Hi there,

is there a way to test my sub with a multimeter? It played fine when I set up the new Onkyo SR 806 manually. I played some Jurassic Park to test the various surround modes (DTS, THX etc.) and it seemed fine. The next day I use Audyssey to set up the equalizer and it does not recognize the sub. No sound from it any more. Is there a way to test the sub, resistance or anything? The cable from receiver to sub has 0 resistance, which I believe is correct.

Thanks for your help.

look for a fuse that may be blown and replace if needed with correct rated fuse......also you didnt blow the circuit breaker?

I opened it up and found the fuse, but it looks and measures ok, 125 V 2.5A. Can't see any real burnt pieces on the board either. When I put my multimeter probe into the RCA "in", I can still hear it hum, which I think is the nine volt from the meter. I wonder whether there is anything in the Onkyo SR 806 set-up that I'm missing. I turned Odyssey off and set Subwoofer to yes, but still no test tone. Any other ideas?

Thanks again

To see if you are getting any sound at the sub, you could disconnect the RCA cable with the sub on, but turn down the sub's volume a little beforehand. Just to see if the sub amp is amplifying..You'll hear a loud hum from the cable being disconnected.


If the sub seems okay, then it must be a receiver issue of some sort.

Thanks for the tipp. When I pull the cable out, there is nothing. No hum or short spike. The only thing that indicates the sub being on is the green light.

I have the feeling I might have blown something when I cycled through the various surround sound modes like PLIIx and THX while T-Rex was screaming. Yet the fuse is not blown.

Any other ideas?

Thanks again

Do you have another sub you could hook up to your receiver to see if it works?

Thanks, crossiev.

Unfortunately not. But I have another receiver and I went to hook up the sub there and see whether I get a sound out of it there. Then looking at the back of the receiver I noticed 2 subwoofer options. That's when it dawned on me that I might actually have used the "analog in" instead of the "power out". Sure enough, I had it plugged in wrongly. Prior to the Audyssey run, I had changed the receiver position in the shelf as it was running rather hot and I wanted to give it more air. Thats when I must have plugged the sub in wrongly.

I feel foolish now, but your comment kept me working on it one more time and it is playing now.

Thanks again.

Thanks, duvetyne, I think I had set the multimeter on AC when I poked around with it, to generate some electric input but don't hold me to it. It hummed, though. But it's moot now as it is working.

Thanks again
