2. Origin of the Term PA Speaker

The term "PA" stands for Public Address. PA systems emerged in the early 20th century, primarily to aid communication in large areas.

3. How PA Speakers Work

PA speakers operate by converting electrical signals into sound waves. The process begins when sound is captured through a microphone, converted into an electrical signal, and sent to an amplifier. The amplifier boosts this signal and directs it to the speakers, producing sound. This complex interplay ensures that speakers can effectively reach and engage audiences.
