Cerwin Vega AVS-Sub8 problem

Hi I just upgraded my receiver to a new Denon AVR-789 and in the process, picked up a USED CV AVS-Sub8 subwoofer.

After initial hookup of the system, everything worked fine. The sub received power and sounded pretty good (for an 8" sub anyway). I played it for about 45 minutes.

The next day I plugged in a DVD and the sub not longer works. It powers up fine (red power light comes on) however does not appear to be receiving the signal from the receiver. When receiving a signal the red power light turns green but now it just stays red. The receiver shows that it is outputting dolby digital audio and the subwoofer light on the receiver display is lit so I am pretty sure the receiver isn't the problem. I've tried different co-ax cables and plugged into both the left and right inputs on the sub. I've even tried unplugging one of my front speakers and attaching these leads to the CV (it has both coax and speaker wire terminals). Nothing seems to work.

I'm a subwoofer newbie. Anyone have any thoughts as to what could be going wrong?

Thanks in advance.

Is the sub output on the receiver turned on. If the receiver is set for full range speakers there will be no output on the LFE channel.

Yes it should be outputting. It was working yesterday and I made no changes to the receiver. But just to be sure I went into the options and checked to make sure sub output is on. Still nothing.

I'd say check any fuses, though I wouldn't think you'd have a light on the sub, but it's worth a try. The other culprit could be simply be a loose wire from the subs internal amp to the driver, or something like that. That's easy to check if you just remove the driver cone (carefully of course, and visually inspect internal wiring. Make sure the power is off of course.

I would bet the answer is in the owners manual for the Denon. You say you hooked up a DVD player and now it dosn't work. I bet there are separate bass managment settings for different inputs.

If the original poster using the multi-channel inputs this is most likely the correct answer.

I the DVD player hooked up digitally or analog? If analog how many cables?
