Feature：

1.Adopt UHF ultra-high frequency band, DPLL digital phase-locked loop multi-channel frequency synthesis technology.

2. Brand-new audio circuit structure, delicate treble, strong mid and low frequencies, Especially with perfect expressiveness in the details of the sound. The super dynamic tracking ability makes the long/close distance pickup and playback freely.

3. The brand-new concept of digital pilot technology completely solves the phenomenon of cross frequency in KTV private rooms, and never cross frequency!

4. The maximum output volume can be freely limited, and the application range is wider.

5. The receiver can flexibly set the using times.

6. 100×2 channels, and the channel spacing is 250KHz.

7. Super heterodyne secondary frequency conversion design, with extremely high receiving sensitivity.

8. The radio frequency part adopts multi-stage high-performance dielectric filters with excellent anti-interference ability.

9. The first intermediate frequency adopts SAW filter, and the second intermediate frequency adopts three-stage ceramic filter, which greatly improves the resistance.

Interference ability.

10. The specially designed mute circuit completely eliminates the impact noise of microphone opening and closing.

11. The microphone uses AA battery charged by Nanfu, which lasts for 6-10 hours.

12. The microphone adopts a unique boost design, the battery power drop does not affect the overall performance of the hand microphone.

13. The ideal environment has an operating radius of 80 meters, which is suitable for various occasions.

14. The default configuration is an aluminum alloy microphone tube with blue backlight of the LCD screen.

15. With adjustable transmit power and adjustable squelch threshold, an external squelch control knob is set on the rear panel of the receiver, which can beThe effective operating radius can be flexibly set between 10 meters and 80 meters as required.

16. The handheld, lavalier, gooseneck conference seat, and head-mounted transmitter can be combined at will;

17. With infrared automatic frequency matching function, the microphone can be quickly synchronized to the working channel of the receiver.

18. KTV engineering special model, two microphones, one host. Easily configure more than 100 KTV private rooms, (stagger the frequency, Party A provides drawings) unique product structure design, fast and simple maintenance.
