A power amplifier (PA) is an electronic device used to amplify audio signals. It boosts the low - power input audio signals to a higher power level to drive speakers or other loads. Power amplifiers play a crucial role in audio systems as they increase the amplitude of audio signals, enabling them to produce sufficient sound from speakers.

A power amplifier, commonly known as an "amplifier", its function is to amplify the weak signals from the sound source or pre-amplifier to drive the speakers to produce sound. In a good sound system, the role of the power amplifier is indispensable. The power amplifier is the most basic device in a sound system. Its task is to amplify the weak electrical signals from the signal source (in a professional sound system, from the mixer) to drive the speakers to produce sound.
