Personality
The Atomic 3000 LED provides several options that let you optimize the fixture for different applications in
the
PERSONALITY menu:
• DIMMER CURVE provides four dimming options that apply to both the Beam and the Aura light output
(see Figure 9):
- LINEAR – (optically linear) the increase in light intensity appears to be linear as DMX value is
increased.
- S-CURVE – light intensity control is finer at low levels and high levels and coarser at medium levels.
This curve emulates the RMS voltage dimming characteristics of an incandescent lamp such as the
tungsten halogen lamp of the Martin™ MAC TW1™.
- SQUARE LAW – light intensity control is finer at low levels and coarser at high levels.
- INV SQUARE LAW – light intensity control is coarser at low levels and finer at high levels.
• STROBE BEHAVIOR offers two options:
- LED gives constant light intensity during a flash or a continuous blinder effect. This gives more intense
output and provides an option for reducing flicker on video during a flash or blinder. Note that the
constant intensity obtained at the LED setting will only eliminate video flicker that results from intensity
variations within the duration of the light output. It will not affect video flicker that results from
interruptions in the light output. In other words, flicker may still be visible on video if you set strobe
flashes to a rate that produces interference between the flash rate and the video frame rate.
- XENON replicates the xenon lamp behavior of the original Martin Atomic 3000 DMX by applying a 50
Hz pulse to all light output. No matter how long a flash lasts, it will have this 50 Hz light output pulse.
• VIDEO TRACKING optimizes performance if the Atomic 3000 LED is used with a video source.
In normal use, the fixture processes the DMX signal it receives, tracking (or smoothing out) changes in
values in order to ensure smooth fading between colors and/or intensities. This signal processing takes
fractions of a second and is normally invisible, but if the fixture is used as a pixel in a video display (using
Martin P3™ video system components to convert video to DMX, for example) the processing can interfere
with video response times. If you enable video tracking, the fixture does not ‘smooth out’ DMX input but
instead snaps instantly when a DMX value changes.
For best results, we recommend that you enable video tracking during video display and disable it (the
default setting) during normal DMX control.
• DMX RESET defines whether the fixture or individual effects can be reset by sending a DMX command
on the fixture settings channel. Setting it to OFF can help you avoid accidentally sending a Reset
command during a show, for example.
• COOLING MODE lets you select between five cooling fan options depending on whether your priority is
highest light output or quietest cooling fan operation:
- REGULATE FANS optimizes cooling fan operation for light output. It controls fixture temperature by
varying cooling fan speed up to maximum level and will only limit light intensity if maximum cooling fan
speed is not enough to keep the fixture within its operating temperature limits.
- CONSTANT FAN ULOW / LOW / MEDIUM / HIGH sets the cooling fans to run at constant ultra-low,
low, medium or high speed. If necessary, output intensity is reduced so that the fixture stays within its
thermal limits at the cooling fan speed that is set.
If light output is reduced, the fixture may be reaching its operating temperature limits. To avoid this,
consider the following solutions:
