INSTALLATION
Choose the location of the PS-704. The unit requires access to AC power. It
should be located away from other equipment that generates excessive
amounts of heat. The choice of location will also depend upon the wiring
scheme (refer to the section “Wiring”).
INTERCOM LINE CONNECTION
The PS-704 provides two 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-704 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 the 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
