Scroller Cartridges and Beam Containment Devices
The Source Four Revolution fixture is provided with a removable scroller cartridge. You can
swap whole cartridges, or you can replace only the gel string within the cartridge. The
scroller cartridge also contains an accessory slot that may be used for a single standard
7.5” color frame or a beam containment device such as a top hat, half-hat or egg-crate. An
attachment point is provided on the underside of the fixture head for safety tethers on
installed beam containment devices.
When using saturated colors for an extended period of time, maximize the scroller fan
speed to extend the life of these gel segments.
C A U T I O N : To ensure optimum pan/tilt movement, beam containment devices must not
exceed .45kg (1 pound) of weight at a center of mass 76 mm (3") from the front of
the fixture. Most standard tophats, half-hats and egg-crates should fall into this
acceptable category. Barndoors and other heavy accessories or devices should be
avoided.
Removing and replacing the scroller cartridge:
Step 1: Loosen the scroller retainer knobs on both sides of the scroller. These knobs do
not need to be completely removed.
Step 2: Pull the latch on top of the scroller cartridge forward and then lift the scroller
straight up out of the head. The gel string is held in tension and may roll back
after being released from the head.
Step 3: To insert a scroller cartridge, lower it straight down into the head so that the top
of the scroller hooks into the head’s lip.
