A20 true diversity one to two wireless microphone
Performance Series
This is an A20 series true diversity one to two wireless microphone, which adopts advanced wireless transmission technology of true diversity. It simultaneously receives signals through two independent receiving antennas, thereby improving signal stability and reliability. Effectively reduce interference in wireless signal transmission, ensuring clear and pure sound quality. It also has a high brightness LCD display, clear and comprehensive working status, a noise control system, and is easy to
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 LCD display can display multiple functions such as automatic signal selection, frequency point, frequency, transmitter battery level, and receiver 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
