Shaping the beam
The beam can be shaped using the shutters (see Figure 8 ), a gobo, an optional drop-in iris, or by
rotating the barrel.
Gobo Projection
The gobo holder slot is on the top side of the barrel and in front of the shutters. It accommodates
A-size, B-size and glass gobo holders (see Figure 7 ).
Use an optional donut in the accessory holder to enhance gobo projection. Donut diameter range
should be 6.35 cm to 6.98 cm.
Drop-In Iris Slot
The drop-in iris slot is located on the top of the barrel and in front of the gobo holder slot. It
accommodates either a drop-in iris or a motorized gobo 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 Phillips screwdriver to loosen the screws on the drop-in iris slot cover. Do not
remove screws.
Step 2: Slide the cover completely forward to expose the slot.
N o t e : Because the Source Four luminaire aperture is 7.62 cm wide, ETC recommends
using A-size gobos for maximum effectiveness.
N o t e : Enhanced Definition Lens Tubes (EDLT) provide for a crisper gobo projection.
