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.
Plus 7
Plus 7 adds precision color-control channels to the HSI, HSIC, RGB, and Studio profiles.
For example, HSI with Plus 7 enabled becomes a 15-channel profile. Placing channel 7 at
a value over 51% activates the 15-channel profile within the fixture. The desired color and
intensity is achieved by using the HSI or RGB channels as a starting point. Channels 8 to
14 represent the native LED colors of the fixture and allow you to adjust each color up or
down in order to fine-tune the overall color output.
Color Matching
The color output of all Source Four LED Profile fixtures is calibrated at the factory. When
operating in the RGB, HSI, HSIC, or Studio profile, each fixture makes accommodations for
the specific LEDs in its array and produces output that is consistent with other fixtures,
whether or not they utilize LEDs from the same production batch. Operating in the Direct
Control profile or with Plus 7 settings adjustments bypasses this calibration and multiple
fixtures may produce slightly different outputs when controlled as a group.
N o t e : Depending on the initial color mix, some LED colors may begin at full intensity.
Moving the individual control channels for these colors from 128 to 255 will produce
no effective change from the initial color mix. Conversely, some LED colors may
begin at zero intensity, and moving individual control channels from 128 to 0 will
produce no change.
