DISTORTION MEASUREMENT IN AUDIO AMPLIFIERS
https://renardson-audio.com/distortiontest.pdf
DISTORTION MEASUREMENT IN AUDIO AMPLIFIERS. By Michael Renardson. SUMMARY The requirements for the measurement of non-linear distortion in audio power amplifiers are examined. The limitations of conventional measurement methods are discussed and several improved test methods described in which complex test signals could be used.
What is Distortion in Amplifier? Definition, types of ...
https://electronicscoach.com/distortion-in-amplifier.html
Definition: Distortion in Amplifier basically implies the variation in the waveform received at the output with respect to the applied input. The unwanted alterations generated during amplification is known as distortion. A pure signal always has a single frequency component where voltage varies positive and negative by an equal amount.

How Do We Perceive Car Audio Amplifier Distortion? In the case of harmonic distortion, this typically manifests itself as adding an amount of “brightness” or “harshness” to the amplifier since it creates high-frequency content where none originally existed. Harmonic distortion reduces the clarity and realism of the music you are enjoying.
Audio Distortion: Finding the Source and Clearing the Air ...

Audio distortion can occur for a number of reasons. Common reasons include: A microphone or sound source, like a computer, is overloaded with sound . For example, the microphone can’t handle the volume level which it’s detecting and thus distorts the sound that it’s sending into the sound system.

If the power amp requires more than 2Vrms to hit rated power and the preamp can't deliver it, then the result will be a clipped preamp signal amplified by the power amplifier which will cause audible distortion and/or compression.
A DIY approach to distortion measurements for audio amplifiers

Essentially you can discover the harmonic distortion signature and the noise floor of your amplifier. As forum member XRK971 details in the first post in the thread, all that is needed at the most basic level is a decent internal PC sound card or external USB Audio interface, some free software, three resistors and some wire.
Amplifier Crossover Distortion - Benchmark Media Systems
https://benchmarkmedia.com/blogs/application_notes/131424519-amplifier-crossover-distortion
Most audio power amplifiers suffer from a defect known as "crossover distortion". This distortion is particularly troublesome at low output levels. At low power levels, the crossover distortion can rise to a high percentage of the output level and become the dominant source of distortion. The Important First Watt
