8 Source Four CE User Manual
English
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.
Note:
Because the Source Four luminaire aperture is 7.62 cm wide, ETC recommends
using A-size gobos for maximum effectiveness.
Note:
Enhanced Definition Lens Tubes (EDLT) provide for a crisper gobo projection.
