Functional characteristics
1. Adopt true diversity reception, double reception digital pilot technology;
2. Automatic search without interference frequency point function;
3.DPLL digital phase-locked loop multi-channel frequency synthesis technology, ≤50MHz frequency bandwidth, 250KHz channel interval, providing up to 200 channel choices;
4. Automatic frequency matching, using the most stable characteristics of phase-locked loop synthesis tuner (PLL), can effectively block noisy RF interference in the environment.
5. Special high-low power switching function;
6. The special receiving sensitivity adjustment function can adjust the sensitivity according to needs to improve anti-interference ability or increase the receiving distance;
7. One-key frequency lock to prevent misoperation during use;
8. Electronic volume control, adjustable range 0-39 per step 2dBm;
9. One-key installation mode, with 100 sets of installation frequency points, easy to use multiple sets of frequency points at the same time;
