Amplifier
What is an "amplifier"?
An amplifier is an electronic device that increases the strength of an audio or electrical signal. It takes a weak input signal and boosts it to a higher level, which can then be sent to speakers, headphones, or other equipment. In audio systems, amplifiers enhance the sound signal to ensure it is loud enough and clear enough for listening. They come in various types, including those for home audio systems, musical instruments, and professional sound setups, each designed to meet specific needs and performance requirements.
