Functional features:

1. UHF ultra-high frequency band is adopted, which has less interference and more reliable transmission than the traditional VHF band;

2. PLL digital phase-locked loop multi-channel frequency synthesis technology provides up to 200 channel choices at 250kHz channel intervals within the frequency range of 50MHz, which is convenient for multiple sets of machines to use at the same time and easily avoid all kinds of interference;

3. Advanced automatic frequency matching technology, even if the frequencies of the transmitter and receiver are disordered, the transmitter will automatically track and lock the frequency and adjust it in line with one click, which is convenient to use;

4. The high-grade LCD screen makes the working state of the receiver and transmitter clear at a glance;

5. The wireless conference transmitting system is powered by three AA batteries, which can be used for a long time (high power 10 hours, low power 14 hours). If a rechargeable battery is used, the service time will decrease.

6. The maximum use range of the open space is more than 100m, and the ideal use range of the open space is 60m.
