Figures 26: Model 322 Intercom Locations
Intercoms can be of any type in any location in the assembly. However, for proper operation of
the intercom channel, the same placement order must be followed at any other assembly at the
other side of the system.
A 2-wire system can be interconnected with a 4-wire system at another Adder 162/322, but not
all intercom functions will work (for example, calling).
If an optical split output is used to connect fiber to additional receiving locations, the intercom
signals will be present at the receiver, but transmission back to the originating unit will not be
possible.
4-wire Auxiliary (balanced) intercoms use an individual 5-pin XLR on each of the two channels
in each module. Refer to Figure 27. XLR pin functions are given in Table 7. Intercom Module
Gain is 0 dB.
50 dB of gain may be added to 4-wire module inputs by DIP switches on the mother
board for MIC applications. See Intercom Setup Switches on page 26.
