Quad Mix
Using the Quad Mix output card, the NV7512 can route both AES synchronous unbalanced signals
and analog signals through a single backplane. (See
on page 28.) The Quad Mix output
card and Quad Mix backplane can be used in place of any other output card and related backplane.
AES synchronous unbalanced signals are distributed through four BNC connections, labeled ‘1’,
‘2’, ‘3’, and ‘4’ and one DB25 connector (not labeled) for analog signals. The coaxial connections
are housed on the Quad Mix backplane installed in the back plate. (See
The Quad Mix backplane also features a connection to the Quad Mix control panel, NV9660. The
NV9660 is required to manage the Quad Mix output card functions. For more information on the
NV9660 control panel, see
NVISION’s NV9660 Quad Mix Control Panel
How to make Quad Mix connections
1 Locate the Quad Mix output connections at the rear of the router, as shown in Figure 2-13. Out-
puts are located in the upper half of the router frame. The exact location of the backplanes and
corresponding connectors may be different depending on your router configuration.

2 For AES unbalanced signals, use a 75
Ω BNC connector and coaxial cable.
3 Connect the other end of the cable to the signal destination.
