Glossary
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 Select Programmed beam attributes which can be applied to selected channels using the Beam select
display 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 indi-
vidually.
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).
Saturation is the subjective appreciation of purity, a relation of the intensity of the dominant
wavelength to all other wavelengths (defined by terms such as deep, pale, light, dark).
