An AV installer works with audiovisual systems to install, set up, operate, troubleshoot, and repair equipment, like speakers, recording tools, and cameras. As an AV installer, your duties include setting up the equipment to work within a specific space, testing the equipment before a show or broadcast, and optimizing the quality of audio and visuals for the show or broadcast. Your responsibilities also include transporting equipment between different sets, performing basic maintenance and repairs on AV equipment, and installing some equipment to use permanently. AV installers keep detailed records of all installations, maintenance, and repairs to AV equipment and systems.
