3 Noise reduction with HiDyn stage
This receiver is equipped with HiDyn stage , the Sennheiser noise
reduction system that has been specially developed for stage use.
HiDyn stage reduces RF interference and increases the signal-to-noise
ratio in wireless audio transmission.
HiDyn stage 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.
Note
Only transmitters which are also equipped with HiDyn
stage can work correctly in combination with the EK
3053-U receiver. If this is not the case, the dynamic
range is drastically reduced and the transmission sounds
high and shrill.
HiDyn stage cannot be switched off on the EK 3053-
U receiver.
