31 Source Four LED Profile v1.4.0 User Manual
RGB
Effectively addresses all 7 colors via three channels of control. The RGB profile produces
medium-quality color crossfades. It makes the Source Four LED series fixtures compatible
with conventional RGB console profiles while maintaining enhanced color production from
the fixture. Also see Color Matching, page 32.
Studio
The fixture produces only white-type light, which is adjustable from 2700 to 6500K. The
Studio profile uses 3 DMX channels to control Intensity, white point, and tint, (the
green/magenta balance). Tint is adjustable without affecting the white point. All three
control parameters are adjustable via DMX as well as onboard with instant access via UI
buttons (no menus to scroll).
For more information, see Studio Settings, page 73. Also see Color Matching, page 32.
Strobe
In most profiles, strobe is assigned to channel 5. It adds another channel to any of the DMX
profiles. Under the Advanced Settings menu, the strobe function may be disabled and the
additional channel for strobe will not be used by the fixture. With strobe at either DMX value
0 or 255, the fixture output is constantly on. At DMX 1, the fixture strobes slowly and
increases in speed toward DMX 254.

Note:
The RGB profile is optimized for maximum brightness at all settings. Sometimes
small changes in RGB values may produce unexpected jumps in brightness.
Shifts in brightness may be perceived during color crossfades in cues and presets.
