This handy, foot-switchable box allows users of in-ear monitors to turn off the microphone signal to the front of house PA system and communicate privately with other band members or the monitor engineer through a second output. 

It also has many other possible uses for temporarily muting or switching a mic signal. The foot switch can be silently operated in several modes, with either momentary or alternate (push on, push off) action, by configuring the internal mode selection dip switches. It can be used with both dynamic and condenser mics.
