Glossary
Active Attribute: An important difference between cues for Moving Lights and conventional
instruments is that it is necessary to enable only some of the attributes in a specific cue. This
means that a cue can consist of only certain attributes, with all other attributes left in a “no
change” condition. Attributes that are to be updated in a cue are referred to as “Active” attributes
in that cue.
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-3000 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.
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.
