»HIDYN plus®« NOISE REDUCTION SYSTEM

The »HIDYN plus®« noise reduction system serves to reduce the effects of RF interference fields. It increases the signal-to-noise ratio and gets close to about 110 dB for peak modulation.

»HIDYN plus®« is a wideband compander system. It is a combination of a compressor at the transmitter (ratio 2:1) and an expander at the receiver, the compressor reducing the volume of the signal and the expander restoring it. The optimized dynamic range and the control amplifier in the transmitter effectively reduce modulation problems.

»HIDYN plus®« has been expecially developed by Sennheiser for studio and stage applications.

Its features:

•extemely low degree of noise modulation

•level compensation

•excellent dynamic range due to the control amplifier
