Configuration - Adjusting System Parameters And Advanced Controls - Christie Roadster S+14K-J User Manual

Optical Aperture
The optical aperture inside the projector controls the diameter of the light beam passing through the system.
With a fully open aperture (slidebar default of "0"), the maximum amount of light passes through for
maximum brightness in your images. Increase the slidebar setting to reduce the aperture diameter and
maximize contrast ratio instead. Performance of aperture depends on the lens in use.
NOTE: Optical Aperture (when present) also appears in the Lamp menu.
Aperture Manual Adjustment
A variable position manual aperture is present on the 1.2:1 and 1.1:1 lens. It may be used together with the
internal electronic aperture to increase the contrast ratio; noting a slight decrease in brightness when it is used.
It is recommended for highest brightness operation, under normal conditions, the manual aperture is to be left
open. See Figure 3-30 Aperture Manual Adjustment
positions. NOTE: The lock/unlock dial position allows you to open the aperture at a desired position and lock
it in place.
