I am driving a 12W audio amp module from a PC soundcard and would like to fit an _adjustable_ clipping indicator.
Would like to keep the circuit as simple as possible. Not a hi-fi application. It's just because the PA speaker is in another room and I cannot hear if distortion occurs.
What are the pro's and cons of the circuits below? Any other suggestions?
The next is simple, but not adjustable, and would need to be modified for a 12VDC supply.
Thnak you for any advice.
