Surround sound
General notes
If your vehicle is equipped with the harman/
kardon® Logic 7® surround sound system,
you can set the optimum surround sound for
every passenger.
The harman/kardon® Logic 7® surround
sound system is available for the following
operating modes:
Rradio (FM only)
Rsatellite radio
Raudio CD
Raudio DVD (MLP, dts, PCM and Dolby
Digital audio formats)
RMP3 (including SD memory card)
RBluetooth® audio mode
RMedia Interface
Rvideo DVD (PCM, dts and Dolby Digital
audio formats)
RAUX
Because many DVDs contain both stereo and
multi-channel audio formats, it may be
necessary to set the audio format
(Y page 223).
iThe Logic7® On function enables
playback of, e.g. stereo recordings with a
surround sound experience for every
passenger. 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. The resulting
audio experience reflects that intended by
the sound engineer during the original
recording.
iIf you select  LOGIC7® Off, the sound
system plays the tracks as stored on the
medium. Due to the design of the
passenger compartment, an optimum
audio experience cannot be guaranteed for
all passengers.
iDiscs which support the audio formats
mentioned have the following logos:
Dolby Digital
dts
