Service Manual that I received was very helpful to me. Thank you.
;
The manual is well organized and is easy to read. The chapters are following normal way to proceed.
;
This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

NOTE: � 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.
Bass mode switch (BASS MODE) MUSIC: The characteristic frequencies become flat. Recommended for music sources. CINEMA: Low frequencies are emphasized. Recommended for sources that require strong bass. Phase switch (PHASE 0º /180º) When set to 180º, the output phase becomes the reverse of the input signal, and when set to 0º, it is in the same phase as the input signal. � Normally, the switch is set to 0º. But when the sound connection between the subwoofer and the left and right speakers sounds unnatural, try switching to 180º and set the switch in the position where the sound is natural. � When using two or more subwoofers together, make sure that the phase switch of all of them are set to the same position.
