Helpful?

Must produce the proper sound exactly, with no altercations. The sound has to be perfect with no distortion, as the music has already been made and these are simply designed to allow it to play louder through speakers, instead of too quiet to be appreciated properly.

An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 hertz to 20,000 hertz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain.
