1. SAFETY INFORMATION
This service manual is intended for qualified service technicians; it is not meant for the casual do-ityourselfer. 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 parts must be of identical designation.
(slow operating fuse) on PCB indicate that replacement
REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) (fusible de type rapide) et/ou Les symboles de fusible 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.
(fusible de type lent) sur CCI indiquent que
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.

AUTO POWER OFF ON/OFF switch. ON: AUTO POWER OFF function is operating. OFF: Normal power supply conditions
6 Subwoofer input terminals (SPEAKER LEVEL INPUT)
Connect the speaker output terminals of amplifier or receiver to these terminals with the accessory two parallel-wire cords.
3 Subwoofer 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 SW205, S-W105 will be clipped when the output of the amplifier or receiver is increased with the subwoofer level set to "MAX".
7 Speaker output terminals (SPEAKER LEVEL OUTPUT)
Connect the speaker input terminals to these terminals with the two parallel-wire cords. When the SPEAKER LEVEL INPUT is in use.
8 Subwoofer input terminal (LINE LEVEL INPUT)
Connect SUBWOOFER output terminal of the amplifier or receiver to this terminal with the accessory RCA cord.
4 PHASE selector switch
This switch changes over the subwoofer phase [NORM (inphase), REV (opposite phase)] for the combination speakers. Set this switch to suit your choice of bass, according to the location of the subwoofer.
9 Subwoofer output terminal (LINE LEVEL OUTPUT)
Used for connecting an additional subwoofer to the system. Connect this terminal to the SUBWOOFER INPUT terminal of another subwoofer. 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 lowered. In this case, lower the output level (Volume, Bass control, Bass boost) on the amplifier (or receiver) side.
5 CROSSOVER 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)

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. Decibel Level 30 40 50 60 70 80 Example Quiet library, soft whispers Living room, refrigerator, bedroom away from traffic Light traffic, normal conversation, quiet office Air conditioner at 20 feet, sewing machine Vacuum cleaner, hair dryer, noisy restaurant Average city traffic, garbage disposals, alarm clock at two feet. THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CONSTANT EXPOSURE 90 Subway, motorcycle, truck traffic, lawn mower 100 Garbage truck, chain saw, pneumatic drill 120 Rock band concert in front of speakers, thunderclap 140 Gunshot blast, jet plane 180 Rocket launching pad

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.
