Humming sub.


I tried to teach it the words to no avail.
Velodyne ULD 15, low hum when powered up, can't hear it when music is playing. It does not vary with volume on the servo controller amp.
Any guesses what it might be? I tried different cables and checked connections.

I have this sub also, slight level of hum; I was told this hum results from the servo circuit and cannot be eliminated.
