Sennheiser EK 3041-U manual Noise reduction with HiDyn plus

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.
