Overview DD4MR-FX:

DIGITAL I/O MODULE – The DD4MR-FX is designed to function as a digital interface, wherever MADI ports are required in an OPTOCORE OPTICAL or CAT5 SANE DIGITAL NETWORK SYSTEM. The 4 BNC MADI connectors feature the unique possibility of connecting different MADI input or output devices. With the other Optocore and SANE devices, the DD4MR-FX offers a great flexibility to build the network exactly suiting an application's need. The DD4MR-FX is a perfect interface for Avid or DiGiCo digital console. These common installation interfaces provide a simple and cost-efficient connection to other audio equipment.
