Your harman/kardon® audio system
features the innovative LOGIC7® multi-
channel surround sound technology
developed for the professional record-
ing industry.
By selecting the “LOGIC7 Surround”
function, LOGIC7
® will be activated.
LOGIC7
® converts any 2-channel ma-
terial into breathtaking multi-channel
surround sound and that without the
unnatural interpretation of many of to-
day’s surround sound techniques.
LOGIC7
® is not an artificial “effects”
button. It automatically adapts itself to
the incoming source material, adjust-
ing the seven outputs based on the
original acoustic intent of the studio
master.
i
harman/kardon LOGIC7® creates a
true 360-degree “enveloping” sound-
field with a maximum “audio sweet-
spot” for all passengers.
harman/kardon LOGIC7
® sets a new
benchmark in musical clarity and sepa-
ration, giving the listener the impres-
sion of actually “being there”.
LOGIC7
® playback works with all con-
ventional stereo audio sources (e.g.
stereo CD or stereo radio).
If the radio reception is poor, the sys-
tem should be switched back to Stan-
dard stereo playback. Switching back
to Standard stereo playback may im-
prove audio quality.
