14. CHANGING/REPLACING GOBOS/COLORS Before attempting to change any gobos or color be sure to follow the effects module
removal process as described in the previous section (section 13) of this manual.
The POWER SPOT 700 II includes both Aluminum (thickness = 0.3 mm) and Glass
(thickness = 1.1 - 3.0 mm) gobos (outside diameter 26.9 mm, viewable image size 23
mm). There is one rotating Gobos wheel (user replaceable gobos) and one fixed Gobo
wheel (non replaceable gobos).
14.1 General guidelines for exchanging Gobos and Colors
All Gobos and Color filters have a specific optical orientation that must be
observed. To prevent damage to the gobos and color filters and to optimize the
optical image, all effect should be mounted with their reflecting side in the direction
of the lamp. For example;
Aluminum Gobos must be mounted with their unpainted side toward the lamp.
The black painted side should go in the direction of the front lens.
Glass Gobos must be mounted with their reflective side toward the lamp. In the
case of glass gobos the reflective side of the gobo is sometimes hard to
distinguish. An easy way to distinguish the reflective side is to hold a pencil directly
in front of the Gobo. If the pencil is in front of the uncoated side of the gobo you will
see thickness of the Glass Gobo between the mirror image and the pencil. This is
the reflective side that should be mounted towards the lamp. See the illustration on
the next page; notice the pencil image on the left has a mirror reflection further
away from the pencil as the mirror reflection on the right.
