1. A Guide by Mr. Doucette SOURCE FOUR E.R.S.

2. THE FIXTURE THAT CHANGED THE LIGHTING INDUSTRY (FROM ETC WEBSITE) Source Four combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality lenses, for the coolest beam on the market. That means your gels, patterns, and shutters last longer and your performance space stays cooler. No other light offers such optical brilliance. Source Four's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field. The EDLT lens tube option for 19º, 26º, 36º and 50º field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections.

3. PRODUCT FEATURES 5º, 10º, 14º, 19º, 26º, 36º, 50º, 70º and 90º field angles Rated up to 750W Super-efficient HPL lamp Faceted dichroic reflector removes 90% of IR heat from beam Interchangeable lens tubes Rotating barrel ± 25º Three-plane stainless-steel shutter blade assembly Tool-free lamp adjustment Insulated rear handle

4. BUT WHAT DOES ALL THAT MEAN? The Source Four (S4) did in fact revolutionize the entertainment industry. It is the number one conventional stage light (Non-Moving) in the world. From Broadway to Six Flags to Jordan’s furniture, where there is entertainment the S4 is there. The reason is simple - it has an advanced reflector and advanced lenses so that a 750w bulb actually looks as bright as a 1000w bulb; and a 575w bulb looks as bright as a 750w bulb. With the Source Four, you get the same light output with using less energy and expelling less heat.

5. IT IS ALSO EXTREMELY VERSATILE The lens tube is interchangeable. That means a wide flood lens can easily and quickly be swapped out for a tight spot light lens. The lenses have different degrees printed on them:  The number corresponds to the angle of light that exits the lens tube.  5º, 10º, 14º, 19º, 26º, 36º, 50º, 70º and 90º are the field angles offered by S4 The most common for theatre use includes:  10º is a good lens angle for a tight spot light  19º, 26º, 36º are good for breaking your stage down into lighting areas.  50º is a great wash/ fill light- lots of coverage. (Four or five of these will fill a space)

7. THE C- CLAMP- ATTACHES THE LIGHT TO THE PIPE

8. SECURE THE C-CLAMP AND SAFETY Make sure the Yoke Bolt is secured to the yoke. Make sure the pipe bolt is tightened down and the body is sitting on the pipe The Pipe Bolt, Pan Screw, and Yoke Bolt should all be tightened with a crescent wrench Use a safety to go through the yoke and over the pipe as a back up.

9. YOKE AND TILT SCREW On the Side of the Yoke there is a screw with a handle. This allows the instrument to tilt up and down on the pipe. It can easily be hand tightened. It usually only needs a ¼ - ¾ turn to loosen the yoke. Do Not loosen the handle too far!

10. SHUTTERS The shutters allow you to decrease the amount of light coming through the instrument by altering the shape of the beam. Concerns:  Be careful not pull the shutters all the way out.  Make sure you never have all the shutters closed when you have a light on at full.  When moving a light to a new location, or keeping it in storage make sure all shutters are pushed in as to not get damaged.  The right shutter will effect the left side of the beam. The bottom shutter will effect the top side of the beam, and so on.

11. SOURCE FOUR BODY The Source Four body has an accessory slot by the shutters, this can hold a Gobo holder or an iris. Make sure the Accessory slot is always pointing to the ceiling so that accessories don’t fall out due to gravity. Accessories should only be placed in lights that have already been hung. The Source four body also has a star shaped screw about halfway down the instrument. This screw allows you to easily spin the barrel up to 25 degrees. Make sure not to loosen this screw too much and always secure it after changing angle.

12. LENS TUBE The Lens Tube has a slot for two Gobo Holders. The Lens tube also has a screw that allows the Lens to slide out to be swapped. Never swap out a lens while people are underneath you. Loosening this screw a quarter to a half turn (¼ - ½) also allows you to slide the lens tube back and forth. This motion will change the focus of the beam from hard focus to soft focus. Make sure this screw is tightened after adjusting focus.

13. GEL FRAME When you place a Gel Frame into the Gel Frame Holder Slot on the lens barrel tube, make sure the gel frame sits into all three brackets and the sliding gel frame lock is secured.

14. LAMP HOUSING The Gold Screw will allow you to take the lamp housing off. The Black Screws allow you to change the angle and position of the lamp in the reflector. The Bulb or Lamp you can use is an HPL 575watt or an HPL 750watt.

15. ADJUSTING THE LAMP

16. REPLACING THE LAMP 1.Turn off the light and unplug the circuit. 2.Loosen the gold screw while holding onto the lamp housing. 3.Remove the lamp housing by holding on to the insulated handles (Be careful could be Hot ) 4.Pinch retaining metal wire together and swing up. 5.Wiggle out old lamp. 6.Put in new lamp by only touching silver base. DO NOT TOUCH NEW LAMP BULB ! The oils on your fingers will ruin the bulb. 7.Swing retaining metal wire back down and secure the lamp. 8.Carefully replace the housing unit into the body and tighten the gold screw. 9.Plug in the Circuit. 10.Turn on the instrument.

17. HANGING THE INSTRUMENT 1.Loosen the Pipe Bolt of the C Clamp 90% of the way. This ensures you do not have any problems getting the C-clamp over a larger pipe. 2.Identify where the accessories slot and Gel Frame Holder Lock is on the instrument. These should point to the ceiling so that nothing slides out due to gravity. 3.Place the C-Clamp on the pipe keeping a hand on the Yoke. 4.While holding the yoke, finger tighten the Pipe Bolt until you can no longer turn it. 5.Attach the safety going through the yoke and over the pipe. 6.Tighten down the Pipe Bolt, pan screw, and yoke bolt using a Crescent Wrench. 7.Loosen the Tilt Screw Handle on the yoke a ¼ to a ½ turn and angle the light at the desired degree. 8.Pull all the shutters out carefully. 9.Plug into the circuit. 10.Turn the light on from the board.

18. STRIKING THE INSTRUMENT 1.Turn Off the light and push the shutters all the way in. This protects them from being bent. 2.Return all jumper cables, gobo, gobo holders, gels, gel frames and other accessories to their designated storage locations. 3.Unplug the fixture. Secure the cable, by wrapping it around the fixture, so that it will not catch on anything as the fixture is moved. 4.Release the safety cable and secure it. Hold onto the yoke after the safety is off. 5.Loosen the C-Clamp and remove the fixture from the pipe.  Don't leave the fixture unsecured on a grid or catwalk where it can fall and injure people below. Likewise, don't leave it on the floor where it becomes a trip hazard for you or others.
