Power Amplifier

A power amplifier is a device that increases the strength of an electrical audio signal so it can drive speakers loudly and clearly. It takes a small input signal, like from a microphone or audio source, and boosts its power without changing the original sound quality. Think of it as a translator that takes a whisper and makes it loud enough for everyone to hear. Power amplifiers are essential in sound systems for concerts, home theaters, and audio equipment, ensuring the audio output is powerful and clear enough to fill a space.
