Witam Sprzęt się włącza przekaźniki się załączają, ale w głośnikach słuchać tylko buczenie Przełączając na poszczególne wejścia tylko buczy na wszystkich wyjściach Po rozkręceniu pomierzyłem napięcia na stabilizatorach i są ok. Co zauważyłem dosyć szybko nagrzewa się radiator końcówek mocy bez żadnego obciążenia stan spoczynkowy też sprawdziłem na wszystkich kanałach? Pomierzyłem także selektor wejść napięcia dochodzą do układów +15V i -15V Na panelu przednim wszystko ładnie działa oprócz wyboru speakers jest do wyboru A+B A, B Nie przełącza załączone jest tylko A Może macie jakieś pomysły

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.
Reading should

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.

5. PCB PARTS LIST
NOTES:
• 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%).

6. ADJUSTMENT
6.1 IDLE CURRENT ADJUSTMENT
• CAUTION : Heatsink's DC level is equal to +B or -B.
Don't touch them or you will be electricary shocked.
1. Decrease the level of the Adjustment Variable resistors (VR) for the channel to be adjusted. ( Turn counterclockwise.)
2. Set the power switch to ON.
+4mV
3. Connect the DC voltmeter as shown below and adjust VRs in step No. order so that voltages become 16mV –0mV .
4. Ages for seven minutes.
5. Readjust in step No. order so that the voltages become 11.5mV ± 1mV (10.5 to 12.5mV). Adjustment is completed.

NOTES:
• 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%).

4 DSP MODE button
Press repeatedly to select a DSP sound mode. (HALL 1,
HALL 2, JAZZ, DANCE, THEATER 1, or THEATER 2). Use
these modes to produce surround sound from standard (two
channel) stereo sources and create different listening
environments.

~ EXTERNAL DECODER IN button
Use to hook up an external component that can decode
other types of signals and input them into the receiver.
! DIRECT button
Switches direct playback on or off. Use to bypass the tone
controls and channel level for the most accurate
reproduction of a program source. It will automatically put
the receiver in the STEREO mode for that function.

Audio Components Connections
Before making or changing the connections, switch off the power and disconnect the power cord from the AC outlet.
To begin set up connect your audio components to the jacks as shown below. These are all analog connections and your analog audio
components (turntable, cassette deck) use these jacks. Remember that for components you want to record with you need to hook up
four plugs (a set of stereo ins and a set of stereo outs), but for components that only play (like a turntable) you only need to hook up
one set of stereo plugs (two plugs). To use DTS surround sound features you must hook up your digital components to the digital
inputs but it is also a good idea to hook up your digital components to analog audio jacks. If you want to record to/from digital
components (like an MD) to/from analog components you must hook up your digital equipment with these analog connections.
The arrows indicate the direction of the audio signal.
The illustration is not applicable to the UK model.
