MAC Ultra Performance Safety and Installation Manual
Goboholder and gobo orientation, Gobo Wheel 1 (Aerial Wheel)
• Gobo Wheel 1 is the wheel that is closest to the LED light source.
• The side of the goboholder with the gobo retaining spring and with the teeth faces towards the LED light
source.
• The shiny side of the gobo faces towards the spring and towards the teeth in the goboholder so that it
faces towards the LED light source.
• The white, non-reflective side of the gobo faces away from the spring and away from the teeth in the
goboholder so that it faces towards the front lens.
Goboholder and gobo orientation, Gobo Wheel 2 (Breakup Wheel)
• Gobo Wheel 2 is the wheel that is closest to the front lens.
• The side of the goboholder with the gobo retaining spring and without the teeth faces towards the LED
light source.
• The shiny side of the gobo faces towards the spring and away from the teeth in the goboholder so that it
faces towards the LED light source.
• The white, non-reflective side of the gobo faces away from the spring and towards the teeth in the
goboholder so that it faces towards the front lens.
Gobo orientation, Wheels 1 and 2
On both gobo wheels in the MAC Ultra Performance:
• Images or text on gobos must appear correctly (i.e. not flipped left to right) when looking at the
goboholder from the side with the spring.
• The textured side of textured glass gobos must always face towards the spring. The flat side of textured
gobos must face downwards so that the gobo sits flat in the goboholder.
Gobo alignment
See Figure 19. Note
the position of the
alignment marks
(arrowed) on
goboholders and
gobos. Install gobos
with the alignment
marks next to each
other.
Gobo replacement
procedure
Avoid getting grease from your fingers or dirt
onto gobos. Hold gobos by their edges only.
Wear clean nitrile cleanroom gloves when
handling gobos.
To replace a gobo in a goboholder:
1. See Figure 20. Place the goboholder on a
clean surface with the recess for the gobo
and gobo spring facing upwards. Note the
position of the bends (arrowed) in the ends of
the gobo retaining spring. Using a plastic
lever to avoid scratching the gobo, lever one
end of the retaining spring out of the groove
in the goboholder and lift the retaining spring
out of the goboholder.
