Re: Amps getting hot even at low volume
The amp doesn't work any harder making 200w with the gains high or making 200w with the gain set to min. That's not how it works.
Your issue is that you are running big Class A/B amps at low power where they are not as efficient. They'll usually get hotter at low volume than at high. 1/3 power is used as a torture test for A/B amps for just that reason.

Never underestimate the power of stupid people in large numbers.
Life's tough...it's even tougher when you're stupid.
