So far DC is decoupled from input an no nonlinear componet like diode and no feedback. How can this circuit stable, so far it just follows the AC after some time and generating rectangle

If i understand correctly he means "automatic power supply magnitude switcher/selector for subwoofer with time and sensitivity correction " ? Can any correct me if i'm wrong.

my german suppose to be good enough ;-) my translation, "Subwoofer poweron or automatic source selection by level. With sensetivity regulation..."

Ahora si, now there is a peak detector diode and it seems to work. Sensetivity is around 5mV. I am not sure, but wouldn't it be engouh to just have a peakdetector directly connected to the loudspeaker and forget both opamps?
