There is a difference in
sound quality between
the different audio
sources (radio, CD...).
Check that the audio settings (Volume, Bass,
Treble, Ambience, Loudness) are adapted to
the sources listened to. It is advisable to set
the AUDIO functions (Bass, Treble, Front-Rear
Balance, Left-Right Balance) to the middle
position, select the musical ambience "None"
and set the loudness correction to the "Active"
position in CD mode or to the "Inactive" position
in radio mode.
For optimum sound quality, the audio settings (Volume, Bass, Treble,
Ambience, Loudness) can be adapted to the different sound sources,
which may result in audible differences when changing source (radio,
CD...).
