An audio power amplifier is designed to amplify low-power audio signals to a level suitable for driving speakers, typically in the frequency range of 20 Hz to 20 kHz, which is the audible range for humans. In contrast, a radio power amplifier amplifies radio frequency (RF) signals, which are much higher in frequency, to levels necessary for transmission over long distances, often used in communication systems like broadcasting and telecommunications. The main difference lies in the frequency range they operate in and their specific application purposes.
