VW Series
Wireless Conference System
VW4000M One With 4 Microphone
FEATURE:
Uses the quartz oscillating circuit, has the extremely high frequency stable performance. The multistage narrow band high frequency filter, abandon the minute to eliminate the dry sorrow signal. Because the traditional wireless microphone uses the frequency low silent chain, all is analyzes the radio-frequency signal the intensity, therefore they cannot and need the noise the signal differentiates; In the noisy radio frequency environment (for example digital equipment and so on CD/VCD/LD send out massive overtones) under use, when this launcher signal weak or closure, the silent chain possibly can open suddenly, the receiver can send out the intense demolition noise. In order to solve this problem, this corporate design this section specialized level wireless conference microphone. The multistage narrow band high frequency filter, originate one kind of high-frequency launch receive the noise numerical code suppression electric circuit, but it analyzes the signal the quality is not the signal intensity, when transmitting message micro strong, this system noise acoustic level is low, the receiver lets the sound pass, when the transmitting message weak or does not have the signal, this system noise acoustic level is high, suppresses the electric circuit to be able to cause the receiver noise elimination, removed the irritating demolition sound to pass your receiver possibility.
