INSTALLATION AND SETUP
Roadie 25K User’s Manual
2-45
If present, swing the anamorphic lens in position in front of the primary lens. It
should magnify in the horizontal direction only, stretching the image straight across
the screen—this requires that its aperture (visible within the lens) be vertically
aligned with the screen. If the image appears skewed, loosen the locking ring on the
anamorphic lens and rotate the lens as necessary until the wide image is horizontal.
1.
FOCUS PRIMARY LENS:
With the anamorphic lens in place, re-focus the primary
lens using focus knob. The goal is good focus at center and on all sides.
2.
FOCUS ANAMORPHIC LENS:
If horizontal focus in the image
needs improvement, focus the anamorphic lens too—rotate its
barrel as needed.
In rare instances, shipping and handling may affect the precise factory alignments of
one or more optical components—as a final step during installation, a trained installer
may want to adjust the fold mirror and/or convergence of the DMDs as described
here. In addition, for certain applications and sites you may prefer images having
increased contrast ratio and/or the widest possible color gamut, both of which require
the addition of internal optical components (sold separately) that will slightly reduce
brightness.
WARNING
Qualified service technician required.
FOR INCREASED CONTRAST RATIO:
If desired, the standard F# Aperture installed at
the factory can be replaced with an optional smaller aperture that improves contrast
ratio while slightly limiting brightness. Note that some lamps may be incompatible
with some apertures—use only the size(s) recommended for the lamp currently
installed in the projector. Follow the installation instructions provided with the F#
Aperture Kit.
NOTE: The size of any smaller aperture is clearly labeled along its top edge. The
factory-installed standard-size aperture (for maximum brightness) is not labeled.
FOR THE WIDEST COLOR GAMUT:
Install the Yellow Notch Filter (optional) inside the
projector, near the lens opening. Adjust to match a known standard, such as x=0.265,
y=0.690, or as desired. In applications where maximum brightness is preferred over
increased color gamut, do not add the Yellow Notch Filter (this is the factory default).
FOR MAXIMUM BRIGHTNESS:
Do not use either the optional Yellow Notch Filter or a
small-diameter high-contrast F# Aperture option in the projector. This is the factory-
default configuration. Also, make sure a standard high-brightness lens is present.
A convergence problem is evident when one or more projected colors
(red/green/blue) appears misaligned when examined with a proper convergence test
pattern—where normally the 3 colors should overlap precisely to form pure white
lines throughout the image, one or more poorly converged individual colors may
appear adjacent to some or all of the lines. A qualified service technician can correct
