What it is

The UHF-6100M and UHF-6200M are handheld wireless microphone systems with a cardioid pickup pattern, a receiver with LCD readouts for group, channel and RF/AF levels, and 256 selectable UHF frequencies with one-touch SYNC pairing. The 6100M is a single-channel system with one handheld transmitter, and the 6200M is a dual-channel system with two unidirectional handheld dynamic transmitters, a rack-mountable receiver and a compression circuit. The UHF-6100HL and UHF-6200HL are the hands-free counterparts, with a belt pack that carries lightweight headset and lavalier microphones. Per retailer listings, the 6100HL is a single-channel system and the 6200HL is a two-channel system with two headset/lavalier mics; the channel count of the 6100HL is in conflict across sources. The sources do not give a history or production dates for these models. Specifications below are as published by Gemini and retailers and have not been independently measured.

How it's used

Gemini and retailers describe the systems for vocalists, DJs, karaoke, public speaking, worship and presenting. The handheld models are described for duets, interviews, panels and karaoke, and the headset/lavalier models for hands-free use. Listings name bars, clubs, auditoriums and places of worship as settings. The handhelds are used as the microphone in the signal chain, and the receiver output feeds a mixer or amplifier input.

Suggested usage

Pairing
Use the SYNC button to pair each transmitter with its receiver.
Frequency selection
In a busy RF environment, such as a venue with other wireless gear running, use the 256 selectable frequencies to find a clear channel.
Monitoring
Check the group, channel and RF/AF level readings on the receiver display during use.
Gain balance
One reviewer found the wireless mic quieter than wired mics in the same mix and suggested comparing levels during a sound check.
Mixer connection
Set the MIC/LINE switch on the HL models to match the mixer input you are using.
Packing
One owner noted the antenna must be disconnected before the receiver fits back in the box.
