Panic Button was designed for live entertainers on stage to switch their microphone signal from Output A (Front of House normal operation) to Output B so they can contact their personal roadie or monitor mixer with emergency calls for help (broken string, dead battery, spilled drink).

Channel B can act as a Cough Drop although the roadie or monitor mixer can hear the cough. Also, phantom power from the FOH mixer powers both channels when condenser microphones are being used, and there is no pop switching between channels.

If the battery in the Panic Button dies, the circuit automatically reverts to Channel A.
