INTRODUCTION


BIEMA UHF68 series wireless microphone system is designed to solve noise digital restrained circuit besides normal method, such as improving frequency, multi-level high frequency with narrow band and MF filter. It's effective to make up for the shortage of traditional wireless microphone at interference due to frequency too low,especially a lot of harmonic in CD,VCD and LD by reason of radiation. Even though sometimes the receiver will occur strongly exposure noise as state noise circuit of microphone open abruptly, no interruption will appear since the microphone can be locked itself by PLL phase.Also it has 100 channels to choose for 400frequency free adjustment. No interference occurs even many sets are operating simultaneously.


FEATURES


●UHF 800MHz band is used to avoid interfering frequency.

●Multi-level high frequency with narrow band and MF filter are adopted to eliminate the interference fully.

●All equipped with PLL circuit to achieve steady frequencies and avoid interference when many sets are operating simultaneously.

●With audio compressing & expanding technology, the unit can lower noise but increase the dynamic range.

●It is designed with the function of effective reduction of transfusion feedback.

●Receiver adopts mutil-level high frequency amplification for high sensitivity.

●Multiple noise monitoring circuits ensure strong anti-interference.

●The frequency response is designed with the characteristics of voice frequency: strong low frequency, bright mid frequency and clear high frequency.

●With the best circuit of impulse noise cancellation by power switch, it won’t damage the speakers or affect the program when you turn on or off the equipment.

●The selection of high-quality chip and components makes excellent sound quality.

●The automatic selection of signal is adopted to eliminate receiving dead angle and overcome the receiver’s disavantage of incoherence an instability during sound transmission.
