3 Noise reduction with HiDyn plus

Progress you can hear:

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 up to 110 dB. The 96 dB dynamic range of a CD is thus considerably surpassed.

HiDyn plusis 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 plushas been specially developed for use in high quality radiomicrophone systems.

Note

Only transmitters which are also equipped with HiDyn pluscan work correctly in combination with the EM 3532-U receiver. If this is not the case, the dynamic range is drastically reduced and the transmission sounds blunt and flat. HiDyn pluscannot be switched off on the EM 3532 receiver.
