AV Terminology

Every discipline has a unique lexicon, and it’s my honor to bring you my short list of AV terminology – guaranteed to make you a better negotiator,
a more informed purchaser, and THE ROCK STAR PRODUCER you are meant to be.

General Terms

“PLAYBACK” – video or audio files being run (best case scenario) on a separate machine.

“MACHINE” – a word often used to indicate a laptop or playback device.

“TALENT” – an ingratiating term for anyone who is onstage as a part of a program (presenter, etc.)

Audio

“LAVALIERE” – also known as a “lav”, “lapel”, or “clip-on mic,” this is a hand’s-free microphone

“WIRED” – a great way to save money: use “wired” microphones unless you NEED wireless

“WIRELESS” – the standard for presenters, comes as a “handheld”, “lavaliere”, or “headset”
