DB Technologies WM220M manual wireless microphone - HANDHELD RADIOMICROPHONE

(This text is machine translated) The WM 220 system operates in the VHF range with diversity technology, that is, it uses two antennas spaced apart, to ensure interference-free reception. The system continuously monitors the signal quality on both antennas, to automatically and silently switch to the one that offers the best signal-to-noise ratio.
