According to Claude, the attenuation stage is before the power amp stage. Does that mean worse SNR whether the volume is controlled using the volume control or via the input?
(Ignoring the additional quantization issue with a scaled digital input.)
- kevin_thibedeau 2y agoClass D doesn't have any attenuation. This is a big factor in their greater efficiency.
- dreamcompiler 2y agoYou could put the attenuation stage after the power amp stage but it would require big beefy resistors that could absorb a lot of power. They'd get hot and the whole thing would be very inefficient. But hey, very low distortion.
