iThe LOGIC7® On function of the
harman/kardon LOGIC7® Surround Sound sys-
tem permits the playback of discrete 5.1 and ste-
reo recordings with an optimal surround sound
platform for each passenger.
The LOGIC7
® distributes the 5.1 surround infor-
mation over the 13-channel system architecture
to provide the optimum sound experience from
all seats. This produces the sound characteristic
as intended by the sound engineer during the
original recording.
Harman/kardon LOGIC7
® converts all two-chan-
nel stereo sound material into multi-channel sur-
round sound. The surround information stored
during the original recording is read out using
LOGIC7
® and likewise distributed over the
13 channels. No effects are created during this
process; only that which was already there be-
comes audible.
In addition, harman/kardon LOGIC7
® moves the
perceived sound source away from the individual
loudspeakers, thus generating a natural 360°
sound experience for each passenger.
iBy selecting LOGIC7® Off, all compatible
formats are played back as they are present on
the medium. Due to the vehicle’s spatial charac-
teristics, an optimal sound experience is not en-
sured from all seats.
iBalance and fader will be set to the default
value (0/0) automatically by activating or deacti-
vating LOGIC7
®.
iPlease note the following:

For an optimal sound experience from all
seats, the balance and fader should be ad-
justed to the center of the passenger com-
partment with LOGIC7
® switched on.

The best sound results are achieved when
playing high-quality audio CDs.

For MP3 tracks, the bit rate should be at
least 128 kbit/s.

Surround playback cannot be activated in
mono-signal sources as AM or Weatherband.
It will not function for mono-signal sources
as, e.g. mono audio tracks on some specific
audio CDs.

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 resulting
sound characteristic may deviate from con-
ventional stereo playback.
