E FFECTS
The MAC 2000 Performance II is compatible with USITT DMX512 controllers. The fixture has two DMX
operating modes, 8-bit and 16-bit. 16-bit mode requires three more DMX channels than 8-bit mode but
provides more precise gobo indexing and pan/tilt positioning. All other functions are identical. The complete
DMX protocol begins on page 39.
Framing shutters
Optimized for use in theater, the MAC 2000 Performance II features a fully automated, micro-adjusting
framing shutter blade system. For accurate illumination of stage props and scenery, this framing system
slices the beam into angled shapes.
The system comprises four shutter blades, arranged in two layers. With this 2-layer system, the MAC 2000
Performance II has been designed to project shapes with crisp, sharp edges.
Each blade can be swiveled +/- 30 degrees, and the entire module rotates 90 degrees. We recommend that
the angle of each blade, and the alignment of the entire module be set to 50% of their DMX value. This will
set the frame positioning upright, and the shutter blades at right angles. Refer to the “DMX protocol” on
page 39 for the specific channels.
Directly attached to the framing system is the iris. You can use either the iris or the framing system, or both
together.
Gobos
The gobo wheel provides room for 5 gobos. See page 30 to change gobos.
Gobos may be rotated and shaken at varying speeds and indexed to any position. Extremely accurate
positioning is available in 16-bit mode.
The gobo and type of rotation (indexed or continuous, with or without shake) are selected on the wheel’s
Gobo & Function Channel, which also provide commands for continuous wheel rotation. The gobo position
index and rotation speed are selected on its Position/Velocity Channel. In 16-bit mode, the position is further
adjusted on the wheel’s Fine Position Channel.
