Which term describes a group of 512 DMX channels used for lighting control?

• A. Universe
• B. Bridge
• C. Segment
• D. Rack

Answer: (A)

In DMX lighting, a universe is a block of 512 channels that carries a complete DMX data frame. Each channel controls one parameter (like a dimmer, color value, or effect), so a single universe can drive up to 512 different controls. When you need more than 512 channels, you add another universe, typically labeled as Universe 2, Universe 3, and so on, each with its own 512 channels. The other terms aren’t used to describe this grouping: a bridge is a device that converts between protocols (for example, Art-Net to DMX), a segment isn’t a standard DMX grouping, and a rack refers to a physical enclosure for equipment.
