PROFESSIONAL SOUND SYSTEM
A professional sound system is a system that encloses a closed microphone, signal processor, amplifier, speakers, and recordings controlled by a mixed console to make the sound clear, loud, and clear to the human ear, and distributes their sound over larger or more remote spaces. In most cases, this system is used to improve or modify electronic effects, such as echoes.
The sound system of a rock concert in a stadium is very complex, and sound engineers and technicians use it to make tens of thousands of watts of amplifiers, multiple arrays of speakers, hundreds of microphones, live sound mixing, and signal processing. It can also be as simple as a public addressing (PA) system, for example, a 100-watt amplifier for a singer playing in a small coffee room consists of a single microphone connected to a speaker. In either case, these systems distribute the sound louder, or more.
