Effects

This section gives details of the effects that can be controlled via DMX. See "MAC III Profile DMX protocol"
on page 46 for details of the channels used to control them.
Where fine control is available, the main control channel sets the first 8 bits (the most significant byte or
MSB), and the fine channels set the second 8 bits (the least significant byte or LSB) of the 16-bit control
byte. In other words, the fine channel works within the position set by the coarse channel.

Shutter and strobe effects

The MAC III Profile's mechanical shutter provides regular or random strobe and pulse effects with variable
speed from 2 Hz to 10 Hz approximately.
To ensure total blackout, the mechanical dimmer also deploys if the shutter is closed for more than 5
seconds.

Dimming

The MAC III Profile's mechanical dimmer provides smooth, high-resolution 100 percent fading.
Fine control of the dimmer is available in 16-bit extended mode.
To ensure total blackout, the mechanical shutter also deploys if the dimmer is reduced to 0% for more than 5
seconds.

Cyan, Magenta, Yellow and CTO

The amount of cyan, magenta, yellow and CTO (color temperature control orange) applied to the MAC III
Profile's light output can be varied from zero to 100%.

Color wheel

The color wheel has 7 color filters that can be applied as split colors or in full-color steps. The color wheel
can also be scrolled continuously, applying the color filters in sequence with control of color wheel speed
and direction. Color filters can also be applied at random at fast, medium or slow speed.

Rotating gobos

The two rotating gobo wheels each have five rotating gobos that can be selected, indexed (positioned at an
angle), rotated continuously, and shaken (bounced). The gobo wheels can also be scrolled continuously or
shaken. Indexing, continuous gobo rotation, gobo shake and continuous gobo wheel scrolling are selected
on one channel for each gobo wheel. Depending on what is selected on this first channel for each gobo
wheel, the indexed angle or rotation speed are set on the next channel. If gobo indexing is selected on the
first channel, fine control of gobo index angle is available on the third gobo wheel control channel for each
gobo wheel in both 16-bit and 16-bit extended modes.

Gobo animation

The gobo animation system lets you create animated effects by rotating the animation wheel and masking
the resulting pattern with one (or even two) gobos.
The system uses two channels:
• On the first channel, you set the animation wheel so that its pattern is horizontal, vertical or set at an
indexed angle, with the animation wheel either static or rotating.
• On the second channel, you can either set the indexed angle of the animation wheel pattern (if you have
set the animation wheel to a static position on the first channel), or set the animation wheel direction and
speed (if you have selected rotation on the first channel).
