Negative feedback in audio amplifiers: Why there is no ...

What is negative feedback (NFB)? “Feedback is an arrangement where an amplifier is made to respond to its own output signal in addition to the wanted input signal and any unwanted disturbances. When the response to an unwanted disturbance is smaller with feedback applied than without it, we call it negative feedback.”

I don't know exactly since when negative feedback in audio amplifiers has become the issue it currently is but several storylines converge. Storyline 1: TIM In 1970, Otala identified his infamous “Transient Intermodulation Distortion,” a fancily named manifestation of Slew Induced Distortion.

Over most of the audio range the feedback loop didn’t do much. Unsurprisingly those amplifiers sounded rather bad. In the public mind, feedback became associated with the sound of these early solid state amplifiers. Amplifier Feedback Actually Increases Bandwidth

Audiophile Myths About Amplifier Negative Feedback Debunked by Bruno Putzeys — July 18, 2020 Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in audio, and then only specifically in power amplifiers.

It's a 10W audio amp, not an op amp. Negative feedback is required to set the gain at a known, fixed value. "Fundamentally, all electronic devices (e.g. vacuum tubes, bipolar transistors, MOS transistors) exhibit some nonlinear behavior. Negative feedback corrects this by trading unused gain for higher linearity (lower distortion).

All About Audio Amplifiers Feedback is when a part of the output signal of an amplifier is fed back to the input. NEGATIVE FEEDBACK is when some of the output signal is fed back to the input in such a way as to PARTIALLY cancel the input signal.

4.4 Global Negative Feedback in a vacuum tube amplifier. Push-pull stages are able to reduce harmonic distortions, specifically second order distortions, produced in the stage itself. When an input stage has a single-ended configuration and operates in non-linear areas, it produces distortions. If the distorted pre-amplified signal is given to ...

"A negative feedback amplifier, or more commonly simply a feedback amplifier, is an amplifier which uses a negative feedback network, generally for improving performance (gain stability, linearity, frequency response etc.). Feedback can be negative or positive, but must be negative for overall stability of the system.
