Someone lent me a subwoofer (Energy XL-S10). It worked fine at his location, no hum I could hear. I then brought it home. (this happened within the same day.)
First, I had it connected to my system and plugged it to the power bar (off position) which my CD player and receiver are using (nothing else). Then, I switched on the power bar (both CD player and receiver are off). A loud hum came through my bookshelf speakers immediately. I switched off the power bar right away (hum stopped) and removed the subwoofer from the system. I then plugged the subwoofer alone to another power socket nearby. A hum came out. I tried other power sockets in different rooms, same hum. It baffled me completely.
After I removed the subwoofer from the system, I switched on the power bar, CD player and receiver and played a CD. Everything was fine. No hum.
What is the problem here? Is it the power socket? Is it the wiring at my home? How do I fix it?
Thanks in advance for your input.
