Hi , this is a general question about amplifier :

When changing the output of any amplifier , there is always a "pot" to
adjust the bias DC of the driver .

Is there any procedure to do this adjustment ?

Thanks...

I found that the low end amplifiers do not have any adjustments for the
output DC zero set, or bias current.

Use an oscilloscope and adjust just until the zero-cross distortion
dissapears.
