Form Control
Form (a subcategory of Beam) collects the parameters that affect the quality of the beam, including
the iris, edge, frost, etc. ‘Shutter’ and ‘Image’ are the other two subcategories of Beam
When the form encoder page button is selected, the LED will illuminate and the encoders
automatically populate with the “Form” parameters as specified in the show patch. If there are more
parameters in the show patch than will fit on the first page of the encoders, press the [Form] button
again to page through the remaining parameters in the category or press [Form] and a page
number to jump to a specific page.
The form parameters may include:
• Edge - controls the hard/soft qualities of a spot luminaire. While
some fixtures may call this parameter “focus”, it is always
represented as “edge” in Eos, to avoid confusion with “Focus”
which refers to pan and tilt data. The edge encoder provides two
buttons, [Hard] and [Soft], which set the selected luminaire to its
hardest (sharpest) edge or its softest edge. These values are set
to the system default value for the selected luminaire, but may be
modified as required on a per fixture basis.
• Iris, Zoom, Strobe and IMF- each parameter has in/out, narrow/
wide, or fast/slow settings. Iris and Zoom also have
programmable limits, called in/out and narrow/wide respectively.
The strobe mode setting varies based on the fixture type.
