It's exactly a complete and very useful manual with all details what I needed. Thank you!I will come back whenever I need your manuals or schematics.

I searched EVERYWHERE looking for the manual/s on this "extinct" amp. Owner-Manuals.com made it available and for nearly nothing. Thanx to them, I can decipher the unknown cables and sort them out. Thanx, Owner-Manuals.com!!

Yes thank you i got the file i was after. There was a slight problem in my communication but it all worked out well.
A job well done.

Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

4 Diagnostic mode
This mode is only for servicing and checking the circuit design, and not open to users. When the STEREO/DIRECT key and TONE + key are both held pressed for 2 seconds in Standby mode, the power is turned on, and the number of times of each defect or Speaker relay off by abnormality detection is sequentially displayed on the FL display. Displayed items: � DC detection � Overload detection � Fan detection � Temperature detection Hold the STEREO/DIRECT key and TONE + key pressed for 2 seconds in Standby mode.

Protection Process List
Item Purpose Detection Method Process Turns muting on and speaker relay off, then turns off the power after 3 seconds. Warning Indication Remarks To detect amplifier damage (defect status) A process to DC protect speakers detection (for protection of connected external devices) To detect overloading (abnormal status) With lowload driving or a short circuit of the speaker terminals (for protection of the amplifier) Flashing "AMP ERR" for Once detected and turned 3 seconds. the power off, input a key Flash the standby LED never again. after the power off.
Detects when the DC_DET port becomes "L".
D
Turns muting on and Detects when the AMP_OL port speaker relay off, and becomes "L" (checks by interrupt). immediately turns off the power. Detect temperature more than 100°C. Turns muting on and speaker relay off. Rotate the fan None
AMP overload
Continue flasing with "OVERHEAT" Mute, relay and warning indications is leading hold.
Fan control
Protection function against a temperature rise at the heat sink
Detect temperature of 90 to 100°C. Rotate the fan Detect temperature of 74 to 90°C. Detect temperature of 69 to 74°C. A condition except the above. Rotate the fan Fan is leading hold Stop the fan Turns muting on and speaker relay off, then Flashing "FAN STOP" turns off the power after 3 for 3 seconds seconds. Turns 12V_TRG port to "L", then turns off the 12V output.
Mute off & relay on (normal mode)
E
Fan stop
To know that the rotating fan is forcibly stopped
Detects when the FAN_DET port becomes "L".
If the FAN_DET port becomes "H" within 3 seconds, the unit resets automatically. After the power off, the key input is possible once again. Only a fan that is assigned 12V TRIG is valid.Release the FL indication with the power on/off.
Detects when the 12V_DET port 12V trigger To detect the shortcircuit of 12V trigger circuit becomes "H".
