System Configuration - Harman Kardon AVR80II Owner's Manual

When all audio, video and system con-
nections have been made, there are a few
configuration adjustments to be made. A
few minutes spent to correctly configure
and calibrate the unit will greatly add to
your listening experience.
Speaker Selection and Placement
The placement of speakers in a multi
channel home theater system can have
a noticeable impact on the quality of
sound reproduced. For Home THX opera-
tion it is recommended that the speakers
carry the certification mark of Lucasfilm
Ltd.'s Home THX Division. However, with
careful selection and placement, the
AVR80 will deliver accurate reproduc-
II
tion with any high quality speakers.
No matter which type or brand of speak-
ers are used, the same model or brand of
speaker should be used for the front left,
center and right speakers. This creates a
seamless front soundstage, and elimi-
nates the possibility of distracting sonic
disturbances that occur when a sound
moves across mis-matched front channel
speakers.
For the most accurate and exciting
reproduction of bass frequencies a sepa-
rate subwoofer should be used. When
THX Certified front channel speakers are
used, a separate subwoofer is mandatory,
as THX front and center speakers are not
designed for extreme low frequencies.

The AVR80 may be used with either
II
conventional (point source) surround
speakers or with THX Certified diffuse
surround speakers. No adjustment is
needed to select the type of surround
speaker used.
Speaker Placement
Depending on the type of center channel
speaker in use and your viewing device,
place the center speaker directly above or
below your TV or in the center behind a
perforated front projection screen.
Once the center channel speaker is
installed, position the left and right front
speakers so that they are as far away
from one another as the center channel
speaker is from the preferred listening
position. Ideally, the front channel
speakers should be placed so that their
tweeters are no more than 24" off center
form the tweeter in the center channel
speaker.
Depending on the specifics of your room
acoustics and the type of speakers in use,
you may find that imaging is improved
by moving the front left and right speak-
ers slightly forward of the center channel
speaker. If possible, adjust all front loud-
