System Configuration
17
ENGLISH
When all audio, video and system
connections 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
No matter which type or brand of speakers
is 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 eliminates the
possibility of distracting sonic disturbances
that occur when a sound moves across
mismatched front channel speakers. 
Speaker Placement
The placement of speakers in a multi-
channel-home-theater system can have a
noticeable impact on the quality of sound
reproduced.
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 60cm off center from the
tweeter in the center channel speaker. They
should also be at least 0,5 meters from the
TV set to avoid interference when the front
left/right speakers are not magnetically
shielded.
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 speakers
slightly forward of the center channel
speaker. If possible, adjust all front
loudspeakers so that they are aimed at ear
height when you are seated in the listening
position.
Using these guidelines, you’ll find that it
takes some experimentation to find the
correct location for the front speakers in
your particular installation. Don’t be
afraid to move things around until the
system sounds correct. Optimize your
speakers so that pans across the front of
the room sound smooth.
Surround speakers should be placed on
the side walls of the room, at or slightly
behind the listening position. The center
of the speaker should face to you. The
speakers should be located so that the
bottom of the cabinet is at least 60cm
higher than the listeners’ ears when seated
in the desired area. 
If side wall mounting is not practical, the
speakers may be placed on a rear wall,
behind the listening position. Again, they
should be located so that the bottom of the
cabinet is at least 60cm higher than the
listeners’ ears. The speakers should be no
more than 2 meters behind the rear of the
seating area.
Subwoofers largely produce non-
directional sound, so they may be placed
almost anywhere in a room. Subwoofer
effect is highly influenced by room size
and shape, and the type of subwoofer used.
Follow the instructions of the subwoofer’s
manufacturer, or experiment with the best
location for a subwoofer in your listening
room.
