Av work meaning
In workplace discussions of meetings, events, and presentation equipment, AV usually means audiovisual. It covers sound and visual systems, such as microphones, speakers, displays, and projectors. A specific employer may use the abbreviation for a job or team with a narrower scope.
Meaning and context
An AV role can involve setup, testing, operation, and troubleshooting. The exact duties differ between a conference venue, school, office, and production environment. Read the job description rather than assuming that every AV position includes the same technologies.

Examples and usage
An AV check before a meeting might test the microphone, display connection, and playback sound. An AV technician may coordinate equipment for an event. Those examples identify a practical function rather than a particular certification or salary level.
What to check
If AV appears outside an equipment or event context, ask what the organization means. Internal abbreviations can have other expansions. For a support request, describe the problem clearly: no sound, an unreadable display, or a failed connection is more actionable than AV is broken.
