SYSTEM CONFIGURATION  15
System Configuration
When all audio, video and system connections
have been made, there are a few configuration
adjustments that must be made. A few minutes
spent to correctly configure and calibrate the
unit will greatly add to your listening experi-
ence.
Speaker Selection and Placement
The placement of speakers in a multichannel
home-theater system can have a noticeable
impact on the quality of sound reproduced.
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
front-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
Depending on the type of center-channel speak-
er in use and your viewing device, place the
center speaker either 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-front and right-front speakers
so that they are as far away from one another
as the center-channel speaker is from the pre-
ferred listening position. Ideally, the front-chan-
nel speakers should be placed so that their
tweeters are no more than 60 cm above or
below the tweeter in the center-channel speak-
er.
They should also be at least 50 cm from the TV
set to avoid colourings on the TV screen 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 front-right speakers slightly
forward of the center-channel speaker. If possi-
ble, 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 loca-
tion for the front speakers in your particular
installation. Don’t be afraid to move things
around until the system sounds correct. Opti-
mize your speakers so that audio transitions
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 you.
If side-wall mounting is not practical, the speak-
ers may be placed on a rear wall, behind the lis-
tening position. The speakers should be no more
than 2 meters behind the rear of the seating
area.
Subwoofers largely produce nondirectional
sound, so they may be placed almost anywhere
in a room. Actual placement should be based on
room size and shape and the type of subwoofer
used. One method of finding the optimal loca-
tion for a subwoofer is to begin by placing it in
the front of the room, about 15 cm from a wall,
or near the front corner of the room. Another
method is to temporarily place the subwoofer in
the spot where you will normally sit, and then
walk around the room until you find a spot
where the subwoofer sounds best. Place the
subwoofer in that spot. You should also follow
the instructions of the subwoofer’s manufactur-
er, or you may wish to experiment with the best
location for a subwoofer in your listening room.
