The
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.
i
By 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.
i
Balance and fader will be set to the default
value (0/0) automatically by activating or deacti-
vating LOGIC7
®
.
i
Please note the following:
앫
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.
앫
The best sound results are achieved when
playing high-quality audio CDs.
앫
For MP3 tracks, the bit rate should be at
least 128 kbit/s.
앫
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.
앫
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.
앫
With certain stereo recordings, the resulting
sound characteristic may deviate from con-
ventional stereo playback.
