I know how the basics of a transformer works but I'd like to know how an audio iso transformer eliminate a buzz or a hum in a audio signal?
It doesn't do anything to affect that.But what about if the source is already dirty or noisy?
So if it's dirty to begin it will stay dirty?It doesn't do anything to affect that.
Yes. A transformer isolates signals. The inductance may reduce very, very high frequencies (out of the audio range), but will not affect the signal. If it did, it would be adding distortion by removing signal frequencies.So if it's dirty to begin it will stay dirty?
