The MAC 575 Krypton features two color wheels, each with 8 interchangeable dichroic color filters and an
open position. As standard the MAC 575 Krypton is supplied with 15 color filters and a CTC (color
temperature control) filter installed. The illustration shows the filter positions as seen from the lamp side.
The DMX Protocol on page 29 gives details of color filter selection.
Replacing a color filter
Note: Wear cotton gloves while handling color filters and use only
genuine Martin filters.
When the fixture resets, the filters at slot 8 in wheel 1 (red) and slot 1
in wheel 2 (green) black out the fixture while the shutter resets. If you
remove or replace these filters, the fixture may blink during a reset.
1. Disconnect the fixture from AC power and allow it to cool.
2. Lock the head in the upside-down position (the indication TOP on
the back of the head must be upside down) and remove the
bottom cover.
3. For best access, align the rotating gobo wheel so that the open
position is above the color filter to be replaced (see arrow in
Figure 9).
4. Turn the color wheel to access the desired filter position. Press
the filter forwards slightly to release it and then grasp it by the
edges and remove. If your fingers are too large, protect the glass with a piece of paper that has been
folded several times and grasp the filter with needle nose pliers.
5. To insert a filter, slide it under the retention spring until it snaps into place.
6. Replace the cover and unlock the head before applying power.
