The ProCo Panic Button Microphone A/B and Muting Switch is an active microphone signal routing device that offers clean reliable performance with any balanced or floating low-impedance (150 ohm nominal) microphone or signal source. The foot-operated pedal allows a singer or speaker to reroute the microphone signal from Output A to Output B. The Panic Button may also be set to operate as a momentary push-to-talk, momentary push-to-mute, or latching microphone muting switch. The Panic Button is ideally suited for praise ministers, speakers and professional instrumentalists who need to communicate with their roadies (especially singing drummers and guitarists).
