Its job is to take a line-level signal and make it loud enough to fill a room or a venue with sound.
Power amps can feature one, two, or more channels. For example, a mono power amp would have one channel, and a stereo power amp would have two channels.
Its function is mainly to amplify the weaker signal input from the audio equipment and generate a large enough current to drive the speaker to reproduce the sound.
