Audio amplifiers use Class-AB because a Class-B circuit has crossover distortion that sounds horrible.macs_lex said:so it wouldn't be possible for a class B amplifier? thank you so much for the reply!
We don't use a class-B amplifier because it has horrible crossover distortion. Instead we use a class-AB amplifier.macs_lex said:Do you have a pre-amplifier circuit than can be connected to a class b power amplifier?thanks a lot!
I tried to simulate this circuit on pspicepauloynski said:As posted above, class-B amplifiers sound horribly. However, they are used in some PA systems. There is one exception that comes to my mind: the current dumping technology developed by Quad uses a true class-B output and a small class-A driver which is used to drive small amplitude signals, resulting in a very good quality amp.
It is not an easy made project so, again as posted above, try using a LM3886 or similar and avoid having a headache.
Which circuit? Are you refering to the "dumping-amplifier-100w", which seems to be an ancient Elektor circuit?I tried to simulate this circuit on pspice
it doesn't work at all
