44 MAC III Performance user manual
Gobo orientation
The orientations shown in Figure 23 are correct in most cases, but consult your Martin dealer or gobo
supplier if you are in any doubt about the orientation of a specific gobo type. To minimize the risk of heat
damage, priority must be given to installing gobos with their more reflective sides facing the lamp.
Coated Glass Gobos
The heavy matted aluminum coated borosilicate gobos in the MAC III Performance are
factory-installed with the more reflective sides facing towards the lamp. Replacement
gobos must also be installed with more reflective sides facing the lamp.
More reflective side towards lamp
To minimize the risk of gobo overheating
and damage, turn the more reflective side of
a coated gobo towards the lamp.
Less reflective side away from lamp
The less reflective side of a coated gobo will
absorb less heat if it faces away from the
lamp.
Textured Glass Gobos
Textured side towards lamp Smooth side away from lamp
Textured glass gobos in the MAC III Performance sit most squarely in the gobo wheel with
the textured side towards the lamp. If in doubt, consult your Martin dealer or gobo supplier.
