It is an very good and clear scanned service manual.
Easy to order the manual. Good quality and fast delivery.
The Service Manual for Sansui AU-9500 was very helpfull, in complete and in good printable condition.
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,
The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.
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.
1 Power Indicator (POWER ON)
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.
