Model:U-650/2 Li Telsiz Mikrofon
Feature:U-650/2 is a dual channels UHF digital wireless microphone. The device uses a revolutionary new technology in wireless microphone technology. Frequency modulation on transmitter, frequency matches on receiver automatically. 40 frequencies in each channel, effectively solve the problem of strong frequency and strong signal interference. Small size metal receiver, coloring and drawing aluminum alloy panel. The hand-held microphone housing uses zinc alloy and high-grade ABS material, it is not easy to damage. The cartridge is dynamic high-fidelity pickup.
