Effects access hatch and changing gobos and filters
WARNING! Hot surfaces. The MAC 350 Entour becomes hot in use. Either dim LEDs to zero and
allow to cool for 20 minutes or wear clean lint-free heat-resistant gloves before opening the access
hatch.
Effects access hatch
The MAC 350 Entour effects hatch (see Figure 9) gives instant access to gobos and color filters.
Pan and tilt are disabled and
EFHA
appears in the fixture display as soon as the hatch is opened.
If the fixture is powered on, flipping the hatch closed and immediately open again advances one position on
first the gobo wheel and then the color wheel, giving access to each gobo and filter in turn.
To close the hatch, apply firm pressure until you feel a definite click. When the hatch stays closed for more
than a second, the gobo and color wheels reset to their start positions.
The hatch can be removed temporarily by unclipping it from its hinge posts, but it is a very tight fit and care
must be taken to avoid damaging the clips or posts. Removal should not normally be necessary.
Note that if the hatch is not fully closed, it will be impossible to use pan and tilt or reset the fixture.
Changing gobos and filters
Wear gloves while handling optical
components and use only genuine
Martin parts.
Keep all optical components totally
clean and free of grease. Clean them
with 99.9% isopropyl alcohol, especially
if you touch them with your fingers.
To gain access to the optical and effects
components in the head for cleaning
and service:
1. Put on clean lint-free heat-resistant
gloves to protect your fingers and
avoid getting oil on optical
components
2. See Figure 9. Flip the effects
access hatch open.

Custom gobos must be designed so that the true image appears on the more reflective side
so that it faces the LEDs when installed.
