Basic Service

Main fuse

The main fuse holder is built in to the mains input socket. Never replace the fuse with one of a different rating!

Unplug the mains cable from the input socket. Pry open the fuse holder and remove the fuse.

Replace the fuse with one of the same type. The fuse rating is listed on serial number label.

Close the fuse holder and replace the mains cable.

Changing the XLR pin-out

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.

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.

Position the jumpers on PL 233 and PL 234 for

the desired XLR pin-out as shown.

Replace the cover before applying power.

Optimizing reflector alignment

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.

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.

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.

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.

Updating software

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.

Normal upload

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.

Boot mode upload

If the data is corrupted during transmission, a check-sum error (

CSER

) occurs and after 15 seconds the fixture

switches to boot mode (

UPLd

) and is ready for a boot mode upload as described in the uploader manual.

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

attempted. When powered on, a check-sum error occurs and the fixture goes into boot mode, ready for a second upload

attempt. Select boot mode upload on the uploader.

If there is no functional software in memory, the fixture must be set to boot mode manually. If the control panel works,

select

UPLd

from the

UTIL

menu and confirm when

SURE

is displayed by pressing [ENTER].
