Power Amplifier

An audio power amplifier or power amp is an electronic amplifier that amplifies low-power electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is high enough for driving loudspeakers or headphones. Audio power amplifiers are found in all manner of sound systems including sound reinforcement , public address and home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers. The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification of the signal this is particularly associated with record turntable signals, microphone signals and electric instrument signals from pickups, such as the electric guitar and electric bass , equalization e. The inputs can also be any number of audio sources like record players , CD players , digital audio players and cassette players. Most audio power amplifiers require these low-level inputs, which are line level. While the input signal to an audio power amplifier, such as the signal from an electric guitar, may measure only a few hundred microwatts , its output may be a few watts for small consumer electronics devices, such as clock radios , tens or hundreds of watts for a home stereo system , several thousand watts for a nightclub 's sound system or tens of thousands of watts for a large rock concert sound reinforcement system.
