What is the primary function of an amplifier in an AV system?

The primary function of an amplifier in an AV (audio-visual) system is to increase the power of audio signals. Amplifiers take weak audio signals as inputs and boost them to a level sufficient to drive speakers, thereby improving sound quality and ensuring that audio can be heard clearly in a variety of environments. This amplification is essential for delivering audio effectively and achieving the desired volume levels without distortion.

Understanding that amplifiers serve as essential components in the audio chain helps clarify their role in connecting audio sources (like microphones or mixers) to speakers or other output devices. By boosting the signal strength, amplifiers ensure that the auditory experience is impactful, making them a critical part of any AV setup.
