HiDyn
plus
noise reduction
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 radio in wireless audio transmission to up to 114 dB.
HiDyn
plus
is a wideband compander system which compresses the
audio signal in the transmitter in a ratio of 2:1 (related to dB). In the
receiver the signal is expanded in an identical and opposite way in a
1:2 ratio to restore the original signal.
HiDyn
plus
has been specially
developed for high quality radiomicrophone systems.
Note:
Only transmitters and receivers that are equipped with
HiDyn
plus
can work correctly with each other. If non
HiDyn
plus
equipment was
mixed with
HiDyn
plus
, the dynamic range would be drastically
reduced and the transmission would sound blunt and flat.
HiDyn
plus
is permanently active and cannot be switched off.
