how many "channels" are there in a DMX 512 universe?

• A. 512
• B. 256
• C. 1024
• D. 128

Answer: (A)

DMX 512 defines 512 data slots, or channels, in each universe. Each channel carries an 8-bit value (0–255) that sets a parameter on a lighting fixture, such as dimmer, color, or position. Because one universe holds 512 of these channels, you can independently control up to 512 parameters in a single DMX data stream. If you need more control than one universe provides, you add another universe, which brings in another 512 channels with its own addressing. The other numbers don’t fit because they would violate the standard’s defined size for a universe.
