A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.

Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.

Well.. I'd searched for this manual and although I found many copies online I was pleased to find your website with a well balanced pricing system and easy to search and follow links. That together with the very quick response time was just what I was looking for.. being a very impatient tech.. ;-) I had the service manual in front of me within a short time.
Bookmarked.. and you can bet I will always come here first for my service & user manuals..
best regards

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.

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.
