»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
