COLOUR Colour parameter Changes the colour in a moving light fixture or scroller.
DBO Dead Black Out Button used to turn off all intensity channels.
FILE File A user-defined group of memories, chases and stacks.
FIXTURE Lighting fixture General term for moving yoke and moving mirror intelligent
lights.
FREEZE Page Freeze Page freeze holds memories and chases that have their fader
above zero when new pages or files are loaded.
HTP Highest Takes Precedence A lighting channel parameter typically used to describe
intensity (eg. dimmer channels).
LIBRARY Library list A list of fixtures from different manufacturers, each with
their associated channel parameters, in a text file on floppy
disk. Required to enable patching of fixtures.
LTP Last Takes Precedence A lighting channel parameter typically used to describe
colour, beam, or position.
MASK Masking Masking allows only desired parameters to be re-played.

different beam, different position, different fixture, etc.
PATCH Patch channels Assign faders, fixture & scroller to DMX channels.
POSITION Position/focus parameter Changes the lamp’s position (focus) on a moving light
fixture. Pan (horiz.) and Tilt (vert.).
PREHEAT Lamp filament preheat Some lamp filaments may need to be preheated (typically 2-
