Installation
Positioning For Optimal Surround Sound
This speaker system can provide full Surround sound. To enjoy
the full effect of the Surround sound field, please position the
speakers as described below.
Place the left and right speakers at opposite sides of your TV.
Angie the speakers towards the listening area to enhance
the stereo effect.
Place the center speaker above or below the TV, so that the
center of the speaker is aligned with the center of the TV. Tilt
the speaker upward or downward so that it is directly facing
the listening area.
Place the rear (surround) speakers as high as possible, either
directly to the sides of the listening area or else slightly be
hind the listening area. Adjust the angles so that these speak
ers are facing directly towards the listeners. ’
Place the subwoofer near a wall to enhance the depth of the
bass. For deepest overall bass output, place the subwoofer
in a corner.
CAUTION (Subwoofer only)
To assure adequate ventilation, observe the following points
when setting up the subwoofer.
• Set the subwoofer so that the heat sink is at least 10 cm
(4 inches) away from the wall.
• Be sure that the heat sink is not covered or blocked. Do
not drape sheets or other coverings over the subwoofer.
• This subwoofer must be set up vertically. Please do not
set it horizontally.
Vertical installation
Feedback (Howling)
Installing the subwoofer too close to an analog record player
may result in howling, caused by feedback of sound into the
player. You can correct the problem by reducing the subwoofer
volume (turn the VOLUME dial counterclockwise) or by moving
the subwoofer further from the player.
In rare cases, feedback may also occur with cassette decks or
with CDs, laser disc, and DVD players. Again, you can correct
the problem by reducing the subwoofer volume or moving the
subwoofer.
■ About Using Speakers Near a TV
The front and center speakers include magnetic shielding and
can therefore be installed close to a TV set. Note, however, that
placing speakers too close to a TV may in some cases produces
distortion in the color reception. To ensure that there is no prob
lem with color reception, proceed as follows.
1. Install the front and center speakers first (do not install the
subwoofer yet), then turn on the TV and check that color re
production is normal. If color is distorted, turn the TV off for
15 to 30 minutes, then turn it back on and check again. (This
allows the TV's degaussing circuitry to correct for the mag
netic field from the speakers.) If distortion is still present,
move the speakers further from the TV.
2.
Install the subwoofer. If color distortion is noticeable, turn
the TV off for 15 to 30 minutes, then turn it back on and check
again. If distortion is still present, move the subwoofer fur
ther from the TV.
Installation Methods
• On Floor or Shelf
Place the speakers on the floor or on a shelf or other horizontal
stable surface. Keep in mind that speakers are not fixed into
place, so be careful to avoid knocking them over.
• On the Wall
The front, center, and rear speakers include mount halls for wall
mounting. You can hang the speakers on the wall either verti
cally or horizontally.
For vertical mount, you use only one screw and hang the speaker
from its upper mount hole only. For horizontal mount, you need to
set two screws into the wall at the appropriate distance so that
you can hang the speaker from both mount holes. Proceed as fol
lows. Note that the subwoofer cannot be mounted on the wall.
To hang a speaker vertically:
1. Screw a single screw into the wall at the desired location.
Screw it only part way in, so that the screw projects 7 to 9
mm (1/4 to 3/8 inches) outward from the wall surface.
2. Flang the speaker by fitting
the top mount hole (at the
upper rear of the speaker)
over the extending part of the
screw.
Confirm
that
the
speaker is held firmly and se
curely in place.
To hang a speaker horizontally:
1. Screw two screws into the walls 76 mm (3 inches) apart, mak
ing sure that screws are horizontally level. Screw each screw
only part way in, so that it projects 7 to 9 mm (1/4 to 3/8 inches)
outward from the wall surface.
2. Flang the speaker by fitting
the two mount holes (at the
rear of the speaker) over the
extending part of the screws.
Confirm that the speaker is
held firmly and securely in place.
7~9 mm
(1/4-3/8")
Precautions
Please observe the following precautions when mounting speakers
onto the wall.
•
Be sure that the wall you are using is strong enough to support
the full weight of the speaker (approx. 1.2 g [2.6 Ibl).
•
Wall screws must be purchased separately. Be sure to use
screws that are appropriate for the wall you are using, and that
are long enough to provide sufficient strength.
•
If you are uncertain about the wall's support strength, the type
of screw to use, or any other points regarding this type of instal
lation, please consult a contractor or other qualified person be
fore proceeding.
Be sure to follow the procedure given here when carrying out in
stallation.
Kenwood can assume no liability for injury or damage that may
occur if a speaker setup falls from the wall as a result of incorrect
installation or insufficient support strength.
