In Reply to: Re: Power Consumption in Class A Solid State Amps.....Help needed. posted by rmzidann on April 21, 2007 at 18:16:49:
A Class A amplifier consumes its'entire rated power at idle because both the positive and negative rails are turned full on at idle and there is, therefore, no signal output since, for instance with a 10A Class A amp a + 10A and a - 10A output = 0. This is why a Class A amp has no crossover distortion since there is no crossover from + to - output i.e. both + and - rails are full on at idle. To produce an output signal the output of one rail, either + or - is lowered causing the opposite rail to output a similar voltge. I hope this has totally confused you, as it did me for quite a long time.Happy Listening !
