POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by
tugging the cord and never touch the power cord when your
hands are wet as this could cause a short circuit or electric
shock. Do not place the unit, a piece of furniture, etc., on the
power cord, or pinch the cord. Never make a knot in the cord or
tie it with other cords. The power cords should be routed such
that they are not likely to be stepped on. A damaged power cord
can cause a fire or give you an electrical shock. Check the
power cord once in a while. When you find it damaged, ask
your nearest PIONEER authorized service center or your dealer
for a replacement.
S002_En
If the AC plug of this unit does not match the AC outlet you
want to use, the plug must be removed and appropriate
one fitted. Replacement and mounting of an AC plug on
the power supply cord of this unit should be performed
only by qualified service personnel. If connected to an AC
outlet, the cut-off plug can cause severe electrical shock.
Make sure it is properly disposed of after removal.
The equipment should be disconnected by removing the
mains plug from the wall socket when left unused for a
long period of time (for example, when on vacation).
D3-4-2-2-1a_A_En
CAUTION
The POWER switch on this unit will not completely shut off
all power from the AC outlet. Since the power cord serves
as the main disconnect device for the unit, you will need to
unplug it from the AC outlet to shut down all power.
Therefore, make sure the unit has been installed so that
the power cord can be easily unplugged from the AC outlet
in case of an accident. To avoid fire hazard, the power cord
should also be unplugged from the AC outlet when left
unused for a long period of time (for example, when on
vacation).

÷ 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-EW2 is
especially effective.
Dolby* Digital
Dolby Digital is the name of the Dolby Surround multi-
channel 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.
FEATURES
7 85 W power that serves video software playback such as
Dolby* Digital with a wide dynamic range.
7 Equipped with 16 cm driver
7 Turnover frequency can be continuous (50 Hz to 200 Hz).
7 Phase conversion switch (0°/180°).

IN COMBINATION WITH SPEAKERS
The frequency characteristics of the S-EW2 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-EW2 in an
ordinary listening room is better than the chart indicates
when positioned adequately.

INSTALLATION

Speaker Installation
The subwoofer plays back the bass in monaural, making use
of the fact that the human ear loses the sense of direction of
lowpitched sound. Since the sense of direction is lost, the
subwoofer can be installed almost anywhere. If it is installed
too far away, however, the sound from the left and right
speakers may become unnatural.

NOTE:
÷ 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

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.
