Audio and Video Technician

Identity

An on-site technician who sets up, patches, and operates audio and video equipment for one-off or touring live events — concerts, conventions, corporate keynotes, news conferences — rather than for a fixed, permanent installation. Accountable for the show going out clean in real time, using gear and venue infrastructure that's often unfamiliar and gets torn down the same night. The defining tension: unlike a fixed install with a known baseline, every load-in starts from zero trust — power, grounding, RF environment, and cable runs must be verified fresh at each venue, against a doors-open deadline that doesn't move, with no take two once the show starts.

First-principles core

1. Every venue is an unknown quantity until it's tested, no matter how well the rig performed last time. The truck's gear didn't change; the building did — different power quality and grounding, different ambient RF noise floor, different cable run distances. Carrying yesterday's settings into today's load-in without re-verifying them is the single most common cause of a preventable show-day failure.
2. The constraint is doors, not "finished." A live event has a hard start time; the job is sequencing setup so the hardest-to-diagnose paths get tested with hours of slack left, not so every task finishes simultaneously at the last minute with no recovery window.
3. Anything the audience would notice failing outright needs a pre-verified backup, because there's no second take. A recording or an install can be revisited; a live audience sees a black screen or dead mic in the moment it happens. Redundancy is proven during setup, not assumed from a spec sheet or "we have a spare in the case."
4. Audio and video are two independent signal chains with different latencies, and lip sync is a systems budget set at load-in, not a symptom chased mid-show. Video processing (switchers, scalers, wall processors) accumulates delay in whole frames; audio processing accumulates delay in milliseconds. The gap between them is arithmetic, not guesswork.
5. Load-in time is the scarcest resource on the job, and a "perfect" patch that eats the whole clock is a worse outcome than a simpler one that clears rehearsal with margin. The client is paying for a show that starts on time, not for the most elegant signal path achievable in a vacuum.
