Brought to you by Gem Sound, the GMW-4 Quad-Channel Wireless Mic System EF offers high-fidelity audio transmission and reception over long ranges. This four-channel VHF wireless microphone system features a super heterodyne receiver and transmitters with 100′ operating range—ideal for karaoke performances, presentations, and events.

Crystal-Clear Audio Over Long Distances

With a super heterodyne receiver and VHF high-band operation, the GMW-4 provides interference-free transmission and studio-quality sound over its 100′ range. Four included handheld dynamic microphones offer warm and articulate vocal reproduction for singing or speaking. Users can operate all four microphones simultaneously without crosstalk or signal degradation.

Reliable, Long-Lasting Power

Each GMW-4 microphone operates for up to eight hours on two AA batteries, providing dependable power for even the longest presentations or karaoke sessions. The receiver connects to any standard AC power outlet for continuous use. With a rugged metal housing, the GMW-4 system is built to withstand the rigors of frequent transport and handling.

Simple Setup and Operation

The GMW-4 Quad-Channel Wireless Mic System EF requires minimal setup. Users simply connect the included receiver to a mixer or amplifier, turn on the power, and match the microphone transmitters to the correct receiver channels. Independent volume control for each channel allows for quick and precise level adjustments. An LED indicator on each microphone shows battery status and transmission signal strength for confidence during use.

Frequency Agility and Licensing Info

The GMW-4 system provides two selectable frequency sets—ABCD and EFGH—to avoid interference from other devices. While most casual users do not require an operating license, the GMW-4 must be operated at low power according to FCC regulations.
