The place I'm interning at right now has these monitors and I can hear the radio on them. It's a little annoying because you think you have voices in your head.

Anyways... how would one go about getting rid of it?
Notes:
A- The facility is near the CN tower, which broadcasts many signals.
B- I tried unplugging the audio cable into the speaker, so the problem's not there.
C- Active-powered speakers, as the name suggests.

Sounds like your speaker may have an internal grounding problem. see if when you move them around there is any change. Try different rooms too. Mark

I think it happens in all the rooms.

I know ... bring 'em here to Waterloo ... if the problem goes away, so can you and leave the speakers behind!

Actually you could test them here and if there is still a problem, the Tannoy D.C. is 2 blocks from here...
