The function of the amplifier is to amplify the weak signal from the source or preamplifier and push the speaker to sound. The role of a good sound system amplifier is indispensable. The amplifier can be said to be the largest family of all kinds of audio equipment. Its function is mainly to amplify the weak signal input by the sound source equipment, and generate enough current to push the speaker to reproduce the sound. Due to power, impedance, distortion, dynamics, and different ranges of use and control adjustments, different amplifiers have different internal signal processing, circuit design, and manufacturing processes. As shown in the figure, the circuit design of the amplifier circuit is shown.
