XT-1 User Manual 43

Note: Optical encoders for pan and tilt instantly correct the fixture’s position if the

fixture is jarred from its programmed position. If a physical obstruction prevents

the fixture from correcting its position, the fixture “times out” to prevent wear on

the motors. If the fixture has timed out, remove the obstruction and home the

fixture to return it to normal operation.

Color Parameters

CMY color mixing is achieved using three color wheels (Cyan, Magenta, and Yellow). A CTO wheel

lets you adjust color temperature. A fixed color wheel provides an additional five factory selected

dichroic color wedge filters.

Color Mix Function

This parameter determines how the cyan, magenta, and yellow color wheels move. The Color

Function values can be enabled in either full speed (controller crossfading the wheel positions), or

MSpeed (MSpeed control of the wheel motor). For more information on MSpeed, see

MSpeed

(Motor Speed) on page 55.

Function

Description

Pure Mix

Allows color wheel movement from open (white) to saturated color (permits a smaller

“step” between color wheel positions for color crossfades). You can select this

function with or without a Quick Path option. When the Quick Path option is selected,

the wheel will pass through the open aperture. When you select the No Quick Path

option, the wheel with rotate through the open aperture.

Continuous

Allows exact positioning of the color wheel from white to full color to white over the full

revolution of the wheel. Using this feature allows you to split the light beam into two

distinct colors. You can select this function with or without a Quick Path option. When

the Quick Path option is selected, the wheel will pass through the open aperture.

When you select the No Quick Path option, the wheel with rotate through the open

aperture.

Spin

Puts all three (cyan, magenta, and yellow) color wheels in spin mode. Wheel Spin

speed, direction, or fixed position can be set individually on CMY channels.

Cycle

Uses only the color-mixing portion of the cyan, magenta, and yellow color wheels to

cycle colors from red to green to blue at variable speeds (rate set by cyan DMX

channel).

Random

Performs a pseudo-random color chase of 12 factory-selected colors using the cyan,

magenta, and yellow color wheels at variable speeds (rate set by cyan DMX channel).

Blink Closes then reopens the shutter between indexed color changes.
