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 out-
put is balanced audio though a male 3-pin XLR. The stage an-
nounce 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 23 for the location of the
small level trimmer. The top cover of the base station must be
removed for access.
