Zoom and Focus
Zoom moves the 10” microfresnel lens in and out to make the image larger. Focus sharpens the
output by moving the air spaced achromatic lens located inside the lamp housing.
MSpeed (Motor Speed)
The MSpeed sets the time required for a motor to complete movement when changing from one
position to another. MSpeed provides a means for all motors to reach their target position at the
same time, even though each motor may have different distances to travel. MSpeed movement is
extremely smooth because the fixture controls its own movements and is not dependent on DMX
refresh rates.
MSpeed times vary from 0.15 seconds to 252.7 seconds. However, if you apply MSpeed to a
parameter, be sure that the delay value (length of time allowed for the entire look) is longer than
the MSpeed value to allow the motors to complete their movement before the end of the cue. An
MSpeed value that is longer than the delay value could produce an undesirable result; for
example, no light output during the scene. For a listing of exact MSpeed times, see
Appendix A:
MSpeed Conversion Table on page 51.
MSpeed can be applied to the Pan and Tilt, Color, and Gobo functions. You can disable Pan and Tilt
MSpeed with the Control parameter to allow MSpeed to apply only to Color and/or Gobo
parameters.
Macros
The Macro parameter controls Internal Effects™ macros. These are factory-programmed
sequences that allow you to quickly program complicated looks in one scene (cue). Each Internal
Effect™ macro modifies a specific set of parameters, while allowing user control of all other
parameters in the scene. The amplitude of the position macro movement is determined by the
Pan Coarse channel and Tilt Coarse channel, respectively. The MSpeed channel controls the speed
of the macros.
With the MSpeed set at the default value of DMX 0-4, an Internal Effects macro completes its
movement in approximately 2.5 seconds. This provides a pleasing look when the additional
variation given by using the MSpeed channel is not required. With the MSpeed set between DMX
5-255, Internal Effects macros complete movement at the selected MSpeed time (up to 25
seconds).
