Product Description
The industry pioneered the patented technology of automatic manual induction. The microphone can be silenced automatically within 3 seconds (in any direction or at any angle) when it leaves the hand. After 5 minutes, it can automatically save energy and enter standby state. After 15 minutes, it can shut down automatically and cut off the power completely. It is a new concept of intelligent and automatic wireless microphone.
Applications
New audio circuit structure, high-pitched delicate, medium and low frequency strong, especially in the details of the sound has perfect expression. Super dynamic tracking capability makes remote/close pickup radio easy to play.
_New concept of digital pilot technology, a complete solution to the KTV compartment cross-frequency phenomenon, never cross-frequency!
Configured with a scream suppression function circuit, debugging is simpler
_Automatically search non-interference channel function, more convenient installation
The maximum volume of output can be freely limited, and the scope of application is wider.
Host can flexibly set usage times
_UHF band, PLL frequency synthesis
_100*2 channels, channel spacing 250KHz
_Super heterodyne secondary frequency conversion design, with very high reception sensitivity
_The radio frequency part adopts multi-stage high-performance dielectric filter, which has excellent anti-interference ability.
_The first IF uses a sound meter filter and the second IF uses a three-stage ceramic filter, which improves the anti-interference ability very well.
The specially designed silent circuit completely eliminates the impact noise of microphone opening and closing.
The microphone uses the easy-to-buy No. 5 battery and lasts for 6-10 hours.
_Microphone uses unique boost design, battery power decline does not affect the overall performance of the hand.
_Ideal operating radius of 80 meters, suitable for all kinds of occasions
Default configuration for microphone body with LCD screen blue backlight and aluminium alloy
With adjustable transmitting power and adjustable noise threshold, the receiver rear panel is equipped with external noise control knob, and the effective operating radius can be flexibly set between 10m and 80m according to the need.
It has the function of infrared automatic frequency matching, which can make the microphone synchronize to the working channel of the receiver quickly.
_KTV engineering special model, two microphones, a host. Easy to configure more than 100 KTV rooms, unique product structure design, fast and simple maintenance.
