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 safel y, 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.

2. EXPLODED VIEWS AND PARTS LIST
NOTES : 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 the product are used for disassembly.

6.1 IDLE CURRENT ADJUSTMENT
CAUTION : Heatsinks’ (Q323–Q326) DC level is equal to +B or –B.
Don’t touch them or you will be electricary chocked.
1. Connect the measuring instrument as Fig.6–1. (R415 or R416)
2. Set VR301 and VR302 to minimum.
3. Set the POWER switch to ON.
4. Adjust VR301 (VR302) so that the voltage between both sides of R415 (R416) becomes 16mV±1mV.
(Within 10 seconds from when the relay is turned ON)
5. Ages for 7 minutes.
6. Adjust VR301 (VR302) so that the voltage between both sides of R415 (R416) becomes 11mV±1mV.

7.2 CIRCUIT DESCRIPTION
M-10X
Use a wide range linear circuit of A-607R series
for voltage stage, and use HEX POWER MOSFET for output stage.
This circuitry eliminates source resistance, and reduce
power loss in large amount with super low capacity
resistor of output stage device and realize the low
generation of heat, low source voltage.
This circuitry eliminates source resistance and listing
electric coil, and achieve the damping factor that is flat
with band (20Hz - 20kHz).

NOTE:
The protection function will operate in case of internal amplifier
malfunction or in case of external causes such as static electricity or speaker terminal short circuits. When the protection function operates, the POWER indicator flashes, and the unit goes
out into standby mode.
If this occurs, check the speaker terminals and speaker cords to
make sure they are not shorted, then press the STANDBY/ON
button to turn on the unit.
If the protection function then operates again, unplug the power
cord and contact a service center.
