1. SAFETY INFORMATION
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-
yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to
properly and safely repair complex products such as those covered by this manual.
Improperly preformed repairs can adversely affect the safety and reliability of the product and may void
the warranty. If you are not a qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
WARNING
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive
toxicant which may cause birth defects or other reproductive harm (California Health & Safety Code, Section
25249.5). When servicing or handling circuit boards and other components which contain lead in solder, avoid
unprotected skin contact with the solder. Also, when soldering do not inhale any smoke or fumes produced.
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement
parts must be of identical designation.
REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que
les pièces de remplacement doivent avoir la même désignation.
(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
The following check should be performed for the
continued protection of the customer and service
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a know earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60Hz outlet and turn the AC power switch on. Any
current measured must no exceed 0.5mA.
ANY MEASUREMENT NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RERTURNING THE
APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related characteristic. These are
often not evident from visual inspection nor the
protection afforded by them necessarily can be
obtained by using replacement components rated for
voltage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components having such features are
identified by marking with a D on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
dose not have the same safety characteristics as the
PIONEER recommended replacement one, shown in
the parts list in this Service Manual, may create sock,
fire, or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Service Manual may be obtained at a
nominal charge from PIONEER.

Connect the speaker output terminals of amplifier or receiver
to these terminals with the accessory two parallel-wire cords.

Used for connecting an additional subwoofer to the system.
Connect this terminal to the SUBWOOFER INPUT terminal
of another subwoofer.

3Subwoofer LEVEL knob
Volume of subwoofer is adjusted with this knob. Turn this
knob clockwise to raise the level.
÷Starting with “MIN“, turn this knob and raise the volume
slowly. If the unit is turned on with the volume set too high,
it could cause hearing and/or speaker damage. Do not
turn the volume up excessively high. The low frequency
sound is apt to be raised too high since it is less disturbing
and harder to detect than high frequencies. Caution must
be taken here since the amplifier and speaker of the S-
W205, S-W105 will be clipped when the output of the am-
plifier or receiver is increased with the subwoofer level set
to “MAX“.
4PHASE selector switch
This switch changes over the subwoofer phase [NORM (in-
phase), REV (opposite phase)] for the combination speak-
ers. Set this switch to suit your choice of bass, according to
the location of the subwoofer.
5CROSSOVER frequency control knob
Select the position according to the woofer level of the
speaker to be combined.
50 Hz … For large-sized speaker
(woofer diameter: 8 inch or more)

If the output of the amplifier (receiver) connected to this
unit is high or if the output has a low range boosted by the
Bass control, Bass boost, or other means, there may be
some sound distortion even if the level of the unit is low-
ered. In this case, lower the output level (Volume, Bass
control, Bass boost) on the amplifier (or receiver) side.

Selecting fine audio equipment such as the unit you’ve just
purchasedisonlythestart ofyourmusicalenjoyment.Nowit’stime
to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries
Association’sConsumerElectronicsGroupwantyoutogetthemost
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
settingyourequipmentatasafelevelBEFOREyourhearingadapts.
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. Published by Pioneer Electronic Corporation.

undetectable until it is too late, this manufacturer and the Electronic

you avoid prolonged exposure to excessive noise. This list of sound
levels is included for your protection.
