OPERATION OF COLOR BOOMERANG
THE COLOR BOOMERANG supplied with the Gladiator IV is selected when first ordering
the spotlight from the factory. The Type 72-00264 boomerang is mounted within the optical system and uses
(6) 50mm dichroic discs as the color media. Type 72-00709 mounts to the front of the lens barrel and uses
conventional high-temperature color gels (i.e. Roscolux
®
) as color media.
EACH BOOMERANG is equipped with six color arms. A “starter” set of six 50mm dichroic
color discs, or six sheets of commonly-used color gel, is included. Additional colors, including color tem-
perature reduction filters, are available from most theatrical supply dealers.
COLOR FILTERS are controlled by the six color levers of the boomerang. To engage an
individual color filter, lower the desired filter selector lever. A rocker catch located in the color disc housing
holds the filter in the light beam. To release a color, lower the filter release lever or engage another color, thus
releasing the previous color automatically.
TO REPLACE A COLOR FILTER in the 72-00264 boomerang (see Parts List, Figure 5A), it
is recommended to dismount the entire assembly from the optical system and place it on a convenient working
surface. Loosen the (2) quarter-turn fasteners and remove the side cover plate. The entire boomerang assembly
can then be easily removed by loosening the single captive screw securing the boomerang bracket to the base
rail, and lifting the bracket off the (2) locating pins. When re-installing the boomerang, align the holes in the
boomerang base plate onto these pins before again securing the captive screw.
TO ATTACH A COLOR GEL to the color frame of the front-mounted 72-00709 boomerang
(see Parts List, Figure 5B), spray the flat surface of the ring (without the channel clip) with an aerosol adhesive.
Center the ring over a precut 13½ by 13½ inch (34 x 34cm) gel, and press the adhesive-coated side onto the
gel. Trim the excess gel material and install the ring into the boomerang. Old gels can be removed from the
color frame by scraping the gel and adhesive from the frame using a single-edge razor blade.
NOTE: WHEN INSTALLING COLOR FILTERS in either boomerang, the less dense colors
(pink, amber) should be placed in the holders toward the
rear
of the boomerang (close to 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). This measure will prolong the useful life of the filters.
