Thread: Amp Headroom vs Efficiency (and quick question about dyno vids)

    Re: Amp Headroom vs Efficiency (and quick question about dyno vids)

    As I understand it, THD and Noise will be higher at low volume because the noise is generally at a non-changing level and is therefore lower relative to full output. Those are both relative measurements.

    Yeah but the distortion in a switching amp should be higher as the switching goes towards 1 pulse.

    in a class D the noise should probably be lower than a class-AB or class-A?
