Service manual very complete and clear. It was very helpfull for my work.
This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.
Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!

2.2 PANEL FACILITIES
4 Crossover knob (CROSSOVER)
When using the subwoofer, set the upper frequency limit for the subwoofer (50 Hz to 200 Hz) so that it complements the output from your other speakers. When using the bass management features of an AV receiver, set to BYPASS ON in order to use the low-pass filter of the AV receiver for high quality sound.
5 Bypass switch (BYPASS)
When set to ON, the audio signal is routed directly to the woofer unit, bypassing the amplifierâs filter.
6 Phase switch (PHASE 0Âº /180Âº)
When set to 180Âº, the output phase becomes the reverse of the input signal, and when set to 0Âº, it is in the same phase as the input signal. â¢ Normally, the switch is set to 0Âº. But when the sound connection between the subwoofer and the left and right speakers sounds unnatural, try switching to 180Âº and set the switch in the position where the sound is natural. â¢ When using two or more subwoofers together, make sure that the phase switch of all of them are set to the same position.

Lights green when the power has been switched ON.
â¢ If you are planning on switching the unit OFF for a long period of time, make sure to check that the indicator light has gone out after switching OFF.
