Product Detail
Independently designing a new type of base is an ideal equipment for highly demanding advanced conference engineering.
Wide frequency response, clear and transparent sound quality, low noise, and ultra long microphone ON/OFF lifespan.
When the microphone is turned on, the red working indicator light of the sound head lights up.
The gooseneck and base can be separated, suitable for large, medium, and small meetings, public communication, classes, speeches, and other occasions.
Identification of ID code, less susceptible to external interference and influence.
Main features:
*Using UHF640~690MHz frequency band and PLL frequency synthesis phase-locked loop technology, the frequency can be adjusted and 5 sets can be used simultaneously without interference,.
*The overall control of the integrated central processing unit (CPU), combined with digital high-definition LED interface display, is easy to operate and has outstanding performance.
*Adopting multi-stage narrowband high-frequency and intermediate frequency selective filtering to fully eliminate interference signals.
*By adopting audio compression and expansion technology, noise is greatly reduced and dynamic range is increased.
*Equipped with feedback howling suppression and attenuation function, it can effectively reduce feedback howling.
*The receiver adopts multi-stage high-frequency amplification and has extremely high sensitivity.
*Ideal space usage distance of 50 meters.
