Chapter 2: Connecting the Stage Rack
Connecting the Stage Rack to the FOH Rack
The Stage Rack is connected to the FOH Rack via a 75 ohm BNC digital snake. You can purchase a Digital Snake from Digidesign,
or you can purchase one from a cable manufacturer. It is recommended that you use a second, redundant Digital Snake cable con-
nected to Snake 2 ports on each unit. For more information about digital snakes, see“Digital Snake Cables” on page 7.
To connect a Stage Rack to the FOH Rack:
1 Connect the send snake to the Stage 1 Out port of the Stage Rack to the Stage 1 In port on the FOH Rack.
2 Connect the return snake to the Stage 1 Out Port of the FOH Rack to the Stage 1 In port on the Stage Rack.
3 If you are using a second redundant snake, connect it to the Snake 2 ports on each unit in the same manner.
When the FOH Rack and the Stage Rack are powered up, the primary snake connection is indicated by the solid Active LED
(marked “Active”). If the Snake Signal LEDs flash, a Snake connection has not been established.
The connectors on the Digidesign Digital Snake cable are color coded, so that the white connector connects to the white-outlined
ports on the Stage Rack and the FOH Rack.
If you are using a second, redundant digital snake, the primary and the redundant digital snake must be the same length.
If there are problems with the Digital Snake connection, double check that all the BNC connectors are fully secured. If the
problem persists, try reversing the connectors connected to the In and Out ports on one end.

If a second Stage Rack is used, an additional Snake Card must be installed in the FOH Rack. See the Snake Card Guide
for more information.
