This product family is equipped with the Sennheiser noise reduction systems HDP and HDX. Both compander systems operate on the same principle (described in the following for HDP) but use different parameters (e.g. time constant, type of control). HDP reduces RF interference. It increases the
HDP has been specially developed for high quality radio microphone systems.
All receivers of the product family feature a AES3 digital audio output for digital mixing consoles. In the receiver the audio signal is digitalized as early as possible so that the noise reduction (compander) can be realized digitally.
Only transmitters and receivers that are equipped with the same compander system can work correctly with each other. If this is not the case, the dynamic range will be drastically reduced and the transmission will sound blunt and flat.
Squelch
Depending on the strength of the received RF signal, the receiver’s audio output is opened or muted. Via the “Squelch” menu, the squelch threshold can be adjusted in 13 steps from 0 to 30 μV.
