Diffuser - Martin MAC 700 PROFILE User Manual

To repl ace the gobo animation wheel
Note: The replacement animation wheel can be inserted with the magnet in or out to suit your application. In
fixed applications, install the wheel with the magnet forwards, away from the drive mechanism, for easier
removal. In touring or similar applications where the fixture is frequently moved, install the animation wheel
with the magnet in towards the drive mechanism for a more secure hold.
1. Disconnect the fixture from power and allow it to cool.
2. Remove the gobo module as described on page 24.
3. Stand the module on the work surface with the cooling fans to your left and the color wheel to your right.
4. Bring the animation wheel to the side of the module closest to you by turning the black belt on the right.
5. To avoid bending the animation wheel while removing, break the magnet's initial hold by prying the
wheel off with a screwdriver inserted from the back. Once you have broken the hold, you can safely
grasp the wheel by the edge and remove.
6. Orient the replacement wheel with the magnet in or out to suit your application (see note above this list).
Place the wheel over the drive mechanism and align the hole in the wheel with the drive pin.
7. Reinstall the gobo module. Verify that the guide pins are correctly seated and that the module is
securely locked.
8. Replace the head cover and release the tilt lock before applying power.

Diffuser

The MAC 700 Profile is supplied with a diffuser installed. This has the advantage of eliminating any pattern
in the light beam that might be caused by the dimmer or CMY flags at very low output levels. However, the
diffuser reduces total light output by approximately 10%. If slight patterning at very low output levels is not
important, you may prefer to boost the maximum light output level by removing the diffuser.
To remove the diffuser
1. Disconnect the fixture from power and allow it to cool.
2. Remove the CMY module as described on page 26.
3. The diffuser is held in a bayonet mount on the lens side of the CMY module. Push the diffuser's metal
outer ring down slightly and turn counter-clockwise to release the diffuser from the three mounting
points. Retain the diffuser for possible re-use.
4. Replace the CMY module and then replace the bottom cover. Release the head lock before applying
power.
5. Reinstalling the diffuser is the reverse of the above procedure. Avoid contaminating the glass with
grease from your fingers. If necessary, remove any traces of grease with 99% isopropyl alcohol and
distilled water.
