MAC 250 Beam Installation Note 4
7. A set of six beam effect gobos (P/N 62420250) is supplied in the Kit. See Figure 6. To install a beam
effect gobo, remove a color filter from the color wheel by pressing it gently away from its retaining
tabs (A) and lifting it carefully out of the color wheel (B).
8. Filters and gobos have small beads of silicone applied to them to act as cushions. If a bead of
silicone from a color filter has become stuck to the color wheel, remove it and replace it on the color
filter.
9. Insert gobos with the silicone beads facing the color wheel with reference to Figure 7 and to the
illustration on the last page of this guide. Store the original color filters safely for possible future
re-use.
10. We recommend that you install beam effect gobos in the
color/gobo wheel in the positions seen from the front lens
side* shown in Figure 7 in all the fixtures you modify, so that
all MAC 250 Beam fixtures will have identical behavior under
DMX control. A larger copy of this illustration is included on
page 6 of this guide.
*The previous revision of this installation note showed the
color/gobo wheel seen from the lamp side. Figure 7 shows
the wheel seen from the front lens side instead to give a true
picture of the wheel in reality, because the front lens side is
where the color filters/gobos are actually installed. Note that
when viewed from the front lens side, the gobo slots are
numbered counterclockwise.
11. See Figure 8. The new
front lens assembly (P/N
62409076) has a safety
cable with a carabiner
clip. Attach the clip to the
head using either of the
two holes (A) provided in
the new front lens
mounting bracket, then
push the clip flat (B) to
give space for the front
lens assembly.
