Hi,
I am getting 60hz hum on one channel from the pass-through interconnects on my A30 Pro. The hum is only there when the A30 is on and engaged, and it happens only in the output directly adjacent to the mains input. If I switch the output lines, the hum appears on the other channel, the one that is now adjacent to the mains. The hum is not influenced by the volume control (which would be disconnected from the pass-through when the amp is on).
How to remove the hum? Should I be thinking about isolating outside the amp, so maybe wrapping the mains connect in copper foil? Or inside the amp? doing?
Any ideas?
Thanks!
Stef
