I just bought a used Vandersteen V2W sub and am having trouble getting it working with an Adcom GFA-880 pre-processor.
Here's what I've tried:
* running the Sub Output to both of the phased inputs (one at a time)
* Plugging the sub directly into the wall & into a Monster 3600 Power Switch
When I plug the sub in, I get a pop so I know the amp is coming on. When I run a test signal, I barely get any noise out of the sub, even when I turn it's gain control all the way up to 15dB and the processor's up to 10dB (both max settings).
I don't seem to be able to get any sound out of the sub on CDs/DVDs or TV.
I'm using a Monster sub cable which doesn't have a seperate ground which Vandersteen suggests, but I find hard to believe that accounts for no sound. I did swap the sub cable in as an interconnect to one of my front channels and it works fine, so I think I can safely rule out a bad cable.
Any suggestions on how to narrow it down to either the sub or the processor? Is it safe to hook the sub input up to a front output, which I know works to verify the sub functions?
Thanks for any suggestions, as the lack of bass is quite a disappointment so far.
