The role of a power amplifier in a sound system is to increase the amplitude of the electrical audio signal to a level that can drive loudspeakers. The power amplifier takes a low-level audio signal from a source such as a preamplifier or audio mixer and amplifies it to a level that can produce audible sound from speakers. It ensures that the signal is strong enough to drive the speakers, providing sufficient power to reproduce the sound accurately and efficiently. A power amplifier also helps in minimizing distortion and maintaining audio clarity, enabling the sound system to deliver high-quality sound output.
