[QUOTE="thylantyr, post: 2277244, member: 560358"] There's some comedy to this. To explain. An amplifier has gain, and it's fixed gain as shown on that schematic I linked eariler. But, amplifiers with gain knobs are not really gain adjustments, they are input attenuators to reduce the signal, gain remains fixed in spite that the amplifier is labed as 'gain'. ... lol ... You probably know this already ... By adding input attenuators you are essentially making a 'gain control' even though it's not the real thing. This can help relieve the problem, but if you want to solve the problem at the root level, you change the amplifier gain, that feedback resistor I talked about. This method will give you the [B]best[/B] performance because a high gain amplifier with attenuated input is [B]still[/B] in 'high gain mode' which can amplify noise present, usually noise from the amplifier itself can be annoying.
