The optical design of the DC1 is very forgiving, so minor deviations in this positioning or any
moderate warming around a projector vent will have no impact on image quality. In addition, note
that in a ceiling mounted system, the center of your projector beam will exit the projector lens below
center.
The DC1 will ultimately be aligned with the beam itself and not the projector lens.
As a
result, you should expect the DC1 to be centered below the projector lens and, ultimately, tilted
downward. Before final tightening of the mounting screws, refer to the “Final Adjustments” step
below.
1.
Remove the DC1 Lens Bracket From the shipping box. Securely attach the Lens Bracket to
the MTH1 shuttles using the eight M3x6mm brass screws and black washers included in the MTH1
kit. The Lens Bracket should be oriented so that its central threaded hole is aligned with the long slot
in the body of the MTH1 and that the forked arms are facing the screen.
2.
If using an AK attachment kit, position the MTH1 to the bottom of the installed AK Attachment
Plate so that the detailed side (front) of the MTH1 body is facing the projection screen. Insert each of
the four M3x16mm Phillips screws through a lock washer and flat washer from the MTH1 kit, through
the four “M” slots in the Attachment Plate and into the corresponding holes in the MTH1 body.
Tighten only to the point that the MTH1 is against the Attachment Plate but is still relatively free to be
oriented or “pivoted” in the “M” slots.
3.
Now carefully install the DC1 Lens into the Lens Bracket using the two ¼” #6-20 screws and
black washers with the included gold hex key. Proceed to “Final Adjustments” step below.
FINAL ADJUSTMENTS (ALL INSTALLATIONS)
1.
Turn the projector on with the DC1 Lens out of the projector beam. Set the horizontal lens
shift to neutral (if a feature of your projector) and then adjust the ceiling mount so that the 16:9 image
is in the exact center of and square to the screen, with a similar amount of image slightly over the top
and bottom screen borders. If the projector lens is not in the exact horizontal center of the screen you
may need to use a little horizontal lens shift for this purpose.
2.
Bring the DC1 Lens into the beam. Adjust the vertical position and tilt of the Lens so that the
projector beam is passing through the center of the Lens and so any residual pincushion distortion is
about the same at the top and bottom of the image. This will typically result in the DC1 Lens being
below the center of the projector lens and tilted slightly downward. Tighten the screws then lock the
lens in place by tightening the small silver set screw with the provided hex wrench.
3.
Adjust the rotation of either the ATH or MTH transport so that the left and right sides of the
image are an equal distance from their respective screen borders. Now tighten the Pivot Screw
(ATH) and also the four remaining screws holding the transport to the Attachment Plate.
4.
For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a 1.85:1
aspect ratio movie (Panamorph “out”) is just masked by the top and bottom of the screen border.
This way 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies should all be presented to fill the screen at a
constant height.
