Sennheiser EK 3053-U manual Noise reduction with HiDyn stage, Connections and operating elements

3 Noise reduction with HiDyn stage 4 Connections and operating elements

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.
