Placement of speaker systems

The illustration below is an example when enjoying Dolby Pro Logic
Surround system and SFC function.

The listening position at which the effect is the greatest is a position
slightly to the rear of a center position of five-speaker systems.
However the position should be adjusted to your personal prefer-
ence, because the effect varies to some degree depending upon
the source.

The sound reproduced by a speaker is easily influenced by such
factors as room acoustics and the systems location in the room.
Before finally deciding where the speakers are to be placed, please
read the following information carefully.

o The bass sound will be increased if the speakers are placed on
the floor or close to a wall due to the reflection of sound.
it is therefore possible to adjust the bass sound to some extent by
adjusting the speakers distance from the wall and/or floor.

0 Undesirable resonance or sound reflection will occur if the speak<
ers face a hard wall or window. Curtains or similar materials can
be used to prevent these reflections.

a To prevent possible acoustic feedback the speaker system should
be kept away from the turntable. FeedbaCk (howling) can result
from vibrations from the speakers.

0 Keep the speakers away from sources of heat, high humidity and
direct sunlight.

Note tor front/center speakers

These speakers are made so as to be able to be used in close
proximity to the TV, but irregular coldring may result due to how the
system is placed. If such distortion occurs, turn off the TV for some
time between 15 and 30 minutes. The demagnetizing function of the
TV will eliminate the distortion. It the irregular coloring is still visible,
then move the speakers further away from the TV.

Please note that it there is a magnetic object near the TV, irregular
coloring may result due to the interaction between the TV and the
speaker.
