Effects
This section gives details of the effects that can be controlled via DMX. See the DMX protocol table on page
21 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 Viper Performance’s dimmer/shutter provides instant blackout and snap open as well as regular or
random strobe effects with variable speed from approx. 2 Hz to 10 Hz.
Dimming
The dimmer/shutter provides smooth, high-resolution 100 percent fading.
Fine dimming control is available in extended 16-bit mode.
Cyan, Magenta, Yellow and CTO
The amount of cyan, magenta, yellow and CTO (Color Temperature Control Orange) applied to the MAC
Viper Performance’s light output can be varied from zero to 100%.
The CTO flags installed as standard allow color temperature to be made warmer from 0 to +145 mireds,
giving a reduction in color temperature from 6000 K at zero CTO to 3200 K at full CTO.
Color wheel
The color wheel has seven 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 rotating gobo wheel has five rotating gobos that can be selected, indexed (positioned at an angle),
rotated continuously, and shaken (bounced). The wheel can also be scrolled continuously or shaken. Gobo
indexing, continuous gobo rotation, gobo shake and continuous wheel scrolling are selected on one
channel. Depending on what is selected on this first channel, the gobo indexed angle or gobo rotation speed
are set on the next channel. If gobo indexing is selected on the first channel, fine control of gobo indexed
angle is available on the third control channel in both basic 16-bit and extended 16-bit modes.
Animation wheel
The gobo animation wheel lets you create animated effects by combining animation wheel movement with
gobos. A huge number of possible combinations of beam pattern and movement types is available.
When using gobo animation, adjust the fixture’s focus to obtain the most realistic results.
