What is an amplifier?
Power amplifier, abbreviated as power amplifier, generally refers to one of the most basic equipment in audio systems, commonly known as "amplifier". Its task is to amplify weak electrical signals from a signal source (in professional audio systems, from a mixing station) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification.The function of a power amplifier is to amplify weak signals from the sound source or preamplifier, pushing the speaker to play. A good sound system amplifier plays an indispensable role.
Power amplifiers are the largest family of various audio equipment, mainly used to amplify the weak signal input from the sound source equipment and generate enough current to drive the speaker for sound reproduction. Due to consideration of power, impedance, distortion, dynamics, and different usage ranges and control adjustment functions, different power amplifiers also have different internal signal processing, circuit design, and production processes.
