LP-3000 Users Manual
Group: A group is a convenient functional set of instruments. An instrument can be a member
of multiple groups. The user creates groups to set cues for multiple instruments at one time. A
group can consist of instruments of different personalities and manufacturer types.
Handle: See Fader.
Highest Takes Precedence: A method of playing back several preset scenes at one time. The
level for each channel is determined by finding the highest level for each channel present in all
of the active (piled-on) scenes. Example:
Recorded
Channel Value
Preset Playback
Position
Result
50% 75% 37.5% (75% of 50)
25% 90% 22.5% (90% of 25)
30% 100% 30.0% (30% of 100)
The output value for the channel with these scenes piled on as shown would be 37.5%.
HTP: See Highest Takes Precedence.
Indexed Gobo (Beam Property): An effect that allows the gobo to be precisely oriented or
indexed. This is important when a pattern is projected, such as a corporate logo.
Instrument: See Moving Light and Dimmer.
Intensity: The brightness of the beam, usually controlled by a mechanical dimmer in a moving
light.
Iris (Beam Property): The iris of an moving light is identical to any other iris—a clever multi-leaf
element that produces a variable sized round aperture. As the iris size changes, the intensity of
the remaining beam remains constant.
Label: A name applied to a specific attribute value or a combination of attribute values. This
allows the user to pick attribute values by names—not by numbers.
Last Takes Precedence (LTP): The method of determining output when several cues are
executed simultaneously. In dealing with dimmer cues, the highest channel level takes
precedence (HTP). With Moving Light cues, the last cue executed takes precedence over the
previous cues.
LTP: See Last Takes Precedence.
Mirror (Focus Property): The positioning of the mirror is responsible for the “focus” or position
of the beam. Generally, stepper motors are used to set the mirror position, with an XY axis for
pan and tilt. Some instruments use a single 8-bit value for mirror position; other instruments use
a 16-bit value. This information is significant only for ensuring that the LP-3000 set-up for an
instrument is correct. Because of the limitations in the pan and tilt mechanisms, the area that a
moving mirror can light is restricted. Instruments such as the Vari*lite and Studio color, on the
other hand, are moving head or true moving lights. These instruments are less restricted in their
range of movement but use all of the features of the LP-3000 Moving Light Controller software
as a moving mirror instrument would.
