Information to User
Alteration or modifications carried out without appropriate authorization may invalidate the user's right to operate the equipment.
The voltage of the available power supply differs
according to country or region. Be sure that the power
supply voltage of the area where this unit will be used
meets the required voltage (e.g., 230 V or 120 V) written
on the rear panel.
Before plugging in for the first time, read the following
To prevent a fire hazard, do not place any naked flame
sources (such as a lighted candle) on the equipment.
This equipment is not waterproof. To prevent a fire or shock
hazard, do not place any container filed with liquid near this
equipment (such as a vase or flower pot) or expose it to
dripping, splashing, rain or moisture.
When installing this unit, make sure to leave space around
the unit for ventilation to improve heat radiation (at least
60 cm at top, 10 cm at rear, and 30 cm at each side).
Slots and openings in the cabinet are provided for
ventilation to ensure reliable operation of the product, and
to protect it from overheating. To prevent fire hazard, the
openings should never be blocked or covered with items
(such as newspapers, table-cloths, curtains) or by operating
the equipment on thick carpet or a bed.
Operating environment temperature and humidity:
+5 ºC to +35 ºC (+41 ºF to +95 ºF); less than 85 %RH
(cooling vents not blocked)
Do not install this unit in a poorly ventilated area, or in locations
exposed to high humidity or direct sunlight (or strong artificial
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.
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).
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

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

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.

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.

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

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.
