Effects

This section gives details of the effects that can be controlled via DMX. See the DMX protocol table on page
19 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 Wash'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 Wash'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.

Focus and zoom

The focus system allows a sharp or soft beam edge. Focus range varies with zoom angle. At the narrowest
zoom angle, nearest focus is approximately 6 meters (20 feet). As the zoom angle is widened, the nearest
focus distance is reduced, down to approximately 2 meters (6.8 ft.), and far focus can be set to
approximately infinity.
The separate zoom lens varies the focused beam angle from 10° to 44° with the standard lens installed.
Zoom/focus linking
Focus can be linked to zoom so that it automatically adjusts to match changes in zoom angle.
Linked zoom/focus works within 3 distance ranges (figures are approximate):
• Near (5 - 10 meters)
• Medium (10 - 20 meters)
• Far (20 meters - infinity)
To link zoom and focus, select a distance range using the Fixture control/settings DMX channel or FOCUS
TRACKING in the control panel PERSONALITY menu. Then adjust focus to obtain the required degree of
sharpness. Linking is now enabled and focus will auto-adjust.

Pan and tilt

Coarse and fine pan and tilt control are available in both basic 16-bit and extended 16-bit modes.
