Stage Announce Audio
The Stage Announce (SA) function in the BaseStation is used to send a Radio Pack’s (RP) microphone
signal to a dedicated external audio output. When a user activates the SA function from an assigned
button on an RP, their microphone is re-routed and is sent to the BaseStation's SA audio output.
Pressing the SA button enables the headset microphone, regardless of the status of the Talk buttons. If
enabled, all RPs can access this feature. If more than one BaseStation is present, SA audio will be
routed out both (or all) of the BaseStations' SA ports simultaneously. The SA audio is identical on all
BaseStations system-wide.
The SA output connector is an XLR-3M. The SA connector is balanced and transformer isolated and
outputs nominal line level audio on a numerical scale from -10 to +10. The default setting for SA Relay is
"Enabled." The default setting for SA Audio is "0."
