The MADI HD card is plugged into the HD card slot in the Stagebox and provides the link to the Local Rack frame. The two interfaces offer up to 64 audio channels with 48kHz operation, together with embedded control and user-accessible serial connection in each direction.

The auxiliary interface can be used as a redundant link.
In slave mode, the card extracts the system clock from the incoming MADI signals and provides it to the entire remote I/O box. It detects all other I/O cards that are inserted into the Stagebox and displays their presence on
the front panel of the frame. Once all audio interface cards are plugged in, pressing the RECONFIG key on the front panel confi rms the confi guration to the system. Then all cards are activated and their audio signals are fed into the MADI link.
