I have a KLH Model R 3000M stereo receiver. As I raise the speaker volume from -63 dB to -50 dB, the speaker safety light kicks on and the speakers go dead. I used to be a high end stereo technician so I believe that a schematic/service manual is what I need. Can you help me?

I figured out the problem.  After you set the individual channel volume for each speaker you need to push the test button on the remote and this will lock in the settings.  Thanks.

SOURCE: klh r7000 no sound

Like I wrote, I had a similar problem with popping and then no audio for an extended period of time. I found the solution on another site, http://dexsoft.com/blog/?p=15

Apparently the solder joints are weak, and just as the blog described when I opened up the receiver I saw the same scorch marks from overheating. Just as the blog described, I added solder to each of the joints in the photo and have had no problem ever since.

I am no solder expert, this is my 2nd time, but all I did is build up each of the joints and I have been listening to music, playing movies in surround sound with no problems, no popping for the last 2 weeks.

SOURCE: Trying to hook up Zone B stereo speakers in two additional rooms.

The infrared mentioned by the manual is most likely an extension possibility to use the remote control in each room, forget that part.
What you need to do is quite simpel, after connecting all speakers, you should indicate in the setup menu of each zone which speakers are connected and do as follows:
in main room select 5.1 setup, for the other zone select only the left and right front speakers.
Your EXTRA SP indicates the extra speakers for 7.1 setup and when set to zone B it recognises only 1 speaker.

So read carefully the manual how to connect Zone 2 speakers and connect that way, than carefully walk through the setup menu to setup the zone 2 correctly.

SOURCE: Subwoofer does not kick in during stereo mode with front speakers

There should be an adjustment in setup that for 2 channel sources, you may have to enable the subwoofer output. Or alternatively, if the subwoofer output for 2 channel sources is in fact enabled, then increase the crossover frequency for the sub.

SOURCE: Have Onkyo TX-NR808 receiver. Not

The problem is the audio output ic's, one or more channels has developed a short causing the safety shutdown to engage. The only solution is take it back where it was purchased and since it is under warranty it should be repaired free of charge if not a possible exchange.
