Beam Effect (Rotating Prism); Iris; Focus And Zoom; Pan And Tilt - Martin MAC III Profile User Manual

When projecting onto a surface or stage, setting the pattern to horizontal with very slow rotation can
simulate windswept clouds, for example, and setting the pattern close to vertical with faster rotation can
simulate flames. Adjust the fixture's focus to obtain the most realistic results.
The animation wheel can also give mid-air and linear projection effects that are different from rotating gobo
effects in that they do not rotate around a center axis.

Beam effect (rotating prism)

The four-facet prism can be applied at indexed angles or rotated with variable direction and speed.

Iris

The iris can be set to a static diameter, or regular and random pulsing effects can be set with variable
speed.

Focus and zoom

The focus lens focuses the beam from approximately 2 meters (6.5 feet) to infinity.
The separate zoom lens varies the focused beam angle from 11.5° to 55° with the standard lens installed.
Zoom/focus linking
Focus can be linked to zoom so that it automatically adjusts to match changes in zoom angle. Focus on
rotating gobos matches zoom closely, while focus on the gobo animation wheel matches zoom best in the
center of the zoom range and slightly less precisely at the two extremes of the zoom range.
Linked zoom/focus works within 3 distance ranges:
• Near (5 - 10 meters)
• Medium (10 - 20 meters)
• Far (20 meters - infinity)
To link zoom and focus, select a distance range using the Fixture Control/Settings DMX channel or FOCUS
TRACKING in the PERSONALITY menu in the control panel. Then adjust focus to obtain the required
degree of sharpness. Linking is now enabled and focus will auto-adjust.

Pan and tilt

Coarse and fine pan and tilt control are available in both 16-bit and 16-bit extended modes.
Maximum and minimum pan and tilt limits can be set using the control panel (see "Personality – tailoring
performance" on page 16) and via DMX.

Followspot mode

The Martin™ MAC III™ Profile fixture software from version 1.3.0 features a followspot mode in which the
fixture ignores any pan, tilt, or pan and tilt commands sent via DMX or the control menu, releasing the head
for use as a followspot.
In followspot mode the pan and/or tilt motors can be engaged or disengaged from the control menu as a
brake to pan, tilt, or both pan and tilt movement, to prevent head movement when the fixture is not
"manned"; in this case DMX or menu-based control over pan and tilt is still disabled (see "Personality –
tailoring performance" on page 16 and "Control panel menus" on page 52).
Followspot handles can be custom-made by the user to suit the user's own preferences and requirements.
