How you set up your speakers can affect the bass and the sound field. Note the following points:
≥ Place speakers on flat secure bases.
≥ Placing speakers too close to floors, walls, and corners can result in excessive bass. Cover walls and windows with thick curtains.
≥ Left and right speakers are interchangeable, but front and surround speakers are not.
≥Use only supplied speakers
Using other speakers can damage the unit, and sound quality will be
negatively affected.
≥ Set the speakers up on an even surface to prevent them from falling.
Take proper precautions to prevent the speakers from falling if you
cannot set them up on an even surface.
Main unit
[Note]
≥ Keep your speakers at least 10 mm ( 13 / 32
q) away from the system for
proper ventilation.
≥ To allow for proper ventilation and to maintain good airflow around the
main unit, position it with at least 5 cm (2 q) of space on all sides.
≥ Do not block the ventilation holes of the main unit.
Center speaker
≥ Vibration caused by the center speaker can disrupt the picture if it is
placed directly on the television. Put the center speaker on a rack or
shelf.
≥ To prevent the speakers from falling, do not place directly on top of the
television.
Subwoofer
Place to the right or left of the television, on the floor or a sturdy shelf so
that it will not cause vibration. Leave about 30 cm (11
13 /
16
q) from the
television.
Caution
≥ Do not stand on the base.
Be cautious when children are near.
≥ Do not touch the netted area
of the speakers.
Notes on speaker use
≥ You can damage your speakers and shorten their useful life if you play
sound at high levels over extended periods.
≥ Reduce the volume in the following cases to avoid damage:
– When playing distorted sound.
– When the speakers are reverberating due to a record player, noise
from FM broadcasts, or continuous signals from an oscillator, test
disc, or electronic instrument.
– When adjusting the sound quality.
– When turning the unit on or off.
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.

damage has occurred or if you experience a
sudden change in performance.
