Professional wireless conference microphone
DV-9290
Efficient distance of 30m, 10 units can be used at the same time.
The PLL frequency synthesized phase-locked loop technology can be used with adjustable frequency and transmission power to avoid interference frequency.
Integrate bus control of CPU with digital LCD interface display for easy operation and excellent performance.
With the Audio Compression-Extension technology, the noise is greatly reduced and the dynamic range is increased.
The function of suppressing and weakening the return whistle can effectively reduce the return whistle.
The receiver uses multi-stage high frequency amplification, equipped with a high-quality capacitive pickup head, and the system has a very high sensitivity.
Diversification technology;
Channel 200 can be adjusted to allow multiple sets of simultaneous use without interference.
The panel can set working distance, display mode and panel lock function.
Electric monitoring, electronic volume.
