TW121/M11A Wireless microphone

TW121/M11A is a single channel 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. The chassis and hand-held microphone is made of high-grade ABS material, long-term use is not easy to damage. The cartridge is dynamic high-fidelity pickup.
