Which modes are calibrated in ETC LED fixtures?


ETC calibrates its color-mixing LED fixtures in the factory. This ensures that each fixture type gives the same color output when it receives the same DMX values, compensating for the natural variation in the LED emitters themselves.

Depending on the fixture, only some of the DMX modes may be calibrated. This list summarizes the different fixtures and their modes.
