1. Introduction
Module Slots and Rear Connectors
There are five types of backplanes, each featuring a unique set of connectors, as shown in Figure 1-
6. The type of signal being received or distributed determines the backplane used. For each back-
plane installed a corresponding input card or output card must also be installed. For example, if a
backplane is installed to receive AES unbalanced signals, then the input card for AES unbalanced
signals must be installed in the corresponding card slot. (See
Input Cards on page 20.)
Figure 1-6. NV7512 Backplanes
Backplane connectors are labeled with numbers that correspond to the number assigned the signal
passing through the connector. Signal numbers are used when creating switching configurations
(see
Switching Configurations on page 7). For example, on the ‘AES Unbalanced’ backplane, each
connector is labeled ‘1’, ‘2’ and so on up to ‘32’. The signal passing through connector ‘1’ is routed
as signal number 1, the signal passing through connector ‘2’ is routed as signal number 2, and so
on. For a list of all backplane types, connectors and signals managed, see
Backplane Types and Sig-
nals on page 14. For information on making connections between backplanes and signal sources or
destinations, see Making Signal Connections on page 44.
Quad Mix Backplane
Unlike other backplanes, the Quad Mix backplane features three different types of connectors on a
single backplane. Four BNC connectors distribute up to four AES unbalanced audio outputs. A sin-
gle DB25 connection can distribute up to 8 stereo or 16 mono analog audio outputs. An additional
Ethernet connection provides a connection to the Quad Mix control panel (NV9660). The NV9660
