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 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 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 be of identical designation.
(slow operating fuse) on PCB indicate that replacement parts must
REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou de remplacement doivent avoir la même désignation.
(fusible de type lent) sur CCI indiquent que les pièces
(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
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.
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.
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 schematics and 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.
Device under test Test all exposed metal surfaces
Reading should Leakage not be above current 0.5mA tester
Also test with plug reversed (Using AC adapter plug as required)

1 POWER (-- OFF/_ ON) switch
Press to turn power to the unit ON and OFF. This unit cannot be turned ON and OFF using the remote control unit.
5 TAPE 2 MONITOR button/indicator
Use when there is an adaptor component (graphic equalizer, etc.) or cassette deck connected to the TAPE 2 MONITOR terminals. On : Indicator lights when using the adaptor component or listening to the cassette deck. Off : Indicator goes off when not in use.
2 REMOTE CONTROL SENSOR window 3 VOLUME control
Use to adjust the volume level.
NOTES:
÷ When no connections are made to the TAPE 2 MONITOR terminals, or when they are not in use, be sure to set this switch to the off position. (No sound will be heard if it is set to the on position.) ÷ When the TAPE 2 MONITOR indicator is on and the INPUT SELECTOR knob is not set to TAPE 1/MD, the signals which are input through TAPE 2 MONITOR are then output at TAPE 1/MD REC OUT.
4 INPUT SELECTOR knob/indicators
Turn the knob clockwise or counterclockwise so that the indicator lights for your desired input source. Turning the knob clockwise causes the lit indicator to right. Turning counterclockwise causes it to left. CD : For compact disc playback with a CD player. TUNER : For AM or FM broadcast reception with a tuner. PHONO : For record playback with a turntable. LINE : Set to this position when listening to the program from a component connected to the LINE terminals. TAPE 1/MD : For playback with a cassette deck or MD recorder connected to TAPE 1/MD terminals.
6 BALANCE control
Should normally be left in the center position. Adjust balance if the sound is louder from one of the speakers. If the right side is louder, turn toward the L (left) position and if the left side is louder, turn toward the R (right) position.
NOTE:
This control does not operate when the DIRECT button is in the on position.
30
A-307R, A-207R
7 DIRECT button/indicator
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 passing 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 off: The signal passes through the various frequency adjusting circuits.
0 BASS tone control
Use to adjust the low-frequency tone. The center position is the flat (normal) position. When turned to the right, low-frequency tones are emphasized; when turned to the left, low-frequency tones are de-emphasized.
NOTE:
This control does not operate when the DIRECT button is in the on position.
- SPEAKERS B (ON/OFF) button/indicator
Use this button to listen to the speaker system connected to SPEAKERS B terminals. ON : The indicator lights. Sound is heard from the speaker system. OFF : The indicator goes off. No sound is heard from the speaker system. Set to this position when listening with headphones.
8 LOUDNESS button/indicator
Use when listening at low volume levels. On : The indicator lights: Boosts low and high frequencies to give added punch to playback even at a low volume level. Off : The indicator goes off: Should normally be left in this position.
NOTE:
This button does not operate when the DIRECT button is in the on position.
= PHONES jack
When using headphones, insert the plug into this jack.
NOTE:
The speakers continue to output sound even when headphones are plugged into this jack. To mute the sound from the speakers, press the SPEAKERS button to OFF.
9 TREBLE tone control
Use to adjust the high-frequency tone. The center position is the flat (normal) position. When turned to the right, highfrequency tones are emphasized; when turned to the left, highfrequency tones are de-emphasized.
~ SPEAKERS A (ON/OFF) button/indicator
Use this button to listen to the speaker system connected to SPEAKERS A terminals. ON : The indicator lights. Sound is heard from the speaker system. OFF : The indicator goes off. No sound is heard from the speaker system. Set to this position when listening with headphones.
NOTE:
This control does not operate when the DIRECT button is in the on position.
