1. UHF ultra-high frequency band, digital pilot technology;
2.DPLL digital phase-locked loop multi-channel frequency synthesis technology, ≤50MHz frequency bandwidth, 250KHz channel interval, to provide up to 200 channel choices, easy to use multiple sets of machines at the same time, easy to avoid all kinds of interference
3. Advanced automatic frequency technology, even if the frequency of the transmitter and receiver is messed up, you just need to click, the transmitter will automatically chase the receiver frequency and adjust the same, easy to use
4. Special high-low power switching function, so that you not only in gatherings and other activity places (high-power transmission), the use of smooth, but also in such as school classrooms, KTV room use (low-power transmission), save battery power;
5. The special receiving sensitivity adjustment function can adjust the sensitivity according to the need to improve the anti-interference ability or increase the receiving distance;
6. Intelligent 3-second induction switch, full of science and technology;
7. Automatic search without interference frequency point function;
8. One key frequency lock or two SET keys at the same time frequency lock function, to prevent misoperation during use;
9. Password lock function, limit the use of boot times;
10. Electronic volume control, adjustable range 0-39 per step 2dBm;
11. One-key installation mode, with 100 groups of installation frequency points, easy to use multiple sets of frequency points at the same time;
12. There are 4 preset balance modes (1) flat, (2) increased bass, (3) high cut, (4) increased bass simultaneously high cut;
