The sound of the amplifier is distorted? Sound dye?

What is the distortion of the amplified music signal output from the power amplifier?
It means that the output of the device cannot fully reproduce the signal shape of the input end due to the circuit design defect of the power amplifier or the defect of the component parameter quality, resulting in waveform distortion or increase or decrease of signal components.

In other words, there is no perfect amplification of the audio input signal. Under normal conditions without distortion, the amplitude is only amplified but the waveform remains unchanged. Distortion means that the waveform has changed.

What is harmonic distortion?

Refers to that because the power amplifier is not perfect, the output signal not only contains the amplified input audio components, but also produces some frequency components (harmonics) that are 2 times, 3 times, or even higher than the original signal, so that the output waveform is not the original Look like. This kind of distortion caused by harmonics is called harmonic distortion.
What is crossover distortion?

A distortion phenomenon peculiar to Class B amplifiers is caused by the amplifier characteristics of the circuit. The reason for this distortion is that the positive and negative half cycles of the signal are amplified by two different sets of devices (power amplifier tubes, etc.), and the waveforms of the positive and negative half cycles cannot be connected completely smoothly.
Tone dye

The opposite of high fidelity, that is, the output sound of the power amplifier is stained with some characteristics that the input music signal itself does not, such as singing in the bathroom, the kind of sound produced is a typical sound dye phenomenon. Some components are added (or reduced) in the reproduced signal, which is the so-called sound staining phenomenon, which of course is also a kind of distortion.
