Paradigm Servo 15 picking up AM radio station


In my home theater rig, my Paradigm Servo 15v1 is picking up a local AM radio station. For those of you in the Chicago area, I finally figured out that it was AM, because I could make out the very distict voice of Doug Baffonne on AM 760, a local sports radio personality.

It isn't loud, and I can really only hear it if I put my ear next to the speaker, but it's annoying none the less. It also puts out a constant low level white noise, that again is only audioble with my ear next to the speaker. The sub has a function where it will automatically shut off when it doesn't detect a signal in a certain period of time. Because it is always getting a radio signal, it won't shut off unless I shut it off manually with the switch on the back.

I THINK the power cord I am using is shielded.

Any thoughts/suggestions?

Thanks for the responses guys. I think it is coming from the processor. The power cord that I am using on the processor is not shielded, so I may try removing that part of the equation by replacing it with a shielded PC and see what happens. I did try just disconnecting the sub interconnect cable, and it did go away, so I am thinking it has something to do with the processor (which has a tuner built into it by the way). The sub interconnect cable is a Monster cable that does have shielding (what kind of shielding I am not sure). I will also try repositioning cables as well and see what happens.
Thanks for all of your responses. I finally bit the bullet and took the sub in for service to get it checked out, and it turned out I had a loose ground wire connection inside the unit. I bought the sub here in AG, so it probably got jarred loose in shipping, but who knows? This has fixed the problem. Turned out to be a $90 fix, so no big deal.
