DiGiRack / SD Rack
All connections should be made before switching on the console and racks.
The console and rack each have dual redundant power supplies and both should be switched on at all times. After switching on
the console the software will be launched automatically and the state of the worksurface and settings should be the same as
when it was last Shut Down.
To Shut Down the console press the System>Shut Down button and wait until you receive a message saying that it is safe to
switch the power off.
The SD7 worksurface has 12 analogue I/O and 12 AES I/O on its rear panel (referred to as Local I/O) and additional I/O is supplied
in the form of remote Racks which can each accommodate up to 56 inputs and 56 outputs in different formats. These racks are
connected to the worksurface by either 100M high specification 75 Ohm coaxial cables fitted with BNC connectors or optical fibre.
The Racks have two pairs of MADI connectors - Main MADI IN & OUT and AUX MADI IN & OUT.
In normal operation the MADI connections should be as follows (see diagram above):
Rack MAIN MADI IN connected to the console MADI 1A OUT
Rack MAIN MADI OUT connected to the console MADI 1A IN
Note - Optionally, a second set of MADI cables can be connected to provide MADI redundancy from the
rack's AUX MADI ports to the console's MADI 1B ports
The console's other MADI Ports can be connected to a MADI recorder (See Audio I/O Panel for setup details) or a second DiGiCo
Rack or console.
