Source Four™ HID • 3
Color frame retaining clip
The color frame holder is equipped with a spring-loaded retaining clip that prevents color
frames and accessories from falling out (
Figure 3 ).
1. Release the retaining clip by pushing it sideways while gently pulling backwards.
2. Insert the color frame.
3. Lock the retaining clip by pushing sideways while gently pushing forward.
Shaping the beam
You may shape the beam with the shutters, 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 (
Figure 4 ).
Note: Because the Source Four HID gate is 3.12 inches. ETC recommends using
A-size patterns for maximum pattern effectiveness.
Use an optional donut in the accessory holder to enhance pattern projection. Donut
diameter range should be 2.5 to 2.75 inches.
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 (
Figure 5 ).
1. Use a Phillips screwdriver to loosen the screws on the drop-in iris slot cover. Do
not remove the screws.
2. Slide the cover completely forward to expose the slot.
3. Insert the iris or motorized pattern device. For an iris, install the flat side toward
the shutters and make sure that the iris handle extends from the slot.
4. Slide the slot cover back toward the shutters until it meets the iris handle. Leave
enough space to move the iris handle.
5. Secure the drop-in iris slot cover by tightening the screws.
WARNING! Make sure all color frame accessories are locked in
position with the retaining clip before hanging the Source Four HID.
