Hi,

like the bass boost circuit you can include BSC correction in
the power amplifier feeback loop, in this case by adding a
resistor-capacitor in parallel with the gain setting resistor,
in the same way as shown in you circuit. There is no need
for another op-amp for BSC, but if one is already there.....

Hi,

yes, I'll probably only use one chip (LM1875) and use those speakers at home.
My initial idea, that battery powered Class-D version, I'll probably realize it a bit later.

time to start doing some more practical work now! 🙂
I owe you for the many times you pointed me in the right direction!

Cheers,
Dominique
