Beam Effect (Rotating Prism); Iris; Frost; Beam Smoothing - Martin MAC Viper Profile User Manual

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.

Frost

The extent to which the frost filter is added to the beam is variable 0 - 100%.

Beam smoothing

The beam smoothing option available via DMX on the fixture control channel inserts a mild diffuser filter into
the beam to remove any unevenness from the color mixing flags.

Focus and zoom

The focus system allows sharp or soft projections. Focus range varies with zoom angle. At the narrowest
zoom angle, nearest focus is approximately 6 meters (20 feet). As the zoom angle is widened, the nearest
focus distance is reduced, down to approximately 2 meters (6.8 ft.), and far focus can be set to
approximately infinity.
The separate zoom lens varies the focused beam angle from 10° to 44° 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 (figures are approximate):
• 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 control panel PERSONALITY menu. 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 basic 16-bit and extended 16-bit modes.
