Priority Muting
Follow this procedure to allow the microphone’s push-to-talk switch to mute the background music or other input signals.
On the back of the AA35G or AA60G:
1. Turn DIP switch 2 “Off” Turn DIP switch 3 “On”.
2. Connect a push-to-talk mic contact to the Priority Connector (Figure 3.1). Input 1 is the priority input for the amplified output, so Input
1 mutes the other inputs.
Voice-Activated (VOX) Muting
Follow this procedure to allow a voice to mute the background music or other input signals.
On the back of the AA35G or AA60G:
1. Turn DIP switch 4 “On” Turn DIP switches 2 and 3 “Off”.
2. Talk into the microphone. Adjust the VOX threshold potentiometer on the back of the unit to set how loud the voice must be before
muting occurs. It can be set for no muting.
Zone 2 Output
On the back of the unit, adjust Zone 2 Level Control to obtain the desired noise level.
