Extend the (3) stacking legs 
Extend the stacking legs by turning 
them so that at least 1 inch of thread is 
visible on each. This clearance 
accommodates the up-or-down 
movement for aligning the images from 
stacked projectors. Extend all 3 legs 
equally (Figure 2.11). 
• If upright – extend legs on top 
projector (shown).  
• If inverted – extend legs on bottom 
projector. 
 IMPORTANT  
Extend the stacking legs 
equally by at least 1 inch. 
 
 
 
 
 
Loosen the rear stacking leg nuts 
On the rear stacking legs, loosen the nuts so the legs have some lateral movement for 
easier alignment with the stacking mounts on the other projector.

The safety pins must be removed from the 
stacking mounts so that the stacking legs can fit 
into the mounts (Figure 2.13).  
• If upright – remove the pins from the mounts 
on the bottom projector. 
• If inverted – remove the pins from the 
mounts on the top projector. 
 
 
 
Place top projector on bottom projector 
 WARNING  
Minimum of 2 people required. 
With one person on each side, lift the top projector on to bottom projector, aligning 
all three stacking points between projectors. Legs should fit inside stacking mounts. 
Align holes in (3) stacking mounts and (3) stacking legs. 
On each stacking mount, turn the adjusting wheel slightly until the hole in the top 
portion of the mount lines up with the hole in the stacking leg (Figure 2.14). 
NOTE: You can increase leverage by using a screwdriver in the holes.

 WARNING  
Failure to engage the safety lock could cause the 
projectors to separate and result in injury or death. 
Leg Nuts 
Before hoisting, firmly tighten the nuts on the (2) rear stacking legs (Figure 2.14). Or, 
if you are ready to align the projectors to one another, leave these nuts slightly loose 
until after the alignment. 
Repeat STEPS 1–9 for a third projector. 
 WARNING  
Never stack more than 3 projectors. 
Stacked projectors must be correctly aligned to one another so that the resulting 
display is optimized and as sharp as possible. If you are also hoisting the stack, hoist 
the stack into place first, then align. Lock all stacking hardware into place to maintain 
your alignment. 
 IMPORTANT  
Make sure the stacking legs have been extended 
by at least 1 inch, and are slightly loosened.

Align the centerlines of the grid 
Turn the (2) rear stacking mount 
wheels to move the top projector 
as necessary for well-aligned 
centerlines. Use a screwdriver in 
the holes around the rim of each 
adjusting wheel for better leverage 
and control. 
HOW TO MOVE THE IMAGE: 
Turned independently, each 
stacking mount acts as a pivot 
point for the opposite edge of the 
display (Figure 2.15). For 
example, turn the right mount to 
tilt the left portion of the image up 
or down, and turn the left mount to 
tilt the right portion of the image 
up or down. Turn together to raise 
or lower the top image like an 
offset adjustment, or turn the front stacker. 
IF THE CENTER LINES FORM AN “X”: This indicates that the projectors (and images) 
are slightly tilted in relation to one another. Turn one mount to raise one side, and/or 
turn the other mount to lower other side. See Figure 2.15. 
IF THE CENTER LINES ARE PARALLEL BUT MISALIGNED:  
• If centerlines are out by the same amount from top 
and bottom – use offsets (on top projector) to bring 
the centerlines into alignment. 
 
 
• If centerlines are parallel but 
others are not, turn the front 
stacking mount wheel to bring 
the centerlines into alignment. 
 
 
 
Align the edges of the grid 
With centerlines aligned, adjust zoom (top projector) to align the edges of its image 
with the other image. Then adjust focus. When aligned, all lines from the combined 
red/green grids will be yellow.   STEP 5 '

Front Screen Installations 
While there are two basic screen types, flat and curved, generally flat screens are 
recommended for this projector (Figure 2.17). Flat screens offer a gain of about 1 
with a viewing angle just less than 180°. Incident light reflects equally in all 
directions so the audience can see the display from various angles. Because of the 
low gain, flat screens are most effective when ambient lighting is reduced, although 
this difference may be negligible given the high brightness output from this projector. 
  
Figure 2.17. Audience Coverage with Flat Screen 
NOTE: Lenses for this projector are designed primarily for use with flat screens, but 
the projector depth-of-field range allows the lens to be focused on curved screens as 
well. While focus remains sharp in the corners, there may be significant pincushion 
distortion, primarily at the top of the screen. 
Rear Screen Installations 
There are two basic types of rear screens: diffused and optical . A diffused screen has 
a surface that spreads the light striking it. Purely diffused screens have a gain of less 
than 1. The main advantage of the diffused screen is its wide viewing angle, similar 
to that of a flat screen for front screen projection. Optical screens take light from the 
projector and redirect it to increase the light intensity at the front of the screen. This 
increase at the front reduces the intensity in other areas. A viewing cone, similar to 
that of a curved front screen installation, is created. 
To summarize, optical screens are better suited for brightly lit rooms where the 
audience is situated within the viewing cone. Diffused screens may be better suited 
when a wide viewing angle is required but there is low ambient room lighting. 
Screen size may vary from 4 feet (122 cm) to 45 feet (1372cm) diagonal, depending 
on the lens you are using. For instance, a 0.73:1 lens can produce a 5 foot (150 cm) to 
a 14 foot (548 cm) image size depending on the location of the projector, whereas a 
4.5-7.3:1 zoom lens produces an 8 foot (160 cm) to 40 foot (438 cm) image size. 
Choose a screen size appropriate for your lens and application. Keep in mind that if 
the projector will be used to display text information, the image size must allow the 
audience to recognize all text clearly. The eye usually sees a letter clearly if eye-to-
text distance is less than 150 times the height of the letter. Small text located too far 
from the eye may be illegible at a distance no matter how sharply and clearly it is 
displayed.   Screen T

Roadster/Mirage S+ User’s Manual 
Ideally, to fill a screen with an image, the aspect ratio of the screen should be equal to 
the aspect ratio of the image. The aspect ratio of an image is expressed as the ratio of 
its width to its height such as a 4:3 aspect. Standard video from a VCR has a 4:3 
aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-
foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m). 
Aspect ratio describes the proportion of the screen and is expressed as the ratio of 
width to height, such as “4:3” or “5:4”. Although image size and image aspect ratio 
can both be adjusted quickly through projector software, it is still a good idea to 
choose a screen aspect ratio that is most appropriate for your intended applications. 
Ideally, to exactly fill a screen with an image, the aspect 
ratio of the screen should correspond to the aspect ratio of 
the image, which depends on the source in use. For 
example, standard video from a VCR has a 4:3 ratio 
(approximately), whereas a high-resolution graphics signal 
typically has a 5:4 aspect ratio. By default, images from 
your projector will be as large as possible and will maintain 
their aspect ratio. 
The SXGA+ (1400 x 1050) aspect ratio for the Roadster S
+ 
and Mirage models is 4:3 (Figure 2.18). 
The high brightness of this projector is well suited for locations where ambient 
lighting might be considered less than ideal for projection. Even a typical room or 
large auditorium fully lit with ceiling lights and windows rarely requires special 
attention. Contrast ratio in your images will be noticeably reduced only if light 
directly strikes the screen, such as when a shaft of light from a window or floodlight 
falls on the image. Images may then appear washed out and less vibrant. 
In general, avoid or eliminate light sources directed at the screen. 
Other considerations and tips that can help improve your installation: 
• Keep the ambient temperature constant and below 35°C (95°F). Keep the 
projector away from heating and/or air conditioning vents. Changes in 
temperature may cause drifts in the projector circuitry that may affect 
performance. 
• Keep the projector away from devices that radiate electromagnetic energy such 
as motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers, elevators, etc. 
• Choose the best screen size for the application. Since more magnification reduces 
brightness, use a screen size appropriate for the venue but not larger than 
required. Installing a large screen in a small room is similar to watching 
television at a close range; too large a screen can overpower a room and interfere 
with the overall effect. A good rule of thumb is to be no closer than 1.5 times the 
width of the screen.
