Positioning the speakers

STEP
How you set up your speakers can affect the bass and the sound field. Note the following points:

≥ Placing speakers too close to floors, walls, and corners can result in excessive bass. Cover walls and windows with thick curtains.
≥ Left and right front speakers are interchangeable.
FRONT SURROUND

placed directly on the television. Put the center speaker on a rack or
shelf.

Place the front, center, and surround speakers at approximately the
same distance from the seating position.
The angles in the diagram are approximate.
Main unit
(with digital transceiver)
≥ Place the surround speaker
within approximately 10 m (33 ft)
from the main unit.
∫ Additional note for wireless setup
To avoid possible interference, do not place the surround
speaker near any of the following devices.
The surround speaker uses the same radio frequencies as other devices
that may be present in your home.
The surround speaker will automatically seek a clear channel if any of
these other devices interfere with its communication. When this
happens, the wireless link indicator (" [W] ") flashes on the main unit,
and there is a brief interruption in audio coming from the surround
speaker.
This is the normal operation of the product working to assure the best
possible performance of your Home Theater System.
If the interference persists, try moving the other devices to another
location outside the range of the surround speaker.
If irregular coloring occurs on your television
The front and center speakers are designed to be used close to a
television, but the picture may be affected with some televisions and
setup combinations.
If this occurs, turn the television off for about 30 minutes.
The demagnetizing function of the television should correct the problem.
If it persists, move the speakers further away from the television.
Caution
≥ The main unit and supplied speakers are to be
used only as indicated in this setup. Failure to
do so may lead to damage to the amplifier and/or
the speakers, and may result in the risk of fire.
Consult a qualified service person if damage has
occurred or if you experience a sudden change
in performance.
≥ Do not attempt to attach these speakers to walls
using methods other than those described in
this manual.
