All mechanical effects are reset to a “home” position when the fixture is powered up. They can also be reset via DMX
if necessary. Accidental resets can be prevented by turning DMX Reset (
S P E C / d R E S
) off.
An on-the-fly position correction system automatically corrects the position of the color wheels, fixed-gobo wheel, and
rotating gobos. This feature can be disabled by turning Effects Feedback (
S P E C / E F F b
) off.
The Studio Mode setting (
S P E C / M O d E
) allows operation to be optimized for speed (
N O R M
) or quietness
(
S T U d
).

With the default setting, the lamp remains off until a “lamp on” command is sent from the controller. Note: A strong
surge of electric current is drawn for an instant when striking a discharge lamp. Striking many lamps at once may cause
a voltage drop large enough to prevent lamps from striking or trip the main circuit breaker. If sending “lamp on” com-
mands to multiple fixtures, program a sequence that strikes lamps one at a time at 5 second intervals.
The Pro 918 automatically strikes the lamp within 90 seconds of being powered on if the Automatic Lamp On
(
S P E C / A L O N
) setting is turned on. A delay determined by the address staggers lamp strikes to prevent excessive
current draw.
Lamp power can be turned off from the controller. Be careful: it is not possible to strike the lamp within 8 minutes of
having switched it off. Accidental lamp off commands can be prevented by turning DMX Lamp Off (
S P E C /
d L O F
) to off.
P a n a n d t i l t
The mirror pans 180° and tilts 72°. Movement may be optimized for speed by setting the pan/tilt speed (
P T S P
) per-
sonality to
F A S T
, or for smoothness by setting it to
S L O W
. The setting may be overridden on the speed channel in
vector mode. Setting the movement speed to “blackout” in vector mode causes the shutter to black out the light while
the mirror is moving.
The pan and tilt channels (DMX) can be inverted and/or swapped using the pan/tilt (
P A T I
) menu.
C o l o r w h e e l s
The Pro 918 has 2 9-position-plus-open color wheels, yielding a
total of 100 possible combinations. In the standard configura-
tion the wheels combine in 67 useful ways that can be called on
1 DMX channel. The filters on color wheel 1 are easily replace-
able, allowing you to configure the color wheel to suit your
taste. See page 21 for details.
Both wheels can be scrolled, allowing for split color effects,
snapped to fixed positions, and continuously rotated in both
directions at different speeds. The 67 colors can be called ran-
domly on DMX channel 4.
The shortcuts (
S P E C / S C U T
) setting determines whether
the wheels take the shortest path to the next position or turn in
one direction only. The setting may be overridden on the speed
channel in vector mode.
Setting the color speed to “blackout” in vector mode causes the shutter to black out the light while the wheels are mov-
ing.

The beam may be focused from 2 meters (6.5 feet) to infinity. Depending on model, the beam angle is 17° or 23.5°.
I r i s
The iris closes from full open down to 10 percent. There are 6 variable/random pulsating iris effects callable on chan-
nel 9. These can be disabled by switching DMX Macros (
S P E C / d M A C
) off.
