Using Soft Focus diffuser and gobo pattern

From the Source Four LED Profile v1.8.2 User Manual, page 18' "Install a Soft Focus Diffuser"

To clean up edge effects, use the soft focus diffuser in the A-size pattern holder. If combining the
diffuser with a pattern, put the diffuser behind the pattern. The soft focus diffuser allows you to
maintain sharp focus of the pattern while eliminating edge effects. The diffuser is intended for Source
Four LED fixtures only.
A permanent install kit is available.

1: Install the diffuser into an A-sized pattern holder.
2: Install a pattern in front of the diffuser, if needed.
3: Insert the pattern holder and diffuser into the pattern holder slot, making sure the writing on the
diffuser faces the front of the fixture.
