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 38.

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 38 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 29 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.

Gobo animation system

The gobo animation system is designed to create animated effects such as flames, sky and water imaging. The MAC
2000 Performance II comes with 5 replaceable gobo animation wheels, which are magnetically attached to the motor
