A professional speaker, abbreviated as a pro speaker, is an activity as well as a category of high-end, studio-grade audio equipment. Sound recording, sound reinforcement system setup, and audio mixing, as well as studio music production, are typically performed by trained sound engineers, audio engineers, record producers, and audio technicians who work in live event support and recording using mixing consoles, recording equipment, and sound reinforcement systems. Professional audio is distinguished from consumer or home-oriented audio, which is designed for listening in a non-commercial setting.
