UHF gooseneck microphone isolation shield mic microphone wireless conference system


Features of UHF gooseneck microphone isolation shield mic microphone wireless conference system

1. Using UHF550-980mhz band, the application of PLL frequency synthesis phase locked loop technology, frequency adjustable, transmission power adjustable, avoid interference frequency
2. Integrated CPU bus control, with digital LIQUID crystal interface display, easy operation, outstanding performance.
3. Adopt multi-stage narrowband high frequency and medium frequency selection filter, fully eliminate interference signal.
4. Adopting audio compression and extension technology, the noise is greatly reduced and the dynamic range is enlarged.
5. It is equipped with the function of inhibiting and weakening back input scream, which can effectively reduce back input scream.
6. The receiver uses multistage high frequency amplification, with high sensitivity.
7. Multiple noise monitoring circuit, AD hoc ID code verification system, so that it has good anti-interference characteristics.
8. The selection of chips and high quality parts, so that the machine excellent sound quality.
9. Wide use range of more than 100 meters, the ideal wide use range of 60 meters.
