Product Features:


1. Adopting a pure automatic selective (true diversity) receiving method, with four independent antennas for reception and a microphone for long-distance reception;


2. Adopting high-end imported microphone cores, the sound quality is broad and beautiful;


3. The handheld microphone style is classic, with adjustable high and low power switches and a mute function switch.


4. The receiver is equipped with automatic search for clean frequencies, a self set panel function lock for safe use, and independent 200 adjustable channels for the receiver channel;


5. The receiver's LED LCD display can display multiple functions such as automatic signal selection, frequency point, frequency, transmitter battery level, and receiving sensitivity; The standby state is displayed in orange, while the usage state is displayed in white.


6. Using a unique CPU to control the power on/off, there is no impact sound when the transmitter or receiver is in any state;


7. Adopting professional secondary frequency conversion and multi-stage RF filtering technology, multiple sets of use do not interfere with each other, and triple static noise detection of audio code, RF intensity, and noise eliminates interference;


8. Equipped with long-distance power regulation;


Applicable scenarios: outdoor performances, multifunctional halls, luxury entertainment KTV rooms, conference rooms in enterprises and institutions
