Rear Speakers
•
Place these speakers behind your listening position.
•
If there isn't enough room, place these speakers to face each other.
•
Place them about 60 to 90cm (2 to 3feet) above your ear, facing
slightly downward.
*
Unlike the front and center speakers, the rear speakers are used
to handle mainly sound effects and sound will not come from
them all the time.
Subwoofer
•
The position of the subwoofer is not so critical.
Place it anywhere you like.
•
Usually, it is placed by a corner near the front speakers.
Front Speakers
•
Place these speakers in front of your listening position, facing inwards (about 45°) toward you.
•
Place the speakers so that their tweeters will be at
the same height as your ear.
•
Align the front face of the front speakers with the
front face of the center speaker or place them
slightly in front of the center speakers.
Center Speaker
•
It is best to install it at the same height as the front
speakers.
•
You can also install it directly over or under the TV.
Position of the DVD Player
•
Place it on a stand or cabinet shelf, or under
the TV stand.
Selecting the Listening Position
The listening position should be located about 2.5 to 3
times the distance of the TV's screen size away from the
TV. Example: For 32" TVs 2~2.4m (6~8feet)
For 55" TVs 3.5~4m (11~13feet)

Connecting the Speakers
Black
Press down the terminal
tab on the back of the
speaker.
1
Insert the black wire into the
black terminal (–) and the red
wire into the red (+) terminal,
and then release the tab.
2
Connect the correct color speaker cable
to the same color speaker output terminal
on the rear of the subwoofer, according
to the polarity markings (+/–).
Example: Connect the green center speaker cable
to the green center speaker output terminal on the rear of the subwoofer according to the polarity markings (+/–).
3
Red
•
Do not let children play with or near the speakers.
They could get hurt if a speaker falls.
•
When connecting the speaker wires to the speakers,
make sure that the polarity (+/–) is correct.
Caution
•
If you place a speaker near your TV set,
screen color may be distorted because of
the magnetic field generated by the speaker. If this occurs, place the speaker away
from your TV set.
