Description of automatic source volume correction
The different audio sources transmit input signals of different strength to the digital sound package control unit -J525-.
This can occur in the case of CDs that have been burnt with different volumes or radio stations that are received with varyingly strong signals.
This means that the output volume would change when a different audio source is selected.
Automatic source volume correction means that the digital signal processor adjusts the signal strength of the different audio sources so that the listener will not hear any change in the volume when, for example, changing the source from CD to radio.
   
1 - Input signal for audio source 1
2 - Digital signal processor
3 - Adjusted output signal
4 - Input signal for audio source 2
