PROCESSING & PROJECTION: The CP2000-X accepts a variety of cinema or
DVI-compatible “non-cinema” signals for projection on front screens typical in a
commercial theatre or other large screen applications. High brightness light is
generated by a short arc Xenon lamp, and then modulated by three Digital
Micromirror Device (DMD) panels responding to incoming data streams of
digitized red, green or blue color information. As these digital streams flow from
the source, light from the responding “on” pixels of each panel is reflected,
converged and then projected to the screen through one or more front lenses,
where all pixel reflections are superimposed in sharp full-color images.
STACKING & RIGGING: A projector secured in the optional FredFramecan be
stacked and, if desired, flown with another framed projection head using the
Roadie 25K/CP2000-X Stacking and Rigging Kit and standard rigging techniques
to secure the two frames together. Each frame provides precision roll, pitch and
yaw adjustments of the projector for precision image alignments. Corresponding
lamp ballasts can be located up to 100 feet away, flown or not.

This section explains how to install, connect, and optimize the projector.
NOTE: Unless otherwise specified, illustrations apply for either CP model and may
not always show the rear-mounted TPC.
Follow these steps for quick setup of the projector in a basic front mount position.
Position the Projection Head
Locate the projection head at an appropriate throw distance (projector-to-screen
distance) and vertical position. See 2.3, Projector Position and Mounting. Make sure
that the projector is level from side-to-side, and do not invert. Locate the lamp ballast
so that its 4 cables can reach the rear of the projection head.
Install the Touch Panel Controller
(TPC)
Attach the Touch Panel Controller,
pre-assembled with its ball joint base
and mounting arm, to the matching ball
joint base secured at the rear of the
projector. Plug the TPC into the TPC
port on the projector’s rear connector
panel using the standard 3-ft. cable
provided.
Alternatively, mount the TPC in a
remote location up to 50 feet away and
attach to the rear of the projector using the optional long-distance cable.

HEAD-TO-BALLAST: Connect all 4 ballast cables—two DC power cables, and 2
communication/control cables—between the projector rear and lamp ballast.
BALLAST-TO-AC: See Figure 2.4. Connect the ballast’s integral line cord to your AC
supply (you may have to first modify the plug for the AC at your site).
NOTE: Before connecting the ballast to AC, a qualified electrical technician must
make sure the ballast’s plug type and Input Power Range Switch match the line
voltage available at the site. Remove the lamp ballast cover to access the switch and
determine its setting—toggle left for 200 VAC supplies, toggle right for 400 VAC
supplies (factory default=200 VAC). Modify the plug type as necessary—as a delta
load with safety ground, it has no neutral.
Confirm that the ballast’s 3-phase status lights are on and that the adjacent
voltmeter displays an acceptable AC level for your ballast and region. See
Section 6, Specifications for details. Then set the ballast AC on/off switch to ON
and listen for the internal cooling fan start-up.
NOTE: There is no other indication of “ballast ON” status.

CP2000-X User Manual 2-5
020-100031-01 Rev . 1 (03-2009)
SET THE LAMP TYPE: Before powering
up the projector and igniting the lamp,
the installer must define in projector
memory the size of lamp installed,
otherwise you risk severely
overdriving or underdriving a lamp.
At the TPC, go to the Admin: Lamp
menu (password required). Enter the
size of the lamp currently installed in
the projector (factory default = 2.0
kW). See Section 3, Operation if you
need help using the TPC menus. Also
record the lamp type on the “Lamp
Installed” label.
SET THE CABLE LENGTH: Still in the
Admin: Lamp menu, use the “Cable Length (m)” text box to record the length of
high-voltage DC cables connected between your lamp ballast and projection head.
This value regulates the voltage drop that occurs over distance, and ensures that
adequate voltage reaches the lamp. Particularly in projectors rented for temporary
installations, the setting may have to be changed from its last use. Adjustment range
is 2-30m (6½-100 ft.) in 1m increments.
Ignite the Lamp and Select the Source
At the TPC Main menu, press the lamp button and hold for two seconds to ignite the
lamp. Press the desired channel button on the Main menu. The source will be
displayed according to pre-defined factory defaults for this channel. Adjust or apply
new settings as described in Section 3, Operation.
Adjust the Lens
Turn the focus knob to sharpen the image. Adjust the zoom ring on the lens to
increase or decrease image size. If desired, use the horizontal and/or vertical offset
knobs to shift the image location. For other lens functions, refer to 2.8, Offset and
Boresight Alignment and 3.8, Working With the Lens.
Although the CP2000-X is carefully engineered to deliver an exceptional quality
high-brightness, high-resolution output, your final display results could still be
compromised if the projector is improperly installed. This subsection discusses issues
to consider before proceeding with a permanent installation. Read through for an
understanding how good positioning will help ensure optimized images at any site.
Front Screen Installations
This projector is intended for use with flat or slightly curved screens, front or rear,
ranging from about 5 meters (16 ft.) to 25 meters (82 ft.) wide. Although flat screens
generally offer a low gain similar to a matte white wall paint—approximately 1 with
a viewing angle just under 180°—and are considered most effective when ambient
light is low, this difference in gain may be negligible given the very high light output
from this projector. In addition, incident light reflects equally in all directions so the
audience can see the display from more acute viewing angles. See Figure 2.7.

Figure 2.7. Audience Coverage with a Flat Screen
NOTE: CP2000-X high-contrast lenses are designed primarily for use with flat
screens, but the projector’s depth-of-field range allows the lens to be focused on
mildly 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 rear 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 rear screens take
light from the projector and redirect it to increase the light intensity at the front of the
screen. This reduces it in other areas, and creates a viewing cone similar to that of a
curved front screen installation.
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 (image size) may be up to 145 feet across, depending on your lens and
ambient light level. Choose a screen size appropriate for your lens and application.
Keep in mind that if the projector will be used to display much 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. In
other words, small text that is simply located too far from the eye will be illegible no
matter how sharply and clearly it is displayed.
NOTE: Screens/images are most described according to their horizontal (
 )
screen width. Aspect ratio is also specified if it is anything other than 4:3 (see
below). The older “diagonal screen size” typically used for 4:3 displays such as
televisions and monitors is less commonly used for large projection screens.

4.3 – 6.0:1 zoom 2.5-35 ft.
5.5 – 8.5:1 zoom 2-27 ft.
Aspect ratio describes the proportion of the display and is expressed as the ratio of
width to height, such as “5:4” or “16:9”. Typical aspect ratios range from 1.25 to
2.35—the higher the value, the wider or “less square” the image. See Table 2.2.
Table 2.2. Typical Aspect Ratios
Application Aspect Ratio
SXGA 1.25 (5:4)
35mm filmstrip 1.32 (4:3)
NTSC Video / XGA 1.33 (4:3)

HDTV Video 1.78 (16:9)
Letterbox Video / “Flat” 1.89 (2048 x 1080)
Cinemascope 2.35
Although image size and aspect ratio can be adjusted using projector controls, it is
still ideal to use a screen with an aspect ratio that closely matches your likely source
material. You can then more easily fill the screen with the image without restricting
either image size or content. For example, standard video from a VCR has a 4:3 ratio
(approximately) and can fill a 4:3 screen without side-to-side stretching, whereas a
high-definition signal with a 16:9 aspect ratio is largest on a 16:9 screen.
Figure 2.8. Aspect Ratios: Images vs. Screens
As shown in Figure 2.7, an obvious mismatch between source material and screen is
characterized by “black bars” on both sides of the image (if the screen is wider than
the source material) or above and below the image (if the source material is wider—
typically called a letterbox display). The black bars are unused display pixels and, in
many installations such as theatres, are masked or hidden behind panels or curtains.
Alternatively, if the area of unused pixels is considered minimal, you may prefer to
use the projector’s software control to slightly stretch the image either horizontally or
Screen Aspect Ratio

vertically—enough to utilize the remaining pixels while not noticeably distorting the
image.
Displaying Both ‘Flat” and “Scope”
As an example, two standard types of displays common in theatres—flat and scope—
differ in their width-to-height aspect ratio as shown below:
Figure 2.9. Typical Wide Formats
Achieving either of these displays from a variety of incoming source material (that
may or may not be in a format matching that of the screen) depends on lenses, proper
settings in the projector, and certain room conditions.
See also 4.2, Image Formats.
The extraordinary brilliance of this projector is certainly 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 stray 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, which 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.
Your installation site, the available screen, and ambient lighting all affect where the
projector should be positioned. In addition, both throw distance (the distance
between the projector and screen) and vertical position (the height of the projector in
relation to the screen) must be determined for every new installation. Both depend on
Ambient Lighting

the screen size and lens type you are using. Make sure that the room can
accommodate the required location of the projector for the chosen screen size.
With the projection head secured on a suitable cart, position the unit so that the front
bezel is less than 2 feet from the theatre’s port window wall, or 3 feet if the optional
auxiliary lens mount will be added. Center the projector with the theatre screen ()
if possible (see Figure 2.10 A). If forced to be off-center (such as when a film
projector is already present), try to optimize aim as shown in Figure 2.10 B. This will
slightly increase side keystoning, but will minimize horizontal lens offset required.
NOTE: Unlike film projectors, it is best to keep the projector lens surface as parallel
to the screen as possible, even if it is significantly above the screen center.
Figure 2.10. Centering (AERIAL VIEWS)
Note that when a particularly short throw distance combines with a very wide screen,
you may have to forfeit some aim and stay more parallel to the screen. In such cases,
some lens offset can reduce the keystone distortion.
Later, when your projector is up-and-running, adjust precise image geometry and
placement as described in 2.7, Basic Image Alignment.
Throw distance is the distance between the projector and the screen (Figure 2.11).
For any installation, placing the projector at an accurate throw distance is necessary
in order for the image size to closely match your screen – the farther the projector is
from the screen, the larger the image. With zoom lenses, you’ll want to know the
approximate minimum and maximum image sizes possible from a given throw
distance so that the most appropriate lens is installed at the site (throw distance /
screen width = throw ratio of lens).
Calculating Throw Distance
Once you know the screen size and lens type present, calculate the required throw
distance by using the appropriate formula provided in Table 2.3.
NOTES: 1) If your projector is tilted up or down in relation to the screen, typical in
large venues and/or elevated installation, throw distance still represents the smallest
measurement between the screen and front bezel. 2) Remember that throw distances
are calculated from the screen to the front bezel of the projector rather than its foot
centers. To figure throw distance from foot centers, add 8.74” (22.2 cm).

width of the screen multiplied by the type of lens you are using. For example, if you
are using a 1.25:1 lens, the proper throw distance value will be approximately 25%
more than that of the full screen width. Once you know your screen width and lens,
you can estimate throw distance needed. Or, if you know the available throw distance
beforehand, you can determine what images sizes are possible with a given zoom
lens.
IMPORTANT: For proper placement in any installation, use the throw distance
formula provided for your lens. In addition, please keep in mind that due to lens
manufacturing tolerances for lens focal length, actual throw distance can vary ±5% or
more between lenses described as having the same throw ratio.

Table 2.3. provides the throw distance formula for each high-contrast lens. Once you
know what size screen you wish to fill, use the formula for the corresponding lens to
calculate the best throw distance. All formulas are in centimeters (cm).
NOTE: Minimum throw distance is 15 feet for all lenses except as noted.

NOTES: 1) Make sure to use HORIZONTAL screen width in all formulas. 2) Throw
distance can often be exceeded with negligible loss of focus. 3) Throw ratios,
formulas and throw distances apply to both standard and optional high-contrast
lenses.
Refer to the offsets shown here for help in determining how high or low to install the
projector in relation to the center of the screen, and/or how far off to one side.
VERTICAL POSITION describes the elevation of the projector in relation to the screen.
For many typical large venue rental/staging installations and theatres, the projector
will be above screen center. An ideal vertical position helps ensure that 1) images
will be accurately rectangular in shape rather than distorted into a keystoned shape
with non-parallel sides, and 2) focus and brightness will remain optimized.
Vertical position of the image can be manually offset—that is, placed higher or lower
in relation to lens center—using the vertical offset knob on the lens mount. Starting
with no offset, the 2048 x 1080 image from this projector can be moved by a
maximum distance of 540 pixels, resulting in all of the image displayed above or
below lens center (Figure 2.12).
VERTICAL TILT describes the angle of the projector in relation to the screen. Ideally,
the projector should be inclined to match the screen, so that the face of the lens and
the surface of the screen are parallel to each other. See Tilting and Special
Orientations, below.

Figure 2.12. Vertical Offset Range
NOTE: 1) Assumes full 2048 x 1080 display. 2) Recommended offset range can
sometimes be exceeded, however this may affect image quality. 3) Due to
manufacturing tolerances, an offset range can vary ±5% or more between lenses
described as having the same throw ratio, between projectors, and with any
lens/projector combination. 4) Simultaneous horizontal and vertical offset can limit
the adjustment range of each, as can long throw distances.
ALTERNATIVE METHOD OF DESCRIBING VERTICAL OFFSET: Offset can also be
specified as the distance traveled from lens center (such as 270 pixels) and expressed
as a percentage (270 pixels=50%) of half of the image height. This concept of image
movement is illustrated in the example below:
