Single Gobo Rotator

The Gobo Rotator is designed to fit most ellipsoidal fixtures with a drop in iris slot, and allows a gobo to be rotated in the center axis of the beam. The rotator accepts a stainless steel B size gobo. It is secured in the optical path with a high temperature spring clip and an aluminum retaining ring.

The Gobo Rotator has one variable speed 12V DC motor that controls the speed and direction of the gobo. The motor requires 2 channels of drive for operation, one for forward and one for reverse. The optional DC/DMX controller will operate 2 Double Gobo Rotators or 4 Single Gobo Rotators.

GAM Twin Spin Gobo Rotator

The GAM TwinSpin features ultra quiet operation. It is designed to rotate two patterns in opposite directions in the gate of an ellipsoidal spotlight, creating fantastic kinetic images. The variable speed motor drive can be controlled by almost any dimmer. TwinSpin II may be programmed from your light board and operated as part of a light cue.

ROTATE ONE PATTERN

When you use a single pattern in TwinSpin, ‘what you see is what you get’. The design you choose looks the same as it would if you placed it in a standard pattern holder – but motion is added. Rotating fast or slow, the single pattern can make a simple eloquent visual statement. It is effective as a downlight as well as projected on a cyc, scenery or on people. TwinSpin can also be used as a tool to adjust the position of a pattern by remote control.

TWO THE SAME

When you project two patterns of the same design, TwinSpin rotates them in opposition to each other. The look you achieve is different from the original look of the pattern. It often has a shimmering or sparkling quality. High speed dazzles. Slow movement creates a mesmerizing, dream-like effect. Changing lens focus can change the appearance dramatically. Add gel in your color frame for more variety.

MIXED DOUBLES

Two different pattern designs used in the TwinSpin create a new design-a-hybrid with its own unique visual expression. As the patterns turn, shapes change. Areas of light projection may appear and disappear. It is important to choose two compatible designs so that one doesn’t block out too much light and cancel out the other. With mixed doubles, lens focus can emphasize one or the other or center on both.

ADD A ‘STILL’

You can place one or two patterns in the TwinSpin, then add an additional design in the pattern holder of your fixture. The rotating pattern or patterns will animate the ‘still’. With some experimenting, you can make leaves rustle, flames dance, stars twinkle.

SPINS OFF

Hundreds of patterns are available in ‘B’ size and are suitable for use in the TwinSpin.

Rosco Animation Effects System

The Animation Effects System consists of a gobo (steel or glass) in the pattern slot of any spotlight and an Animation Motor Unit positioned in the color slot with an Animation Disc attached. The Animation Discs are stainless steel discs that are 16.5″ (42 cm) in diameter and are available in eleven different etched pattern designs. The discs, being out of the focal plane, allows sharp focus on the gobo in the pattern slot while the rotating disc animates the effect of the gobo. The effect of rotating these discs creates moving effects such as fire, water or leaves. The key to the system is to choose the right gobo for the base effect.

For instance if you wanted to create reflected water on the underside of a boat you might pick the steel gobo #6363 Reflected Water. Then you choose an Animation Disc that will accentuate the gobo and the desired movement. Animation Disc #30011 Tangential Breakup would be a good choice for choppy, non-specific motion.
