Basic Assembly 3
Color frame holder
The color frame holder is equipped with a spring-loaded retaining clip that prevents color frames
and accessories from falling out. See Figure 2.
Step 1: Release the retaining clip by pushing it sideways while gently pulling backwards.
Step 2: Insert the color frame.
Step 3: Lock the retaining clip by pushing sideways while gently pushing forward.
WARNING:
Make sure all color frame accessories are locked in position with the
retaining clip before hanging the Source Four.
Note:
The performance of saturated colors may be less than desirable in any theatrical
lighting fixture, especially when equipped with a 750w lamp. For best results,
always use high-quality color media rated for high-temperature use.
ETC’s optional Gel Extender, part # PSF1029, will provide maximum color media
life. The use of any gel extender accessory may limit the coverage of any wide-
angle lens or beam setting.
A variety of heat shield products is also available from many color media
manufacturers. Follow the manufacturer’s instructions for the use of these
products.

Replacing the HPL Lamp
A lamp must be installed before you use the fixture.
Step 1: Disconnect power to the Source Four before installing the lamp.
Step 2: Loosen the knurled bolt on the back of the lamp housing and pull the housing out.
Step 3: Holding by the base, remove the HPL lamp from its box.
Step 4: Align the flat sides of the lamp base with the retention brackets on either side of the
socket as shown in Figure 3.
Step 5: Push down on the lamp base until the lamp seats firmly. When properly installed, the top
of the lamp’s base will be even with he top edges of the retention brackets.
Step 6: Press lamp retaining clip across lamp base to secure.
Step 7: Reinstall the lamp housing by aligning the bolt hole and tightening the knurled bolt.
Note:
Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115-, 120-, 230-, and 240-volt HPL lamps are available. See Fixture information,
page 2. Operating HPL lamps above their rated voltage reduces lamp life and can
cause premature lamp failure.
WARNING:
Let the lamp cool before replacing.
CAUTION:
Use caution when installing or replacing any lamp.
When installing/replacing lamp, be sure to point the lamp away from your face and
away from others before inserting it firmly into the assembly.
This may prevent injuries if the lamp should break.
Note:
To avoid premature lamp failure, do not touch the lamp glass. If you do, clean it
carefully with isopropyl alcohol and a clean lint-free cloth. Allow to dry before
operation.
CAUTION:
Improperly installed lamps cause premature lamp failure and socket problems.

Adjustments 5
Adjustments
Centering lamp and adjusting the field
The two concentric knobs located on the lamp housing allow you to align the lamp and adjust its
field. See Figure 4. The outer knob centers the lamp within the reflector. The inner knob adjusts the
lamp’s field.
Step 1: Turn on the Source Four and aim it at a flat surface. Adjust the barrel to create a hard
edge.
Step 2: Unlock and loosen the outer knob by turning it counterclockwise.
Step 3: Gently move the outer knob from side to side and up and down until the lamp is centered
within the reflector.
Step 4: Once the lamp is centered, turn the outer knob clockwise to lock it in place.
Step 5: Finally, turn the inner knob either clockwise or counterclockwise to achieve an optimum
flat field. See Figure 5.
Selecting the field angle and focusing the beam
Step 1: Press the locking lever push button and lift the locking lever to unlock the focus dial as
shown in Figure 6.
Step 2: To reduce the field angle, rotate the focus dial clockwise. To enlarge the field, rotate the
dial counterclockwise.

Step 3: Once the desired field angle is established, slide the light baffle forward to soften or
backward to sharpen the edge.
Step 4: Once the field and edge are established, press the locking lever to lock the focus dial into
position.
Shaping the beam
The beam can be shaped using the shutters (see Figure 1), a pattern, an optional drop-in iris, or by
rotating the barrel.
Pattern Projection
The pattern holder slot is on the top side of the barrel and in front of the shutters. It accommodates
A-size, B-size and glass pattern holders (see Figure 7).
Use an optional donut in the accessory holder to enhance pattern projection. Donut diameter range
should be 2.5” to 2.75”.
Drop-In Iris Slot
The drop-in iris slot is located on the top of the barrel and in front of the pattern holder slot. It
accommodates either a drop-in iris or a motorized pattern device. When the slot is not in use, a
small sheet metal cover secured with two Phillips screws prevents light leakage (see Figure 8).
Step 1: Use a screwdriver to loosen the screws on the drop-in iris slot cover. Do not remove
thumbscrews.
Step 2: Slide the cover completely forward to expose the slot.
Step 3: Insert the iris or motorized pattern device. For an iris, install the flat side toward the
shutters and make sure the iris handle extends from the slot.
Note:
Because the Source Four aperture is 3 inches wide, ETC recommends
using A-size patterns for maximum pattern effectiveness.

Step 4: Slide the slot cover back toward the shutters until it meets the iris handle. Leave enough
space to move the iris handle.
Step 5: Secure the drop-in iris slot cover by tightening the screws.
Rotating the barrel assembly
Step 1: Loosen the barrel rotation knob directly behind the shutters on the underside of the
reflector housing (see Figure 9). Do not remove the barrel rotation knob.
Step 2: Rotate the barrel to the desired position (up to 25° in either direction from the centered
position).
Step 3: Once the barrel is positioned, tighten the barrel’s rotation knob to lock it in place.
Adjusting the C-clamp
The C-clamp attaches the fixture to the mounting pipe and allows you to adjust the position of the
fixture once it is mounted (see Figure 10).
Step 1: Tightly fasten the C-clamp to the yoke with the provided yoke bolt and lock washer.
Step 2: Place the C-clamp on mounting pipe, then tighten the pipe bolt to secure it.
Step 3: Loosen the C-clamp pan screw and rotate the yoke to the desired position.
Step 4: Tighten the pan screw to lock the fixture..
CAUTION:
Tighten C-clamp pipe bolt to 15-20 ft./lbs. (approximately finger tight plus up to
one-quarter turn). Do not exceed 25 ft./lbs. Do not use excessive force.
Tighten the yoke pivot bolt to 5-10 ft./lbs. (approximately finger tight plus up to
one-eighth turn). Do not exceed 15 ft./lbs. Do not use excessive force.

the fixture is mounted (see Figure 11). To change the height position, perform the following steps.
Step 1: Remove the yoke locking knobs, washers, and hex bolts from either side of the fixture.
Step 2: Raise or lower the fixture to the desired position within the yoke.
Step 3: Reinstall the yoke’s hex bolts, washers, and locking knobs.
Step 4: Tighten the yoke knobs to secure in position.
Setting the angle within the yoke
Step 1: Loosen the yoke locking knobs (see Figure 12). Do not remove them.
Step 2: Tilt the fixture to the desired position.
Step 3: Tighten the yoke locking knobs to secure in position.
