Features
- The patented technology of automatic 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). After 5 minutes, it automatically saves energy and enters standby mode Machine status, microphone floor to ceiling mute function It is a new concept of intelligent and automated wireless microphone,The brand new audio circuit architecture features delicate high frequencies, strong mid to low frequencies, and powerful dynamic tracking capabilities, allowing for easy pickup and playback at both long and short distances;
- The new concept of digital pilot technology completely solves the problem of frequency crosstalk between KTV rooms.
- Equipped with a howling suppression function circuit, debugging is easier;
- Automatic search for interference free channels, making installation more convenient;
- Automatic selective true diversity reception, UHF frequency band, phase-locked loop (PLL) frequency synthesis:
- 100x2 channels, with a channel spacing of 250KHz; Ultra heterodyne secondary frequency conversion design, with extremely high receiving sensitivity;
- The RF part adopts multi-stage high-performance dielectric filters with excellent anti-interference ability;
- 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;
- Specially designed mute circuit, completely eliminating the impact noise of microphone on and off;
- The microphone uses an Easybuy No.5 battery, which can last for 6-10 hours;
- The microphone adopts a unique boost design, and the decrease in battery power does not affect the overall performance of the handheld microphone;
- The ideal operating radius is up to 80 meters, suitable for various demanding situations; The default configuration is a microphone tube with a yellow backlight on the LCD screen and an aluminum alloy body;
- Equipped with infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver;
- KTV engineering specific model, two microphones, one host. Easy configuration of over 100 KTV rooms, unique product structure design, fast and easy maintenance.
