Shutter and Lamp Parameters
Shutter/Lamp Function
The Lamp Function parameter) modifies the Shutter parameter and Dim parameter functions to
enhance and expand the range of effects available on the intellaspot
XT-1 fixture including Light
Burst™ effects, lightning strikes and Electronic Dimming™ effects.
The Light Burst™ effect boosts the Lamp above the 850 Watt level for the specified period of time.
Boosting to white ends with the shutter open; boosting to black closes the shutter. Boosting is also
used to created Lightning effects with the Dim channel scaling the overall brightness.
The intellaspot fixture supports Electronic Dimming™ effects as well as mechanical dimming and a
combination of both. Electronic Dimming™ effect works by lowering the lamp power. Electronic
Dimming alone will not go to black.
Shutter
The Shutter parameter determines the way the shutter is opened and closed. In addition to the
normal functions, the Lamp Control modifies the Shutter parameter to create Lamp Burst,
Lightning, and Electronic Dimming effects. The following table describes the interaction between
the Lamp Function, Shutter and Dim Channels
Shutter/Lamp Function
Parameter Setting
Description
Normal Shutter Functions Opens and closes shutter flags in the optical path
Random Random Strobe Strobes beam using the shutter flags at random intervals
Synchronous Random Strobe
Synchronizes random strobing for all intellaspot fixtures using the
same DMX controller
Lamp Functions
Uses lamp Dimming with the Shutter to produce strobing, Light Burst,
lightening strikes and Electronic Dimming effects.
