Whirlwind MIC MUTE PP Microphone Mute Floor Pedal Switch Control Box The Micmute PP is configured as latching Push On; Push Off switches, meaning that the switch must be pushed and released to turn the signal on or off through the box. Each time the switch is pressed and released (PP) the signal is changed from one condition to the other. The PP has an indicator LED feature that is operational when the connected microphone preamp input is providing phantom power.
