The fixed-gobo wheel provides 9 metal gobos plus an open posi-
tion. It has 2 operating modes. In "fixed" mode (
gMO d/F IX ), the wheel steps between fixed positions and
shakes at variable speeds. In "scroll" mode (
SCR L ), the wheel scrolls continuously, shakes at 1 speed, and
rotates at variable speed.
Setting the fixed-gobo speed to "blackout" in vector mode causes
the shutter to black out the light while the wheel turns from one
position to another. The Shortcuts (
determines whether the gobo wheel takes the shortest path to the
next position or turns in one direction only. The setting may be
overridden on the speed channel in vector mode.
R o t a t i n g g o b o s
The Pro 918 has 5 rotating gobo positions. Gobos may be rotated
in both directions at varying speeds or indexed to any position.
The function and gobo are selected on channel 5 and the velocity
or index position are selected on channel 6. Setting the rotating-
gobo speed to "blackout" in vector mode causes the shutter to
black out the light while the wheel turns from one position to
another and, if indexing is selected, while the gobo rotates
between positions.
To change the gobos, see "Changing rotating gobos" on page 20.

The 3-facet prism can rotate in both directions at varying speeds.
There are 8 preprogrammed macros that combine the prism with
rotating gobos on channel 10. These can be disabled by switching

"blackout" in vector mode causes the shutter to black out the light
while the prism moves in and out.
An optional frost filter may be installed in place of the rotating prism to provide a variable frost effect. If the frost filter

The mechanical dimmer/shutter system provides smooth, high-resolution 100 percent dimming, "instant" open and
blackout, random and variable strobe effects up to 23 Hz, and random and variable pulses in which the dimmer snaps
open and slowly dims or snaps closed and slowly opens. The pulse and random strobe effects can be disabled by
