I have a strange problem when I attach a Panasonic home DAT (3800 and 3700 both), analog out via XLR to RCA in on my Rotel RA-985BX integrated amp. I have used different cables and tried switching power plug outlets for each.
The hum is not on DAT playback, but is actually only noticeable when I have the selector on the amp to play my cable box for TV sound. The hum is very pronounced. When I disconnect the 3700's output cables, the hum goes away. The hum occurs if the 3700 is on or off, doesn't matter.
Can anyone provide some insight in what is causing the issue or how I can alleviate the problem?
Thanks in advance.
