6 Noise reduction with HiDyn
plus
™
Progress you can hear:
This transmitter 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 up to 110 dB. The 96 dB
dynamic range of a CD is thus considerably surpassed.
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 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 receivers which are also equipped with
HiDyn
plus
™
can work correctly in combination
with the SKM 3072-U hand-held transmitter. If
this is not the case, the dynamic range is
drastically reduced and the transmission sounds
high and shrill. HiDyn
plus
™
cannot be switched
off on the SKM 3072-U hand-held transmitter.
