i
By selecting “LOGIC7
® OFF”, all compatible
formats as they are present on the medium are
played back. Due to the vehicle’s spatial charac-
teristics, an optimal sound experience is not en-
sured on all seats.
i
Please note the following:
For an ideal sound experience at all seats,
the balance and fader should be adjusted to
the center of the passenger compartment
with LOGIC7
® switched on.
The best sound results are achieved by play-
ing high-quality audio CDs and audio DVDs.
For MP3 tracks, the bit rate should be at
least 128 kbit/s.
Surround sound does not function for
mono-signal sources.
In the event of poor radio reception quality,
e.g. inside a tunnel, you should switch off
LOGIC7
®, as a dynamic switch from Stereo
to Mono could occur, resulting in temporary
sound distortion.
With some stereo recordings, the resulting
sound may deviate from conventional stereo
playback.
i
When you insert an audio CD or audio DVD,
it automatically becomes the active audio
source.
