In solid state amps there is an adjustment commonly called "bias". It does not set a level of current, as in a tube amp, but it equalizes current from the complementary set of output transistors so that when there is no signal being amplified the amp output is nearly zero volts. If the amp puts out voltage unrelated to the audio signal, the loudspeaker voice coil is heated, and the cone is pushed away from its rest position so that its available range of motion is reduced.
Please explain
Is there a simple explanation available for "Bias" in relation to amps (especially SS if they are different). I notice posts refering to adjusting Bias - why? what is accomplished? Is there perhaps a web location that explains a lot of the basics that would be useful to those still learning?
I've looked thru the archives but didn't notice aanything that answered my question (I admit I could have missed it).
I thank all of you for your help
