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.
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.
Health & Safety Code Section 25249.6 – Proposition 65
(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 60Hz outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.
Reading should
not be above
0.5mA
Earth
ground
Device
under
test
Also test with
plug reversed
(Using AC adapter
plug as required)
Test all
exposed metal
surfaces
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
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.

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.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
•
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

¶ 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 the VOLUME CONTROL to minimum, BASS TONE CONTROL to center, TREBLE TONE CONTROL to center and BALANCE CONTROL
to center. 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.

2 STANDBY/ON switch/indicator
This is the switch for electric power.
This switch does not function unless the POWER OFF/
ON switch is set to ON.
ON: When set to the ON position, power is supplied
and the unit becomes operational.
STANDBY : When set to the STANDBY position, the main
power flow is cut and the unit is no longer fully
operational. A minute flow of power feeds the unit
to maintain operation readiness.
When the STANDBY indicator lights, the unit is in
STANDBY.
NOTE:
When performing timer recording with this unit, be sure to set
the POWER STANDBY/ON switch to ON.

7 REC SELECTOR switch /indicator(For TAPE 1/CD-
R/MD terminals)
This switch is used to select the recording source component.
The signal from the selected component is output at the TAPE1/
CD-R/MD jacks for recording. To select a recording source component, press the REC SELECTOR switch so that the indicator
of the desired source component lights up. When this switch is
set to [TUNER] or [CD], the signal from the selected component
can be recorded regardless of the input selector switch and
TAPE2 MONITOR button settings.
CD: To record from the equipment connected to the CD
terminals.
TUNER : To record from the equipment connected to the
TUNER terminals.
SOURCE: To record from the equipment selected by the IN-
PUT SELECTOR knob.

TAPE 1/CD-R/MD is output. Set to this position when
not recording; the cassette deck will be disconnected,
improving sound quality.

8 BALANCE control
Should normally be left in the center position. Adjust the balance
if the sound is louder from one of the speakers. If the right side is

[DIRECT]
Use this button when you do not wish to pass the output from
input terminal equipment through the various frequency adjusting circuits (BASS, TREBLE, BALANCE, LOUDNESS).
On : The indicator lights. The signals input through the input
terminals are reproduced without passing through the
various frequency adjusting circuits. This results in flat,
pure sound which is a more faithful reproduction of the
input source.
Off : The indicator goes out. The signal passes through the
various frequency adjusting circuits.
[SB MODE]
The SB mode is a special mode in which the amplifier does not
accept remote control except power ON/OFF (But all of the facilities can be controled by manual as same as SB mode OFF.).
Fix the VOLUME control near the center position.In this mode,
the set can be used as a power amplifier which amplifies the
LINE/SURROUND BACK input (the function name is LINE/SB)
with a input sensitivity of 1V.
For example, when the set is combined with one of Pioneer's
Surround Back compatible receiver, the set can be used sa the
Surround Back amplifier.
(For details, please refer to the instruction manual of the receiver.)
0 LOUDNESS button/indicator
Use when listening at low volume level.
On : The indicator lights. Boosts low and high frequencies to
give added punch to playback even at low volume level.
