Analog Signals and Signal Numbers
The router frame slots have printed labels that list signal numbers corresponding to AES synchro-
nous stereo signals, numbers 1 through 32. This numbering scheme does not correspond to analog
signals.
For AES stereo signals, 32 signals can be supported, matching the labeling for signal numbers on
the router frame. For analog signals, only 16 analog stereo signals are supported, so signals do not
match the 32 signal number labels. The stereo signal is received through input 1, then input 3, then
input 5, and so on, up to 32, skipping every other signal label number in sequence. However, 32
mono signals can be received, matching the router label number scheme.
When routing mono and analog signals, it is recommended that a labeling convention be adopted
and rigorously followed for all mono switching configurations.
Rear Connections
The rear of the NV7512 (Figure 1-5 on page 12) features a back plate containing backplanes for
receiving and distributing signals. Each backplane contains passive connectors that pass the signals
through to active, receiving connections on the input cards and output cards.
An additional backplane, located in the left-hand section of the upper bay, contains four BNC con-
nectors for the monitor card. In the left-hand region and lower, left-hand corner of the frame are
