Wireless Microphone Headset and Lavalier
U-9000B Headworn
Main characteristics:
1. PLL frequency synthesis phase-locked loop technology is applied, with adjustable frequency and transmission power to avoid interference frequency and mobile phone interference.
2. The bus control of the integrated central processing unit (CPU) and the digital LCD interface display enable easy operation and outstanding performance.
3. Multi stage narrowband high-frequency and intermediate frequency selective filtering is adopted to fully eliminate interference signals.
4. With audio compression expansion technology, the noise is greatly reduced and the dynamic range is increased.
5. It has the function of reinjection howling suppression and attenuation, which can effectively reduce reinjection howling.
6. The receiver adopts multi-stage high-frequency amplification and has extremely high sensitivity.
7. Multiple noise monitoring circuits and special tone locking TONE-LOCK system make it have unparalleled anti-interference characteristics.
8. Excellent chips and high-quality components are selected to make the sound quality of the machine extremely excellent.
9. The maximum use range of the empty space is more than 100 meters, and the ideal use range of the empty space is 50 meters.
