What is a macro in the context of AV technology?

In the context of AV technology, a macro refers to a set or sequence of functions that can be activated by a single button press. This allows for complex operations to be executed quickly and efficiently. For example, a macro might be programmed to turn on all necessary equipment for a presentation, adjust the lighting, and switch the inputs on a mixer with just one action. By streamlining these processes, macros enhance user experience and reduce the potential for errors during events.

The other options relate to different aspects of audio-visual technology: an audio signal refers to sound transmission, video compression involves reducing file sizes for video files, and a design standard for lighting pertains to guidelines or best practices in lighting design. None of these definitions align with the operational nature of a macro in AV systems.
