power amplifier
Strengthens audio signals
A power amplifier is an electronic device that takes a weak audio or radio signal and increases its strength enough to drive speakers, antennas, or other output devices.
Unlike preamplifiers, which boost signals just enough for processing, power amplifiers are designed to deliver substantial wattage.
They're essential components in audio systems, broadcast transmitters, and wireless communications.
The power amplifier in his home theater system could drive even the most demanding speakers.
