Stage Announce / Relay Contacts

The stage announce output connector is where 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 stage announce output level is set at the factory for 2 Vrms typical output at rated deviation into 600 Ohms. This should be ade- quate for most applications. There is an internal level adjust- ment for this output too. See Figure 26 for the location of the small level trimmer. The top cover of the 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.
