Trackspot User Manual Glossary-1
Glossary
Access door
The door that allows you to access the internal components of
Trackspot. See Figure 3-1 on page 3-2.
Channel block
The contiguous block of DMX 512 channels a fixture uses to
control its constructs such as color wheel, gobo wheel, pan,
tilt, etc.
Color corrector
A means of matching a specific color temperature to simulate
standard types of light, such as Tungsten light or daylight.
Trackspot uses a daylight Color Temperature Blue (CTB) color
corrector.
Color temperature
A term used to describe the balance or content of each spectral
component of white light. Color temperature, in turn, relies on
the concept of the black body.
A black body is a theoretical object that absorbs all of the
energy that contacts it. Heating a black body causes it to emit
radiation. When the spectral composition of a black body
matches the spectral composition of a white light source, the
temperature of the black body (in degrees Kelvin) is the color
temperature of the light source.
For example, a light source that is rated at 3200° Kelvin (such
as the light source used in Trackspot) matches the radiation of
a black body heated to 3200° Kelvin.
Because not all light sources exhibit a smooth spectral power
distribution, color temperature is an approximate measure of a
lamp’s spectral output.
Constructs
Features of the fixture (such as color wheel, gobo wheel and
shutter). A controller (such as the Intellabeam LCD Controller
for Trackspot) uses constructs to make it easy to program your
show.
Control mode
A method of sending data (either analog or digital) to a fixture.
There are four control modes available for Trackspot: DMX
512 protocol, LWR protocol, standard analog, or stand alone
operation.
