The Wirlwind Micmute PT and PTD are configured as Push to Talk switches, meaning that the input signal is normally not connected to the output; nothing is passing through the box. When the switch is depressed and held down, the signal is turned on and passed through to the output. The signal is disconnected as soon as the switch is released.
The Whirlwind Micmute boxes offer passive switching solutions for controlling the on and off conditions of a microphone or balanced line signal via footswitch or finger switch operation.
There are three styles, which cover all the essential mic control functions. Each style of Micmute is available with two types of actuator; a heavy duty footswitch (models PT, PM, PP) and a finger operated version for desktop use (models PTD, PMD, PPD).
Each box has a female XLR input and a male XLR output jack. When no signal is passing through the boxes, the output jack is configured to mute the input of the connected audio device.
All three styles of MicMute will pass phantom power for use with condenser type microphones.
