Effects
This section gives details of the effects that can be controlled via DMX. See the DMX protocol table on page
20 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
signal. In other words, the fine channel works within the position set by the coarse channel.
Shutter and strobe effects
The MAC Viper AirFX’s dimmer/shutter provides instant blackout and snap open as well as regular or
random strobe and pulse 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 AirFX’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:
Slot 1 - Blue 101 SP
Slot 7 - Red 310 SP
Slot 2 - Green 203 SP
Slot 9 - Open
Slot 3 - Orange 311 SP
Slot 4 - Half Minus Green SP
Slot 5 - Magenta 522 SP
Slot 6 - Deep Blue SP (Congo)
