CONVERT AN ETC SOURCE FOUR SPOTLIGHT INTO A SCENIC PROJECTOR OR GOBO CHANGER! The GAM SX4 ® system offers a choice of four Trays that snap into an ETC Source Four. The Loop Tray allows the use of over 30 GAM pattern loops for scenic projection. The Six-Gobo Tray uses any "M" size gobo from the more than 800 patterns available in GAM's catalog. The Disc Tray uses an 8.5 inch Effect Disc. The SX4 ® is fully modular, so that your Source Four can revert to a conventional ellipsoidal quickly and easily when needed. GAM can also supply a 575 watt HMI Source Four, offering three times the light output. Built with the rugged demands of the theme park, retail and architectural markets in mind, the GAM SX4 ® offers amazing dependability and many options with hundreds of off-the-shelf effects as well as custom designs. Six-Gobo-Tray: Remote control any six "M" patterns, glass or metal. It can be fully DMX controlled and also has built-in programs for automatic pattern changes where a light board may not be available - ideal for display applications. Using the built-in programs you can select speed, direction, and lapsed time of pattern changes, and it will automatically sequence when power is turned on. The Six-Gobo-Tray uses the same power supply as the GAM Indexing TwinSpin and is compatible with some popular power supplies.
