Professional Wireless Microphone System
Using Multilevel high frequency and mid frequency narrowband filter, so as to dispel any possible interference signals.
Diversity receiver, these transmission system ensure interference-free transmission and minimize dropouts in the RF link, avoid the dead angle.
Special designed circuit on the microphone for clearing up waves of miscellaneous signals.
With Audio compressing-expanding technology, the machine can lower noise an increase the dynamic range. It can also lower re-echo.
Using VHF 200-270 MHz band to avert interference frequency.
There is a volt indication circuit in the microphone which can tell you if it is necessary to change the battery.
