Stage Announce / Relay Contacts
The stage announce output connector is where the audio exits
the base when any of the beltpacks press the [SA] button. The
output is balanced audio though a male 3-pin XLR. The state
announce output level is set at the factory for 2 Vrms typical
output at rated deviation into 600 Ohms. This should be
adequate for most applications. There is an internal level
adjustment for this output too. See Figure 27 for the location of
the small level trimmer. The top cov
er of th
e base station must
be removed for access.

Relay Output Schematic
A relay contact closure is also activated when a beltpack user
presses the [SA] button. The contacts are normal open (N.O.).
Rating: 1 Amp at 24 volts AC/DC maximum. A Phoenix type
connector (supplied) plugs into the relay contact port on the rear
of the base station. This connector provides a screw-type closure
for an easy connection to wires.
