DIGITAL I/O MODULE-The DD32R-FX is designed to function as a digital interface,wherever AES/EBU ports are required in an OPTOCORE OPTICAL or CAT5 SANE DIGITAL NETWORK SYSTEM.The 32 principle ports feature the unique possibility of any combination of AES/EBU inputs and/or outputs.With the other Optocore and SANE devices,the DD32R-FX offers a great flexibility to build the network exactly suiting an application's need. With Optocore microphone preamps (X6R),the DD32R-FX enables the gain control of the preamps on stage from a Yamaha digital console at FOH.These common installation interfaces provide a simple and cost-efficient connection to other audio equipment.
