4 Noise reduction with HiDyn plus ®
This receiver is equipped with HiDyn plus ® , the Sennheiser noise reduction
system that reduces RF interference. It increases the signal-to-noise ratio in
wireless audio transmission to more than 100 dB.
HiDyn plus ® is a wideband compander system which compresses the AF level
on the transmitter side in a ratio of 2:1 (related to dB), and expands it in an
exactly the same way on the receiver side. The optimisation of the dynamic
range and the supporting effect of the control amplifier in the transmitter
effectively reduce modulation problems.
HiDyn plus ® has been specially developed for use in high quality radiomicrophone
systems.
Note
Only transmitters which are also equipped with HiDyn plus ® can
work correctly in combination with the EK 3041-U receiver. If
this is not the case, the dynamic range is drastically reduced
and the transmission sounds blunt and flat.
HiDyn plus ® cannot
be switched off on the EK 3041-U receiver.
