Expanded Audio System Monitoring

Expanded Audio systems require external looped cables between the two
frames for monitoring. You need to connect a cable from a

Monitor Out

con-

nector on a backplane in the base frame to a

Monitor In

connector on a back-

plane in the expansion frame. And a second cable from the

Monitor Out

connector on the same backplane on the expansion frame to the

Monitor In

connector on the backplane in the base frame. You can use any of the avail-
able connector types and any of the available backplanes.

Figure 53

shows

an expanded 256x256 system, using the terminal block connectors on the
backplanes in slots 1 and 5. The connectors could be used on any of the
backplanes. Since all of Outputs are available to all of the monitor connec-
tors on each frame, it does not matter which two backplanes are used; as
long as it is one in the base frame and one in the expansion frame. In

Figure 53

the recommended cabling is shown.

One Destination signal is available to all of the

Monitor Out

connectors in the

configured matrix. All the backplanes have at least one

Monitor Out

con-

nector. Two of the AES Audio backplanes have two

Monitor

Out

connectors.

On the AES Terminal Block backplane there is a terminal block

Monitor Out

connector and a BNC

Monitor Out

connector and on the AES 50 pin D back-

plane there is a 9 pin D

Monitor Out

connector and a BNC

Monitor Out

con-

nector. See

Table 39 on page 93

for the 9 pin D connector pinouts used on

the 50 pin D backplanes. See

Figure 47 on page 95

for the terminal block

connector pinouts used on the terminal block backplanes. For more infor-
mation on configured matrix sizes and number of Mon Out connectors per
matrix see
