With UHF PLL circuit and sound code and noise lock mute control, it can not only receive a long distance, but also eliminate the loss of broken sound and unstable reception, so as to prevent the interference of radiation noise such as song player, computer and DVD drive
◇ with the world's first IR automatic channel tracking key, as long as you press it, you can immediately make the transmitter automatically and accurately lock the working channel of the receiver, without any error or fault.
◇ 1U metal case built-in dual channel receiving module, with strong, heat-resistant and professional quality of harmonic radiation interference isolation.
◇ it has the function of automatically searching for undisturbed channels. As soon as you press up / down, the receiver will automatically scan the preset 200 groups of undisturbed frequencies and lock the undisturbed working channels.
◇ this model is the most easy to use, the most powerful and the most stable luxury model. It can get the most satisfactory results in various complex professional singing environments.
◇ it has many patents, passed many national radio regulations and safety regulations certification.
