The rotating gobos in the MAC 2000 Performance are magnetically indexed with a special indexing gobo holder in position 2. (Position 2 houses the Soft Breakup gobo; see the gobo wheel illustration in the user manual.) The indexing gobo holder, which has a small magnet, must always be in position 2! If it is placed in a different position, the gobos will not index correctly.

The indexing gobo holder accepts the same gobos as normal holders; any gobo suitable for the the MAC 2000 may be placed in position 2.
