A power amplifier amplifies voltage. Its primary function is to take an input signal, typically a low-level voltage signal, and increase the amplitude (voltage) of that signal to a level that can drive a load, such as speakers or headphones, with sufficient power. This amplified voltage signal is what powers the transducers (speakers or headphones)
