Features：

1、Intelligent wireless microphone，the microphone is automatically muted within 3 seconds after it leaves the hand stationary (any direction and any angle can be). Automatically save energy and enter standby mode after 5 minutes. Automatically shut down after 15 minutes and cut off the power completely. Is a new concept of intelligent and automated wireless microphone.

2、Brand-new audio circuit structure, delicate treble, strong mid/low frequency，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, never cross frequency！

4、The output volume can be freely set, the range of adaptation is wider.

5、The receiver can flexibly set the using times.

6、UHF frequency，Phase locked loop(PLL) frequency synthesis。

7、100×2 channels，channel spacing 250KHz。

8、Super heterodyne secondary conversion design, with extremely high receiving sensitivity.

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

10、The first intermediate frequency uses a SAW filter, and the second intermediate frequency uses a three-stage ceramic filter, which greatly improves the anti-interference ability.

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

12、The microphone uses Nanfu's AA battery, which lasts for 6-10 hours.

13、The microphone uses a unique boost design, the battery power drop does not affect the overall performance of the handheld microphone.

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

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

16、With adjustable transmit power and adjustable squelch threshold，An external squelch control knob is set on the rear panel of the receiver，The effective operating radius can be flexibly set between 10 meters and 80 meters as needed.

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

18、KTV installed special model, two microphones, one receiver。Easily configure more than 100 KTV rooms，The product structure is unique in design and maintenance is quick and easy.
