Shaping the Beam
The beam can be shaped using the four shutters or with a pattern.
The Source Four Mini LED has four
shutters: left, right, top, and bottom. Each
shutter can be pulled out or pushed in to
create the desired beam shape.
Color Frame Holder
The Source Four Mini LED comes equipped with a 2 ¾” or 70mm color frame,
which is a metal frame used to hold color media (often referred to as gel) in front of
the lens. The color frame holder is equipped with a retaining clip that prevents the
color frame from falling out.
1” Diameter
Pattern Projection
The Source Four Mini LED has a pattern holder slot
on the top side of the shutter barrel, in front of the
shutter. It accommodates a E-size (37.5mm with a
25.4mm image area) pattern holder.
Use an optional donut in the color frame holder to
enhance pattern projection.
When the slot is not in use, a small sheet metal cover
secured with a Phillips screw prevents light leakage.
Step 1: Use a Phillips screwdriver to loosen the
screw on the slot cover. Do not remove the
screw.
Step 2: Slide the cover completely forward to
expose the slot.
Step 3: Insert the pattern holder.
Step 4: Slide the slot cover back toward the
shutters until it meets the pattern handle.
Leave enough space to move the handle.
Step 5: Secure the slot cover by tightening the
screw.
