IN COMBINATION WITH SPEAKERS
The frequency characteristics of the S-W301/S-W501/S-W601 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-W301/S-W501/S-W601 in an ordinary
listening room is better than the chart indicates when positioned
adequately.
• 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-W301/S-W501/S-
W601 is especially effective.

4 Listening position
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.
•

6 Rear left speaker
7 Rear right speaker
NOTES:
• Position the left and right channel speakers at equal distances from
the TV set and approximately 1.8 meters (6 ft.) 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 (3.3 ft.) above the listener’s ears.
Installation Precautions
• Do not attach the subwoofer to the wall or ceiling. They may fall off
and cause injury.
• 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.
• 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.
• 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.

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.
The subwoofer is not magnetically shielded and so should not be
placed near a TV or monitor. Magnetic storage media (such as
floppy discs and tape or video cassettes) should also not be kept
close to the subwoofer.
MAINTENANCE OF EXTERNAL SURFACES:
• Clean the surface by wiping with a 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.
PANEL FACILITIES
FRONT PANEL

1 Power Indicator (STANDBY/ON)
Lights blue when the power has been switched ON. When AUTO
STANDBY switch is set to ON, lights blue whenever the speaker receive
an audio signal. If the power is switched OFF only briefly, the indicator
lights blue when power is restored. If no signal is present for more than
12 minutes, the subwoofer automatically reverts to standby mode and the
power indicator lights red. If, subsequently, a signal is received, power
automatically comes back on and the power indicator lights blue.
NOTE:
• If you are planning on switching the unit OFF for a long period of
time, make sure to check that the indicator light has gone out after
switching OFF.
2 Power switch (POWER)
Switches the subwoofer between ON and OFF.
3 Volume knob (VOLUME)
Sets the subwoofer volume.
• Turn the knob slowly from the MIN position.
• With this unit, the bass level can be independently set, so do not
turn up the bass on the AV amplifier.
4 Crossover knob (CROSSOVER)
When using the subwoofer, set the upper frequency limit for the
subwoofer (
50 Hz
to
200 Hz
) so that it complements the output from
your other speakers.
When using the bass management features of an AV receiver, set to
BYPASS ON
in order to use the low-pass filter of the AV receiver for
high quality sound.
5 Bypass switch (BYPASS)
When set to
ON
, the audio signal is routed to the woofer unit,
bypassing the amplifier’s crossover circuit.
6 Phase switch (PHASE 0º /180º)
When set to
180º
, the output phase becomes the reverse of the input
signal, and when set to
0º
, it is in the same phase as the input signal.
• Normally, the switch is set to
0º
.
But when the sound connection between the subwoofer and the
left and right speakers sounds unnatural, try switching to
180º
and set the switch in the position where the sound is natural.
• When using two or more subwoofers together, make sure that the
phase switch of all of them are set to the same position.
7 Auto Standby switch (AUTO STANDBY)
Switches the Auto Standby feature on/off.
When switched
ON
(the default setting is
OFF
), the Auto Standby
feature becomes active. In this mode, if there is no input signal for 12
minutes the system automatically switches to standby. The power is
automatically switched on again if an input signal is detected.
NOTE:
There may be cases where a connected component outputs noise or
some other non-audio signal which causes this system to
automatically power on when in Auto Standby mode. If this happens,
switch off the Auto Standby mode and switch the system on/off
manually.
8 Line Level Input terminal (LINE LEVEL INPUT)
Connect to the SUBWOOFER PREOUT terminal of an amplifier or
receiver, with the specially provided RCA plug cord.
9 Line Level Output terminal (LINE LEVEL OUTPUT)
Used for connecting other equipment through the amplifier. The
signal output from this jack is not affected in any way by the settings
of the various controls on the unit.
10 AC CORD
Connect the AC cord to a AC socket (in the room).
CONNECTIONS
Before making or changing any connections, switch off the power
and disconnect both this unit and the amplifier/receiver from the
AC outlet.
LINE LEVEL CONNECTION
This connection is for an amplifier or receiver equipped with a
SUBWOOFER PREOUT
terminal. Connect to the
LINE LEVEL INPUT
terminal on this unit, using the specially provided RCA plug cord.
NOTE:
• When connected to the
PREOUT
terminal for surround center
channel on the amplifier or receiver, the bass is heard only on the
center channel, so it will be insufficient.
OPERATION
For details regarding operating part functions, refer to
PANEL
FACILITIES
above.
1. Turn the POWER switch (2) ON.
• If the unit’s power cord is connected to a switched AC outlet on
the amplifier or receiver and the switch is left ON, the unit can be

Operating Instructions
POWERED SUBWOOFER
Mode d’emploi
ENCEINTE ACTIVE D’EXTREMES GRAVES
Thank you for buying this PIONEER product. Please read through these operating instructions so you will know how to operate
your model properly. After you have finished reading the instructions, put them away in a safe place for future reference.
In some countries or regions, the shape of the power plug and power outlet may sometimes differ from that shown in the
explanatory drawings. However, the method of connecting and operating the unit is the same.

S001_En
Selecting fine audio equipment such as the unit
you’ve just purchased is only the start of your
musical enjoyment. Now it’s time to consider how
you can maximize the fun and excitement your
equipment offers. This manufacturer and the
Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that
lets the sound come through loud and clear without
annoying blaring or distortion-and, most importantly,
without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing
“comfort level” adapts to higher volumes of sound.
So what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by
setting your equipment at a safe level BEFORE your
hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it
comfortably and clearly, and without distortion.
Once you have established a comfortable sound
level:
• Set the dial and leave it there.
Taking a minute to do this now will help to prevent
hearing damage or loss in the future. After all, we
want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will
provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often
undetectable until it is too late, this manufacturer
and the Electronic Industries Association’s
Consumer Electronics Group recommend you avoid
prolonged exposure to excessive noise. This list of
sound levels is included for your protection.
