Keep cranking gain till distortion on O scope??

[DIGIDIGIBOMBO 10+ year member]

Hi, is it good to keep turning the gain up just before the distorted sine wave shows on the O scope? But even though the signal is clean we might be way overpowering the speakers, so this is another reason for hearng distortion right? Then what is the best method, using the DMM? Thx

find out where your HU clips first then turn it back until there's no clipping, that will be MUV(maximum usable volume)

then set your gain on your amp from there using the same method.

1.) use DMM/Oscope.

2.) mark this point.

3.) adjust using ear as desired.

you are correct. the maximum undistorted power may not actually be the best setting. people who go with the DMM method can use the HU or other volume controls to adjust the levels.
