DMX, also known as Digital Multiplex, is a communication protocol used in the entertainment industry to control lighting, sound, and special effects. It allows for the seamless synchronization of multiple devices, such as stage lights and audio equipment, through a single control source. Developed in the 1980s, DMX has become the standard for controlling complex lighting and audio setups in concerts, theaters, and other live events. Its versatility and reliability make it an essential tool for creating dynamic and immersive experiences for audiences.
