GLOSSARY
Glossary of Terms
Active
An intensity value greater than zero (1-100%). When a luminaire is
active
, it will store data for all parameters
(including intensity). Also, a selected submaster and its associated cue are considered active.
Ad Hoc Group
A group of channels selected "on-the-fly" which has not already been pre-stored (as a group). Ad Hoc channel
selection is based on information such as "all channels in a specific preset."
Beam
The size, shape, and sharpness of the light image being output by a luminaire. Also, a function of the luminaire related
to the above characteristics. In a wash luminaire, beam defines lamp centering position. In a spot luminaire, beam
defines the iris size.
Beam Palette
Programmed beam attributes which can be applied to selected channels using the Beam Palette or command-line
keypad.
Blackout
When the console’s overall intensity output level is set to zero (0%).
Board Cue
A method for orchestrating the playback of recorded events on submasters. By using a board cue, a number of cues
and effects can be loaded and activated in faders simultaneously or with timing delays on a cue basis.
Broadcast
Digital data signals transmitted from the control console to the luminaires and interface devices. The signal is
received by all luminaires simultaneously and interpreted by each individually.
Bump
A submaster mode in which pressing the submaster’s [Select] button will instantly "bump" full intensity as provided by
the cue and fader position for all channels in the active cue.
Channel
A control reference which collects a device’s associated thumbwheel address(es) (device, lamp power, etc.) and maps
them to a single selectable number. Channels are assigned via the patch setup. (Also referred to as a "Control
Channel.")
Channel Filter
A submaster mode which allows only the channels selected at the point the channel filter button is deployed to be
enabled on that submaster. Taking the submaster out of channel filter mode enables all channels again. The
channels to be filtered must be selected each time the channel filter is engaged for a submaster.
Color
The subjective interpretation by the human eye and nervous system of electro-magnetic radiation in the 380 to 760
nm band (visible light). Also, a function of the luminaire specified by color and saturation data, or by filter position
data.
Hue is the subjective appreciation of the dominant wavelength of a light source; the attribute of color perception by
which different parts of the spectrum are distinguished (red, orange, yellow, green, blue, violet, purple).
