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 and soft qualities of a spot luminaire. While some fixtures may call
this parameter "focus", it is always represented as "edge" in Ion, 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.

Image is the collection of parameters that affect the contents of the beam (gobo, prism, effects
wheel, etc.).
