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 performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not 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 This product contains lead in solder and certain electrical par ts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65
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 known 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 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.
Reading should not be above
0.5 mA
Earth ground
Device under test
Also test with plug reversed (Using AC adapter plug as required)
Leakage
current
tester
Test all exposed metal surfaces
AC Leakage Test
ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A PO­TENTIAL SHOCK HAZARD AND MUST BE COR­RECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appli­ance have special safety related characteristics. 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 on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, 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.

POWERED SUBWOOFER

1 Power switch (POWER)
When pressed, power is turned ON; when pressed again, power is
turned OFF.
2 Power Indicator
Illuminates when the power is on.
3 Phase switch (PHASE 0˚ / _ 180˚)
When depressed (_ 180˚), the output phase becomes the reverse of the input signal, and when raised ( 0˚ ), it is in the same phase
as the input signal. ÷ Normally, the switch is set to ( 0˚ ).
But when the sound connection between the subwoofer and
the left and right speakers sounds unnatural, try switching to
180˚ and set the switch in the position where the sound is natural.
4 Level knob (LEVEL)
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 stereo amplifier.
5 Turnover knob (TURNOVER)
Sets the high limit of the frequency played back by the subwoofer. ÷ Setting Criteria
50Hz ... when the diameter of the left/right speakers is 20-cm or more.
100Hz . when the diameter of the left/right speakers is 10 – 25-cm.
200Hz . when the diameter of the left/right speakers is 12-cm or less.

6 Line Level Input terminal (LINE LEVEL INPUT)
Connects to the stereo amplifier’s SUBWOOFER PRE-OUT terminal, with the specially provided RCA plug cord.
7 Line Level Output terminal (LINE LEVEL OUTPUT)
Used for connecting other equipment through the amplifier.
8 Speaker Level Output terminals
(SPEAKER LEVEL OUTPUT)
When the speakers output terminals on the stereo amplifier are connected to this unit’s SPEAKER LEVEL INPUT terminals 9 and used as the unit’s input signal, these terminals are used to connect the left and right speakers via the unit.
