Moved Onkyo 606 and no more sub output

[jkreef]

I have a Onkyo TX-SR606 and an Acoustech H-100 Cinema Series subwoofer that have been working well for the last few years (never had a problem).

Last week, I moved the receiver to a different shelf and for some reason my subwoofer has stopped working. I didn't change any configuration, but for the life of me, I can't figure out why this has occurred.

The cable run to the subwoofer barely moved. It's a big thick Monster RCA cable. The receiver only physically moved 12 inches. Things I've done:

- Verified the front speakers were not set to full band and the subwoofer was Yes in the Onkyo speaker config
- Verified the subwoofer cable was plugged into pre-out subwoofer jack (and obviously the sub in jack on the subwoofer).
- Disconnected and reseated both subwoofer and receiver cables
- Re-ran Audyssey auto speaker setup. It didn't detect the subwoofer.

I've always left the H100 power switch in the Auto/Standby position. The light is red when off and used to turn green when it detected the signal. I've tried turning it to the on position, but I still get no sound from it.

I get sound from the other 7 speakers (when playing a 7.1 source), but the subwoofer remains muted (likewise, the Audyssey setup produces the tones in each speaker except the sub).

I've looked through the manual of both of the Onkyo and the Acoustech, read every troubleshooting step and searched many forums, to no avail.

Does anyone have any steps they could recommend to a noob like me to track down where the problem is? I feel it's most likely a configuration problem, and not a hardware problem, but I'd like to rule that out too. I'm not sure what else I can do to verify the sub works, and the receiver is outputting the pre-out signal.

Thanks in advance for any help you can provide.

Welcome to the forum!

The first thing that I'd try (after doing what you've already done) is use a different cable to connect the receiver to the sub. You never know, there could be a bad connection in the cable at one of the ends, and moving it around just made it show up.

If that doesn't work, you can see if the sub is still working (you didn't move it, though, correct?) by connecting another source to it, such as an iPod. We can walk through that process if it comes to that.

I'd try a different cable first, though.

OK, I feel like an idiot now.

I hadn't moved the subwoofer or the subwoofer cable. I didn't have any long RCA cables to use in it's place, so I just moved the sub next to the receiver and grabbed a really cheap generic red/white interconnect cable that was laying around and plugged it in. Wouldn't you know, it worked.

Although I knew this was the first thing to do, I really didn't think it was the cable. All my cables are from BlueJeans except this subwoofer cable which was a really thick Monster one I found for 75% off

I can't believe I wasted so much time on this problem when I should have done the easiest thing first (and definitely before posting). Sorry for wasting your time and Thank You!

I'm glad that it worked!

I'm not surprised. People on these forums don't like Monster because of their deplorable ethics, but say their cables are good put over priced. My experience is that they are lousy overpriced cables. You just found out the hard way.

That was no waste of our time. When weird things happen, sometimes one of the first instincts is to ask someone.
