* Using UHF ultra-high frequency double true diversity reception, and USES the DPLL multichannel digital phase-locked loop frequency synthesis technology. * Provides each of 200 a total of 600 channels to choose, true diversity receiving, effectively avoiding the phenomenon of fault frequency and to extend the receiving distance. * With a magnitude 8, according to 8 audio level display, according to the audio level, according to the channel menu mute. * Balanced and unbalanced output port, two choices to meet the needs of different device to connect. * LCD liquid crystal display can also showed channel number and working frequency. Light touch button control is simple, which let users to use it more conveniently. * Strong anti-interference ability, can effectively restrain noise caused by th external interference and same frequency interference. * Infrared frequency function, can be convenient, shortcut of the transmitter and receiver synchronization. * Enough intermediate frequency, Relaxed singing, sounds with magnetic and mixed thick feeling, the essence of the vocal microphone sound.
