power amp
Drives the speakers
A power amp is the component in an audio system that takes a weak signal and amplifies it enough to drive speakers.
It's distinguished from a preamp, which handles initial signal processing and volume control.
In guitar rigs and home stereos, the power amp does the heavy lifting: The power amp pushes 200 watts per channel.
