Your vehicle is equipped with the harman/
kardon LOGIC7
® Surround Sound system.
You can select between “
LOGIC7®On” and
“
LOGIC7®Off”.
harman/kardon LOGIC7
® Surround Sound
is available for the following operating
modes:

Radio (FM only)

SatRadio*

CD audio

DVD audio (MLP, DTS, PCM and Dolby
Digital audio formats)

MP3 (including PCMCIA memory card)

Aux

DVD video (PCM, DTS and Dolby Digital
audio formats)
i As some DVDs contain both stereo and also
multi-channel audio formats, it may be neces-
sary to set the audio format (
page 66).
i The “LOGIC7®On” function of the harman/
kardon LOGIC7® Surround Sound system per-
mits the playback of discrete 5.1 and stereo re-
cordings with an optimal surround sound
platform for each passenger. Music and films on
CD or audio and video DVDs with high-resolution
surround formats, such as MLP, DTS or Dolby
Digital, are played with optimum sound.
The LOGIC7
® distributes the 5.1 surround infor-
mation over the 12-channel system architecture
to provide the optimum sound in all seats. This
produces the sound characteristics as intended
by the sound engineer during the original record-
ing.
harman/kardon LOGIC7
® converts all two-chan-
nel stereo sound sources into multi-channel sur-
round sound. The surround information stored
during the original recording is read out using
LOGIC7
® and likewise distributed over the
12 channels. No effects are created during the
process, anything that was always on the record-
ing is just made audible again.
Moreover, harman/kardon LOGIC7
® draws the
audible sound source away from the individual
loudspeakers, thus creating a natural 360°
sound platform for each passenger.
i By selecting “LOGIC7® Off”, the playback
of all playable formats is performed as on the ex-
isting medium. Due to the spatial conditions in
the vehicle, optimal sound is not possible in all
seats.
i Discs supporting the above-mentioned au-
dio formats display the following logos

Dolby Digital

DTS

MLP

Setting the surround sound
For surround sound, you can select be-
tween “
LOGIC7®On” and “LOGIC7®Off”.
Select “Sound” K “Surround”.
To select the setting: Rotate ymz or
slide
qmr.
To save setting: Press n.
The setting is stored and the menu is
exited.
To exit menu without changes: Press
the
í button or slide omp.
i Please note the following:

For an optimal sound in all seats, balance
and fader should be set to the centre of the
passenger compartment with LOGIC7
®
switched on.

The best sound results are achieved when
playing high-quality audio and video DVD
discs.

For MP3 tracks, the bit rate should be at
least 128 kbps.

Surround playback does not function with
mono signal sources such as the medium
wave range in radio mode.

In the case of poor radio reception quality,
e.g. in tunnels, LOGIC7® should be switched
off, as otherwise a dynamic switchover from
stereo to mono and thus temporary sound
characteristic shifts can occur.

With certain stereo recordings, the sound
characteristic may deviate from convention-
al stereo playback.
