ComPack Telecom / Intercom Link
ComPack also functions as a simple “no-frills” telecom link for your
beltpack intercom system. ComPack will provide bi-directional au-
dio on pin 3 of the male XLR jack to any industry standard intercom
beltpack system. ComPack does not provide power over this XLR
jack nor does it require power from the loop. ComPack will not rec-
ognize a “call” signal generated by your intercom system and it will
not provide one.
1. Slide the Male XLR selector switch to the Com Link position.
This recessed switch is located near the power jack. Accessing
the switch can be done using a small blade screwdriver, or other
such object, inserted into the opening. The left position (towards
the XLR jacks) designates Line Output. The right position
(towards the volume controls) designates Com Link. The factory
default position of this switch is Line Output.
2. Connect your beltpack intercom XLR cable to the ComPack
Com Link Male XLR jack. The XLR jack is wired as:
Pin 1 = Ground
Pin 2 = Com in
Pin 3 = Com out
3. Your intercom headset should remain plugged in to your belt-
pack system, not directly into ComPack.
