What Is a Stereo Amplifier?
A stereo amplifier is a device that increases an audio signal so that it can be heard through a speaker. While this would seem like a basic function of any audio equipment, the power required to produce a series of sounds hardly takes any energy at all. Without a stereo amplifier, the music from a radio may sound like a distant whisper that many humans would not be able to hear at all. To generate that sound through a speaker, a much greater source of power is required, and that sudden surge of power is likely to distort the acoustics that are produced. A stereo amplifier increases both the power generated towards the output and the quality of the sound being replicated at the same time, allowing consumers to comfortably hear music or any recorded audio through speakers.
