Shutter Color
The additive RGB color mixing on the shutter fixture may be used to apply a color other than black to the shutter
blades.
Shutter Edge
The edges of all four shutters can be simultaneously adjusted from a hard edge to a soft edge. The softened edge is
centered on the line of the original hard-edged shutter.
Shutter Scale
Adjustment of the scale makes it possible to create an arrangement of the shutter blades and then reduce the size of
the shutter arrangement. Essentially all four shutter blades are being moved equally towards the center of the screen,
while maintaining their relationship to each other.
Shutter Position
Shutter position allows all four shutters to be moved left/right or up/down as a unit.
Shutter Rotation
Shutter rotation rotates all four shutter blades - each one around its own rotation point - by the same amount. This is
not the same as rotating the entire shutter arrangement as a single unit.
Shutter Damping
The shutters in Mbox Designer can have damping applied to them, to smooth their motion. Refer to the Master fixture
"Shutter Damping" on page 18 for more details.

Keystone Fixture
The Mbox software includes keystone correction functionality that is controllable via either an incoming control signal
(Art-Net or sACN) or directly from the Mbox Remote application. The descriptions below refer specifically to
parameters that can be adjusted using Art-Net/sACN. For keystone/warp setup using Mbox Remote, refer to the
separate Mbox Remote User manual.
Keystone correction may be used to remove the image distortion created when you project upon a surface that is not
perpendicular to the axis of projection. The controls act upon a virtual "Keystone Rendering Surface" and allow the
output image to be manipulated so as to correct the squareness of the image, its rotation, size, and linearity.
The Keystone fixture also provides controls for the Tiling function of the server. Tiling provides a quick and simple way
to output a pre-selected portion of the full image without having to use overall scale and positioning controls.
Note: Mbox Designer’s Panoramic Dual and Dual Independent modes both have two (2) Keystone fixtures.
Note: The Art-Net/sACN controllable keystoning does not include warp functionality.
