Just got some self-amplified Swan D1080's that are emitting a pretty bad buzz when plugged in. (Figure amplifier's the best forum, since it's probably coming from their internal amp.)
I'm somewhat electrically able and I wonder if I can get them working. Here are some clues:
Any idea? What should I look for if I take them apart?
I'm somewhat electrically able and I wonder if I can get them working. Here are some clues:
- This isn't pure noise, it seems to pick up some radio and other static.
- The volume control does NOT change the volume of the buzz
- This only happens with audio cables plugged into the inputs. Buzz is only 1/10th as loud without any cables going into the RCA input. Having that cable plugged into a source vs. not doesn't affect the noise. And this happens with any pair of cables.
- They don't have a grounded power cable.
