If you’ve ever sat in a production meeting and felt like the AV team was speaking another language, you’re not alone. From line arrays to confidence monitors, the world of event AV has its own vocabulary. But learning the basics can go a long way toward smoother planning, clearer communication, and stronger outcomes.
Here’s your cheat sheet to speaking “Event AV” like a pro:
🎛 Audio Terms
Mixer (Audio Console) – The brain of the audio system. It controls what’s heard through the speakers and allows adjustments to volume levels, EQ (equalization), and more.
Wireless Lav/Lapel Mic – A small, clip-on microphone often used by speakers or presenters. It’s hands-free and discreet.
Handheld Mic – Exactly what it sounds like — a mic held in the hand, often used for Q&As or performances.
Line Array – A stack of speakers arranged vertically for consistent, powerful sound coverage across a large space.
Feedback – The high-pitched squeal you never want to hear. It occurs when sound from speakers loops back into a microphone.
🎥 Video Terms
Switcher – A device that allows you to switch between multiple video sources (such as a laptop or camera) in real time.
Projection Mapping – The art of using projectors to transform physical spaces (like walls or sets) with immersive video content.
PJ – Another way to say a projector.
Confidence Monitor or DSM (down stage monitor) – A screen placed on or near the stage, facing the presenter, to display slides, speaker notes, or timers—so they don’t have to turn around.
IMAG (Image Magnification) – A live video feed (usually of a speaker) displayed on big screens to help the audience see clearly.
💡 Lighting Terms
Uplighting – Lights placed on the floor that shine upward on walls or columns. Ideal for adding ambiance and color to the space.
Gobo – A stencil or template inserted into a lighting fixture to project a shape, pattern, or logo.
Wash Light – A soft, even light that “washes” a space in color or white light.
Spotlight – Focused lighting used to highlight a presenter or specific area.
🧠 Tech Crew Roles
A1 (Audio Lead) – They manage all things sound.
A2 (Audio Assistant) – Supports the A1, usually handling microphones and backstage cues.
V1 (Video Lead) – Oversees video playback, switchers, and screen feeds.
L1 (Lighting Designer) – Designs and runs the lighting for your event.
PM (Project Manager) – Your go-to for everything. They coordinate the crew, timelines, gear, and run of show.
TD (Technical Director) – Oversses the technical aspects of an event, overseeing the setup, operation, and troubleshooting of all technical equipment, such as sound, lighting, video, and stage design. They ensure the event runs smoothly and meets the production’s requirements.
🧰 Other Useful Lingo
Load-In / Load-Out – The setup and teardown process for AV gear. Time it right — it’s not a quick job.
Cheeseborough – It is a type of pipe clamp that is used to fix equipment or scenic elements to truss or other pipe structures.
Gaff Tape – A heavy-duty, cloth-backed adhesive tape, that is strong yet has easy-to-remove adhesive and is a non-reflective matte finish. It’s known for its versatility in securing cables, labeling equipment, and generally keeping things tidy and safe on events.
Rigging – The process of hanging gear like lights or speakers from trusses or ceilings.
Backline – Musical instruments and gear like drum kits or amps provided for performers.
Run of Show (ROS) – The master schedule detailing every cue, segment, and presenter.
In Review
You don’t need to be fluent in AV to have a great event, that’s what your production partner is for. But having a basic understanding helps you ask the right questions, make informed decisions, and collaborate more effectively.
At AV Chicago and Show Ready Productions, we believe AV should never feel like a mystery. Whether it’s your first event or your fiftieth – we’re here to speak your language and translate the rest.
