Zoom / Focus Optimization
The Artiste Rembrandt utilizes a zoom and focus lens to control the beam. For highest efficiency, the
fixture contains an algorithm that automatically adjusts the focus lens to its ideal position in
relationship to the zoom lens.
Note!
The correct lens type (Fresnel or PC) must be selected in the menu, or via the DMX control
channel to ensure that the focus lens is positioned for the highest output.
To use the Zoom optimization, set the focus channel between DMX 0 to 10. This will ensure the fixture
performs at its best with the highest output and optimal field. Taking over focus control, for example
to adjust the sharpness of the animation wheels or internal framing module, simply set the focus
channel within its normal range from DMX 11 to 255. All optimizations are disabled. Do not forget to
set the focus back to the Optimization range when the effect is removed from the beam; otherwise,
the Rembrandt could lose more than 30% of its output. It is advised to create a console preset of the
focus @ DMX 0, a setting that is easily accessible. Not setting the focus to the optimization (e.g. having
a console default of 127 / 50%) will greatly reduce the light output of the fixture and result in poor
performance. Please ensure console profiles are correctly defined with focus default @ 0.
Zoom Overdrive
The Artiste Rembrandt allows the zoom lens to go past its optimal narrow position, thus “overdriving”
it. Although this creates a slightly smaller beam, its efficiency is reduced. As the fixture may lose a bit
of output when moved into the zoom overdrive range, it is mapped to the DMX range of 0 to 20;
however, despite this reduced output, the resulting column of light, especially using the PC lens, is a
useful effect. The overdrive range is provided as a simple way for the operator to know the ideal zoom
range for maximum efficiency.
