The standard DiGiRack has 7 input card slots and 7 output card slots. Each card has 8 sockets and therefore a fully loaded rack has 56 inputs and 56 outputs. Bidirectional cards (AES,and Ethersound) provide 8 inputs and 8 outputs per card. They are installed in the DiGiRack’s input slots and the same numbered output slot must be left empty. The DiGiRack also has 2 hot swappable Power supplies. For extremely long distances, an optics option is available which includes fibercast and ST connections. As standard, there are 2 MADI ports allowing for digital splits for recording or rack sharing between two consoles. Each output slot can be programmed from the rack to provide a post pre amp feed from the analogue inputs. A wordclock input is also provided giving the ability for an entire DiGiCo system to sync to this wordclock input.
