Audio Mute Switch
The QT-5100 RefMicHD incorporates a large, easy-use, rocker-style, audio mute switch. This enables the wearer to mute and unmute the audio without causing any audible popping. The mute switch is surrounded by a protective fence that prevents unintentional tripping of the switch by bumping the transmitter. There is a highly visible LED indicator light for mute/live. This transmitter is ideal for Referees, Umpires and a variety of officials who only need audio for brief announcements.
Rugged Protective Mic Connector Shield
The QT-5100 RefMicHD has its Lemo mic connector located on the edge of the transmitter case and protected by a rugged shielding cap that covers the entire connector to prevent damage if the event the transmitter takes a direct hit in use. The protective cap is held in place by a screw, so also prevents the wearer from disconnecting the mic.
Remote Control Audio System
The QT-5100 RefMicHD utilizes 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, companding mode and grouping, all wirelessly.
3000 Channels
The QT-5100 RefMicHD is offered in 3 tuning blocks that span 470 to 700 MHz in 25 kHz steps, with approximately 3000 channels per block.
Comfortable and Concealable
The QT-5100 RefMicHD has a tough nylon case with belt clip. Weighing just over 2 ounces and only 3/4 of an inch thick, the QT-5100 RefMicHD is rugged, unobtrusive and very easy to use.
