• The SPEED menu gives you two movement speed options:
- PAN/TILT SPEED lets you set pan and tilt movement to FAST (optimized for speed) or SMOOTH
(optimized for smooth movement – useful for slow movements in long-throw applications).
- EFFECT SPEED lets you set all the fixture’s effects to FOLLOW P/T (effects speed follows the speed
set for pan/tilt), FAST (optimized for speed) or SLOW (optimized for smooth movement – useful for slow,
gradual effects changes).
• DIMMER CURVE provides four dimming options (see Figure 6):
- LINEAR – (optically linear) the increase in light intensity appears to be linear as DMX value is
increased.
- SQUARE LAW – light intensity control is finer at low levels and coarser at high levels.
- INV SQUARE LAW – light intensity control is coarser at low levels and finer at high levels.
- S-CURVE – light intensity control is finer at low levels and high levels and coarser at medium levels.
This curve emulates the RMS voltage dimming characteristics of an incandescent lamp.
• TUNGSTEN EMULATOR gives the warm appearance and warm shift dimming characteristics of a
tungsten lamp fixture.
• FOCUS TRACKING sets focus to automatically adjust to match the fixture’s zoom angle. You can enable
or disable focus tracking, and you can optimize this feature to give the best performance at far, medium or
near projection distances.
• VIDEO TRACKING optimizes performance if the MAC Ultra Performance is used with a video source.
In normal use, the fixture processes the signal it receives, tracking (or smoothing out) changes in values
in order to ensure smooth fading between colors and/or intensities. This signal processing takes fractions
of a second and is normally invisible, but if the fixture is used to display video the processing can interfere
with video response times. If you enable video tracking, the fixture does not ‘smooth out’ input but instead
snaps instantly when a value changes.
For best results, we recommend that you enable video tracking when using video as a source and disable
it (the default setting) during DMX control.
• DMX RESET lets you reduce the risk of accidentally sending a reset command via DMX that might cause
an unwanted blackout and/or unwanted light output in the middle of a show, for example, that will take
several seconds to recover from.
• EFFECT SHORTCUTS determines whether the color and gobo wheels take the shortest path between
two positions (shortcuts enabled), crossing the open position if necessary, or always avoid the open
position (shortcuts disabled).
• COOLING MODE lets you select between five cooling fan options:
- CONSTANT FAN FULL optimizes cooling fan operation for the lowest possible temperature by setting
cooling fans to run constantly at full speed. Light output intensity is reduced if necessary to prevent the
fixture from exceeding its maximum operating temperature during full speed fan operation.
- CONSTANT FAN MEDIUM sets cooling fans to run constantly at medium speed. Light output intensity
is reduced if necessary to prevent the fixture from exceeding its maximum operating temperature during
medium speed fan operation.
- CONSTANT FAN LOW sets cooling fans to run constantly at low speed. Light output intensity is
reduced if necessary to prevent the fixture from exceeding its maximum operating temperature during
low speed fan operation.
- CONSTANT FAN ULOW (ULTRALOW) optimizes cooling fan operation for the lowest possible noise by
setting cooling fans to run constantly at ultra-low speed. Light output intensity is reduced if necessary to
