    N D EX I N G M E T H O D S Effects indexing in the MAC 500 is determined by one of three methods. The adjustment procedure for the effect depends on its indexing method. The lamp must be properly adjusted before the alignment of the other effects can be adequately judged. Refer to procedure 3.11.

    Center the effect in the light path. Begin by visually centering the effect with the lamp off. Then strike the lamp and focus the beam on a flat surface to confirm proper alignment. Adjust if necessary and then tighten both set screws.

    Replace the lamp-socket assembly. Switch on the MAC 500 and wait until the reset has finished. Using either a controller or the control panel, turn on the lamp and focus the light on a flat surface. Center the hot-spot (the brightest part of the image) by using the three adjustment screws. Turn one screw at a time to drag the hot-spot diagonally across the projected image.

    Martin about. The problem is fixed in software from version 1.6. • Missing or incorrectly set jumper: The MAC 500 has a jumper on the PCB to configure the pin-out of the XLR jacks. The default configuration is DMX pin-out, i.e., pin-2 (-) and pin-3 (+). The fixture will not respond to DMX if the jumper is miss- ing or set to Martin protocol.

    the lamp circuit on, measure the voltage across the heavy blue and black wires at the connection block. The reading should be the same as the AC line voltage when the lamp is off. If there is no voltage, but the relay “clicks,” the relay contacts are defective.

    • A bug in versions 1.3 and before causes the DMX signal on a random channel to be misinterpreted for a fraction of a second, after which normal control returns. This is only seen with certain controllers, for example the Strand 520, and can affect any MAC 500 1998-08-03...

    The new belt has part number 372301. Balance plates The achromatic lenses now being used in the MAC 500 are heavier than the first lenses used. To counterbalance the additional weight, two 3 mm thick steel plates are being fastened to the top and bottom of the lamp housing, just in front of the quarter-turn fasteners.
  • Page 27 Changes New head shell The plastic in the shell of the MAC 500 head was changed to another type that withstands higher tem- peratures and has better heat conduction properties. The new shell may be identified by the embossed Martin logo and by the number of ventilation slots over the lamp housing: the old shell has four slots (9 mm wide) and the new shell has 6 slots (3 mm wide).
