Single Base Station Audiocom (Telex) System
The audio out RCA jack on the back of this unit is
used for the public address system. The unused
Audiocom channel must be terminated to avoid
loud feedback if audio channel two was switched to
by the beltpack.
The audio out of the base station’s RCA jack is the
audio channel currently switched to at the BTR-500.
