● Main to Sub Crossfade – Manually crossfading from Main module color only → Main
and Sub module color (HTP) → Sub module color only.
Color temperature control (CTC)
The impression X5’s three color mixing control modes (RGB, RGBL and x;y) all offer a
separate Color Temperature Correction channel which lets you shift the color
temperature obtained by the Main module and Sub module when all colors are set to
100% (i.e. R255/G255/B255 in RGB mode or R255/G255/B255/L255 in RGBL mode). A
CTC range of 10 000 K to 2500 K is available.
Depending on the selected Color Mix Mode (RGB, RGBL or x;y), if you select a color
temperature on the CTC channel, the fixture will no longer use the specific open color
and will instead use the selected color temperature.
If you select a color temperature on the CTC channel, it is still possible to manipulate
the color temperature using the RGB and RGBL channels.
Note
To obtain the desired color temperature on the CTC channel, all ColorMix channels
need to be set to 100%. If they are not at 100%, the system will mix color relative to the
selected white point of the CTC channel.
The CTC channel affects all the fixture’s modules. Setting the CTC channel to a specific
color temperature will affect the open white of the Main module and Sub modules.
Color Quality Control (CQC)
The CQC channel lets you modify the spectral mix of the white color output in order to
achieve a balance between better color rendering or higher output. Physically, the
richer light spectrum created when deploying multiple LEDs will give better color
rendering but will also give lower output. On the other hand, you can obtain higher
output if you accept lower color rendering.
While using white colored light, the CQC channel lets you change between white with
priority on high-quality color rendering and white with priority on highest output.
Additionally, the CQC channel lets you smoothly desaturate colors. If you have set a
saturated color in the color mix, the CQC channel lets you smoothly desaturate the
color from saturated to fully unsaturated (= white).
The following options are available:
● High Quality (HQ) – Color is mixed with priority given to the best white color
rendering quality. Saturated colors will have maximum saturation at DMX 000 and
will smoothly become unsaturated until they reach 0% saturation (= white) at DMX
value 127.
● High Output (HO) - Color is mixed with priority given to the highest output in white.
Saturated colors will have maximum saturation at DMX 255 and will smoothly
become unsaturated until they reach 0% saturation (= white) at DMX value 128.
