Static Wheel Module (SWM)
The Static Wheel Module contains a wheel with three positions for static M-size steel or
glass gobos or dichroic color filters and an open position. If desired, the open position can
be used to hold a fourth gobo or filter.
C A U T I O N :
To prevent cracking of glass gobos and for best image contrast, the silver reflective
surface of the gobo must face the lamp and the black surface of the gobo must face
the lenses.
Controlling the Static Wheel Module
The Static Wheel Module uses an 8-bit channel to select the frame. Only full frames can be
produced. Use the table below to set the Wheel Position channel.
