Audio Mute Switch

The QT-5100 RefMic incorporates a non-popping, audio mute switch. This enables the wearer to mute and unmute the audio without causing any audible popping. This transmitter is ideal for Referees, Umpires and a variety of officials who only need audio for brief announcements. This is also a good solution for corporate presenters who need a top quality audio experience that they can control.

The QT-5100 Series utilizes the RCAS™ (Remote Control Audio System) a revolutionary way to remotely control transmitter settings from a central computer or hand held remote control. The remote functions allow technicians to control; on/off, monitor status and battery level and make on-the-fly adjustments of frequency, mic gain, RF power level, mode and grouping, all wirelessly.
