Audio Myths: Feedback Re-Entrant Distortion. Should We Worry?

There are many aspects of negative feedback in audio that are the subject of continued discussion. Jan Didden continues to debunk more Audio Myths. This article addresses re-entrant distortion. The idea is that, since negative feedback sends some of the distorted output signal back to the input, this already-distorted signal would only get more distorted by going through the nonlinear amplifier, over and over again.

Audio Myths: Feedback Cannot Fix What Has Already Happened

This article, originally published in The Audio Voice newsletter (#434), explores some practical experiments with Negative Feedback. "If I had a dollar for every time someone mentioned that negative feedback cannot work, because you cannot correct something after it happened, I would be a rich man," says Jan Didden.
