COMAND introduction

The "LOGIC7 on" function of the harman/
®
®
kardon LOGIC7 Surround Sound system allows
playback of discrete 5.1 and stereo recordings
with an optimum surround sound stage for each
passenger. It enables optimum playback of mu-
sic and films on a CD or audio and video DVDs
with high-resolution surround formats, such as
MLP, DTS or Dolby Digital.
For ideal sound perception from all seats,
®
LOGIC7 distributes the 5.1 surround informa-
tion over the 13-channel architecture. This re-
sults in sound characteristics like those intended
by the sound engineer when the original was re-
corded.
®
Harman/kardon LOGIC7 converts each two-
channel stereo sound source into multi-channel
®
surround sound. LOGIC7 reads the surround in-
formation stored during the original recording
and distributes it over the 13 channels. This does
not create any special effects; you can simply
hear what was always there.
In addition, harman/kardon LOGIC7
the perceived sound source away from the loud-
speakers and thereby generates a natural 360°
sound stage for every passenger.
