HiDyn plus is a wideband compander system which compresses
the audio signal in the transmitter in a ratio of 2:1 (related to dB). In the receiver the signal is expanded in an identical and opposite way in a 1:2 ratio to restore the original signal. HiDyn plus has been specially developed for high quality radiomicrophone systems. Note: Only transmitters and receivers that are equipped with HiDyn plus can work correctly with each other. If non HiDyn plus equipment was mixed with HiDyn plus, the dynamic range would be drastically reduced and the transmission would sound blunt and flat. HiDyn plus is permanently active and cannot be switched off.
