IN COMBINATION WITH
SPEAKERS

The frequency characteristics of the S-LX70W combined
with small-size speakers are shown below. As shown in
these figures, the low frequency range is improved.

• These special characteristics are obtained in an
echoless chamber. The effect of an additional S-LX70W

RESPONCE (dB)

• With playback of Dolby* Digital, establishment of a
special channel for the subwoofer is recommended;
and with playback of LFE (Low Frequency Effect: sound
effect like the rumbling of the earth, whose purpose is
to intensify the force of the video), the S-LX70W is
especially effective.

Dolby* Digital

Dolby Digital is the name of the Dolby Surround multi­channel digital system that was developed from Dolby
Surround, as a continuation of Dolby Pro Logic Surround.

Dolby Digital is also referred to as a 5.1 channel system.
This is because it has 5 channels in the 20 Hz to 20 kHz
frequency range (front left and right, center, and rear left
and right) and an independent channel for the
subwoofer. The subwoofer channel is also referred to as
LFE (Low Frequency Effect).

The LFE channel is used according to individual tastes to
enhance the bass effect.

NOTES:

• To avoid interference with the picture on a nearby TV
set, use magnetically shielded speaker systems. This
is particularly important for the center speaker since it
is usually located closest to the TV.

• Position the left and right channel speakers at equal
distances from the TV set and approximately 1.8 meters
from each other.

• Install the center speaker above or below the TV so that
the sound of the center channel is localized at the TV
screen.

• The rear (surround) speakers are most effective when
installed in parallel locations directly to the side, or
slightly behind, the listener, at a level about 1 meter
above the listener’s ears.

CAUTION:

When installing the center speaker on top of the TV,
be sure to secure it with tape or some other suitable
means.

Otherwise, the speaker may fall from the TV due to
external shocks such as earthquakes, and it may lead
to endangering those nearby or damaging the
speaker.

4

The subwoofer plays back the bass in monaural, making
use of the fact that the human ear is not very sensitive to
the direction of low-pitched sound. Because of this, the
subwoofer can be installed almost anywhere. If it is
installed too far away, however, the sound from the other
speakers may become unnatural.

Installation Precautions

• Install the unit in a well-ventilated location where it will
not be exposed to high temperatures and high
humidity.

• Do not place the unit near stoves or other heating
equipment or at locations exposed to direct sunlight,
as these can have an adverse effect on the cabinet and
internal components. Also, do not install the unit
where there is too much dust or high humidity, as
these can cause malfunctioning or breakdowns.
(Avoid cooking tables and other locations where the
unit would be exposed to heat, steam and soot.)

• Do not place heavy or large objects on top of the
speaker. Doing so could provoke the speaker to fall,
causing damages or bodily injury. If speakers fall from
their installation locations, they may suffer irreparable
cracks in their finish.

• Keep the unit away from devices such as cassette
decks which are sensitive to magnetic fields.

This speaker system is magnetically shielded.
However, depending on the installation location,

color distortion may occur if the speaker system is
installed extremely close to the screen of a television
set.

If this happens, turn off the power switch of the
television set, and turn it on after 15 to 30 minutes.

If the problem persists, place the speaker system
away from the television set.

5

67

• Do not place the speaker on an unstable surface, as
doing so may cause the speaker to fall and cause
damage or bodily injury.

• Do not place cups, glasses, or other containers with
fluids on top of the units, since the units may be
damaged if the liquid spills.

5

En

• The installation location selected should have a sturdy
floor surface. Mounting the speaker on a long-pile
carpet should be avoided, since the carpet may touch
the driver’s diaphram, causing distorted sound.

• Please install this unit away from the antenna cable of
the tuner, as noise can be caused with installation
close to the antenna cable. In such a case, use this
unit at a position away from the antenna and the
antenna cable, or when playback of extra bass is not
required, switch off the power for this unit.

MAINTENANCE OF EXTERNAL SURFACES

• Clean the surface by wiping with the provided
polishing cloth, or with another soft, dry cloth.

• When the surfaces are very dirty, wipe with a soft
cloth dipped in some neutral cleanser diluted five
or six times with water, and wrung out well, and
then wipe again with a dry cloth. Do not use
furniture wax or cleaners.

• Never use thinners, benzine, insecticide sprays
and other chemicals on or near this unit, since
these will corrode the surfaces.
