GENERAL INFORMATION

Source Four Fresnel with attached dimmer

ETC combines the efficiency of the HPL lamp with the singular optical qualities of the fresnel optical system to create the truly advanced ETC Source Four Fresnel. Traditional fresnel optics provide a unique quality of blending wash light and beam shaping via barn doors for well-defined, soft-edged area lighting. The Source Four Fresnel combines this classic system with a unique reflector design enabling the HPL 750W-equipped Source Four Fresnel to equal the lumen output of other 1000W fresnel fixtures. Spot-to-flood focus is accomplished by large, easy-to-use knob for quick adjustments in inconvenient positions. The unique Quick eXchange socket design permits re-lamping from underneath the fixture without breaking focus in most situations.

PHYSICAL

• Rugged die-cast aluminum construction
• Convenient full-size zoom adjustment knob
• Unique HPL Quick eXchange socket enables easy lamp changes
• Sliding yoke mount for variable balance point
• Fully enclosed accessory slots for no light leak
• UL and cUL listed

ELECTRICAL

• 100V-240V, 50/60Hz
• High temperature three-conductor 36” leads in a glass fiber outer sleeve
• Supports ETC Dimmer Doubling™ technology

OPTICAL

• 7”/175mm aperture
• Zoom range
• 9°-52° beam angle
• 20°-65° field angle
• True fresnel optical system for good barn door beam shaping performance
• Glass reflector with dichroic coating optimized for HPL performance

LAMP

• HPL – compact tungsten filament contained in a krypton/xenon-filled quartz glass envelope (see table for suitable lamp types)
• Uses same lamp as all Source Four fixtures for common inventory
• 750W maximum
• Patented filament geometry makes for extremely efficient light collection and transmission
• Integral die-cast aluminum heat sink lamp base
• Connectorized Stage-pin power cable input

DIMMER

The Source Four Dimmer offers a new standard in high-performance tungsten-lighting applications with an integrated dimmer. Using ETC’s Electronic Silent* (ES) technology and a convection-cooled design, this high-performance dimmer can be placed in acoustically- sensitive venues. By taking DMX control signals directly, this self-dimming tungsten fixture can now reside alongside LEDs and moving lights, allowing system designs to focus on switched power and data distribution instead of centralized dimming systems.

APPLICATIONS

• Applications requiring distributed dimming and position flexibility:
• Theaters
• Hybrid incandescent, LED and discharge systems
• Industrial productions
• Rentals
• Conference and exhibition centers
• Multi-use venues such as schools and meeting rooms

FEATURES

• ES Dimming technology
• Produces no lamp noise (exceeds all risetime specs)
• Electronics sound-pressure level less than 0dBA at 1meter
• Convection-cooled
• ANSI E1.20 RDM and ANSI E1.11 DMX512A
• Yoke-mount; Universal-mounting bracket included, direct-mounting on a fixture yoke in multiple orientations to accommodate maximum flexibility
• Local operation
• One-press dim to FULL for easy focusing (press again to release to DMX input)
• Up and down level control
• Returns to previous level after power loss
• No electrical assembly required: Ships as complete kit with burner assembly - just mount to the yoke and place lamp burner at the back of an existing fixture.
• Connectorized Edison power cable input
