I was fooling around with my amp today, turning up the gain gradually, and I was getting excited, sub was pounding a lot harder, and it didnt sound like it was getting any muddier or sound like it was clipping. But then i noticed that once i disconnected the sub and played a tone, the amplifier itself was making a buzzing noise. So i turned back the gain and it went away.

I was wondering if this was some kind of built in clipping detector or something along those lines? Have you guys ever encountered something like this? Any info would be great, thanks guys.

No, not any type of built in "detector". It was probably the toroids inside the amplifier making noise. You were probably overloading the toroids due to the higher level of current running through them with the gain turned up. That or some of the windings are simply loose so as the power increased they were able to wiggle a little and cause a buzzing sound.

Alright thanks Impious, thought you might reply to this, you electrical genius you.
