount, and the hangs need to be trimmed high to avoid
getting in the way of the bikes.”
OPTOCORE DELIVERS QUALITY SOUND OVER LONG DISTANCES
FOR CHEONGSHIM PEACE WORLD CENTER
Fiber Transport System Boasts Superior Audio, Reliability and Cost-Effectiveness as Key Benefits
Munich, 3rd Dec, 2013
When the CheongShim Peace World Center first opened in late 2011, the AV technology team knew that
the vast size of the arena (it seats up to 25,000 people) would dictate the type of audio and data
transport system that would support it. Traditional analog lines were just not going to cut it.
Instead, the team turned to Optocore, the leading provider of scalable, high-bandwidth, low-latency
fiber-optic networks for the transmission of audio, video and data in a variety of markets, for its
fiber transport technology.
Inside CheongShim Peace World Center, Optocore Devices on the right
Located just over 21 miles outside of Seoul in the Gapyeong District in South Korea’s Kyunggi
province, CheongShim Peace World Center is owned by Unification Church (also known as
Moonism) and is the largest multipurpose hall in the area, to date. The approximately 1,367-
square-foot (127 meter) steel-frame structure boasts a 29 ½ foot (9 meter) high arena that is
generally used for various activities by the Unification Church’s general assembly, as well as for
corporate events, concerts, plays or CF (commercial) shooting.
Paired with Yamaha gear, the recently installed Optocore fiber system is just what was needed to
properly transmit audio digitally from the microphones to the Front of House (FOH) and the PA system
to its large constituency. Without it, the size of the venue would be just too big to transmit microphone
signals over analog lines.
“We chose the Optocore system for its reliable optical transmission system, in order to ensure
the audio would be heard throughout our large arena,” says Kim Hanchoon, audio/video
technical director, CheongShim Peace World Center. “Traditional cabling was just not going to
be reliable enough and while Optocore is still a rather new technology to many here in South
Korea, we were happy to expose the team to Optocore’s fiber optic transmission method and all
of the benefits that can be reaped from it.”
The equipment has been installed to support Front of House (FOH) as well as the sound control
room. The Optocore DD32E system consists of three X6P-16IN units in the stage rack, each
with 48 channels of analog mic inputs to digital and one X6-16OUT with 16 channel digital to
analog converter. In addition, the DD32E provides AES/EBU feeds to the system’s loudspeaker
DSP controllers at the main mix position, with a Yamaha PM5D mixing console loaded with one
Optocore YG2 fiber optic card and two additional Optocore YS2 Slave cards that allow for up to
48 inputs and outputs to/from the Optocore network to the mixing console, as well as control of
the X6 Optocore microphone preamps.
Close up Sound control room: Meyer Sound in harmony with Optocore
In the sound control room there is a Yamaha DM2000VCM mixing console loaded with an
Optocore YG2 fiber optic card and two Optocore YS2 Slave cards that allow for up to 48 inputs
and outputs to/from the Optocore network to the mixing console as well as control of the X6
Optocore microphone preamps. Rounding out the system, the technical team uses speakers
and a speaker control unit from Meyer Sound.
Of the many benefits that the Optocore system has provided to the church, three stand outs for
Hanchoon include sound quality, console connectivity and long-distance transmission.
“Having the Optocore system in place enables us to transmit signals by a fiber optic cable
without noise or any audio loss,” he explains. “When our audio is passing through small outputs
such as at the microphone level, there is no noise to distract our constituents; they are hearing
the sermon, loud and clear, which is something that’s very important to us. In addition, it’s easy
to control the Optocore system with the touch of a button on the console, while it also can
handle the user to patch in all 48 channels, easily configuring the control layers.”
Finally, Hanchoon says he is pleased with the long-distance capabilities that fiber optic
transmission has afforded to the church.
“It’s often the case when using a multi-cable setup for a long distance signal, that there might be
a loss of signal transmission caused by the circuit size that is over 200 meters, such as in our
case,” he says. “By utilizing Optocore and fiber optics instead, we can overcome the distance
barriers, ensuring smooth, reliable transport every time.”
“We are so pleased to provide such a complete solution to the A/V team at CheongShim World
Peace Center,” says Tine Helme, director, Optocore. “The fact that our system can be used in
three ways—as an electrical transmission system by multi-cable (analog), signal transmission of
console and stage box (using PM5D and DSP50) by UTP cable, as well as optic transmission—
is further proof of the unprecedented benefits that fiber transport can bring to even the most
challenging of situations, such as CheongShim’s large venue.”
OPTOCORE INTERCOM CONNECTIVITY TAKES OFF IN UAE
Thomsun Trading reports positive reaction at InfoComm MEA
Munich, 31st Oct, 2013
Thomsun Trading, Optocore’s Dubai-based distributors, found that their creative
presentation of the German manufacturer’s intercom devices at InfoComm MEA paid
dividends, and they received some excellent new enquiries as a result.

According to Thomsun product specialist, Alok Ghurde, the presence of two Optocore
V3RFX-INTERCOM devices allowed them to connect a remote RTS DKP 16 CLD
coloured keypanel to the ZEUS III LE+ 16-channel intercom matrix. “Due to the nature of
the display, we also managed to promote and discuss BroaMan and how it could be
used in an AV install/events venue,” reports Alok. “We received excellent feedback and
interest from system integrators as well as end-users — and this augurs well for our
plans to showcase BroaMan and Optocore in a big way at the CABSAT show early next
Close up: RTS & Optocore devices, Infocomm MEA 2013, Dubai,UAE
In fact Thomsun Trading has been receiving a good deal of interest generally from
clients in the region particularly for the Optocore range of Intercom interfaces (both
RTS/TELEX and Clear-Com). “Having taken on RTS representation recently, we
showcased the connectivity using the Optocore V3R-FX INTERCOM for RTS.
“The flawless, perfect site coverage that Optocore and BroaMan provided for the Kuwait
50th Constitution Day celebrations last year, along with other similar large Optocore
system deployments in the recent past, have been noted by local rental as well as SI
companies, and as a result, we’re seeing more specific enquiries for Optocore.”
To back this up, Alok reveals that Creative Communications Group of Qatar recently
started full-fledged operations in Abu Dhabi, UAE and added newV3R-FX INTERCOM
devices to its Optocore inventory for Clear-Com Intercom systems. “CCG has been an
Optocore user since 2009 and the company’s decision to add the V3R-FX INTERCOM
devices demonstrates the faith clients place in the reliability, flexibility and
costeffectiveness of the Optocore system.”
A further interesting development is the purchase of Optocore DD32R-FX AES/EBU
devices by the Abu Dhabi Media Company for installation in the near future.
OPTOCORE VOTED BEST NETWORK PROTOCOL AT PLASA
Munich, 16th Oct, 2013
The comparative sessions took place on the opening two days of this year’s PLASA
Show at ExCeL London, and were supervised by Roland Hemming (of RH Consulting)
as part of the new AudioLab Interactive experimental concept, which he masterminded.
An impressive number of attendees on each day were given voting buttons in order to
register their preference, as six of the most established industry audio protocols —
Optocore, MADI, Dante, EtherSound, CobraNet and Analogue — were closely
scrutinised. The Optocore solution was voted the best in terms of signal transmission
quality by different independent audiences on both days.
Names from left: Andy Cooper - Yamaha CA,
Richard Northwood - COMS, Andreas Hildebrand - ALC NetworX GmbH; Maciek Janiszewski, Optocore GmbH
The Optocore presentation was made by Support Engineer, Maciek Janiszewski, and
supported by Optocore’s UK distributors, Sound Network.
Explaining the process Roland Hemming said, “We tried to be as fair and everyone
seemed happy with the methodology.“However, it would have been unfair to play all
these protocols in 20 second bursts back to back and expect people to vote; so we put
pairs of systems up against each other — Dante against MADI and EtherSound against
CobraNet — and the winner of the first two rounds went through in a three way shoot out
with Optocore and Analogue.”
He said that while the winner of the first two rounds differed on each day, in the threeway
final shoot Optocore always won, with Analogue bringing up the rear. “It was the
only consistent result we had and it was a good result for Optocore — although no-one
believed that any of the systems weren’t good enough; it was all high quality audio.”
Presenter Maciek Janiszewski, Support Engineer, Optocore GmbH >
The playback was driven from Yamaha’s DME mix engine using high quality output
analogue cards into Yamaha Studio monitors, with typical reference tracks such as
Steely Dan used as source material. All participants provided different cards, Optocore
supplying YG2 and Y3R-TP interface I/O’s and DD4MR-FX network device (although
only the YG2’s were used for comparison purposes).
Since DME32 only has four mini YGDAI card slots two were cascaded together, while a
common wordclock was used, since DME would drive all simultaneously. However, the
individual Wordclock signals on each protocol were compared, which revealed that the
Optocore clock was extremely stable, and set itself immediately after connection.
“For Ethernet based protocols higher phase shift, longer locking as well as slight
instability could be observed,” stated Janiszewski.
The listening test was just one of a number of network tests conducted as part of six
intensive sessions at the new Interactive event, which saw 700 people attend over the
four days. The Network Shootout was by far the longest session, yet people remained
incredibly engaged, states Hemming.
“Although it was a fairly random, subjective test we are delighted to have won on both
days,” concluded Janiszewski.

FLUSHING, QUEENS, NEW YORK, SEPTEMBER, 11, 2013 — Optocore, the leading provider
of scalable, high-bandwidth, low-latency fiber-optic networks for the transmission of audio,
video, intercom and data in a variety of markets, was chosen by Audio Incorporated, who is the
supplier of sound reinforcement and communication equipment for U.S. Open Tennis, to provide
X6R-FX-INTERCOM devices for the communication system used during this year’s U.S. Open
opening ceremonies held at Arthur Ashe Stadium, part of the USTA Billie Jean King Tennis
Center in Flushing Meadows-Corona Park, Flushing, Queens, New York. The high-profile tennis
event began on August 26 and ended on September 9.

As Mike Sinclair of Audio Incorporated, the audio designer for the U.S. Open live events for the
past six years, explains, “We needed to find a way to connect the roof of the Broadcast Center
building with our central patch area at the other end of the stadium in the photographers’ pit. We
had to be ready to transport the program audio feed, Clear-Com Encore Analog Party Lines
converted to 4-wire for a production channel and a lighting channel. We also used Optocore’s
100Mb LAN tunnel between devices to network show control computers and DMX lighting
Audio Incorporated employed Optocore X6R-FX-INTERCOM devices using the fiber
infrastructure of Arthur Ashe stadium to connect and multiplex the various different audio and
data streams over one pair of fiber lines. “We had to be ready for any eventuality and the
Optocore X6R-FX-INTERCOM performed flawlessly with connectivity to spare.” Sinclair said.

“We needed to get communications and audio up to the highest reaches of the stadium, in a
hyper-crowded situation,” says Rom Rosenblum, events communication system technician, U.S.
Open, and applications engineer, Clear-Com. “CBS, ESPN and every broadcaster covering the
event was already hooked into existing copper lines. Without the Optocore devices, we’d have
been communicating with cell phones to run the Arthur Ashe Kid’s Day event and Opening
Ceremonies. Instead, as soon as we got the facility to install a piece of glass up to the roof, we
were in business. A plug-and-play solution was never more welcome!”
Rosenblum also cites Optocore system’s comprehensive front panel level meters and status
indicators as invaluable as well. Known to be a favorite feature among audio engineers, this
combination allows instant visual verification and provides an immense troubleshooting aid for
cabling problems. Additionally, he says the LAN feature made it easy for the team to access
their network anywhere in the system.
The X6R-FX-INTERCOM has 8 intercom duplex channels including data. The device can also
be used as eight line inputs plus eight line outputs, plus 4 serial I/O or 2 GPIO.
“Optocore’s fiber systems are known for their top-notch features, immense reliability and dual
redundant fiber runs and power supplies/sources,” says Mike Sinclair, owner, Audio Incorporated.
“By utilizing Optocore, rather than copper cables, we were able to save time and
effort for all of our communication needs during the U.S. Open.”
CAPITAL SOUND EXTENDS ITS OPTOCORE NETWORK FOR HYDE PARK
BRITISH SUMMER TIME FESTIVAL
Munich, July, 12th, 2013
When the Rolling Stones arrived at London’s Hyde Park on July 6 to perform the first of
two concerts at the AEG-Barclaycard British Summer Time 10-day season, they were
safe in the knowledge that their glorious oeuvre of classic rock favourites would reach
the 65,000 or so fans situated in proximity of any of the ten delay towers courtesy of an
Optocore redundant fibre distribution system.
Hyde Park, BST, British Summer Time, London, UK
Capital Sound had been awarded the sound reinforcement contract by promoters AEG
Live/Loud Sound — Royal Parks’ new tenant — and the London-based production
company deployed the Optocore system that they purchased in 2011 for the Take That
Progress Live stadium tour — supplemented by a further six newly-acquired XR6-FX
Capital Sound technical manager, Ian Colville, said he had no hesitation in specifying
this solution to set up the transmission ring covering around 1km of the site. “Optocore
was the only transport system that would allow us to create a complete redundant loop
over this distance with no hums and buzzes,” he said.
“Nothing on copper comes close
— and in any case you can't suddenly extend the network by another 200 metres if you
realise you need it, as you can with fibre. This solution gives us complete isolation.”
Toby Donovan, Capital Sound, Sound Engineer
with Optocore Rack
Colville knew that by adding a further six X6R-FX-8AE/8MI converters to the eight
already in their inventory they could connect to 11 locations as well as dual redundant
units at FOH (plus back-up). Configured with 8-channel AES3 I/O 8-channel Microphone
Inputs and Wordclock I/O this provides the capability of 32-channel AES-EBU output.

The redundant units at the FOH tower connect to these remote locations — including
nine delay towers, VIP stand and second FOH tower (for lighting control) via the fibre
network, carried on catenaries and delivering AES-EBU audio feeds. Connectivity to the
Martin Audio PA’s MLA VU Net control network, running the dedicated Merlin
management system, was via an Ethernet tunnel — with RS485 data connection to the
XTA DP-226 processor ports located in the VIP stand and at the FOH tower.
The network topology was in place by the time AEG-Barclaycard British Summer Time
opened up with Bon Jovi on July 5th.
Ian Colville had first taken the decision to adopt an Optocore platform two years ago to
feed Take That’s stadium ‘ring’ system (a series of roof-mounted delay clusters instead
of traditional delay towers). With the sightline issue taken care of, pristine signal
transmission over distances up to 200 metres had been required.
“Experiments to try and transmit this across huge distances via AES over copper or RS-
485 showed signal degradation and instability, which would have been unacceptable.
The answer was an optical fibre solution and everyone we spoke to pointed towards
In conclusion, he said, “Optocore is an absolutely fantastic system — very intuitive and
easy to use and reconfigure.”
HOLGER SCHWARK PATCHES PET SHOP BOYS WITH OPTOCORE NETWORK
Munich, June, 26th, 2013
Mixing the Pet Shop Boys’ current Electric world tour, the band’s long term sound
engineers, Holger Schwark (front-of-house), and Seamus Fenton (monitors) have been
relying on an Optocore ‘multicore’ system to transfer signals, and keep the sound within
the digital domain.
Holger has been carrying two Optocore DD4ME MADI converters in his compact FOH
side rack for some time, with a third DD4ME at the monitor desk. Providing production
on this tour is Capital Sound Hire — who themselves invested in an Optocore system for
last year’s Take That stadium shows.
Holger Schwark, sound engineer at FOH
Both Holger and Seamus have chosen the compact DiGiCo SD10-24 consoles, along
with a DiGiCo SD-Rack at the monitor desk. While these consoles come equipped with
an optical loop interface, they decided instead to run Optocore as an entirely
independent network, giving them greater flexibility to patch signals between their
‘playback world’, the SD-Rack, the two mixing desks, a MADI-equipped Mac Mini at
FOH, FX units at FOH, and finally an independent additional MADI output for occasional
multichannel recording — keeping everything digital.
The process began on a previous tour in 2009, when their DiGiCo SD8 consoles did not
have optical connections. “Since we use MADI-enabled multichannel playback
equipment on stage, I did not want to rely on copper connections so I was looking for a
reliable, redundant fibre system that would also guarantee that the digital clocks on
stage and FOH stayed in perfect sync at all times,” said Holger. “Once we started using
Optocore DD4ME's, it quickly became obvious how much extra flexibility it gave us in
patching communication mics across, or sending FOH special effects back to monitors,
without needing an XLR return core," he said.
Seamus Fenton, sound engineer at monitor place
Meanwhile, down in Monitor World, Seamus Fenton has been running two fibres out of
his Optocore linked to FOH, which is effectively merging two MADI streams. The DiGiCo
SD-Rack, which provides inputs for mics (as well as live keyboards), is connected to the
monitor console via BNC MADI cables, with full control over gains etc. from the monitor
desk. A second MADI output on the SD-Rack feeds one of the DD4ME inputs, to be
picked up by FOH and the recording output. "We decided early on that gain control from
FOH is not required, as we only have a few mics anyway and rarely change their gains.”
The multitrack playback, that contains an essential part of Pet Shop Boys' music,
originates in a redundant pair of MADI-equipped computers near the monitor desk,
combined using a DirectOut EXBOX.BLDS switchover unit, which feeds the other
DD4ME input on stage.
The first output of that DD4ME goes into the monitor desk, carrying the multitrack
playback and also comms mics and some effects from FOH, while the second output is
reserved for recording.
The DD4ME was designed to offer digital I/O compatibility with a range of devices, such
as digital consoles with coaxial BNC MADI I/O’s, and the huge amount of channels
exchanged by a single DD4ME makes it a highly cost effective interface, with two MADI
input and two MADI output ports allowing the transmission of up to 128 input and 128
output digital audio channels per device.
At the FOH end of the two fibre cables, fitted with standard expanded beam connectors,
the two DD4ME devices have a total of four MADI I/O's — two connected to the MADI
ports of the FOH desk, offering a theoretical maximum of 112 channels each way
between the console and the Optocore network. The third DD4ME MADI I/O is taken by
a Mac Mini with DiGiCo’s UB MADI interface, featuring tasks like system alignment tools,
analysers, live plugin processing and recording for virtual sound checks, while the final
MADI I/O connects to a TC6000 reverb, with a DirectOut EXBOX.AES converter in line.
“Optocore is our entire backbone,” says Schwark. “It allows me to patch everything
through the network.
I connect both of the consoles’ ports to the network, as well as my
peripherals, and can now use the desk's built-in tricks for virtual soundchecks for, say, 40
recorded channels, while still connecting to my reverb engines and analyser software on
the higher-numbered channels. It works beautifully well and makes best use of the
existing I/O on the back of the desk, without adding a bulky local I/O rack.
“From the first day, what I loved about this system is its reliability, and the fact that it has
'Link 1' and 'Link 2' LED’s for the fibre connections, so I can see if communication with
the stage end is established.
This means that we don't have to do extensive line checks
anymore — great in festival situations where we don't use our own cables, but use
festival-provided DiGiCo-style fibres. Plug it in, wait until the other end has plugged in by
occasionally checking the Link LED's, check if the shout mic works … line check done!"
Seamus Fenton also has nothing but praise for the Optocore system. “It is a
phenomenally flexible tool,” he says, “it just always works!”
Playing through the new Nexo STM PA, which Capital Sound Hire recently invested in,
at London’s O2 Arena the sound engineers (and experienced system tech Al Woods)
ensured a dynamic set delivery from this synth-driven ‘80’s band, leading up the finale
that included old hits such as Always On My Mind and West End Girls.
OPTOCORE SOLUTION ENSURES SAFE SIGNAL TRANSMISSION AT ORANGE WARSAW FESTIVAL
Munich, June, 26th, 2013
Optocore was utilized heavily at the recent Orange Warsaw Festival in Poland, which
was headlined by Beyoncé.
Held at the National Stadium (Stadion Narodowy) since 2008 the event’s growth has
been such that for the last three years the Festival has been broadcast by TVN.
The Optocore equipment used by turnkey festival service specialists, PogoArt and
provided by distributors, M.Ostrowski Sp.j, was principally used for recording
purposes, and for providing a mix for web streaming.
Orange Warsaw Festival 2013, Poland
“The biggest challenge,” states Optocore support engineer Maciek Janiszewski, “was
the distance from the stage to the recording truck — which was around 300m. Also
there were issues regarding the connectivity on stage — as there was no information
provided by the bands on what sort of signal was being delivered for recording.”
Countdown backstage, Orange Warsaw Festival, Poland
Two parallel systems were in operation: the first was a Yamaha CL5 with Rio Series
interfaces, providing analogue connectivity on stage; the second was an Optocore
set-up, with DD4ME digital I/O, with two MADI input and two MADI output ports, and
DD32R-FX digital interface (for AES-EBU) connected to Yamaha AD8HR 8-channel
remote microphone preamp/AD converters on stage. In addition, an Optocore
DD2FR-FX interface was connected via MADI to a Yamaha DM2000 console,
providing a digital split and another 64 channels available for recording.
Part of the Optocore set up at Orange Warsaw Festival, Poland
The Optocore system was preconfigured with two macros, so that the sound
engineer could easily, with a single click, select which signals from the stage would
be output on both MADI and DD2FR-FX. The first macro recalled the routing of 64
MADI channels from DD4ME on stage to both DD2FR-FX MADI output ports, while
the second macro recalled repatching both DD2FR-FX MADI outputs to analogue
inputs from stage. As a result one click in the software changed the entire
configuration and changed the source for all outputs between analogue (DD32R-FX
with AD8HRs) and digital (DD4ME) input signals.
“Designing the Optocore system in such a way ensured not only clean signal
distribution over the vast distance from stage to truck but also the flexibility and
simplicity required in relaying the appropriate MADI signals for recording purposes,”
The Festival itself was once again a huge success, with the 58,000 capacity stadium
rocking not only to the music of Beyoncé, but also other headliners including Fatboy
Slim, Tinie Tempah, Basement Jaxx and Cypress Hill.
NEW OPTOCORE SYSTEM FOR DÜSSELDORF SCHAUSPIELHAUS
Munich, June, 14th, 2013
Custom firmware allows connection to fire alarm system
With more than 100 years of tradition behind it, the Düsseldorf Schauspielhaus is among
the largest and most important theatres operating in the German speaking countries.
Since 1970 it has been located in the Bernhard Peacock building at Gustaf-Gründgens
space where it was spectacularly designed by architect Bernhard Pfau. The sculptural
structure boasts curvaceous lines, is staggered in height, is divided into a large house
(with 760 seats) and a small house with up to 200 seats.
It also contains the ‘Young
Schauspielhaus Dusseldorf-Rath’, with separate 300 and 100 seat theatre spaces.
Designed “to respond to the challenges of a globalized world” at the same time it hosts
local artists and institutions as well as other art forms including dance, experimental
music and the visual arts.
To keep up to date with modern technical requirements the theatre recently upgraded its
network distribution by installing an Optocore fibre digital backbone. In order to meet
safety requirements and conform to legislation, the house system is now interfaced to
the fire alarm/voice evacuation system via one of the modified Optocore X6R-FX units.
Optocore dealer, Synthax, provided a number of modules to installation contractor,
Salzbrenner Stagetec Media Group enabling them to provide a fully redundant
distribution system from stage to FOH.
Auditorium, Duesseldorf Theatre, Germany
Salzbrenner’s rack design revolved around two central Optocore DD32R-FX AES-EBU
hubs from which the network is constructed, and includes a number of Optocore/SANE
converters connected to the Yamaha mixing platforms. These include X6R-FX providing
16LI (Line In) channels and V3R-TP-8LI. In addition six X6R-FX are equipped with 8MI
(Mic In)/8LO (Line Out) boards, with four V3R-TP-8LO, X6R-FX-16MI, X6R-TP-8MI/8LO
The new technology has provided more flexible routing options for sound engineer,
Hans-Jürgen Becker and the Schauspielhaus technical team.
Said Synthax Optocore product specialist, Kai Reiter, who supported the installation,
“Optocore are well known for their flexibility and customised solutions. This time, in
addition to the state-of-the-art high channel count platform, they delivered the unique fire
alarm firmware, which allows the fire alarm to trigger the Optocore system mute. Thanks
to this feature the Playhouse passed all the rigorous safety tests and conforms to fire
OPTOCORE'S NEW INTERCOM INTERFACES MAKE U.S. DEBUT AT INFOCOMM 2013
Munich, June, 13th, 2013
Used with IC44 Boards, Generic X6R-FX and V3R-FX Enable Reduced Channel Needs
Optocore, the leading provider of scalable, high-bandwidth,
low-latency fiber-optic networks for the transmission of audio, video and data in a variety of
markets, including pro AV, live and fixed installations and broadcast, is demoing its new generic
X6R-FX-INTERCOM-IC44 and V3R-FX-INTERCOM-IC444 interfaces at the Clear-Com booth
(921) during InfoComm 2013. The new interfaces are the latest in Optocore’s portfolio of
intercom solutions designed specifically for Clear-Com, RTS and AES3-based intercoms.
The X6R-FX-INTERCOM-IC444 has eight line inputs, eight line outputs, eight GPI and eight
GPO with relay and auxiliary power outputs for external circuits. The V3R-FX-INTERCOMIC444
features four line inputs, four line outputs, four GPI and four GPO with relay and auxiliary
power outputs for external circuits. The line’s name derives from the IC444 board, which is
equipped with two 37-pole connectors, one male, the other female, and provides four line
inputs, four line outputs and four GPIO. The X6R-FX can be equipped with two IC444 boards,
and the V3R-FX with a single IC444 board.
Optocore developed the audio-based intercom interfaces after fulfilling a custom order for the
Norwegian state broadcaster, NRK, with similar systems. For that order, Optocore worked with
sister company BroaMan to populate the 4LI/4LO board with four GPIOs to enable bidirectional
communication, while incorporating 3G/HD/SD-SDI connectivity in order to allow camera signals
to be routed via a single fiber connection to an OB van. This signal can then be uplinked back to
the broadcast center, with the monitor picture transmitted to the speaker in the opposite
“These new intercom solutions provide users with a highly cost-effective option for permanent
installation and live broadcast applications,” said Tine Helmle, director, Optocore. “The addition
of the GPI/GPO connections adds even more value to the product, enabling the user to achieve
a higher level of communication.”
OPTOCORE APPOINTS OLTBERT ITS EXCLUSIVE DISTRIBUTOR IN RUSSIA
Munich, May 16th, 2013
Optocore, a leading choice for powering professional
audio, video and data transmission networks in a variety of markets, including broadcast, post
production and AV, is proud to announce that it has named Oltbert, Ltd. its exclusive
distributor in Russia. The two companies have been working together since 2012. Moving
forward, Oltbert will oversee all sales, service and support of Optocore’s technology in Russia,
further strengthening Optocore’s worldwide reputation.
“Optocore’s audio transport systems are smart, cost-effective solutions offering a very good
extension of intercom systems, one of our main focuses,” says Alexander Trukhanov, Head of
the Broadcast Department, Oltbert. “We came to know the team at Optocore through its
relationship with Clear-Com, a major U.S.-based intercom manufacturer that we also represent
here in Russia.”
Oltbert will stock all Optocore system components, including BroaMan’s full range of network
solutions. Oltbert has been representing Clear-Com in Russia since 2003 and has a long history
of developing the business of foreign companies for the Russian market. Some of Oltbert’s highprofile
customers include TTC Ostankino, The Bolshoy Theatre, Channel 1 and NTV, all based
in Moscow, as well as the Mariinskiy Theatre in Saint-Petersburg, among others.
"We are very excited to be working with Oltbert and are looking forward to a successful and
prosperous relationship,” says Tine Helmle, director, Optocore. “The Russian market has
always been a high priority for Optocore and Broaman, as we already have quite a few
applications in Russian theaters and stadiums to date. Having such a well-known and reliable
partner such as Oltbert will certainly help us to further increase the awareness of both brands in
SOUND.COM and Optocore mastermind opening of IPL
Munich, May 6th, 2013
Since 2010, SOUND.COM has been at the forefront of some of the biggest sporting
and entertainment events in India.
Therefore, when the company embarked, at the beginning of the new financial year
with the Opening Ceremonies for Indian Premier League, the world-leading Twenty20
cricket championship, they were confident they could put on an audio spectacle to
match similar ceremonies, starting with the Commonwealth Games 2010, The
National Games in Ranchi and the Oman Tattoo in Muscat.
Salt Lake Stadium in Kolkata, India, before Opening
The multi-purpose Salt Lake Stadium in Kolkata was chosen to host the opening
ceremony of the cricketing franchise this year with the inauguration promising to be
one of the most spectacular events ever witnessed. Built in 1984, the stadium is the
largest in India and the second largest in the world with a capacity of 120,000. With
its astroturf surface the facility primarily caters to football matches and has also
hosted athletic events in the past.
But according to SOUND.COM MD, Warren Dsouza, it isn’t an easy venue in which
to design and deploy an audio system. “It takes a lot of experience, and one has to
work through a lot of infrastructure related obstacles in order to put a system
With bases in Mumbai and Delhi, SOUND.COM sent a proposal to main contractors,
Dutch based Poly Worldwide Entertainment setting out their credentials. “The belief
that they had chosen the right audio company in India was established as soon as
we opened our flight cases,” he said. “We had had everyone inspecting and admiring
our Optocore digital transport system and our self-styled OptoRacks,” he said.
The latter combined a large number of Optocore devices with Dolby Lake processing,
and the Optocore network was wired in a redundant ring for fibre failure back-up.
Additionally there was an analogue back-up to each amplifier position.
“This technology has allowed SOUND.COM to scale to any level of audio production,
no matter how big the stage is. But nothing takes away from the human element —
and the ability to integrate all this is the ultimate key to a successful show,” said
The successful cooperation between SOUND.COM sound engineer Sunil Karanjikar
and co engineer, Poly Worldwide’s Fred den Dulk, with their respective teams, had
been the underlying reason for a successful show, he said.
A large JBL VerTec PA system was rigged, driven by Crown ITech-HD 12000 and
LabGruppen PLM10000Q amplifiers, with every loudspeaker element networked and
controlled using the Lake controller and Harman’s Performance Manager.
Sound.Com deployed four OptoRacks, each consisting of 1 x DD32R-FX and 1 X6R-
FX (16 Mic In) units. One each was positioned at the console, stage left, stage right
and at a central delay position for the delay arc. Also available were Optocore
DD32R-FX, DD4MR-FX, DD2FR-FX MADI interfaces, although on this occasion the
event was not multitracked.
Sound.com & Optocore devices in harmony
Finally, the racks also housed a network switch that ran via a spare fibre link in the
cabling, to help provide network control over the Dolby Lake devices. Stated Sunii
Karanjikar, “Optical isolation allowed us to run the various positions on different gen-
sets without having to worry about power induced issues.”However, the stadium would get extremely hot and humid — as high as 38°C — and
so all devices had to be continually monitored for overheating.
And here Optocore came to the rescue, as Sunil Karanjikar explained. “Though the
network switches developed a communication error because of the heat, the
Optocore devices performed flawlessly and we were able to use the System Ethernet
option on the Optocores to regain control of the Lake devices which we had lost.”
For headline act Pitbull, the touring engineers had specified Avid consoles and
SOUND.COM supplied the entire kit and backline gear for the act as well.
consoles were patched into the PA and monitors using Dolby Lake devices and the
input matrix feature on the devices helped to match multiple consoles.
Summing up, Warren Dsouza said, “The main challenges were really logistics —
weather, rigging, getting the gear into the stadium with West Bengal waybill
bureaucracy. Actually the business of putting the kit together and executing the show
was a breeze.”
And Sunil Karanjikar added, “As for the Optocore, the visiting engineer specifically
commented as to how the network seemed a lot faster using this system than on a
dedicated IT network switch.”
OPTOCORE SUCCEED AT PROLIGHT+SOUND 2013
Munich, April 22nd, 2013
The Optocore team celebrated the 20th anniversary of its groundbreaking
technology at this year’s Frankfurt Prolight+Sound (and ten years since the
founding of the company in Munich).
A large contingency from the international trade media joined in the celebrations
on the opening day, enjoying traditional Bavarian apfelkuchen and champagne,
while in an address, founder Marc Brunke presented some of the company
highlights over the years.

The following day Optocore entertained around 40 of their key customers, OEM
partners and resellers at a special business lunch where the main item on the
menu was Bavarian weisswurst (white sausage).
Said Tine Helmle, “We couldn't have asked for a more appropriate location to
celebrate this milestone. Many thanks to all the trade press and customers who
helped make the occasion so memorable.”
OPTOCORE LAUNCH GENERIC INTERCOM INTERFACES
Munich, April 19th, 2013
Optocore, a world leader in fibre optic network solutions, has expanded its series
of intercom interfaces — following the development of proprietary intercom
systems for various OEM partners.
The new generic X6R-FX-INTERCOM-IC444 and V3R-FX-INTERCOM-IC444
interfaces will make their world debut at this month’s Prolight+Sound Show in
Frankfurt (April 10-13).
The nomenclature is derived from the IC444 board, which is equipped with two
37-pole connectors — one male, the other female — and provides 4 Line Inputs,
4 Line Outputs and 4 GPIO. The X6R-FX can be equipped with two IC444
boards while the V3R-FX can be equipped with a single IC444 board.
These latest solutions are the result of fulfilling a custom request from Norwegian
state broadcaster, NRK. On that occasion Optocore’s sister company, BroaMan,
populated the 4LI/4LO board with four GPIO’s to enable bidirectional
communication — but provided SDI enhancement, to allow camera signals to be
routed via a single fibre connection to an OB vehicle and be uplinked to the
broadcast centre (with monitor picture transmitted to the speaker in the opposite
“This version of the Intercom device with the reduced channel count (4/4) is a
highly cost effective option for permanent installation and broadcast applications.
Additionally it offers the GPI/ GPO connections, which adds further value to the
new product,” says Tine Helmle, Director of Sales and Marketing.
Due to the success of this, Optocore have now produced the two audio-based
The main features of the X6R-FX-INTERCOM-IC444 are: 8 Line Inputs; 8 Line
Outputs; 8 GPI; 8 GPO with relay; auxiliary power outputs for external circuits
The main features of the V3R-FX-INTERCOM-IC444.are: 4 Line Inputs; 4 Line
Outputs; 4 GPI; 4 GPO with relay; auxiliary power outputs for external circuits.
Both products are now shipping, and are available ex-stock.
OPTOCORE: 20 YEARS OF PIONEERING HISTORY
Munich, April 15th, 2013
April 2013, Munich, Germany … Optocore GmbH was founded in 2003 to
manufacture and distribute the Optocore fibre optic digital network system created,
trademarked and patented in the early ‘90s, and supply a range of devices to
But the Optocore story really begins more than a decade before that.
In 1991, Optocore founder Marc Brunke was a teenager playing saxophone in a
band. “We were onstage somewhere, and the sound system had a very bad snake,
with noise, hum, and all sorts of problems,” Brunke recalls. “I thought that
professionals would be using fibre optics for their snakes and did some research to
find one. But I discovered that, in fact, no one at all was making them — so I started
to build one.”
Marc Brunke, President & Founder of Optocore GmbH
Still at school, the following year he entered the design he had created into the
Bundesjugend Forscht, a German science competition for students. Receiving more
than 10,000 entries a year in seven subject areas, it is the largest competition of its
type in Europe.
Brunke won, which garnered him meetings with then Chancellor Helmut Kohl and
other government dignitaries.
As a result, in 1993 Brunke began to develop his optical network system in earnest.
This marked the birth of the Optocore system — celebrating its 20th birthday this year
— as it became the world’s first fibre optic network system designed explicitly for
transmitting real-time digital media.
Optocore achieves lift-off
By 1996, Brunke was ready to unleash his vision on the world, and the first Optocore
modules were shown at the Frankfurt Musik Messe/Prolight+Sound expo. A digital
fibre optic network system was radical way back then, and this was the first year any
network designed for digital audio had been shown. While the Optocore system was
more powerful and technologically advanced than the Ethernet-based systems that
were appearing at the same time, there is often resistance to change, and fibre
optics was a less familiar technology to the audio community. And so educating the
market became one of Brunke’s top priorities.
By the time three years had elapsed, the market was steadily responding to Marc
Brunke’s innovations and demand for Optocore products was increasing. The dotcom
wave was peaking at that time, and developers were in high demand. Brunke
Electronic, as the company was still known, was growing.
The first optocore devices in 1996
Around the same time, Marc Brunke met Rüdiger Bormann, who would become
Optocore’s head of analogue R&D. Bormann was then working for loudspeaker
manufacturer Opal Audio Vertrieb GmbH, and saw potential for synergy between the
two companies. Brunke agreed and the two companies combined forces. The first
fruit of the collaboration came quickly, with the launch of the first LX4 devices (stage
and FOH ADA boxes for live sound) in 2000.
The outcome was the reliable, fibre optic snake that Marc Brunke had first set out to
build seven years earlier.
Permanent installation like stadiums, theatres, opera houses and congress centres
are the key markets for Optocore. Increasingly, theatres and opera venues around
the world began turning to Optocore networks to meet their needs, sensing that the
Optocore system not only satisfied their current requirements, but provided a growth
path to the future. The Parma Theatre in Italy, the Cirque Royal / Koninklijk Circus in
Brussels (Belgium), the Mozarteum in Salzburg (Austria), the Bastille Opera in Paris
(France) and the America Gardens Theatre at Epcot in Orlando (USA) were just
some of the permanent installations that took place during the early part of the
Sports stadiums nowadays double as event locations and sophisticated sound and
network systems are expected for spectacular shows. Two of the most outstanding
stadiums featuring Optocore networks are the Olympic Stadium in Berlin, which has
been relying on Optocore since 2004, and the GM Place in Vancouver, which started
working with a complex Optocore network in 2008.
In the five years since, major Optocore solutions have been provided in large scale
venues throughout the world. Some of these include Opera Bastille and Opera de
Lille (France); Emirates Palace, Abu Dhabi and Royal Opera House Muscat, Oman
(Middle East); Swedish Theatre, Helsinki, Stockholm Concert House and Aarhus
Theater, (Scandinavia); Metrapark Arena, Montana, Banff Centre, Canada, Luxor
Hotel, Las Vegas and Fantasyland Theater, Los Angles (North America); Cheong
Sim World Peace Center, Seoul, and Tokyu Theatre Orb, Japan (Far East) and High
School for Musik Karlsruhe and Düsseldorfer Schauspielerhaus (Germany).
Besides the permanent installation market, broadcast was always one of the key
markets for Optocore devices. One of the first radio stations equipped with Optocore
was Polskie Radio, Warsaw in 1996. With the ability to transport numerous audio
channels, video and data safely over extremely long distances, with redundancy (and
virtually no latency) Optocore started to find a home in OB vans all over the world —
for instance the NBC in New York (Saturday night show), BBC TV and Radio OB
trucks in the UK, the CBC Radio OB van in Canada and more recently Mediaset,
Products: Olympic rings meet Optocore rings
The dawning of the new millennium found the digital revolution finally taking hold in
audio production outside of the recording studio and permanent installations, bringing
with it the need to move multiple channels of digital audio into and out of Optocore
The first response to this requirement came with the release of the DD32 in 2002,
which allowed 32 AES/EBU streams to be interfaced with the Optocore system.
With the ability to move many channels between the Optocore system and either the
analogue domain or the predominant digital audio format, the system quickly came
into its own and the world started to take notice … so much notice, in fact, that
Optocore GmbH was finally founded in 2003.
The new company lost no time in its development programme, adding interfaces for
getting signals in and out of the Optocore network, and releasing the X6-series 16
channel analogue-AES/EBU converter units. These can be fully integrated into the
Optocore network by the DD32E and serve as converter units in stand-alone
The incorporation of Optocore happened not a moment too soon, as 2004 proved to
be a big year for the firm. While business generally boomed, the clear highlight was
the use of the Optocore system to carry the audio for the opening and closing
ceremonies of the 2004 Summer Olympic Games in Athens.
For the Olympic Stadium, packed with 72,000 spectators, more than 40 Optocore
devices, connected by more than four kilometres of fibre, in two separate redundant
rings, carried the audio for the spectacular opening pageant, as well as for the
parade of dignitaries and host of Greek musicians that graced the Closing
Scaling Olympic heights
The successful use of Optocore technology for the Athens Olympics brought an
unprecedented amount of attention to the system, and made 2005 the year in which
it became the ‘must have’ technology for massive events, including New Years Eve
in Times Square, the U.S. Presidential Inauguration ceremony, New Orleans Jazz
and Heritage Festival and the Pope’s World Youth Day in Cologne. Many events
made use of the new DD32E, which, for the first time, added the ability to
synchronise an OPTOCORE network to an external word clock.
Over the next two years, Optocore maintained its brisk pace, releasing five new
products and supporting an increasing number of prestigious events and installations
New Year’s Eve 2008 heralded a banner year for Optocore, with the foundation of
the audio system used in the renowned Times Square celebration. As the year
progressed, Optocore continued to supply signature events, while cementing its role
as an open network platform (with transport of open standards such as AES/EBU,
MADI, DMX or MIDI in full size), establishing technical partnerships with industryleading
digital console manufacturers such as Studer, Soundcraft, Neumann and
Digidesign to augment its existing relationships with Yamaha and DiGiCo. The 2008
release of the DD2FE Optical MADI interface added seamless interfacing with Studer
and Soundcraft consoles.
In August, Optocore was once again called on to serve as the backbone for the audio
system at the Opening and Closing Ceremonies of the Beijing Summer Olympics at
the Bird’s Nest Stadium. And barely a month later, Optocore North America, Inc. was
set up in Toronto, Canada.
It seemed that the company would find it difficult to top such a year — yet it managed
to do so in the first month of 2009, when the Optocore system was selected for use
during the historic inauguration of U.S. President, Barack Obama. In fact the
company has kept up these traditions, supplying huge fibre infrastructures for the
Opening and Closing Ceremonies at the London Olympics last year and two major
networks for President Barack Obama’s second presidential inauguration on January
Other recent developments for Optocore have been setting up of several successful
OEM partnerships. First they enabled Clear-Com, the global giant in voice
communications systems, to offer digital fibre and SANE CAT5 networks for real-time
data, network, word clock and audio signal distribution. Then they produced similar
versions of their V3R-INTERCOM-FX and X6R-INTERCOM-FX devices for RTSTelex
before partnering with Duran Audio to produce a digital audio interface for the
Dutch company’s Intellivox range of AXYS® products.
It took the world 15 years to catch up with Marc Brunke’s vision of a reliable, highquality,
versatile, cost-effective network for audio, video, and data. But the Optocore
system, having been proven time and again to be all of those things, is now the
professional’s choice for critical applications.
In the past few years, Optocore has continued to go from strength to strength,
pursuing a path of extending partnerships with other manufacturers, developing a
much greater eco-policy with the development of the more efficient ‘R’ series and
taken a much more dynamic approach to providing MADI interfaces. It has also
played a major role at the London Olympics Opening and Closing ceremonies …
while still finding time to set up a dedicated sister company, BroaMan, whose
products are aimed primarily at broadcasters and any applications requiring
customised SD/HD/3G video transport or routing solutions.

OPTOCORE TAKES X GAMES TO THE EXTREME
GB4D simplifies the network distribution high in the French Alps
Munich, April 9th, 2013
X Games, the annual event, controlled and arranged by the U.S. sports broadcaster
ESPN, focuses on action sports.
Inaugurated in 1995 as two seasonal events, for the fourth year the Winter X Games
moved outside the US to the skiing and snowboarding haven of Tignes in the French
Alps recently, where more than 125 athletes from all over the globe competed. In
addition to X Games Tignes, 2013 is also the first year that the event has gone truly
global, with other events taking place in Aspen (USA), Foz De Iguaçu (Brazil), Barcelona
(Spain), Munich (Germany) and Los Angeles (USA).
Superpipe, X Games, Tignes, France
Brought in to assist with the sophisticated audio signal distribution was experienced
rental company, Gilles Bouvard Events and Entertainment (GB4D) — who are specialists
at big event productions of this nature (working in extreme conditions). Bouvard has long
been an advocate of Optocore’s optical fibre network solutions, and once again a large
deployment of the German company’s interfaces ensured successful signal flow within a
Bouvard confirmed, “The audio vendor for the X Games was my former associate, Julien
Terrier with his new company A+ Events. I suggested to him that Optocore be used to
provide all the fibre network signal distribution.”
The event in France was co-produced by Canal+ Events on behalf of ESPN, and GB4D
provided virtually all the audio equipment for the competition zones, to assist A+ Events.
This included the control tower audio boards and FOH equipment, the fibre network, the
PA, cabling and some of the freelance technicians. They also provided the event video
Superpipe, X Games, Tignes, France
The audio transmission was based around two Optocore loops — one ring for the Super
Pipe competition area, with five X6R-FX network converters for the main PA and one for
the VIP area, and a second for the Slope Style competition area, with two X6R-FX
interfaces. The master control room was equipped with two DD2FR-FX (offering MADI
ports), two DD32R-FX (AES-EBU) and an X6R-FX — and the entire Optocore system
was controlled from a single desktop PC.
For signal transport, since the distances between nodes were long, GB4D used mainly
300m Neutrik XTREME fibres for all links. The primary ring measured a distance of
2.1km and the secondary 600m (constructed around 12 nodes, plus spares).
L’Acoustics LA8 and Lab Gruppen PLM10000Q amplifiers fed the main PA hangs and
the Super Pipe’s deck fills were remote controlled via Optocore’s LAN.
Inputs included background music, live DJ, wireless announcer microphones, various
media and advertisement sources and TV truck feeds. “For the announcers, the wireless
links were greatly simplified thanks to the Optocore network, and the ease of feeding
signals into the system from various nodes,” confirmed Gilles. “As for the outputs, the
Optocore fibre network allowed a simple routing of the various signals feeding the
amplifiers all around the site, and the possibilities offered by macros allowed a simplified
routing and ease of modification for all the various live and recording feeds.”
GB4D designed a redundant FOH position, deploying two Midas digital desks, fully

Gilles Bouvard compared the challenge of working high in the Alps, with the opposite
climatic extreme — since GB4D recently deployed a vast Optocore and BroaMan
network over a huge distance for Kuwait’s 50th Constitution Day celebration.
“In fact there is little difference,” he said. “On the one hand we have the high
temperatures and sand storms, on the other the very low temperatures and snow. We
find ourselves in two similar extreme situations and we have to find reliable solutions.
“I think that working in those difficult environments helps us develop a real technical
expertise. We have learned to adapt technically to those constraints, for example with
the PA and cabling, but more essentially for the monitoring of the systems, which is
crucial in this type of event and in these conditions. The use of an Optocore network
simplifies this enormously.”
With X Games in particular, as the event develops globally, so the technical challenges
increase exponentially, as the time frames reduce. “Reliability is fundamental,” continues
Bouvard. “All the vendors present here are snow and mountain specialists, so we are
ready for the challenges of these technical constraints.”
Summarising the project he had nothing but praise for the role played by Optocore. “The
ease of the Optocore implementation was a major step forward for this project. The most
notable aspects were the simplification of the routing system and increased reliability of
the wiring on site, the total redundancy and a real-time monitoring of all system
He added that technicians, François Lund, Patrice Giono and Piotr Skotnicki had worked
at X Games Tignes since its first appearance there in 2010; all three are certified
Optocore technicians, and were again responsible for realising the design,
implementation and operation of this year’s event.

OPTOCORE APPOINTS SOUND NETWORK AS UK DISTRIBUTOR
Munich, Feb 27th, 2013
German-based optical fibre network specialist, Optocore GmbH, has appointed
Sound Network as its new distributor in the UK.
Based in Central London, and perfectly placed to serve the broadcast, theatre,
install and touring segments of the market, Sound Network see the move as a
logical fit. “The Optocore product line dovetails perfectly with our existing product
mix and we look forward to introducing customers to the benefits of this
impressive solution,” stated director Ralph Dunlop.
Optocore Sales & Marketing Director, Tine Helmle, agreed. “With our growing
penetration of both large scale events and the permanent installation market we
are delighted to be partnering with such an experienced and well qualified
from the left: Maciek Janiszewski-Optocore, Pete Wandless & Peter Holmes-Sound Network, Tine Helmle-Optocore
Dunlop added that his company had held an interest in the Optocore product line
for several years. “In 2012 we felt we had the necessary resources in place to
support a complex system of this type,” he stated. “Serious discussion on
developing a distribution partnership kicked off at IBC Amsterdam in August, and
we are delighted to have now finalised this agreement.”
Optocore will make its debut under the new arrangement on the Sound Network
booth (B55) at the BVE Show at London Excel on February 26. “BVE is the
obvious forum to announce our new relationship, and we will be giving all
relevant professional users the opportunity to discuss the Optocore products and
their requirements for the future.”
At the same time, with Peter Holmes as product manager, Sound Network will be
working closely with customers and dealers to support existing Optocore
deployments, plus developing expanded relationships with system consultants
Summing up, Ralph Dunlop said, “Sound Network is very excited about the new
association with Optocore. With our additional expansion into the area of digital
broadcasting, we are very aware of the importance of reliable, elegant, efficient
and versatile data transfer in the modern audio world.
“We see Optocore as the most pioneering and enthusiastic providers of such
products, together with obvious benefits over and above the competition.
Consequently, we will not only be able to bring Optocore into existing marketing
channels, as we will be addressing many of the same potential end-users, but
embark on strategic communication towards other vertical market segments.”
OPTOCORE TECHNOLOGY SUPPORTS AUDIO FOR THE 2013 U.S. PRESIDENTIAL INAUGURATION
Munich, Feb 20th, 2013
Maryland Sound International Utilizes Optocore Network Rings for Signal Distribution and Monitoring
When audio integrator Maryland Sound International (MSI) was once
again tasked with supplying the main audio system for President Barack Obama’s second presidential inauguration
on January 21, 2013, the company employed two Optocore Networks. MSI, a longtime user of Optocore
technology, a leading choice for powering professional audio, video and data transmission networks in a
variety of markets, including broadcast, post production and AV, chose the networks for their multiple levels of
redundancy and reputation of superior reliability. This marks the third presidential inauguration in a row for
which MSI has chosen Optocore equipment for the critical audio distribution.
With the ceremony taking place on the grounds of the Capitol in Washington, D.C. in January, MSI was faced
with unpredictable winter conditions as well as a long transmission path back to MSI’s Front-of-House position,
nearly 2,000 feet from the last speaker tower. MSI and audio designer Patrick Baltzell needed a way to
distribute audio signals with as few conversions as possible in order to ensure the approximately 1,000,000
attendees of the ceremony heard every word.
MSI chose Optocore Network technology in order to drive the signal chain directly from the Yamaha PM5D
FOH mixing console using Optocore YG2 Yamaha cards that were connected with redundant fiber cabling to
the locations of the loudspeaker processors and amplifiers. This provided MSI with lossless digital
transmission, which is critical in order to properly transport the audio with crisp sound and clarity over such a
long distance transmission path without any glitches.
“The Optocore Networks we put in place for this year’s ceremony certainly made access to all of the amplifiers,
signal processors and overall signal distribution far easier and more reliable than in the past,” says Brian
Bednar, system technician, MSI. “This time around, everything was more streamlined and faster to set up and
tear down at the end of the event.”
The main Optocore Network consisted of one YG2 card in the Yamaha PM5D FOH mixing console connected
to an Optocore DD32 networked AES/EBU device on stage right and another DD32 on stage left. Each DD32
was connected to an Optocore X6P-8/8 analog converter and a Dolby DLP loudspeaker processor via AES.
The X6P converters gave MSI the ability to feed all the devices that were not AES and/or not driven through
the Dolby processor units.
The second Optocore Network consisted of one YG2 card in the PM5D connected to an Optocore DD32R-FX
networked AES/EBU device at delay zone 1 (700 feet away) and another DD32R-FX at delay zone 2 (1500
feet away). Each DD32R-FX was connected to an Optocore X6P-16IN analog converter and a Dolby processor
via AES. Both networks featured redundant fiber connections.
The DD32R-FX proved to be a helpful add-on for this year’s sound system, with its built-in network-wide
Ethernet switch. The Optocore Network allowed MSI easy access to the Dolby DLP loudspeaker processors
and amplifiers located off the main site. With a broad part of the sound system offsite, it was then easier to
maintain control and monitoring of all the devices on the network to see if they were functioning to MSI’s
“It is my role to help the FOH engineer tune the system, so having access to all parts of the system at all times
in order to make changes without my needing to leave the FOH position is invaluable,” says Art Isaacs, project
manager, MSI. “The X6P-16IN converters gave us the functionality to run measurement microphones from
multiple city blocks away back to the FOH position. Using the Optocore system proved itself to us in many
ways. The sound system was extremely quiet due to the all-AES based drive system. Ethernet access to all of
the online devices proved extremely helpful and provided great flexibility. I can only hope that in 2017, we can
continue to work with Optocore systems to further enhance the sound system.”
The relationship between Optocore and MSI goes back for almost a decade. “Optocore has been part of MSI’s
rental inventory since 2004,” says Tine Helmle, director, Optocore. “We are proud to provide MSI with the
solutions it needed to ensure the audio was heard loud and clear during such an important and historic U.S.
event as the presidential inauguration. We look forward to working with them well into the future.”
OPTOCORE APPOINTS PRASE TO BOOST ITALIAN INSTALL
Munich, Feb 5th, 2013
Fibre network giant, Optocore GmbH, has made a significant change to its
distribution arrangements in Italy, appointing Prase Engineering S.p.A to handle
the installation/contractor sector.
Following the direct contact between the two companies at Prolight+Sound in
Frankfurt last year the agreement was confirmed by Optocore marketing director
Tine Helme and Ennio Prase, founder of the Venice-based company.
“This opens up an important new channel in Italy for us,” stated Helmle. “Ennio
and his company fit perfectly with Optocore — they are strong in permanent
install and the AV market, and with our new MADI switches we can hit both these
She added that the catalyst for the appointment had been Duran Audio, which
Prase distributes, and with whom Optocore has a partnership arrangement.
Optocore Marketing Director Tine Helme & Ennio Prase, Founder of Prase Engineering S.p.A
Ennio Prase also welcomed the move. “It’s great that a major player is
recognising the opportunities that exist here in large-scale contracting,” he stated.
“We had known Optocore more for live sound applications in the past but we
invest heavily in pro audio, and we needed a low-latency signal transport system
to boost our infrastructure.”
With a workforce of 30 based in Venice Prase Engineering celebrates its 20th
anniversary this year. Five of the company’s experienced engineers have already
undergone full OCT (Optocore Certification Training) with support engineer
Maciek Janiszewski and the company will now be introducing the various
network solutions via carefully assembled demo racks and a series of open days.
Ennio Prase believes there are huge opportunities for Optocore in Italy —
principally due to the fact that it’s an open platform. ”We are quoting on a series of huge projects including massive multi purpose halls where low latency will be
a key factor. We are already working with transportation hubs (railway stations)
and stadiums. Multi-purpose venues are becoming more and more popular —
with the ability to host a variety of functions under one roof — and an Optocore
network will help increase that versatility.”
Prase says he now plans to increase market penetration by opening a second
office in Milan this spring.
Optocore to showcase new range of MADI switches at ISE
Munich, Jan 29th, 2013
German company cites many advantages of MADI over Ethernet
Optocore GmbH will be using ISE 2013 (RAI, Amsterdam) as a platform to launch the first of a revolutionary new range of dedicated MADI switches from its booth (3-A120).
Announcing the series, Optocore director, Tine Helmle, said, “We believe this to be the best solution for the professional AV market, largely because it is now a common standard — with MADI ports frequently used by manufacturers to offer clients a future-proofed, open platform, with price advantages.
On top of that, says Helme, this solution has many advantages over Ethernet. MADI switches are extremely price efficient, with low latency, low power consumption and fast set-up time — since they have been developed specifically for professional audio and video. These attributes are represented in Optocore’s new range.
The new devices will eventually develop into a complete MADI series of 16-port and 8-port switches, offering 16 x RJ45 MADI ports and 8 x RJ45 MADI ports. The MADI switches are equipped with two redundant high-speed 2Gbit fibre uplinks, which can carry all 16 MADI streams.
The switches will function in MADI over the Cat5 standard. This will be an addition to MADI over fibre and MADI over BNC, while the RJ45 used in the new products introduces a greater flexibility and simplifies the connection.
Each MADI port enables 64 in / 64 out point-to-point connection, as well as 100Mbit Ethernet — and on the same single Cat5 cable there are 128 audio channels and 100Mbit Ethernet.
At the same time the MADI switch enables routing of each individual channel, providing a 640 x 640 matrix for the 8-port switch and 1152 x 1152 for the 16-port. It can also matrix through the uplinks with a number of additional switches, providing not only audio switching and routing, but also functioning as an Ethernet switch.
All new MADI switches are fully compatible with Optocore and SANE — and offer data connectivity to the same level as Optocore FX devices.
Summarises Tine Helmle, “As an open platform, by introducing the MADI switches, Optocore is offering the customer a greater number of options with the best technical features, at the same time providing the lowest cost of ownership.”
OPTOCORE'S UNIQUE MIC SOLUTION GIVES TEATR ROZRYWKI INDEPENDENT GAIN CONTROL
Munich, Jan 18th, 2013
Optocore has played a vital role in the audio upgrade of Teatr Rozrywki, in the Silesian city of Chorzów.
Specialising mainly in staging popular musical productions, last year it undertook a full theatre renovation, and at the end of 2012 completed the modernisation of its audio infrastructure. Commencing with the small 100-capacity auditorium it then extended the refurbishment to the main 577-seat space.
The main challenge facing one of Poland’s leading design consultants, Piotr Kozłowski, and Wojciech Grządziel from integrators, Pracownia Akustyczna, was to provide independent gain control from the FOH and monitor positions. Pracownia Akustyczna (www.akustyczna.pl) has been responsible for all acoustical and electro-acoustical modernisation undertaken at the venue in the last few years. Piotr Kozłowski said, “We have been using digital audio networks in our designs for almost ten years. Many systems today use much more digital kit than analogue, so it is natural to want to use some kind of digital cable to glue all this signal jungle together.”
The obvious solution was for an Optocore X6R-DualMic topology — and thus the consultants based their system design on three X6R-FX-DualMic and nine X6R-TP-DualMic, creating 96 mic connections with independent gain control for every single channel. In addition, two X6R-TP-16LO interfaces were deployed as returns devices from the consoles — with all X6R units located in the stage rack.
For the FOH position the theatre commissioned two Yamaha M7CL-48 desks and these are equipped with Optocore YG2 and YS2 I/O cards that allow direct connection of Yamaha consoles to the Optocore network (the same card combination is used with the M7CL-48 down at the stage end).
As a result, all three Yamaha consoles are able to control the Optocore preamps via the German manufacturer’s unique Yamaha Emulation Mode. The two FOH consoles control the primary channels 1-96, while the monitor console operates selected secondary channels 1-48 or 49-96 — giving the respective sound engineers the unique ability to control the gain independently.
The third section of the system is installed in the amp room, where two Yamaha DME64N processors, fitted with YG2 cards, provide feeds to the L'Acoustics amplifiers, with a further Optocore DD2FR-FX MADI interface enabling the MADI connections.
Lukasz Tobola, technical director of Polish distributor, M.Ostrowski Sp.j., who supplied all the Optocore equipment, is more than satisfied with the solution (as is the theatre). “Optocore is one of our leading brands and well known in Poland,” he said, at the same time confirming that this is the biggest Optocore system installed in the country to date.
“It is a perfect solution for any system — whether large or small — as this flexible, scalable and elegant solution fits almost any application. The core requirement here was to switch to the digital domain, offering the same or better functionality than a traditional analogue theatre system, with a mic splitter.
“Optocore was the only solution that offered independent gain control of the real analogue preamps, without any digital tricks. The DualMic device is simply brilliant and will certainly become our best-seller in the Polish market."
SOUND.COM REVOLUTIONISES INDIA WORSHIP WITH OPTOCORE
Munich, Dec 18th, 2012
A massive spiritual convention, in which 350,0000 worshippers descended on the Indian city of
Jalandhar, in the state of Punjab, over three days, saw the audio relayed over the vast site using an
Optocore network, designed and supplied by the production company SOUND.COM.
Using Optocore’s 2.14 protocol in a ring topology, and a unique combination of single- and multi-mode
fibre they were able to deliver the signal digitally over the large coverage area.
Warren Dsouza’s Mumbai-based live event production company has long been an advanced exponent
of Optocore technology, exploiting large systems for events including the 2010 Commonwealth Games
in Delhi and The Oman Tattoo in Muscat. For this mega peace rally, called the Divya Jyoti Jagriti
Sansthan (DSM 2012), SOUND.COM was selected based on its excellent reputation.
Unique Spiritual Convention, Divya Jyoti Jagriti
Sansthan 2012 , Jalandhar, India
“The organisers first needed the reassurance that we could deliver, and after we had walked the field
2,000 feet from the main stage to see how far and wide we needed to cover the audio, we realised that
with Optocore control and digital transport there would be no problem. With solid networking, extensive
audio processing and superlative measurement this was just another day in the office,” said Dsouza.
Fielding a top tier crew, SOUND.COM designed the system on an entire digital audio transport network
utilising proven and reliable Optocore devices. “This provided the solid foundation and backbone of this
project’s success, assisted by Dolby Lake processors that handled our delay and EQ over the large
distances,” reports SOUND.COM’s MD. A redundant analogue back-up was provided as a precaution.

The PA system, consisting primarily of JBL VerTec, comprised a total of ten sound towers all at an equal
height of 48ft evenly distributed over a distance of 2000ft, with an array length of 12 boxes each. Warren
Dsouza and SOUND.COM chief engineer, Sunil Karanjikar painstakingly measured each stack to ensure
accurate delay measurements over the huge distances.
Each loudspeaker tower was assigned to an OptoRack, which distributed the signal and enabled local
control. The immediate OptoRacks were linked to each other by Tactical Multi-Mode fibre cables and the
redundant loop was closed by a 1.2 Km Single-Mode fibre cable — from the last delay stack back to
FOH. “This is an outstanding feature of Optocore to be able to use a combination of Single- and Multi-
Mode devices on the same unit, providing immense flexibility on projects like this,” notes Dsouza.
Optocore devices used in the installation included DD4MR-FX, DD2FR-FX, DD32R-FX, X6R-FX (16MI),
X6R-TP (16 MI) and X6R-TP (16LO) interfaces.
“Optocore has given us an extremely robust and secure way of transporting broadcast quality audio on
all our projects and the proficiency with which it does this really makes the task easy. I am really looking
forward to the future and many more projects with Optocore,” says Sunil Karanjikar.

The event itself was composed of prayers, discourses and devotional music with the highlight being the
rich baritone voice belonging to His Holiness Shri Ashutosh Maharaj ji. “The moment everyone was
waiting for was to hear his speech over the PA system,” reports Warren Dsouza. “At that point we knew
it was it was ‘mission accomplished’.”
OPTOCORE PROVIDES LARGE SITE COVERAGE FOR KUWAIT 50th CONSTITUTION DAY
Munich, Nov 28th, 2012
Optocore network units played a key role in Kuwait’s 50th Constitution Day celebration
which took place recently along nearly 5km of beach in the heart of Kuwait City. The final
act of the show lasted almost an hour, with a total of 77,282 fireworks, which broke the Guinness World Record for the largest fireworks display ever.
World Record for largest firework, Kuwait
French-based rental company, Gilles Bouvard Events and Entertainment (GB4D) was
contracted by the Kuwaiti government to deliver the audio and lighting system as well as
video transport for one of the largest shows ever staged in the Middle East. The biggest
challenge facing GB4D was the coverage distance along the beach and the associated
problems posed by a sand and water environment.
Since production had stipulated that sound and light needed to be delivered to any point
along the beach, the obvious solution was to use an Optocore redundant fibre based
ring topology — a solution which Gilles Bouvard has been adopting successfully for the
past two years. This provided not only sound to each of 52 Line Array towers along the
5km stretch, but also control of amplifiers and DMX lighting commands.
GB4D Team onsite, final check, Kuwait
The Optocore system was also in use out at sea. Here GB4D designed a second ring
system to provide audio and Ethernet transport to the five cube-shape platforms (24m x
24m x 24m) which were each equipped with lights to create a great visual effect. And the
only way to reach these cubes with control signals was by using Optocore fibre. In
addition there were seven pontoons spaced 250m from each other — all set at a
distance of 400m from shore to sea.
A further challenge for GB4D was to provide video transport to the multiple screens –
with two independent SDI channels transported along the beach. With 30 years’
experience in the sound and lighting business, Gilles Bouvard found that Optocore’s
sister company, BroaMan, offered a perfect solution for his project — with a ring
topology that would distribute two channels to all remote locations.
The cube-shape platforms at daylight, Kuwait
As a result Bouvard needed only a 4-core fibre between each location, which saved not
only the cost of classic copper cabling, but also assuring the best quality of sound,
control and video.
The two Optocore rings ran on different protocols. The first, small ring was based on the
2.14 protocol, since GB4D used older equipment, DD6NEs and a YG2 card. This was
used to provide LAN connections to all five platforms on the sea as well as audio signals
to the Yamaha 01V96 console which was placed on the fifth platform. One DD32R-FX was installed in the FOH position and provided a connection to the second, larger ring.
Elsewhere, DD2FR-FX and DD4MR-FX provided spare fibre MADI and BNC MADI links
to the cubes.
DD32R-FX "in action", Kuwait
The larger Optocore system was installed on the beach. The main requirement for
Optocore was to distribute audio signals to the L-Acoustics loudspeakers from FOH as
well as DMX for the lighting and Ethernet to control L- Acoustics amplifiers.
Loudspeakers were installed in the delay towers 100m apart to cover the whole area
with sound, while Optocore X6R-FX-8MI/8LO units were installed in every third tower —
20 in total — covering the whole distance.
The FOH engineer had complete control over the Optocore patching and every input
from the console could be sent to any loudspeaker. Multiple signals were provided from
two FOH consoles — the main mix from a Midas Pro6 and additional multiple aux
outputs from a Soundcraft Vi6 (one aux per each delay group). Each console was
integrated into the Optocore network with a DD2FR-FX. The ring was also equipped with
an DD32R-FX unit, which provided AES connection to the smaller Optocore ring.
The master control installation at the beach, Kuwait
GB4D took full advantage of the Optocore 2.21 protocol. The big ring provided not only
around 500 audio inputs, but doubled as a transport platform for all control protocols –
DMX and Ethernet-based loudspeaker management system. Each tower was equipped
with steerable lighting, controlled from a FOH light console (with Optocore providing
DMX transport through RS485/422 ports on each unit). To monitor and control powered
loudspeakers, GB4D used the Ethernet switch which is built into the Optocore platform,
thereby reducing the cable count to a minimum with just one fibre between each location.
A BroaMan video and data distribution system was also adopted and GB4D purchased
4-core fibre cables for the show, which allowed the BroaMan and Optocore rings to
share the same cable infrastructure. Although the two systems worked independently,
the cabling cost was highly reduced.
Speaking of his network design, Bouvard said, “I like technological challenges and could
see the BroaMan and Optocore combination as a real solution for network management
of audio, data for light, video and remote control of amplifiers. We were price efficient
cable-wise, packing the whole system in just four fibre strands between locations.
This had been the biggest project ever undertaken by GB4D. Having the new Optocore
2.21 protocol, with 768 audio tracks on a 2 Gb backbone, he said, could easily allow
reconfiguration to accommodate any changes. “This was highly significant when
managing a 5km site.”
Summing up, he said, “With no network there is no show. You can deploy all the
speakers or projectors in the world, but without control and signal, nothing happens.
With Optocore / BroaMan I knew in advance what result I would get. The result was
stunning and everyone deserves congratulations — particularly Maciek (Janiszewski, Optocore support engineer). It was great to know that when a light designer pressed a
button nearly 5km away the projector would turn on without latency.
“In fact the client representing the government of Kuwait and Minister of Communication congratulated us at the end for the quality of the show.”
SIS LIVE IMPLEMENTS FIRST OPTOCORE® 2 GBIT BROADCAST
NETWORK AT MEDIACITYUK
Munich, Nov 13th, 2012
And BroaMan Repeat48 converters boost 24-way fibre video distribution
SIS LIVE, Europe's largest outside broadcaster and uplink provider, has installed a large Optocore fibre ring on a 2 Gbit network, and BroaMan Repeat48 SDI-to fibre converter at the new MediaCityUK in Salford. This major broadcast project was successfully
conducted by the SIS LIVE projects and integration division, under Dave Gill.
SIS LIVE at MediaCityUK, master control room
SIS has now fully occupied three floors of the Blue Tower within the MediaCityUK complex. The 8th and 9th floors now house new broadcast facilities including a master
control room, production galleries, studios, voice-over booths, edit suites and data
Optocore’s contract required the infrastructural design and installation of
seven presentation galleries, two small TV studios, two edit suites, seven VO booths,
new central MCR/CAR, new satellite dish farm, IT CAR and new Text Room data centre.
Clouse up, Optocore DD4MR, TV Studio, SIS Live at MediaCityUK
SIS LIVE also installed an IT infrastructure and house monitoring system on the 10th
floor Seeking to implement a fully redundant network, SIS LIVE broadcast designer Alan Laird believed that an Optocore audio network would offer the best solution given the lengthy
cable runs involved; the fact that his OB colleagues had successfully run an Optocore
system at the 2010 Commonwealth Games in Delhi, underpinned his decision to back
Once the hardware decisions had been made Alan Laird set out to create a vision
routing architecture based on embedded audio distribution, constructed around two 576
x 1152 routers.
The main router is a hybrid design, which generates the MADI audio sources for the Calrec and Yamaha sound desks, while a similar sized monitoring router is used as a
TV Studio, SIS Live at MediaCityUK
“I engineered the back-up system so that should the main router need to be taken down
for maintenance or any other reason the Optocore system would take over,” he
explained. “I also wanted a network that could be used for ad hoc work — so that any
microphone or audio sources could be picked up from anywhere within the production
facility over the Optocore network.”
The Optocore configuration was co-designed by Laird and Chris Payne, in cooperation
with Optocore support engineer Maciek Janiszewski.
Says Janiszewski, “After spending two years designing and specifying this system with
SIS LIVE, we are extremely excited to have delivered a solution based on the brand new 2 Gbit protocol.”
The initial plan had been to use Optocore’s YG2 cards to allow direct connection of the
new Yamaha LS9 consoles and DME64 and DME24 mix processors to Optocore’s
optical digital network — but the high channel count presented a challenge. As a result
the older interfaces made way for Optocore’s new energy efficient and more powerful RSeries
devices while the YG2 and YS2’s were replaced with 20 of the new Y3R-TP
cards, connected to various FX devices. All Optocore equipment was supplied by Tyrell.
The new Optocore architecure is based around 12 Optocore IDs and uses 648 inputs,
realised from 19 Optocore units. The first phase includes five DD4MR-FX MADI
converters and eight X6R-FX, a DD32R-FX main interface and 14 x Y3R-TP. In the
second phase SIS LIVE will purchase the remaining five DD4MR-FX units and six more
Y3R-TP’s once the other galleries are built. The Y3R-TP cards are fed from the SANE
port on the X6R-FX or DD4MR-FX converters.
SIS LIVE also specified Optocore’s BroaMan video broadcast routing solutions, having
been introduced to Optocore’s sister company and become aware of the custom solution
provided for SVT in Stockholm.
Faced with a reduced timescale to install the galleries (picture on the left) on an HD / 3G backbone and
concerned about cable lengths, SIS LIVE were impressed that the company’s fibre
solutions had extended to video, and noted the smooth operation and cost efficiency.
As a result 22 Repeat48 units, which convert up to 24 SDI or MADI coaxial signals to
optical fibre within a 1U device (equipped with dual redundant power supplies), were
commissioned — working within a Miranda vision distribution environment. The multiple
24-way fibres have been installed to each production room with a Repeat48 at each end,
and Ethernet multicore cable and PSN 25 for the GPI’s.
This topology has more than satisfied the distribution requirements of an installation that
will be maintained by SIS LIVE’s broadcast engineers.
“We are delighted that the SIS system is the first broadcast installation that takes full
advantage of the 2 Gbit protocol,” summarises Maciek Janiszewski. “The nice aspect
about it is that it is not only the invisible core that seamlessly runs all audio through the
facility, but SIS also uses all software advantages with the matrix and remote control of
The overall project director was Jason Barker while Jenkins Design and ISG were
commissioned to complete the building works with Fairbrother installing the electrical
and air conditioning systems. Gary Plowman, Senior Associate, Marquis Consulting LLP,
acted as consultant on the electrical and air conditioning system.
OPTOCORE SETS UP IBC NETWORK
Munich, Oct 18th, 2012
Optocore partnered with its new sister broadcast company, BroaMan to present a
real tour de force at this year’s IBC Show (held at the Amsterdam RAI).
According to the company’s Application Engineer, Kári Eythorsson (picture on the left) customers
returned to the booth three or four times to discuss what Optocore/BroaMan tools
could do for their applications, assisted by pens and sketchpads.
A key feature was that, as at previous shows, Optocore/BroaMan set up an
active bi-directional audio, video and intercom link between their stand (in Hall 8)
and Clear-Com (in Hall 10), using the Optocore X6R and V3R-FX-INTERCOM
As for Broaman, the main product focus at the show was the new addition to the
BroaMan DiViNe (Digital Video Network) portfolio. This was the V3R-FXINTERCOM-SDI, which conveniently packs up to six 3G/HD/SD-SDI I/O’s and
CWDM multiplexer, four ClearCom (or RTS) intercom ports, four Ethernet ports
and four serial ports into a 1U device — neatly combining DiViNe, Optocore and
Booth, Optocore/BroaMan at IBC 2012
Many partners brought clients who immediately invested in both the Optocore
and BroaMan concepts. Summarised managing director, Tine Helmle, “The
feedback was overwhelming and quality of clients extremely high. The show was
100% successful, and we now have a number of new projects to follow up
directly related to the show.”

OPTOCORE ADDS MORE RINGS TO THE LONDON OLYMPICS
Norwest/Delta Sound set up large stadium PA/broadcast fibre transmission for
Munich, Sept 10th, 2012
The awe-inspiring — and completely distinctive — Opening and Closing Ceremonies, which
spectacularly book-ended the London 2012 Olympics, was a triumph for the respective artistic
directors, Danny Boyle and Kim Gavin.
Breathtaking fireworks over Olympic Stadium, London 2012
Described as the most creative yet, to ensure the realisation of these ambitious concepts, the
sound and lighting designers were also faced with enormous technical challenges.
Specialising in this scale of event production for more than a decade, Australian company Norwest Productions again teamed up with their UK partners Delta Sound to provide the
necessary Optocore fibre signal transport, custom RF solutions and LAN networking. This
sophisticated connectivity realised the sound design conceived by fellow Australian Scott
Willsallen (of Auditoria) — another with a string of Games Opening/Closing events on his CV —
in conjunction with theatre sound designer, Bobby Aitken.
Norwest’s project manager, Andy Marsh, knew that the network system required for a new
80,000-capacity Olympic Stadium would present challenges. “We needed to overcome difficult
cable runs,” he said. “The cable installation took us in excess of three weeks and was more akin
to installing cable permanently into a venue. On top of this, the inclusion of many fully live
musical acts — adding further size and complexity to the Optocore and backup systems —
placed a considerable load on all the experienced audio engineers involved.”
Optocore has long been at the heart of Norwest’s main digital systems — and more than 50
devices were deployed in an inventory shared with Delta Sound.
"Sound control", Olympics, London 2012 (click onto picture to enlarge)
Since the specification had called for all Optocore ‘R’ series devices, Norwest purchased a
number of these new energy-efficient converters to accommodate the design’s high channel and
node count. They added quantities of DD4MR-FX, DD32R-FX, X6R-FX-8AE/8MI, X6R-TP-
8AE/8MI, X6P-16IN devices to their inventory — these offer increased features and efficiency,
reduced carbon footprint, power consumption (of 40%) and cost. Delta Sound also purchased a
quantity of DD4MR-FX,DD2FR-FX, and X6R-FX devices for the event.
“Optocore is unique in its ability to matrix a high channel count over large distances, plus
providing the redundancy of a ring network,” states Marsh. “Most significantly, it is extraordinarily
robust and reliable, which is essential to a show that is playing to 80,000 people live in the arena
and four billion watching on TV.” The integration necessary to meet Auditoria’s detailed and dual-redundant design involved
deploying multiple Optocore fibre networks, with full analogue back-up, principally for the main
PA and Broadcast systems.
The main 24-node ring collected and distributed all inputs and outputs on a 2Gbit network to a
myriad of broadcast and PA locations, and Optocore also delivered both PA and monitor feeds,
plus timecode and programme. In total there were 696 I/O channel feeds within the Optocore
Opening Ceremony,"green rural life", Olympics, London 2012
This was one of the first uses of the German company’s new 2.21 protocol, which enabled 2Gbit
bandwidth operation — and was crucial to meet the main requirement of a high channel count.
Another unique feature of the set-up was that Norwest were using all 24 ID’s — taking
advantage of the maximum capacity of the fibre ring. They also used a quantity of Optocore’s TP
devices, which provided a Cat5 extension of the ring.
With multi-mode distances of up to 350m between nodes, and single-mode distances running
anything up to 1000m between nodes, the scale of the complete fibre network was in excess of 5km (with Dolby Lake processors providing the main system switchover between networks).
The broadcast ring, meanwhile, tied the main system to the Delta Media truck for all necessary
I/O. Delta Media delivered downstream mixes of playback, live and atmos mics to both CTV and
OBS for their broadcast of the ceremony.
In the transmission path, all signals were converted to digital on entering the Optocore
environment, while the back-up system ran analogue from the DiGiCo console SD rack outputs.
The feeds were delivered via AES to a massive FOH PA comprising entirely L-Acoustics
components, with 220 VDosc, 100 Kudo, 55 Arcs, 88 SB28 subs and some 12XT fills — all
driven from LA8 amplifiers.
In summary, Andrew Marsh can reflect on a highly successful implementation in which Norwest
confronted numerous challenges along the way — including the siting of some of the equipment.
But then again these were unique shows.
Opening Ceremony,"Industrial Revolution", Olympics, London 2012
The Opening Ceremony was described as “madcap, surreal and moving” — evolving historically
from green rural life via the belching chimney stacks of the Industrial Revolution to the internet
age. The second was billed as ‘A Symphony Of British Music’ and tipped as 'the best after-show
party that's ever been’, featuring 4,000 artistes, with cameos by The Spice Girls (performing on
top of black London taxis, travelling around the athletics track) and Monty Python’s Eric Idle providing some of the more memorable moments.
Marsh credits his own crew, and in particular Justin Arthur (Optocore & Patch Engineer), as well
as the Delta Sound crew, led by overall project manager Steve Lutley, plus Senior Systems
Engineer from Autograph, Rob Tory.
“We all worked seamlessly together to make this a huge success, and the relationship between
us could not have been better.”
OPTOCORE'S ADVANCED FIBRE NETWORK FOR NEW TOKYU THEATRE ORB
13th floor auditorium at Tokyo's Hikarie Tower is highest stage in Japan
Munich, August 1st, 2012
Optocore’s advanced fibre network for new Tokyu Theatre Orb 13th floor auditorium at Tokyo’s Hikarie Tower is highest stage in Japan
A brand new purpose-built musical theatre has opened in Japan — situated
between the 11th and 16th floors of the new 1.27 billion dollar 34-storey Shibuya
Hikarie glass tower in Tokyo.
Connected to the Shibuya Station, Tokyu Theatre Orb’s first production was of
West Side Story, with signal distribution via an Optocore fibre backbone provided
by the German company’s Japanese representatives, Acoustic Technical
Laboratory Inc (ATL).
This ambitious project was floated by owners, the Tokyu Corporation back in
2008, and ATL became involved after Yamaha Sound Systems Inc (Yamaha SS),
the biggest sound system construction company for theatres and auditoria in
Japan, had specified an Optocore solution in their proposal.
Tokyo Hikarie Tower, Japan
According to Tetsushi Hirai of Yamaha SS, the client had specifically requested
the optical fibre backbone in view of the long distance transmission of dialogue
and music between the 1972-seat auditorium, stage and mixing control room as
well as the data transmission between floors — including the Hikarie Hall A & B
on the 9th floor.
Auditorium, Tokyu Theatre Orb at Hikarie Tower, Tokyo,Japan
Yamaha SS constructed the digital architecture around nine Optocore DD32R-FX primary interfaces, connected to nine X6R-TP-16LO and nine X6R-TP-16MI
converters — initially linked via AES D-Sub 25, although this will transfer in due
course to Optocore’s SANE (Synchronous Audio Network plus Ethernet) protocol.
The Optocore system derives its clock signal from a Rosendahl Nanoclocks
master clock generator.
Outputting to a Meyer Sound M’elodie line array system (with 600-HP subs), the
Optocore system can be divided into three smaller systems: the first is mounted
in device racks in the control room; the second is mounted in a rack on the stage;
and the third is mounted in a mobile rack that can be freely moved within the hall,
allowing it to be connected to various optical connector panels, while the hall
itself contains a network of optical fibres that are patched for use over the 256-
The signal I/O for the control room and the stage systems are connected to an XLR patch panel, and connections are made depending on the requirements of
the event being staged. Within the control room, some of the signals are
generally patched to a Yamaha PM5D or DM2000 console via AES, while the
mobile rack is used in combination with the DD32R-FX and the converter unit,
wherever it is needed.
While Shibuya is the heart of Tokyo’s busy shopping district, Hikarie itself is seen
as a new cultural hub. The word itself means ‘Towards the light’ — and the light
in this instance shines from Tokyu Theatre Orb’s highest stage in Japan …
located on the 13th floor of Hikarie.

Yasuhito Terada, a technical director at Tokyu Theatre Orb, confirms that in
addition to the permanently installed system, they are also looking to set up a
temporary independent system that can be used either for stage I/O, or to
connect between FOH and the stage monitors.
Meanwhile, the Optocore digital signal flow will continue to provide the new
theatre with an elegant and flexible solution.
OPTOCORE APPOINTS AVSC IN THE PHILIPPINES
Munich, July 30th, 2012
Optocore has appointed Audio-Video Solutions Corporation (AVSC) as its new exclusive
distributor in the Philippines. The company will be responsible for marketing the German

projects, rental/touring applications and the broadcast market sectors, according to
AVSC’s sales manager, Wayne A. Gutor.
AVSC product managers, Wayne Gutor and Janice Villamil, with general manager Michael ‘Mike” Sanchez — and Optocore racks
“With the addition of Optocore to our product portfolio, AVSC will be recognised as a
total system solution provider for PA and AV markets in the Philippines,” he said.
Faced with an increasing demand for a reliable networking system, AVSC approached
Optocore back in February this year. Once the deal was agreed they wasted no time in
ordering a series of demo racks containing more than 40 interfaces, including DD4MRFX,
DD32R-FX, V3R-TP-INTERCOM and various other V3R and X6R converters.
According to Gutor, Optocore will make an immediate impact in various large church installations, and has been earmarked for a 5000-capacity Convention Center / Worship
Hall, Entertainment City (with large Casinos and Theaters), an Amusement Park and a Broadcast News Studio. In fact the broadcast segment will become a core market.
“We see the flexibility and compatibility of the Optocore system, in use with other major
pro-audio brands such as DiGiCo, Avid, Yamaha, Soundcraft, Clear-Com, Telex, RTS
and Neumann, as a major advantage, along with Optocore’s ability to build multi-node
large networks via optical fibre and Cat5/6 cables,” he continued.
Technical training has already been put in place as a precursor to joining the OCT
Certification programme, and AVSC will appoint a dedicated Optocore product manager
supported by an engineering department for technical support and after-sales-service.
The brand will be formally launched during their biggest annual pro audio show, PALMM
Commented Optocore Director of Sales & Marketing, Tine Helmle, “We are delighted to
have found a partner of the calibre of AVSC in this region. I am very optimistic that we
will achieve great sales in a short period of time.”
Summing up Wayne Gutor stated, “AVSC is excited by the opportunity to develop the
business potential of Optocore here in our country. As stated previously, the Optocore
system will enable AVSC to become a total system solution provider for PA and AV
markets here in the Philippines.”
BROADCAST ASIA OPENS NEW MARKETS FOR OPTOCORE/BROAMAN
Munich, July 05th, 2012
The recent Broadcast Asia expo in Singapore proved fertile ground for Optocore and its sister company, BroaMan.
BroaMan devices, part of booth at Expo:
The four day exposition for Digital Multimedia and Entertainment Technology was
held at Suntec Singapore, where the German manufacturer shared a booth with
one of its key partners, Clear-Com.
Man, support engineer, Maciek Janiszewski stated,
“This was a new show appearance for us, and in addition to opening the
broadcast market for our respective technologies, it showed the level of
cooperation we enjoy with our strategic partners.”
Optocore operates an open OEM policy, and two years ago formed a strategic
alliance with Clear-Com, resulting in the release of the new V3R-FX-INTERCOM and X6R-FX-INTERCOM. Developed specifically for the company, both units
were integrated on the booth with Clear-Com’s Eclipse digital matrix in the Vseries
Optocore later worked with fellow intercom provider, RTS, to develop a similar
network solution compatible with their devices.
Also on display at Broadcast Asia were BroaMan’s new DiViNe video, audio and
data system consisting of the three main frames — Route66, Repeat33 and Repeat48.
Janiszewski could not have been more positive about the company’s
participation. “We believe that this show will prove to have been extremely
successful in opening a new market for our operations,” he said.
OPTOCORE SETS OUT FAR-REACHING AGENDA AT INFOCOMM 2012
Optocore GmbH has a wide-reaching agenda at this year’s InfoComm 2012 in Las
Vegas later this month.
Munich, June 26th, 2012
Principally, the German fibre network specialist will be announcing a technical
collaboration with Duran Audio see separate release, please — having developed the new
DM1-TP interface connectivity for the AXYS® Intellivox powered loudspeaker range,
enabling it to operate within their SANE networks.
At the same time the company will be celebrating the fact that Optocore Certification
Training (OCT) has been approved for InfoComm’s CTS renewal programme. Each
attendee who completes the training and test will receive three InfoComm CTS Renewal
Units toward their CTS, CTS-I, CTS-D re-certification.
The company also applauds the pending release of InfoComm’s new international
standard on energy efficiency (InfoComm 4:2012 DS-1:Audiovisual Systems Energy
Management). This defines and prescribes processes and requirements for ongoing
power-consumption management of audiovisual (AV) systems, identifying requirements
for the control and continuous monitoring of electrical power for audiovisual systems,
whereby power is conserved whenever possible and components operate at the lowest
Said Optocore founder Marc Brunke, “We are delighted to note InfoComm’s commitment
to both training and energy efficiency — two areas which we take seriously.
“Efficient design has always been what Optocore has strived for. Optocore products are
extremely energy efficient — for example the DD32R-FX requires only 8W while many
other solutions require hundreds of watts, and require larger UPS and HVAC services. I
am delighted to see that the industry has started to take note of the important subject of
At the same time he noted that recognition of Optocore’s OCT programme would provide
a major boost to the certified training initiatives that the company has had in place for
some time. “Offering CTS renewal points towards the maximum required for
recertification will provide our customers with a huge incentive,” he said.
Optocore will also introduce its new sister company, Broadcast Manufactur (BroaMan) on the same booth (#C10350) — with its proprietary DiViNe (Digital Video Network) technology focused on the broadcast market.
DiViNe is designed to provide routing and repeating, as well as transport and distribution
of multiple professional SDI video signals over fibre-based infrastructures, preconfigured
to customer requirements. The system can be constructed from a series of DiViNe
building blocks (such as Route66, Route33, Repeat66, Repeat33 modules), to create a
flexible, multiple channel distribution system with or without routing, while Repeat48 is a
standalone SDI to fibre converter (with or without WDM multiplexers).
To this family BroaMan will be introducing a new device at InfoComm 2012 — the
DiViNe V3R-FX-INTERCOM-SDI. Please, see separate release on http://www.broaman.com. This unit is based around the
Optocore V3R-FX-INTERCOM with the capacity for up to six 3G/HD/SD-SDI inputs and
outputs and a CWDM multiplexer (all contained in a compact 1RU device). As with all
BroaMan DiViNe products they are configured with video I/O and CWDM — according to
the wishes of the customer. The DiViNe V3R-FX-INTERCOM-SDI seamlessly integrates
into DiViNe, Optocore and SANE networks.
BroaMan will present a live demo, connecting the displays of BroaMan, Optocore and its
technical partner Clear-Com — similar to the network constructed at the NAB Show
earlier this year. The DiViNe V3R-FX-INTERCOM-SDI will be located on the Clear-Com

New DM1 interface will bring powered Intellivox speakers into the SANE network
Making its debut at InfoComm 2012 will be the new Optocore DM1-TP digital audio
interface for Duran Audio’s Intellivox range of AXYS® products — marking the latest
technical partnership formed by the German fibre network specialists.
In a joint statement, the respective founders of the two companies, Marc Brunke (Optocore) and Gerrit Duran said, “This product owes its practical implementation within
an Intellivox system to the close co-operation between the two R&D teams.”
The DM1-TP is designed to provide SANE connectivity to powered Duran Audio
loudspeakers, allowing for seamless integration of the company’s loudspeakers into
synchronous, low latency, redundant Optocore and SANE networks. Offering a unique,
non-proprietary open standard transport platform SANE is the first fully synchronous
CAT5 network solution for streaming and transmitting data in real time.
In addition to the synchronous, low latency digital audio distribution, DM1-TP will provide
the Intellivox range with all the other benefits of SANE, including 100 Mb/s Ethernet
audio distribution, dual-redundant ring connections, and interfacing to Optocore FX and
The introduction of the SANE network will bring significant benefits to system designers,
installers and end users. On larger Intellivox installations there will be a significant
saving in both the cost of cable and labour, whilst the wealth of additional features will
reduce the need for additional processing devices in the system. This once again proves
that Intellivox devices not only provide great control of the array’s directivity but also the
Either redundant point-to-point (star) or daisy-chain topologies are supported (point-topoint
requiring an Optocore SANE capable device for a connection to each DM1-TP
equipped Intellivox); redundant option offers automatic switch-over to the secondary port
in case of failure of the primary port. Daisy-chain with loop-end closing offers a
redundant ring topology (with no third party switching required). Other features include
low-jitter word clock distribution using standard Optocore solutions and automatic master
DM1 firmware and internal logic updates over Ethernet are supported, as is standard
Intellivox RS-485 interface, while system control and monitoring by AXYS WinControl
takes place over a SANE serial bridge, with 8 or 16 digital audio channels routable to the
DSP in the Intellivox.
Other peripherals include external fan control output for connection to the Intellivox 'rainhood',
while an Ambient Noise Sensing microphone signal can be routed to the SANE
The new interface module can be mounted in the following Intellivox products: AXYS®
Intellivox DC/DS 115, DC/DS 180 and DC/DS 280,
said Optocore’s North American support engineer, Kári Eythorsson CTS-D, “We are
delighted to be adding Duran Audio as a technical partner with the release of the DM1-
TP module — and hope this is the start of further things to come.”
And Duran Audio International Sales and Marketing Manager, Max Lindsay-Johnson,
added, “We see this collaboration as just the first step in making the whole AXYS®
range available with the Optocore and SANE interfaces in the future.”
BROAMAN/OPTOCORE MAKES SUCCESSFUL NAB 2012 DEBUT
Redundant audio/video/data network set up with Clear-Com
Munich, May 30th, 2012
Optocore GmbH’s ambitious concept of networking its BroaMan/Optocore booth with Clear-Com, to provide bidirectional audio, video and data transmission, paid handsome dividends at
this year’s NAB Show in Las Vegas.
Optocore & Clear-Com devices
Support & Applications Engineer, Kári Eythorsson explained that a fully redundant network was
in operation throughout. At the Clear-Com booth a four-device Optocore net-work was stationed,
with a DD4MR-FX connected to a Clear-Com Eclipse inter-com matrix frame that featured the
new Clear-Com E-MADI interface card. At the same time, an Optocore V3R-INTERCOM-FX and
a X6R-INTERCOM-FX networked two Eclipse frames and a HelixNet base station.
The Clear-Com booth additionally featured a special version of Optocore’s V3R-INTERCOM-FX with four SDI outputs and an SDI input; a remote controllable Q-Ball camera was connected to
the input of this device and fed to a BroaMan DiViNe Route 66 router, located at the BroaMan/Optocore booth, with the camera output connected to a monitor and the camera itself
controlled by a CCU over the network.
In addition, a Clear-Com V-Series IP panel was connected to the network, allowing
BroaMan/Optocore personnel to seamlessly communicate with the Clear-Com booth. The
connected system then fully displayed Optocore products, including a 48-16 analogue stagebox
(built from X6R devices), a Yamaha DM1000 mixing console and Optocore DD32R-FX, DD4MRFX
and DD2FR-FX interfaces.
But the real story was the full trade show debut Optocore was able to give to its new broadcast
brand, BroaMan. Setting the scene for customers in his territory, Bill Coons who heads up
Optocore North America, said “BroaMan’s DiViNe [Digital Video Networking] is nothing less than
Optocore for video.
Optocore/Broaman booth at NAB-Show 2012
“Considering that almost all other digital audio transport manufacturers are limited to low channel
count, long latency and simple point-to-point capability, it’s easy to see how Optocore has
changed the industry. We led the fibre optic movement in creating multiple format delivery
systems via multiple node networks for upwards of 1,000 audio channels. We’ve now
accomplished much the same thing for video with the creation of DiViNe.”
Optocore/Broaman booth at NAB-Show 2012
With 80 channels of SD/HD/3G-SDI video transport and routing on a 240Gb network that allows
virtually unlimited system deployment, DiViNe offers customised solutions, yielding results
unattainable with existing technology.
In addition, the DiViNe protocol allows Optocore audio products to integrate seamlessly into the
environment, to add a full audio complement of analogue, AES and MADI connectivity making it
a single complete audio-video solution — as demonstrated at NAB.
The broadcast world responded to this, and Optocore sales representative, Luke Barry, said he
was confident that business would be written from the show. “We had some quality clients visit
our stand, including several major US and Canadian networks, who were very interested in what
we had to offer, and we also had approaches from potential distributors.”
PAYING TRIBUTE TO AR RAHMAN WITH OPTOCORE
SOUND.COM supports German Film Orchestra Babelsberg over five Indian cities
Munich, May 8th, 2012
Any concert dedicated to multi-instrumentalist and record producer AR Rahman —
described as the world's most prominent and prolific film composer — requires a sound
quality nearing perfection.
Meeting this audio challenge at the recent Classic Incantations concerts — presented by
the German Film Orchestra Babelsberg across five Indian cities — were SOUND.COM.
Orchestra Babelsberg, choir & solists: KM Music Conservatory, Chennai, India, Matt Dunkley, Conductor
This was the first ever tribute to an Indian composer from the western world, and
working with Core Networks & Rapport Global, SOUND.COM were extremely proud to
be associated with this distinctive production.
The Orchestra, conducted by Matt Dunkley, performed original scores and film music
written by the Indian maestro — accompanied by the choir and soloists from his own KM
Music Conservatory in Chennai.
Sunil Karanjikar, Holger Schwark, Waren Dsouza, Joel Dcruz
Once again the sound crew relied on their Optocore network to transmit pristine signals.
SOUND.COM’s Sunil Karanjikar and Joel Dcruz toured the country with FOH mixing
engineer Holger Schwark (on a DiGiCo SD10), playing back to back shows, while
SOUND.COM’s MD, Warren Dsouza acted as stand-in systems engineer for the Delhi
and Kolkata leg of the tour.
The Optocore solution was used where the Input sources from the stage exceeded the
48 Mic pre amps available as standard on a Digi Rack. The additional 14 channels were
picked up by an Optocore X6R-FX 16MI and transported to the SD10, interfaced
coaxially to Optocore by means of a DD4MR-FX.
The DD4MR-FX and a DD2FR-FX also simplified a relatively tough job of multi-tracking
each concert on two computers (one used as backup), confirmed SOUND.COM head of
engineering, Sunil Karanjikar. Both computers used RME MADIface interface units to the
multi-track and all inputs on the SD10 were MADI mirrored on the Optocore DD4MR-FX
and DD2FR-FX to implement this solution. “This facility allowed us to multi-track a full
56ch system using just one fibre and one coax pair each for the two redundant systems,”
The Bangalore show, where production fielded four main hangs of JBL VerTec, 36 delay
clusters of paired VRX932LA boxes and a final row of SRX712M boxes, proved
particularly challenging. “This was something of an audio milestone in India — and the
fact that it was successfully executed was down to the Optocore node racks and Harman
HiQnet System Architect, which managed the Crown I-Tech HD12000 power amplifiers,”
said Warren Dsouza.
In Bangalore, the Optocore DD4MR-FX also collected outputs from the SD10 to be
routed to four SOUND.COM OptoRacks, with each OptoRack consisting of a DD32R-FX
and a X6R-FX 16MI. AES outs from the DD32R-FX fed the Crown ITech HD amplifiers,
which were driving the PA and delay clusters, while the LAN and SANE ports were used
to transport Ethernet data from the master computer to the Crown ITech HD racks,
allowing for full system control (including delay and EQ) for each cluster. Optical
isolation allowed SOUND.COM the freedom to use multiple power sources in the venue,
keeping cable runs to a minimum.
Warren D’Souza stated that the tour had been executed to the highest level, while
Sunil Karanjikar concluded, "The Symphony tour was personally very gratifying as we
exploited technology to its maximum potential. This was especially true of the Optocore
fibre optics, CAT5, AES and analogue, which handled all the audio transport, and the
combination of optical and electrical MADI for the multitrack recording and replay. This
was all due to the solid platforms Optocore and RME provided us with.”
Added Holger Schwark, “I think we had five very good shows, all totally different in
circumstances, and I am extremely grateful for all the support we received, especially
from SOUND.COM’s audio crew.”
OPTOCORE AT HEART OF COMPLEX FINNISH THEATRE UPGRADE
Munich, April 12th, 2012
Hedcom and msonic advanced digital design prepares Svenska Teatern for
premier of new hit musical, Kristina från Duvemåla
The Svenska Teatern, a Swedish-speaking theatre in Helsinki, has taken delivery
of an Optocore system as part of a complete new technical infrastructure. This
was designed to coincide with the Finnish premier of Kristina från Duvemåla —
the hit musical written by former ABBA members Björn Ulvaeus and Benny
Andersson — at the end of February.
The Optocore fibre loop will form a digital backbone (with SANE extensions) for
signal distribution to the amp racks, TTA Stagetracker localization and Yamaha
processing. It also includes MADI converters.
Svenska Theater in Helsinki
The equipment was supplied by the company’s Finnish distributor, msonic, who
also assisted the Theatre’s long-serving technical manager Andreas (Stanley)
Lönnquist — and the theatre’s consultants (including Santtu Sipilä) — with the
design and specification of the highly complex audio networking system, as well
as the tender document.
Locally based integration company, Hedcom Oy, had
the capabilities to implement this within the time frame and were contracted to
carry out the installation following their successful bid.
The digital infrastructure itself was mainly designed by Janne Sivonen
and Lönnquist along with Tero Hölttä from msonic and Santtu Sipilä.
Also assisting with the design was Optocore’s support engineer, Maciek
"Close up" Optocore devices at Svenska Theater, Helsinki
Optocore devices used in the installation include quantities of DD32R-FX
providing AES/EBU I/O, X6R analog converters, DD4MR-FX and DD2MR-FX
dual MADI devices, compatible with Optocore’s Cat5-based Sane platform.
This famous theatre, with its striking red and gold architectural décor, was
originally designed by Russian architect Nikolaj Benois and built in 1866. It is the
national stage for the Swedish speaking minority and has hosted many concerts
and repertory theatre productions during its illustrious history. The great hall
seats around 600 and a second studio theatre, around 100.
The decision to renovate the theatre was made several years ago with part of the
previous technical equipment infrastructure sold or decommissioned, and part
redeployed. However, Lönnquist has kept faith with d&b audiotechnik
loudspeakers, now upgrading to the T-series, which will be the main sound
reinforcement component among the 100-plus d&b speakers specified, while the
former C-series will be relocated to the second room. DiGiCo digital consoles
have been installed in both the FOH and monitor positions.
Stated Hölttä, “The main aim was to keep the entire signal path digital, in order to
maintain the audio quality and keep the latency as low as possible.”
Which is where Optocore comes in. The German manufacturer delivered a
number of devices in order for the network topology to be built around two
independent redundant rings.
At front-of-house is a DiGiCo SD7T console, with EX-007 Sidecar and six SDracks,
while the monitor desk is a DiGiCo SD10. Three MADI units add the open
standard connectivity to the DiGiCo environment in one Optocore-based loop.
The second, pure Optocore loop provides analogue, AES/EBU and MADI inputs
and outputs throughout the entire building. The system is also equipped with
multiple SANE-enabled Y3R-TP cards, providing digital channels to the Yamaha
DME64 processors, while two DD32R-FX devices feed the amplifiers in the amp
The Optocore loops are connected by two DirectOut M1K2 MADI routers, each
loop compatible with Optocore’s 1Gbit network. The entire system has been
designed to carry almost 1000 audio input channels.
Meanwhile, development remains ongoing, and future plans are expected to
include a production/recording room within the facility.
Kristina från Duvemåla, meanwhile, looks set for a long run. The musical itself is
based on a series of four novels, collectively known as ‘Utvandrarna’ (‘The
Emigrants’) by Swedish author Vilhelm Moberg, detailing a family's povertydriven
migration from Sweden to America in the mid-19th century.
OPTOCORE GETS PUNK'D
Munich, April 5th, 2012
Coffey Sound’s New Intercom System takes Film/TV Location Work to Next
When the ninth season of Punk’d hit the airwaves, few may realize the massive
effort required to capture the excitement of MTV’s celebrity driven hidden camera
To help streamline those operations, Gary Vahling of Coffey Sound, a Trew
Audio company, long recognised as one of Hollywood’s leading sources for audio
equipment in the entertainment industry, relied heavily on Optocore’s latest
To deliver the action amongst the production crew, Optocore V3R-FX-Intercom
and X6R-FX-Intercom network devices were paired with Clear-Com’s V12-PDX4
display panels connected to a PiCo frame, which are part of the Eclipse Digital
Matrix product line.
Optocore’s V3R-FX and X6R-FX interfaces provide four and eight ports via single
module or multimode fibre respectively or CAT5 ‘SANE’ (Synchronous Audio
Network plus Ethernet) ring connectivity that allows intercom to travel over the
entire Optocore audio network.
Along with fibre audio muxing solutions, to and
from Clear-Com’s remote panels, these units can also send and receive 4-wire
audio around the connected ring. Better still, redundant LAN for IP panels and/or
PC Management can be made from anywhere on the network.
Six different interfaces were constructed by designer Gary Vahling – a remote
camera rack, video rack, a director’s table, RF Mic rack, along with Intercom and
Mix racks. The evaluation process needed to prove a vastly reduced set-up time,
with simple plug and play, improved sonic fidelity and greater functional flexibility.
“I could see immediately that the plug and play facility would make for superfast
setup, which reduces productions costs,” noted Vahling. “And it went much
further than that. The integration of the Optocore improved the quality of the
entire audio package. The noise floor was reduced substantially, the dynamic
range was increased, and the advantage of audio networking came into play.”
Optocore ticked all the boxes, at the same time demonstrating the vast amount of
time saved using ‘one click’ reconfiguration changes for different scenes without
rewiring. “The Clear-Com integration also included reduction of external cabling
and increased sound quality in the communications circuits, continued Vahling.”
Director of Optocore North America, Bill Coons, added, “This location sound
solution provides a faster, quieter, smaller, lighter and less expensive option than
they had previously. With this, fibre intercom for location production has now
become a reality.”
Close up, Optocore in "action"
In addition to the Optocore intercoms and Clear-Com display panels, Sennheiser
MKH 8070 microphones with MZD-8000 Digital Modules were used with
Neumann DMI-2 Digital Microphone Interface to fully take advantage of digital
capabilities of the fibre optic audio network. A Yamaha O1V96 with Optocore
YG2 card mixer was used as the interface’s centrepiece alongside a Sound
Devices 788T for the show’s multi-track recording.
Punk’d production sound mixer, Sean O’Malley, is pleased with the fast set up
times and the overall sound quality. “The gear has performed flawlessly on set,
helping to herald in some amazing audio tracks and provide seamless
communication within the crew. Communication is such an important factor
during our reveals, if it fails, the entire episode could collapse,” adds O’Malley.
Since Coffey Sound provides packaged support systems for both large and small
productions, the pairing of Vahling’s long term relationship with Punk’d made the
producer’s decision to work with Coffey Sound that much easier.
solution had exceeded all expectations, says Vahling. “It has really brought this
package to the next level with its ability to operate as a plug and play system. It
has also significantly improved the workflow of the audio crew — and the sound
quality project being sent to post is better than ever.”
OPTOCORE UPGRADE SERVER/CLIENT SOFTWARE
Munich, April 4th, 2012
Back in 2010 Optocore developed Server/Client software that would facilitate
simultaneous network control from multiple computers. In other words, for the
first time different personnel, with their own computers, could initiate
simultaneous changes for different devices in the network.
Optocore has since
developed the software, continually adding new features and devices.
The functionality will be enhanced further with the release of the new software,
This will provide a number of new features, the two most important ones being to
give users the ability to daisy chain up to four X6R-TP devices by Cat5 from the
SANE port of a DD32R-FX, along with a fibre diagnostic.
With the new Software release a ‘Health’ feature is also available for each device
connected to the network — and this can be accessed from the Network Tree by
right-clicking one of the devices. A status of the chosen device is displayed,
providing information about the optical links status — such as the transceiver
type used for each link, the optical output and input power, ID of the device which
is connected to each link and the connection status (linked or not linked).
It also informs about the device performance — the main board voltages, PSU
status and the main board temperature — and alerts when the parameters
exceed the normal values.
“The ‘Health’ option is useful for troubleshooting the links and the devices — it
will save us and our customers a lot of time and effort,” says Optocore support
engineer Maciek Janiszewski. “Many of the support calls are caused by a fibre
infrastructure problem, but now it can be easily eliminated.
“Finding neighbour devices in the loop is also a great feature, especially in
complex systems when you close the loop with a fibre patchbay.”
OPTOCORE DEVELOPS NETWORK INTERCOM FOR RTS
Munich, March 27th, 2012
New devices provide greater intercom transport flexibility
Following the strategic partnership set up last year with intercom solutions
provider Clear-Com, which saw the launch of the V3R-FX-INTERCOM and X6RFX-
INTERCOM, Optocore has taken a further step towards making the Optocore
system more flexible with intercom transport by developing a similar network
intercom solution for RTS.
The ‘V3R-FX-INTERCOM for RTS’ and ‘X6R-FX-INTERCOM for RTS’ interfaces
are a result of cooperation with the leading intercom manufacturer.
Based on Optocore’s well-known V3R-FX / X6R-FX1U series architecture the
devices are equipped with standard RJ45 interfaces, which make cabling simple
and cost-efficient. As a result of creating an intercom version based on these
converters, the new intercom devices are also Line-In and Line-Out converters.
The V3R-FX-INTERCOM for RTS integrates seamlessly into the Optocore
Optical Digital network system and intercom inputs can be routed to MADI,
AES/EBU or Line outputs, with Intercom messages and control data from RTS
user panels or matrix sent transparently through the optical network. Each single
intercom channel can be routed to every INTERCOM device in the network via
the Optocore Control software.
The V3R-FX-INTERCOM device is equipped with eight RJ45 intercom interfaces
— four ports for panels and four ports for matrix. The pin out of the connectors is
compatible with all RTS devices, so there is no need to use special cables or
adapters — a standard straight CAT5 can be used.
The Word Clock IN and OUT enables the synchronisation of the units to an
external source and is used to pass on the word clock from one unit to the next.
For stand-alone applications, the devices are equipped with an internal word
One V3R-FX-INTERCOM can exchange up to 1024 intercom channels from the
fibre network, 64 intercom channels from the SANE network and eight intercom
channels from the I/O interfaces. The V3R-FX INTERCOM units can be operated
and controlled via the Optocore network with Optocore Control, without the
necessity of any external data cable. For control in stand-alone applications,
USB, RS232 or LAN port on the front / rear panel can be used.
The FPGA (field programmable gate array) based concept of the internal logic
circuitry permits updating of the firmware ensuring a continual state-of-the-art
The X6R-FX-INTERCOM for RTS has similar architecture and features, but with
eight ports (to Panel) and eight ports (to Matrix); one port can be used either to
Panel or to Matrix — though not at the same time (for example Ports 1-4 may be
connected to RTS panels and ports 5-8 to RTS Matrix).
The new V3R/X6R-FX INTERCOM for RTS will begin shipping immediately.
MARC BRUNKE EMBARKS ON DiViNe JOURNEY VIA ROUTE 66
Munich, March 23rd, 2012
Optocore founder’s new start-up focuses on configurable, all-standard
video routing, with Optocore integration.
German digital fibre specialist Marc Brunke has formed a new company, Broadcast
Manufactur GmbH, dedicated to developing its proprietary DiViNe (Digital Video
Network) technology for the broadcast market.
DiViNe is designed to provide routing and repeating, as well as transport and distribution
of multiple professional SDI video signals over fibre-based infrastructures, preconfigured
to customer requirement at the time of order. This is accomplished by WDM
multiplexing/de-multiplexing, enabling multiple distribution through single fibre or COAX
Marc Brunke at PLS 2012, Stand Broaman
The system itself can be constructed from a series of modules, which use DiViNe
building blocks to create a multiple channel distribution system with or without routing.
The devices consist of Route66, Route33, Repeat66, Repeat33 for flexible applications,
and Repeat48 as standalone SDI to fibre converter with or without WDM multiplexers.
The individual devices can be tailored to provide solutions for specific projects with a
requirement to send, receive, multiplex and demultiplex as well as convert professional
video signals, including SD, HD and 3G. The devices can also be interfaced to audio and data network systems, like Optocore,
SANE (Synchronous Audio Network plus Ethernet), MADI and Ethernet.
The new system went into production after Marc Brunke’s design team, which has
traditionally provided optical fibre network solutions for the large-scale events industry,
had been asked to fulfill a request from Studio Hamburg MCI for four independentlyconfigured
automatic routing systems for Sveriges Television (SVT) via a modern, fibrebased
video stagebox concept.
“The ability to do this had not existed previously,” explained Brunke. “We designed for
SVT an auto-router for video, where the stagebox can be connected anywhere and the
central router will always route the channel to the correct position. In addition, we
provide solutions which are entirely cost-optimised.”
All devices offer routing and signal repeating respectively, as well as the ability to
convert the signal from electrical (BNC) to optical (fibre). Every product can be
configured differently to handle up to 66 (or 33 in the half-populated board) 3G video
Each unit can be delivered in 1RU or 2RU housing, depending on the number and type
of BNC SDI and fibre interfaces required. The 2RU frames are equipped with up to 24
SDI ports for SD/HD/3G video and up to 56 simplex LC fibre ports while the 1RU frame
will support up to ten SDI and eight simplex LC fibre ports. SDI ports can be delivered as
inputs with adaptive EQ, inputs with reclocker, outputs with or without reclocker and
selectable I/O. Optocore can also provide black burst sync.
In addition, the internal logic is upgradeable and comprehensive status control is offered
via LED banks on the front. The system can be controlled remotely via external control
platforms (like VSM) or routed automatically.
Route/Repeat 66/33 devices can optionally be equipped with standard Optocore FX
boards, which are taken from their popular R-series devices, to seamless add audio
and/or data routing to the system.
“DiViNe technology presents a unique solution,” states Brunke. “We can route, distribute,
and we can take multiple video and audio channels and put them down a single fibre —
in fact there’s almost nothing we can’t do with this system.”
Since the device is already complete within its own frame (and inherent power supply),
even a large system can be installed inside two hours. The layout is more logical than
other systems on the market, and is more energy- and cost-efficient. It also offers a
higher channel count and more flexibility than competitive models.
DiViNe technology will make its world broadcast debut at NAB Show in Las Vegas.
OPTOCORE AND FIBER DOMINATE THE 54th GRAMMY AWARDS
Munich, February 17th, 2012
On Sunday, February 12, 2012 the 54th Grammy Awards were held at the Staples Center in Los
Angeles, CA to celebrate the industry’s best recording artists and unlike previous years the
technical setup was predominantly based on fiber optic networks with minimal conventional
For the second year in a row ATK Audiotek relied on an Optocore network to
transport the award winning music of Adele, Bruce Springsteen and the E Street Band, The Foo
Fighters, and The Beach Boys, just to name a few of the 21 performances and the 33 separate
Band Coldplay at the 54th Grammy Awards 2012
The complex nature of the Grammys show in conjunction with the ‘mission critical’ delivery aspect
of a live event defines the need for flexibility and absolute fault tolerance and recovery that only
Optocore’s unique 3-way redundant architecture provides. Jeff Peterson, the incumbent System
PA Designer for the award show expanded this year’s fiber optic network drive system to a mere
8 Optocore devices in 4 locations, distributing the primary AES signal and an analogue backup
feed to the processors and amps as well as all the XTA speaker processor’s control data.
The front end of the PA system was comprised of redundant Digico consoles at three mix
locations; 2 desks at FOH (Production and Music Mix), plus a main and backup console at each
of two separate monitor locations.
At FOH, the Optocore network received 3 MADI feeds from the
Digico consoles. The SD 10 Production console provided the main show feed and the prime word
clock sync to one of two Optocore DD4MR-FX dual channel MADI interfaces. The second
DD4MR-FX received two MADI streams from the dual engine SD 7 Music Mix desk along with
redundant word clock thus providing a complete backup feed for the system.
oriented content on the Optocore network was the Network Control data for the Powersoft
amplifiers for the main PA, subs and fill cabinets. Two dual fiber multimode tactical cables ran
from FOH to three node locations under the stage at center, left and right positions.
At the center position were 2 Optocore DD32R-FX AES devices which fed signal and control data
to 10 XTA speaker processors. Peterson’s clever utilization of the DD32’s bi directional AES ports
allowed for the post-processor AES signals to be re-injected into the network for distribution to
stage right and left processors. Three outputs were allocated for front fill speakers and subwoofer
On each side of the stage to feed the main line array amplifiers was an Optocore X6R-FX-16AE
with 16 AES out and a V3R-TP-8LO, 8 line out device which was used to feed auxiliary areas that
required analog signals. TP Series devices have additional independent AES outputs via DB-25
ports that can be configured as either inputs, outputs or an 8/8 I/O configuration, where in this
instance fed more Powersoft amps. The X6R-FX-16AE resided on the network via optical ports
and was connected via it’s additional SANE CAT5 RJ45 ports the V3R-TP-8LO creating a sub
Peterson, a certified Optocore Event Technician was first exposed to Optocore 2 years ago at the
2010 Jerry Lewis Labor Day Telethon for Muscular Dystrophy, where he saw the ease of how
devices can be rapidly deployed, and connected simply with lightweight fiber optic cable, allowing
for long runs and better sound quality than a traditional copper cabling system would yield.
Combined with high channel counts, large matrix capability, and flexible and redundant routing
features, he became an instant advocate as his specialty is high profile live television shows and
major LA based globally broadcast award shows.
When asked, Jeff Peterson said “Optocore made set up effortless. I received the devices on
Friday, a week before the show, Monday morning we set up and I was able to go home Monday
night because the system was up and running and dead quiet due to the fiber network’s optoisolation.”
Peterson added “I was able to seamlessly route signals as needed. With the Macro
feature of Optocore Control, I could instantly switch between main and backup consoles, and reroute
around any failed speaker processor. Fortunately, we never had to use the feature, but I’m
glad it was there.”
OPTOCORE HELPS VANGELIS INAUGURATE DOHA AMPHITHEATRE
Munich, February 15th, 2012
De Préférence provides advanced solution for celebratory work at Katara.
An Optocore system has been used by leading French rental company De Préférence
for a one-off show by Vangelis, to inaugurate the new Katara Amphitheatre in Doha.
The Greek composer had written a celebratory opus for the grand opening and the
Paris-based production company, which specialises in large-scale spectacular events
such as this, was tasked with constructing an optical fibre ring using seven of their
Optocore and SANE converters to deliver the sound to an audience of 3,000 people.
The concert also brought together the Qatar Philharmonic Orchestra (a multinational
ensemble) and Moscow's Yurlov State Academic Choir, boosted by superstar soprano
Angela Gheorghiu and tenorissimo, Roberto Alagna.
Angela Gheorghiu singing at the stage of the new Katara Amphitheatre in Doha
This required De Préférence, and their 14-strong crew, to construct an elaborate
network loop via Optocore fibre and SANE Cat5 Ethernet platforms, using X6R-TP /
X6R-FX converters, capable of handling the main and pre-mixes, including the orchestra
and chorus premixes from the Yamaha DM2000 desk; at the same time Optocore
DD4ME’s were deployed to connect via a MADI bridge to the DiGiCo SD7 FOH desk for
Placed on the network were Yamaha DM2000 digital consoles, one handling the stage
recording premix and one sending a chorus premix to the DiGiCo SD7 FOH and monitor
consoles (for recording). From the DiGiCo environment the digital signal passed through
an Optocore DD4ME Dual MADI network device to the Yamaha DME64 PA processor.
The DD4ME’s interfaced between the DiGiCo SD7 and the Optocore loop (the MADI
1 OUT assigned to the chorus premix between the DM2000 and SD7 consoles, while
Madi1 IN was a copy of the DiGiCo stage rack).
An Optocore DD2FR-FX was used as the MADI interface for recording, with two
multitrack recorders — one for playback connected directly to the FOH DiGiCo SD7 and

OPTOCORE APPOINTS SOUNDWARE
AS DANISH DISTRIBUTOR
Munich, February, 2012
Optocore has appointed Soundware as its new distributor in Denmark.
The Risskov-based company, which represents a portfolio of leading studio, broadcast,
theatre and live pro audio brands, confirms that Optocore will fit perfectly into its
existing roster, alongside DiGiCo, ClearCom, Direct Out and many others.
"Optocore has a first-class pedigree in the distribution of audio, IP Intercom and
video," noted Soundware Pro Audio Manager, Kim Johansen, who had personally encountered
and used Optocore systems over the years, but felt the brand's potential was not being
The German manufacturer also believes it has found the ideal partner.Said International
Sales & Marketing Manager, Mark Davidson, "We chose Soundware due to their knowledge of
the broadcast, fixed install and live performance markets in Denmark as well as their
experience and reputation."
One obvious attraction to Soundware was the fact that Optocore can be integrated with
major brands including DiGICo, Studer, Lawo, ClearCom and Neumann, while SSL, Studer
and DiGiCo desks also control Optocore preamps.
As a result, Kim Johansen said he was relishing the challenge ahead and the exciting
prospect offered by Optocore.
"Although Optocore has long been a leader in fibre optic solutions, by recently extending
its core area to the CAT5 SANE protocol - enabling their devices to be made into an optical
ring while having a small side network running SANE -the possibilities are
"Having high quality products to offer to our clients is a keystone in our business," he
concluded. " We deal directly with rental houses and broadcast facilities which all need and
expect the best. And with brands like Optocore on board we endeavour to provide them with
Soundware already has Optocore demo racks containing DD2FR, DD4MR, X6R-FX and X6R-TP network
interfaces and will be undertaking OCT training in due course.
OPTOCORE boosts functionality for Muscat's World-Class Opera House
Munich, January 31st, 2012
Occupying an eight hectare site, the magnificent new Royal Opera House Muscat (ROHM), built at the
behest of Sultan Qaboos Bin Said, was officially opened in October. The complex, consisting of a concert
theatre, auditorium, formal landscaped gardens, cultural market with retail outlets and luxury restaurants,
is an arts centre for musical, theatrical and operatic productions, and has been designed to reflect
contemporary Omani architecture.
Despite being classified as an Opera House, the main performance space converts from a theatre setting
into a world class concert and organ recital hall.
The technical infrastructure of ROHM has now been further boosted with the delivery of an Optocore
optical fibre network system which will enhance connectivity and route signals to the many different
performance spaces within the complex. At the same time a MADI bridge will enable recording from the
proposed Capture/Production suite whilst using Optocore converters to link with a Midas XL8
front-of-house mixing console.
In proposing the Optocore design, Bruno Silva, one of ROHM's Deputy Sound and Broadcast Managers
(formerly a manager at Kings Place in London), sourced the 20 Optocore components for the network
from long-standing UK Optocore specialists, HD Pro Audio.
He is one of three resident experienced sound engineers, who joined the project in September 2010.
The remainder of the team comprises Head of Sound and Broadcast, Collin Chivers (formerly a manager
at the Royal Opera House Covent Garden) and Joint Deputy Manager of Sound and Broadcast, Mike Compton
(formerly a senior sound engineer at the Royal Shakespeare Company, Stratford upon Avon).
Muscat's World Class Operahouse, frontside
Working with the consultants, they modified some of the specifications, adding additional equipment
including the Optocore network. "We knew this would boost the sound and video comms connectivity via
analogue, optical, video and Ethernet patches," stated Bruno Silva.
In addition to the main configurable auditorium, the Optocore network extends coverage to the smaller
80-seat studio theatre the terrace, on the roof of the building, the front of house foyer spaces and
to the a large outside marbled space ('Maidan').
Bruno adds, "The ROHM is Oman's premier venue for culture and arts, receiving acts from around the
world. Its many performance spaces can host many different events and all will benefit from the
Headroom has been built into the system so that the Pro Tools capture suite, with a proposed Lawo
mc90 desk and video gallery, can eventually be connected to the Optocore network, without the need
for an additional stagebox; the network can also be arranged to provide multi-tracking to OB's.
The newly commissioned Optocore solution provides the house with a flexible input and return system.
At the hub is a DD32R-FX in the main theatre comms room, offering 32 AES ports with SANE and Ethernet.
Providing a much more energy efficient option than its predecessor (the DD32E) the SANE port has
allowed the ROHM team to be highly creative, adding analogue channels, Ethernet and MADI-based CAT5
connectivity to the network.

ports, linked to Klark Teknik DN9650 processors and to the two Midas XL8 FOH consoles via a RME MADI
The two main stage racks offer 48 channels, so that one or both racks can be deployed for the orchestra
or split across other areas of the building.
The racks consist of four further X6R-FX and CAT5-linked X6R-TP modules, (variously configured 16MI and
8MI/8LO), before outputting to a further X6R-TP (16MI) and X6R-FX (8MI/8LO) on the Terrace stage,
connected via an Optocore DD4MR-FX and LX4B FOH network converter, with 48 outputs and 16 inputs at FOH.
Also linked into the digital architecture are the Foyer/Porch, via an additional X6R FX (8MI/8LO),
and three rack modules in the Studio Theatre - comprising X6R-TP's (configured 16MI) and X6R FX (8MI/8LO).
"The whole idea behind Optocore is to enable us to relay audio and record, across the stage areas," says
Bruno Silva. "For instance if we need to put a band into the second theatre we can use the Optocore to
connect the multi-channels to the FOH Midas desk using the local Optocore preamps and to also split the
feeds simultaneously to the Capture suite and Lawo mc90 desk, deploying the MADI stream of the DD2FR-FX
Having Optocore running across the building provides all kinds of possibilities, he says. "We can link
the signals and relay from area to area, using all available pro audio standards including AES/EBU and

and architects WATG, working with the in house interior designers and the client (The Royal Court of
At the same time, one major feat, achieved in conjunction with the consultants Theatre Projects, was the
making of the main stage and auditorium reconfigurable - adjusting the acoustic space to produce a
beautiful sounding seamless concert space.
NORWEST EXTENDS OPTOCORE CAPACITY
FOR PAN ARAB GAMES
Munich, January 15th, 2012
The 12th quadrennial Pan Arab Games took place in Doha, Qatar recently - the first time that
the country had hosted the multi-sport event.
Khalifa International Stadium was the main venue for the competition - as well as the Opening
& Closing Ceremonies, which were attended by around 40,000 people.
Norwest Productions again worked alongside event sound designer Scott Willsallen, fielding a
specialist crew including Ian Shapcott, Steve Caldwell, Trevor Beck and Justin Arthur. Another
familiar presence at the stadium was the giant Optocore fibre ring.
According to Norwest Project Manager, Andrew Marsh, "The designs for these Opening & Closing
Ceremonies almost always use Optocore for the signal distribution. We have a great investment
in the Optocore brand and we hold many of the devices in our rental inventory. Optocore is a
very unique product that has placed itself at the top of the signal distribution pile."
Prior to the event Norwest purchased an additional six of the new X6R-FX network converters
with Ethernet to add to their already considerable Optocore stock. This enabled them to facilitate
the 19 nodes that were required - five of which five collected the bulk of the inputs on the
To achieve the distribution architecture the network was constructed around a mixture of Optocore
DD32-E, DD32R-FX, DD4MR-FX, DD2FR-FX, X6R-FX, X6-16 In, X6-16 Out, X6-8 In/8 Out interfaces -
deployed across the 19 nodes.
Around 5.5km of multimode 4-core tactical fibre was deployed to link all nodes, enabling Norwest
to use the last two cores in the cable to connect Gigabit fibre switches at each node for the purpose
of running an audio LAN.
"All nodes were used to deliver system outputs of some kind," confirmed Marsh, "whether it was PA
system outputs, time code, paging etc."
AES and MADI signals were sent to line array clusters distributed around the stadium. The main
L'Acoustics PA comprised 116 x L'Acoustics Kudo and 36 x SB218 subs with 16 x EAW BH760 subs,
28 x dV Dosc, 8 x dV Sub. The system was powered via 54 x L'Acoustics LA8 amplifiers, 36 x Lab
Gruppen PLM10000Q amplifiers, and mixed through a pair of Digico SD8 digital consoles.
Inputs were split at the source to enter both Optocore and analogue networks at each node and
outputs were fed back from the patch to Norwest's Dolby Lake switching processors, which acted
as switching devices at each node. While Optocore MADI devices were used on the primary system
Digico Digirac's were used on the parallel analogue redundant system.
A pair of Merging Technology Pyramix Mass Core DAW's delivered the show audio to the Optocore
network using MADI splitters and SRC's to enable both the playback machines to feed the Optocore
and back up networks simultaneously.
Each project brings its own set of challenges and in this instance Norwest's main task was to
get the equipment to site and installed in time, within a stadium that presented its own logistical
difficulties. "In general, as people push for increased efficiency, we find that there is less and
less time to install events like this. The beauty of Optocore is that it is fast and incredibly
flexible in these situations plus the new generation of products has a very high I/O capability."
The show theatre itself created a dramatic spectacle and went without a hitch. The cultural section
included a number of performers from the region such as Jordanian performers Nadim Sawalha and Abeer
Issa. There was a solo performance from Egyptian singer Ehab Tawfiq who performed during the pre-show.
During the main ceremony there was performances from Qatari singer Fahad Al Kubaisi and Syrian singer
Andrew Marsh attributed the success of the show to the technical design and implementation of the
distribution system. "We were happy with how our crew and equipment performed and are looking forward
to the next challenge. From our client's point of view, it sounded great and nothing failed … so I
think they are very happy."
