I have JBL LSR308 active monitors with class D amplification inside.
How much can I safely set gain (a knob on the back plate, goes from 1-10) without running into significant class D distortion, be it audible or not? Of course this depends on the amps, but these speakers were around 650$ when I bought them new 5 years ago so obviously they don’t have especially high quality class D amps.
I keep my DAC feeding them at max volume (and obviously the source volume too) so then I have to keep the monitors at gain setting 5.5 at most, to not get too loud. I guess that’s fine considering the issue of distortion, I’m just interested where the margins go for when Class D starts distorting enough to matter.
