field mixer

A field mixer is a device used in radio and television broadcasting to combine multiple audio and video signals into a single, seamless output. Think of it like a control panel that allows operators to select, adjust, and blend different sources—such as cameras, microphones, or media feeds—ensuring smooth transitions and consistent quality. It helps create polished broadcasts by managing the timing, position, and blending of all incoming signals. Essentially, a field mixer acts as a central hub for organizing and controlling all the visual and audio elements in a production.
