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.

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 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

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.

CAUTION : Heatsinks' (Q323­Q326) DC level is equal to +B or ­B. Don't touch them or you will be electricary chocked. Connect the measuring instrument as Fig.6­1. (R415 or R416) Set VR301 and VR302 to minimum. Set the POWER switch to ON. 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. 1. 2. 3. 4.

7.2 CIRCUIT DESCRIPTION
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.

1 Main power ( -- OFF/ _ ON ) button
If the button is OFF (--), the power of the amplifier is shut off and the STANDBY/ON button on the amplifier does not function. Pressing the main power button will turn the amplifier ON (_).
