The DiGiCo D-Rack comes as standard in the SD9 system and is available as an option on all SD-Series consoles. The D-Rack provides 32 microphone inputs, 8 line outputs and 8 modular outputs that can be selected as either analogue or AES, providing a maximum capacity of 32 inputs and 16 outputs. With a digital CAT5E cable to connect to the console work surface, the hum and noise of analogue multicores are eliminated. It can now also run at 96kHz on CAT5E with 28 Mic inputs and up to 16 outputs. The D-Rack also offers the options of Rack mount ears, an extra PSU (for redundancy) and fiber optic connection.
