Partyline: How do I wire a audio program input to RS-702 beltpack?
The RS-702 Encore Series Beltpacks are capable of accepting a balanced line level program audio feed.
This is accomplished by using pins 5 and 6 of the 6-pin XLR intercom feed. The ground for the program audio feed is brought in on pin 1.
The thumb wheel control on the bottom pane of the RS-702 Beltpack only attenuates the signal received on Pins 5 & 6 of the XLR-6 connector.
It will NOT attenuate the program audio (signal embedded and sent through with the intercom audio signal of CH A/B) if the signal is sent through from the Mainstations.
Please see the diagram below for the locations of the pins.
