AudioVisual Terms made Easy !

 A quick reference guide to terms used in the AV world.


  • Conventional lights:  These are non-moving lights that provide color changes to the stage or backdrop, as well as highlight with specific spotlights. They also can be used to “wash” the stage, providing even lighting coverage across the whole set.


  • Moving Lights:  Lights that can be programmed to move, change color, and design all by selecting cues throughout the presentation.


  • Audio Mixing Console/Soundboard/Mixing Board:  A mixing board enables a technician to control all of the incoming sound sources and send them out of the loud speakers. The size of the mixing board depends on the quantity of sound sources that need to be amplified.


  • Dual Pole Stands:  Stands that enable the technician to mount any size monitor at adjustable heights. Dual pole stands can have a flat base, which is more for an immobile setup, and they can also have bases with wheels that enable movement to any location without having to re-mount the monitor.


  • Truss:  A structure holding various lights as well as audio and/or video components. The moving and non-moving lights can be clamped on the truss in many ways to get nearly any desired effect. Display monitors can be mounted on the truss in many positions vertically or horizontally to face any direction the audience may be viewing from.


  • Fast Fold Screens:  Projector screens that have a large, foldable frame. These screens are typically used in larger rooms, such as banquet rooms or convention centers.


  • Monitors:  LCD and Plasma monitors are displays that can be used with cameras, DVD players, computers, and other video sources.


  • Advancers:  Enables the presenter to wirelessly forward to each next slide, without having to directly interact with the computer. Many advancers include laser pointers, which are helpful if the presenter is not able to be close to the screen.


  • Confidence Monitor:  A monitor that faces away from the audience towards the stage for the presenter to be able to see themselves while presenting. They can also be used to switch between the presenter, presentation script, notes, and the live video feed.


  • Strike/Breakdown:  After the technicians deliver, set up, and operate the equipment for the client’s events, they “strike” the equipment. Striking is an industry term for taking down the set, wrapping cables, and packing up all of the equipment to return it back to the warehouse.


  • HD Projectors compared to standard:  HD projectors, or High Definition projectors, are a higher resolution display than standard projectors. The rows of pixels are scan lines, which make up for the number resolution vertically and horizontally. 720p for example, has 720 lines vertically from top to bottom of the screen. A 16:9 widescreen aspect ratio would make the left to right scan lines add up to 1280. This makes it a resolution that is 1280 x 720.


  • Dress Kit:  The extra framing that adds optional draping on the left, right, top, and bottom of fast-fold projector screens. This is useful for filling in space surrounding the projector screen, and concealing a wider area behind it from the audience’s perspective.


  • Lav:  Also known by their full name, lavaliers. They are small microphones that clip on to the presenter or subject’s clothing in close proximity to their vocal source. Lavaliers are typically connected to a wireless pack, which transmits the audio back to the sound board.
