Glossary
Attribute: Each adjustable feature of the instruments is referred to as an attribute. Iris, Color
Wheel 1, Gobo Wheel 1 and Pan Fine are all examples of attributes. In some cases, an
instrument attribute will be completely controlled by a single DMX channel. In some cases, more
than one channel may be interpreted to determine the status of an attribute—as is the case with
color mixing. Finally, a single control channel may contain information for two different attributes;
this is the case with some Clay-Paky fixtures that combine Iris and Gobo rotation on a single
channel to minimize the control channel requirements.
Beam: The shape of the beam as modified by passing it through a variety of modifiers (shutter,
iris, gobo).
Board Channel: Lowest level of independent control in the board. A single board channel may
be used to control several dimmer channels.
Bump Button: A switch used to quickly bring a board control to 100%. Pressing a Bump button
is an alternative to flinging a fader to full. The LP-X has a Bump button for each board channel,
located below the fader.
Channel: See Board Channel and Dimmer Channel.
Chase: A repeating pattern of scenes typified by moving marquee lights around the outdoor signs
on the theatre itself. The “rate” of a chase refers to the time each scene is active before being
replaced with the next scene.
Color: A property of a Moving Light. In some fixtures, color is determined by a palette of colors
on a wheel. In other fixtures, color is determined by a mixture of colors on (usually) three filters.
Color (Color Property): Color effects in a Moving Light are generally produced by placing a color
media in the path of the beam. Dichroic filters are the media of choice. Usually a disc with several
filters is placed so that rotating the disc will move one of the filters into position. Some fixtures
have the ability to spin the color wheel continuously for an entertaining effect.
Color Mixing (Color Property): Some advanced instruments use the combination of three-color
media to produce a wide range of colors. Usually referred to as CYM or color mixing, three
channels are used to set the relative saturation of the component colors. This also allows fading
from one color to another without the abrupt change that is characteristic of a rotating color
wheel.
Crossfade: The action of changing smoothly from one scene to another. The intent is a smooth
transition from one look to another over a fixed time. The term “dipless” describes a method of
handling intensity that does not disturb the level of lights with identical settings in the current and
upcoming scenes.
Cue: See Look.
