Features:
1. The patented technology of automatic human hand sensing automatically silences the microphone within 3 seconds after it leaves the hand and is stationary (can be placed in any direction or angle), and automatically enters standby mode after 5 minutes to save energy. The microphone has a floor to ground mute function It is a new concept of intelligent and automated wireless microphone,
2. A brand new audio circuit architecture, with delicate high notes and strong mid to low frequencies, especially in terms of sound details with perfect expressiveness. The super strong dynamic tracking ability allows for easy pickup and playback at both long and short distances;
3. A brand new concept of digital pilot technology that completely solves the problem of KTV rooms crossing frequencies, never crossing frequencies!
4. Equipped with a howling suppression function circuit for easier debugging;
5. Automatic search for interference free channels, making installation more convenient; The host can flexibly set the usage frequency;
6. UHF frequency band, phase-locked loop (PLL) frequency synthesis;
7. 100 x 2 channels, with a channel spacing of 250KHz; Ultra heterodyne secondary frequency conversion design, with extremely high receiving sensitivity;
8. The RF part adopts multi-stage high-performance dielectric filters with excellent anti-interference ability;
9. The first intermediate frequency adopts a sound table filter, and the second intermediate frequency adopts a three-stage ceramic filter, which greatly improves the anti-interference ability;
10. Specially designed mute circuit, completely eliminating the impact noise of microphone on and off;
11. The microphone uses an Easybuy No.5 battery, which can last for 6-10 hours;
12. The microphone adopts a unique boost design, and the decrease in battery power does not affect the overall performance of the handheld microphone;
13. The ideal operating radius is up to 80 meters, suitable for various requirements; The default configuration is a microphone tube with a yellow backlight on the LCD screen and an aluminum alloy body;
14. Equipped with infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver;
15. KTV project specific model, two microphones, one host. Easy configuration of over 100 KTV rooms, unique product structure design, fast and easy maintenance.
