Effects; Dimming And Strobe; Color Mixing; Color Temperature Correction - Martin MAC 2000 Profile User Manual

E
FFECTS
The MAC 2000 Profile is compatible with USITT DMX512 controllers. The fixture has two DMX operating modes,
8-bit and 16-bit.16-bit mode requires four more DMX channels than 8-bit mode but provides more precise gobo
indexing and pan/tilt positioning. All other functions are identical. The complete DMX protocol begins on page 26.

Dimming and strobe

The mechanical dimmer/shutter system provides smooth, high-resolution 100 percent dimming, instant open and
blackout, random and variable strobe effects up to 10 Hz, and random and variable pulses in which the dimmer snaps
open and slowly dims or snaps closed and slowly opens.

Color mixing

The color mixing system uses continuous dichroic cyan, magenta, and yellow (CMY) color filters. It is a subtractive
system that removes color from white light. Inserting all three filters results in loss of light: for maximum brightness,
mix 2 colors at a time.

Color temperature correction

The color temperature correction (CTC) system uses a continuous 0 - 178 mireds color filter that lowers the color
temperature from 6000 K to 2900 K.

Random color mixing

Variable speed random color mixing using the CMY filters may be selected at the top of channel 7. When selected,
channels 3 - 5 set the maximum or minimum amount of each color in the mix. Values up to 127 set a minimum
amount: the color is randomly inserted from the selected value up to 100%. Values over 127 set a maximum amount:
the color is inserted from 0% up to the selected value. To use the full range of a color in the random mix, select a
minimum value of 0% or a maximum value of 100%. To exclude a color from the random mix, select a maximum
value of 0%.

Fixed colors and gobos

The color/gobo wheel provides seven slots with four dichroic color filters and three glass gobos. To change the color or
gobo, see Replacing color filters or gobos on page 20.
The wheel can be scrolled, allowing for split color effects, snapped to fixed positions, and continuously rotated in both
directions at different speeds. When the effects speed channel is set from 252 to 255, the dimmer automatically closes
while the color wheel is moving between static positions.

Gobos

Two overlapping gobo wheels provide room for 10 glass gobos. See page 19 to change gobos.
Gobos may be rotated and shaken at varying speeds and indexed to any position. Extremely accurate positioning is
available in 16-bit mode.
For each wheel, the gobo and type of rotation (indexed or continuous, with or without shake) are selected on the
wheel's Gobo & Function Channel, which also provide commands for continuous wheel rotation. The gobo position
index and rotation speed are selected on its Position/Velocity Channel. In 16-bit mode, the position is further adjusted
on the wheel's Fine Position Channel.
