Connecting a Second Stage Rack
Before connecting a second stage rack to a D-Show system, a second Snake card (purchased separately) must first be installed in
the FOH Rack.
To connect a second Stage Rack:
1
Install a second Snake card in the FOH Rack. See the documentation that came with the Snake card.
2
Using a BNC cable (included with the additional Snake card), connect the Word Clock Out port on the first Snake card to the
Word Clock In port on the second Snake card.
3
Connect the second Stage Rack to the FOH Rack with a Digital Snake cable. See “Connecting the Stage Rack to the FOH Rack”
on page 12.

The redundant Digital Snake must be the same length as the primary Digital Snake for each Stage Rack.
