output transformer

TheFlayinDutchm · 11th January 2004, 05:26 AM

ahoy me hearties, I be new to these forums, have a couple of questions.

How will an output transformer affect the general quality of an amp? Will a real world transformer introduce much distortion, and if so, what orders, generally.

Also, is it wise to use the transformer as part of the output filer, for class d type applications?

For transformer coupled amps (single ended or push-pull) the transformer is perhaps the most important part for frequency response and linearity. Class D amps usually use a lowpass filter which involve simple inductors, not a transformer.

Yeah u can use the IRON CORE AUDIO OUTPUT TRANSFORMER in the place of Filter For CLASS_D AMPS
Because i have also used one.
