THE MASKING SHUTTER (chopper) lever is the middle lever projecting through the top of
the optical system housing. The masking shutter blades are operated by this lever to shape the projected spot to
a rectangle, strip spot, or dousing out to full cutoff. The disengaged (full open) position of the masking shutter
lever is to the extreme right (viewed from rear). Varying degrees of masking to complete cutoff are obtained by
moving the lever to the left.
THE ANGLE of the masking shutter blades closure is adjustable and can be set to compensate
for an offset horizontal projection angle, for example, if the spotlight is positioned to the left or right of center
stage. An unbalanced condition will exist while adjusting the blades; lock down the spotlight tilt clamp before
preceding.
REMOVE THE COLOR BOOMERANG and lens mechanism housing as instructed on the
preceding page. Loosen the slotted head screws holding each of the masking shutter blades enough to allow
adjustments. Ignite the bulb and project a spot. Adjust the angle of the bottom blade by tapping it with a
screwdriver so its projected edge lies parallel to the footlights. Tighten the screw. Operate the masking shutter
lever to close the blades. Adjust the upper blade to close against the bottom blade, and tighten the screw.
THE FADE-OUT MECHANISM AND DOUSER CONTROL is the rear lever projecting
through the top of the optical system cover. This lever controls the intensity of light from complete fade-out
(douse) when the lever is to the left, to full intensity when the lever is to the right.
ROTATING THE LARGE KNURLED KNOBS located on the sides of the optical system
immediately behind the boomerang adjusts the fine focus of the lenses and sharpens the edge of the spot. It may
be necessary to re-focus the edge of the spot after zooming from flood to small spot, and from spot to flood.
OPERATION OF COLOR BOOMERANG
THE COLOR BOOMERANG is equipped with six two-part filter holders (51928 gel frame
with slide channel and 51376 cover plate). Six sheets of assorted color gels are included in the spotlight
accessory kit. Additional colors and filter holders can be supplied by your Strong International Dealer. Specify
ROSCOLUX
®
or equivalent high temperature gels.
TO OPERATE INDIVIDUAL COLOR FILTERS, lower the desired filter selector lever. A
rocker catch located in the color disc housing holds the filter in position. To release a color, push the filter
release arm in or engage another color, thus releasing the previous color automatically.
TO REPLACE FILTER HOLDERS, open the front cover of the color disc housing by remov-
ing the thumb screw on the top of the housing. The upper portion of the housing is hinged to allow access to the
color holders. Slide the filter holders up and off the color arms. Replace gel frames as required and secure the
front cover of the disc housing cover when finished.
NOTE: WHEN PLACING COLOR FILTERS in the boomerang, the less dense colors (pink,
amber) should be placed in the holders toward the rear of the boomerang (toward the arc), and those of greater
density (red, green) should be placed in the holders toward the front of the boomerang (away from the arc).
Remember to reverse the gel sequence if reversing the boomerang for left/right operation.
COLOR TEMPERATURE CORRECTION FILTERS, required for use with television and
videotape, can be installed in place of one or more colors. They are available from theatrical supply dealers.
