the balance should be set to the center of
the vehicle interior.
You will achieve the best sound results by
playing high-quality audio and video DVDs.
MP3 tracks should have a bit rate of at least
128 kbit/s.
Surround sound playback does not
function for mono signal sources, such as
for AM radio mode.
If radio reception is poor, e.g. in a tunnel,
you should switch off Logic7 ®
, since it may
otherwise switch dynamically between
stereo and mono and cause temporary
sound distortions.
On some stereo recordings, the sound
characteristics may differ from
conventional stereo playback.

On function creates a
surround sound experience for every
passenger when playing stereo recordings,
for example. It enables optimum playback
of music and films on CD, audio DVD or
video DVD with multichannel audio
formats, such as MLP, dts or Dolby Digital.
This results in sound characteristics like
those intended by the sound engineer
when the original was recorded.
i If you select Logic7
