D i m m e r / s h u t t e r
The mechanical dimmer/shutter system provides full, high-resolution dimming, and random or variable strobe effects
up to 14 Hz.
The Dimmer Mode ( PER S / dMO d ) setting allows you to select between linear or simulated tungsten fade curves.
For simulated tungsten dimming, the fade time must be set to 0.
C M Y s u b t r a c t i v e c o l o r m i x i n g
The CMY color mixing system is based on graduated cyan, magenta, and yellow color filters. A continuous range of
colors may be achieved by varying the amount of each filter from 0 to 100%. Random CMY color mixing at three
speeds can be selected on DMX channel 6.
The Shortcuts setting ( PE RS/ SCU T ) determines whether or not the CMY wheels always take the shortest path to
the next position; this setting may be overridden on the speed channel in vector mode.
C o l o r
The color wheel provides a 5500 to 2900K color temperature correction (CTC) filter, a UV filter, and 4 saturated dich-
roic color filters. The filters are replaceable; please see "Changing color filters" on page 18, and additional colors are
available from Martin; please see "Accessories" on page 26.
The wheel can be scrolled continuously - allowing for split color effects - or in steps, and rotated continuously in both
directions at different speeds.
The Shortcuts setting ( PE RS/S CUT ) determines whether or not the wheel always takes the shortest path to the
next position; this setting may be overridden on the speed channel in vector mode. Setting the effects speed to "black-
out" causes the shutter to black out the light while the wheel is moving.
F r o s t
The variable frost filter softens and widens the beam. The beam field angle is 18° with no frost applied and increases to
35° with the frost applied fully.
P a n a n d t i l t
The yoke pans 540° and the head tilts 265°. Movement may be optimized for speed by setting the pan/tilt speed setting
( PER S / PTSP ) to FAS T , or for smoothness by setting it to SLOW . This setting may be overridden on the speed
channel in vector mode. Setting the speed to "blackout" causes the shutter to close while the head is moving.
The pan and tilt channels can be inverted and/or swapped in DMX mode with the pan/tilt personality settings ( PE RS
/ P ATI ).
