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 parts 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)
Test all
exposed metal
surfaces
AC Leakage Test
Leakage
current
tester
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.

NOTES:
2.1 PACKING
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
Screws adjacent to mark on product are used for disassembly.

Caution when disassembling.
Even if the power supply cord is pulled out from the outlet, neither C11 nor C12 of the AF ASSY are discharged.
Please discharge C11 and C12 of the AF ASSY with the resistor of 100 Ω or more before removing the AF ASSY or the PO WER SUPPLY ASSY.
As there is a possibility to destroy the transistor, discharge with the resistor of 100 Ω or more.

7. GENERAL INFORMATION
7.1 SINGLE OPERATION METHOD
Single operation method and input level.
The procedure and the input level of a single operation are shown below.
1. Short R85 with 1kΩ.
2. Connect the four “A” points of the figure below.
GNDs are not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND.
The potential of B1GND, B2GND, and B3GND becomes same level as chassis GND by connecting the four “A” points.
2. The power supply of the unit is turned on.
3. The terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages.
CONT
12V 5V 0V
RY ON ON OFF
MUTE OFF ON ON
4. The signal of 10mV is input from the input terminal (JA3333), and the output is confirmed with the speaker terminal (CN3331).
Note :If the music signal is input directly to the input terminal (JA3333) with CD PLA YER etc. , the output becomes a large sound because
there are 40dB GAIN of the amplifier.

Caution when disassembling.
Even if the power supply cord is pulled out from the outlet, neither C11 nor C12 of the AF ASSY are discharged.
Please discharge C11 and C12 of the AF ASSY with the resistor of 100 Ω or more before removing the AF ASSY or the PO WER SUPPLY ASSY .
As there is a possibility to destroy the transistor, discharge with the resistor of 100 Ω or more.
