The signal polarity of the XLR connectors can be reversed,
allowing the fixture to be connected directly to those Martin
devices with reversed polarity (pin 3 -). Optionally, a phase-
reversing cable may be used.
1. Disconnect the fixture from AC power. Remove the 2
Philips screws from the cover on the arm opposite
the side with the visible motor and pull off the cover.
2. Position the jumpers on PL 233 and PL 234 for
the desired XLR pin-out as shown.
3. Replace the cover before applying power.

The MAC 300 reflector is aligned at the factory. Due to differences between lamps, however, fine adjustment may
improve performance.
Strike the lamp and shine the light on a flat surface.
1.
2. See Figure 1. Center the hot-spot (the brightest part of the beam) by turning the 3 adjustment
screws one at a time with a 3 mm Allen wrench. If there is no hot-spot, adjust the reflector until
the light is even.
3. To reduce a hot-spot, "push" the reflector out by turning all 3 screws counterclockwise 1/4-turn at
a time until the light is evenly distributed.
4. If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is
too far back in the reflector. "Pull" the reflector in by turning the screws clockwise 1/4-turn at a
time until the light is bright and evenly distributed.

The latest CPU control software for the MAC 300 is available from your Martin dealer and the Martin web site. This
software is uploaded to the MAC 300 using the Martin MPBB1 Uploader. The display module and feedback system
software are not updated this way.
N o r m a l u p l o a d
Update software is uploaded using a Martin uploader such as the MPBB1. The uploader is connected to the fixture just
like a controller. Under normal conditions, software can be installed from a remote location - there is no need to set the
MAC 300 to boot mode. Please refer to the uploader manual for further instructions.

If a software upload is interrupted, the fixture must be turned off for at least 10 seconds before a new upload can be

attempt. Select boot mode upload on the uploader.
