Humm and background noise
I get an awful hummm and background noise when I try
recording, following your instructions to a "T". It
turned out that the ground wire (the round plug that is part of
the three-pronged plug), when plugged into the wall or outlet,
was making the hum...
You've got the "A/C Humm"!
I've encountered this problem in a different form. It has happened to me when I tried to playback music from my laptop thru some of the old hilton sets (the 200?). The fix is to use a three-to-two prong adaptor on the laptop power cord.
