KM1 2-Channel UHF Wireless Headset Microphone System

100 UHF frequency points can be selected, antenna diversity anti-jamming operation.
The bodies of all transmitters are made of solid and ergonomic all-aluminum material for a comfortable grip.
With automatic frequency binding function, just press the SET button on the microphone, the transmitter can automatically and accurately lock the working frequency of the receiver immediately.
The stable PLL phase-locked oscillation circuit, combined with the “noise detection” mute control function, can effectively block the computer equipment, karaoke machines, DVDs and other noisy radio frequency interference in the environment.
It adopts the international standard 1/2U metal chassis, with bright LCD liquid crystal display panel.
Battery life is twice that of ordinary microphones.
This series is specially designed for high-end KTV venues. It has the strongest functions and the most stable characteristics, and can obtain the most satisfactory performance in various complex environments.
