Intensity control
Intensity controls for built in profiles
Click the Intensity icon on the Fixture tool bar to access the fixture intensity control.
Example MAC500/Roboscan 918 intensity control displaying special functions
An intensity control usually contains a shutter button, a strobe and an intensity drag bar. The shutter
button controls the fixture shutter (light on/off), while the intensity bar controls the actual intensity of
the light output. Note that not all fixtures have separate shutter and intensity controls, and some
fixtures do not have any intensity controls at all (e.g. Roboscan 812 that uses color and gobo wheels
to obtain a blackout). However with fixtures implementing both a shutter and an intensity control, the
shutter must be opened in addition to the intensity setting to enable any light output (hint: the default
DMX output may be modified so the shutter by default is open). The strobe drag bar controls the
strobe frequency.
Note that shutter, intensity and strobe controls are compatible across fixture types.
Intensity control with lamp on/off
Some intensity controls may implement lamp controls to control power to a fixture equipped with a
halogen lamp. Do NOT confuse this with the lamp control that is for discharge lamps only.
The special functions controls seen in the above example may be shown or hidden from the local
preferences menu.

Intensity control
An intensity control may contain a shutter button and drag bars for strobe and intensity drag. The
actual controls depends on the user defined profile. Some profiles may not have intensity functions at
all, while other fixtures may combine controls on the same channel making it impossible to program
effects individually. Use the shutter button to open and close the fixtures shutter (light on / off) - note
that some fixtures may not have separate shutter and emulates shutter with the gobo or color wheel.
Use the strobe drag bar to program the strobe speed from minimum to maximum frequency - some
fixtures may not implement a separate mechanical strobe but use the gobo or color wheel to strobe.
Use the intensity drag bar to program the intensity level for the fixture.
