INSTALLATION
INTERCOM LINE CONNECTION
The PS-702 provides three rear-panel 3-pin male XLR connectors for each
intercom line. These connectors are wired in parallel and intended for
loop-through connection. Any single-channel station or channel of a
multi-channel station connected on a line plugged into Channel A of the
PS-702 will be “party-lined” with all the other stations on that same channel.
In a multi-channel system, the goal is to assign specific people to the correct
group, (i.e., the other people with whom they need to be in contact the most).
This is particularly important when party-line users are on a single-channel
beltpack or station; less so if they are on multi-channel stations. The pinout of
the intercom connectors is as follows:
Pin 1 --- Ground (shield)
Pin 2 --- Power
Pin 3 --- Audio
