For details refer to section Introduction.
The Matte 1 (Matte 2) button delegates the digipots to adjust the desired colors.
There are seven preadjusted matte colors selectable.
The Hue control serves to adjust the color. The Chroma control serves to adjust
the color saturation (chrominance). The Luminance control serves to adjust the
desired brightness of the color.
Note: Please note that certain combinations of chrominance and luminance
values will cause overlevels and inadmissible colors. For this reason,
an automatic can be switched on to control limits the chrominance for
defined luminance values.
You can easily check this by setting the Chroma control to maximum
and then turning the Luminance control slowly to maximum; the chro-
minance will be reduced with increasing luminance values.
If the automatic control is switched off an illegal sign indicates a
wrong adjustment.
The Wash button delegates the digipots to adjust the wash parameters Angle,
Pos, Soft. selecting Reset set the parameters to
Angle = Vert
Pos = Mid
Soft = Min.
