Amp Humming Sound

[mbarber25 29]

Ok so today i was resetting the gain on my Sundown Audio SAZ-2000D. I was using a 50hz tone using a dmm. I realized that once the gain was turned up to a certain point it started to make a weird humming sound. I could hear it from inside of the amp on the side closest to where the settings are.

Any ideas of what it may be?

The 50hz tone I have repeats in 10 second intervals. I can only hear this humming sound from the amp during the 10 seconds.

And yes I'm not hearing the noise coming from the speakers inside.

Why does the amp only make this sound when the gain reaches a certain point?
