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.
For comfortable listening with headphones an audio signal of about 1 volt amplitude is desirable, so that an amplifier with a gain of about 100 times is needed.
