About Audio Amplifier An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain. It is designed for intermittent duty, suitable for an equalized sub woofer system (for example using the ELF principle - see the Project Page for the info on this circuit).
