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.
