[. . . ] The standard gobo configuration is shown in Figure 8. All gobos are interchangeable with the following limitations: · On wheel 1 (rotating), the gobo retention spring works with gobos up to 3 mm in thickness. Thicker gobos can be glued to the holder with a UV adhesive or Loctite 330 Multibond with Activator. · On wheel 2 (static), the maximum thickness for gobos is 1. 1 mm. 6 1 8 9 1 2 5 2 7 3 4 3 6 5 4 Figure 8: Gobo wheels as seen from front lens Custom gobos Martin can provide many additional gobos for the MAC 550 Profile, which accepts the same size gobos as the MAC 500. For more information, please visit the Martin web site at www. martin. com. Custom glass gobos should be made with the artwork reversed on the coated side. This orientation minimizes reflections but is not critical. While glass gobos are generally the most durable, satisfactory results can be obtained at less expense with aluminum gobos. Custom stainless steel gobos can also be used, however they can warp, losing sharpness, in a matter of hours. The useful life will depend on the gobo pattern and the projection cycle. Consult your gobo supplier for more information. For best results, custom gobos should meet the specifications listed on page 37. 18 MAC 550 Profile Gobo orientation Figure 9 shows the correct orientation for different gobo types. When in doubt, install gobos with the more reflective side towards the lamp.

The back edge of the gobo cannot be seen when looking through the coated side. When an object is held up to the uncoated side there is a space between the object and its reflection.

Position the head upside down and remove the bottom head cover. Turn the gobo wheel to the desired position. Grasp the holder by the teeth and pull the holder lightly towards the front lens to release the holder and remove it from the wheel. With a small screwdriver or similar, unhook the end of the gobo spring furthest from the gobo and pull out the spring. Insert the new gobo in the holder with the "stage" side down, away from the spring. See Figure 9 and Figure 10.
