CED Audio-Visual & Production Design 2 — Questions and Answers
Question 1: What does IMAG stand for in large-scale event production?
- Integrated Media and Graphics
- Image Magnification (Correct answer)
- Interactive Media and Audience Guidance
- Immediate Audio-Graphics
Correct answer: Image Magnification
IMAG stands for Image Magnification, the live video system that projects close-up camera shots of presenters or performers onto large screens so all audience members can see clearly.
Question 2: In event rigging, what does 'SWL' stand for?
- Standard Wire Load
- Safe Working Load (Correct answer)
- Structural Weight Limit
- Stage Working Length
Correct answer: Safe Working Load
SWL stands for Safe Working Load, the maximum load that rigging equipment is certified to safely support under normal working conditions.
Question 3: In event lighting, what are 'gobos' used for?
- To protect lighting fixtures from rain at outdoor events
- To block and shape light or project patterns and logos onto surfaces (Correct answer)
- To measure the intensity of a lighting fixture's output
- To diffuse harsh direct light into a softer ambient glow
Correct answer: To block and shape light or project patterns and logos onto surfaces
Gobos are metal or glass inserts placed in a lighting fixture's beam path to block portions of light and project patterns, textures, or custom logos onto surfaces.
Question 4: What is the purpose of a stage monitor (floor wedge) in live event production?
- To project sound toward the audience in the rear of the venue
- To allow performers on stage to hear themselves and the audio mix (Correct answer)
- To isolate sound from different zones of the venue
- To record the live performance for post-production
Correct answer: To allow performers on stage to hear themselves and the audio mix
Stage monitors are speakers positioned facing the performers on stage, allowing them to hear themselves and other audio elements without relying on the house speakers directed at the audience.
Question 5: In event audio, what does a 'line array' speaker system refer to?
- A single high-powered speaker at the center of the venue ceiling
- Multiple speakers arranged vertically that work together to direct sound precisely over long distances (Correct answer)
- Audio cables routed along the floor to connect all speakers in sequence
- A mixing console with multiple input channels arranged in a row
Correct answer: Multiple speakers arranged vertically that work together to direct sound precisely over long distances
A line array is a vertically arranged cluster of speaker elements that, through acoustic coupling, projects sound over long distances with controlled vertical dispersion and even coverage throughout the audience.
Question 6: What is the primary function of a video production switcher at a live event?
- To convert video signals from digital to analog format
- To select and transition between multiple video sources for the live program output (Correct answer)
- To simultaneously record video from multiple cameras to storage
- To upscale lower-resolution video signals to HD
Correct answer: To select and transition between multiple video sources for the live program output
A video production switcher allows the operator to select from multiple video sources—cameras, playback, graphics—and execute transitions between them for the live program output.
Question 7: What type of fixture is a 'moving head' in event lighting?
- A stationary LED panel with an internal rotating color wheel
- An automated luminaire that can pan, tilt, change color, and alter beam shape via DMX control (Correct answer)
- A spotlight mounted on a motorized ceiling track system
- A traditional follow spot operated manually by a lighting technician
Correct answer: An automated luminaire that can pan, tilt, change color, and alter beam shape via DMX control
A moving head fixture is an automated luminaire with motorized components that allow remote DMX control of pan, tilt, color, gobo selection, and beam size, enabling dynamic lighting effects without manual repositioning.
