INTRODUCTION
1-2 Mirage 2000/4000/6000 User’s Manual
Mirage 2000/4000/6000 models accept data/graphics and video input signals for
projection on to front or rear flat screens. High brightness light is generated by an
internal Xenon arc lamp (500W in Mirage 2000, 700W in Mirage 4000, and 1200W
in Mirage 6000), then modulated by three DMD (digital micromirror device) panels
that provide digitized red, green or blue color information. Light from the “on” pixels
of each panel is reflected, converged and then projected to the screen through a single
front lens, where all pixels are perfectly superimposed as a sharp full-color 2D or 3D
image.
Mirage 2000/4000/6000 models include an infrared (IR) remote keypad, line cord, a
9/64” hex socket ball driver, and a User’s Manual. Make sure that you have all these
items, and note that purchasers also receive a Warranty Registration Card–complete
this card and return it directly to the manufacturer as soon as possible.
Figure 1.1. Components
The models are identical except for their power levels and lamp wattage.
Whether the projector is under warranty or the warranty has expired, Christie’s
highly trained and extensive factory and dealer service network is always available to
quickly diagnose and correct projector malfunctions. Service manuals and updates
are available to service technicians for all projectors.
Should you encounter a problem with the projector and require assistance, contact your

Installation & Setup
Mirage 2000/4000/6000 User’s Manual 2-1
This section explains how to install and set up your projector. If you are familiar with the projector and want to
quickly set it up for temporary use, follow the Quick Setup instructions below.
NOTES: 1) The lens is not installed for shipping. For instructions on how to install or replace a lens, refer to 4.5,
Replacing the Lens. 2) This section assumes that the optional video decoder module is installed.
Follow these steps for quick setup of the projector in a standard floor mount position.
Position the Projector
Set the projector at the expected throw distance (projector-to-screen distance) and
vertical position. See 2.3, Projector Position and Mounting and Appendix E. Make
sure that the projector is level from side-to-side (see 2.7, Leveling) and lens cap is off.
Connect a Source
Locate the main input panel at the rear of the projector. The lower left area, labeled
INPUT 1, accepts an RGB input via BNC connectors. The upper right area (assuming
a video decoder is installed) accepts a composite video at
INPUT 3 or S-video input at
INPUT 4. Connect your source to the appropriate panel connectors.
Connect the Line Cord to AC Power
Connect the projector’s line cord to the AC receptacle at the lower right rear corner of the
projector and to proper AC. The Mirage 2000 requires input power of 100-240 VAC, 50-
60 Hz @ 9 amps (@ 100 V). The Mirage 4000 requires input power of 100-240 VAC, 50-
60 Hz @ 11.5 amps (@ 100 V). The Mirage 6000 requires input power of 200-240 VAC,
50-60 Hz @ 8.5 amps (@ 200 V). Use the line cord provided with the projector. See
Section 5.
WARNING
Do not attempt operation if the AC supply and cord are not
within the specified voltage and power range. See Section 5.
Turn the Projector ON
Using either the built-in or remote keypad, press Power* and hold for approximately 1
second to turn the projector on (or press Power* ON ). Let the projector warm up for
about five minutes. The POWER LED, located in the lower right corner of the rear
input panel, should glow a steady green.
Select a Source
Using either the built-in or remote keypad, press
Input1
,
Input2
,
Input3

Although this projector delivers a high brightness quality output, final display quality
could be compromised if the projector is not properly installed. This subsection
discusses issues you should consider before proceeding with a final installation. Even
if you do not intend to use the projector in a fixed and permanent installation, this
subsection will help you to better understand what you can do to enhance display
performance.
Never lift or suspend a projector by its feet or any other component.
Remove the lens and securely wrap hoisting cabling and safety straps around the
entire projector. Whether inverted or not, attach to the proper Christie ceiling mount
only. Never suspend or “fly” this model.
NOTE: Mirage 2000/4000/6000 projectors cannot use a Christie Hoisting/Stacking
Kit for hoisting into place.

Front Screen Installations
While there are two basic screen types, flat and curved, generally flat screens are
recommended for this projector. 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 2.2. 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 which 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 reduces it 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 be from 5 to 40 feet diagonal, depending on the lens you are using.
For instance, a 1.2:1 lens can produce a 5 to 25 foot image size, whereas a 4-7:1
zoom lens produces an 8 to 40 foot image size. Choose a screen size which is
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 recognizes text 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.
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. Standard video from a VCR has a 4:3 aspect ratio. For example,
Screen T
yp
e'
Screen Size '

INSTALLATION & SETUP
Mirage 2000/4000/6000 User’s Manual 2-5
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” (see right). 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 which 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, with
the exception of graphics sources, will maintain their aspect ratio.
NOTE: With a few exceptions, sources with less than 1280 x 1024 resolution have a
4:3 aspect ratio. The normal aspect ratio for 1280 x 1024 sources is 5:4.
Using a 5:4 Screen
With one exception, XGA images will—
by default—resize to fill an SXGA (5:4)
screen. The exception is that video signals
will retain their aspect ratio, as shown in
Figure 2.3. In this case, fill the screen by
increasing Vertical Stretch to slightly
expand the image to the top and bottom
edges of the screen. For details, see 3.6,
Adjusting the Image.
Using a 4:3 Screen
If you are using a 4:3 screen (but producing 5:4 images), images will—by default—
slightly overlap the screen vertically. To remedy, reduce Vertical Stretch so that the
“too tall” 5:4 image no longer spills over the top or bottom of the screen (Figure 2.4).
This control eliminates the need for simply moving the projector farther from the
screen, which would result in black borders for all sources. See 3.6, Adjusting the
Image.
NOTE: The Vertical Stretch adjustment may soften the image slightly, but is not
noticeable in most cases.

The high brightness output of this projector is certainly well suited for locations
where ambient lighting is less than optimum for projection, yet there are still many
simple things you can do to optimize your installation.
Visiting a movie theater can give you an idea of what makes an ideal projection
environment. Walls, floors and furnishings are dark and matte finished. A projection
room should not have white reflective ceilings or non-directional lighting such as
fluorescent lights. The white ceiling spreads light, making the room appear brighter.
Keep lighting and reflections to a minimum.
If it is not possible to eliminate fluorescent lights, consider using incandescent spot
lighting or parabolic reflectors ("egg crates") to direct light down to the floor. Light
dimmers or rheostats allow further control.
Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have windows,
make sure that window coverings are opaque and overlapping — some window
coverings are designed to provide up to 100 percent blockage of outside light.
Ideally, the material should have a matte finish.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2.5 shows an
installation where poor screen placement allows too much unwanted light to enter the
screen. In Figure 2.6, screen and the projector are positioned so that unwanted light is
minimized.

Mirage 2000/4000/6000 User’s Manual 2-7
Figure 2.6. Better Screen Placement
Even with all lighting removed it is still possible that room reflections within the
room can slightly degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to the
screen. Again, keep reflective surfaces to a minimum.
Here are some other considerations and tips which can help you improve your
installation:
•Ventilation is an important factor when preparing a projection room. The ambient
temperature should be kept constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature can
cause drifts in the projector circuitry which may affect performance.
•Keep the projector away from devices which radiate electromagnetic energy such
as motors and transformers. Common sources of these are slide projectors,
speakers, power amplifiers, elevators, etc.
•For rear screen applications, less space is required if a mirror is used to fold the
optical path.
•Choose the right screen size for the application:
◊As screen size increases, magnification increases and reduces brightness.
Select a screen size which is appropriate for the venue, but not larger
than that required.
◊Installing a large screen in a small room is similar to watching television
close up; too large a screen can overpower a room. A good rule of thumb
is to be no closer than 1.5 times the width of the screen.
◊Larger screens require greater attention to lighting conditions.
•When laying out the projection room, consider positioning the projector and
screen in a manner which will achieve maximum audience coverage and space
efficiency. For example, placing the screen along the larger wall in a rectangular
room will reduce audience coverage. Figure 2.7 shows two examples of how
audience coverage is maximized.
Other Considerations '

INSTALLATION AND SETUP
2-8 Mirage 22000/4000/6000User’s Manual
Figure 2.7. Screen Locations for Maximum Audience Coverage
Installation type, screen type, and lighting all affect where the projector is 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 the screen size and lens type
you are using. Make sure that the room can accommodate the required position of the
projector for the chosen screen size.
Throw distance is the distance between the projector's front feet and the screen. For
any installation, an accurate throw distance must be determined in order for the
image to be of the right size for your screen–the farther the projector is from the
screen, the larger the image.
NOTE: If your projector is tilted in relation to the screen, as is sometimes the case
for large venues or elevated installations, throw distance still represents the smallest
measurement between the screen and front feet.
Throw distance is roughly equal
to the horizontal width of the
screen multiplied by the type of
lens you are using. For example,
if you are using a 0.8:1 lens,
proper throw distance will be
approximately 0.8 xthe screen
width. Once you know your
screen size and lens, you can
estimate throw distance needed
(see example in Figure 2.8).
IMPORTANT: For proper
placement in an installation,
always refer to the throw distance formula and/or graph for your lens as listed in
Appendix E. Keep in mind that due to lens manufacturing tolerances for lens focal
length, actual throw distance can vary ±5% between lenses described as having the
same throw ratio.

(SEE APPENDIX E)

INSTALLATION & SETUP
Mirage 2000/4000/6000 User’s Manual 2-9
THE VERTICAL POSITION of the projector in relation to the screen also depends on the
size of the screen and the lens type. Correct vertical position helps ensure that the
image will be rectangular in shape rather than keystoned (having non-parallel sides)
and that image focus and brightness both remain optimized.
In addition, vertical position of the image can be offset—that is, moved up or done—
either by turning the top knob on the front of the projector (the one nearest to the IR
sensor) in non-motorized projectors, or through software in motorized projectors.
Offsets range up to 130%, depending on the specific lens, whether it is motorized or
not, what amount of zoom is in effect and whether or not you are also offsetting
horizontally.
See Table 2.1 for the maximum percentage of the image that can be displayed above
or below the center of each type of motorized lens. These image offsets are also
illustrated in Figure 2.9.
NOTE: Shown are approximate motorized offset ranges—manual offsets standard in
Mirage 2000/4000/6000 may differ.

NOTES: 1) If you cannot raise or
lower the image enough using
mechanical vertical offsets, try
adjusting V-Position in the Size
and Position menu (see 3.6,
Adjusting the Image). 2) If the
image becomes keystoned or
exhibits uneven brightness, the
projector may simply be too high
or low in relation to the screen. 3) Recommended offset ranges can be exceeded,
however this may affect image quality. 4) Simultaneous horizontal and vertical offset
limits the adjustment range of each.
THE HORIZONTAL POSITION of the image can be offset—that is, shifted left or right
of lens center—either by turning the bottom knob on the front of the projector (the
knob farthest from the IR sensor) in non-motorized projectors or through software in
motorized projectors. The maximum horizontal offset for lenses that can be installed
in this projector is shown in Figure 2.10. This value expresses the maximum
percentage of the image that can be projected to one side of the lens center (roughly
77%, depending on the lens).

Figure 2.10. Maximum Horizontal Offsets (ALL LENSES)
For typical front or rear floor mounts, mount the projector on a
secure table or cart. Take care with a mobile cart—avoid
sudden stops, excessive force and uneven surfaces that may
cause the projector and cart combination to overturn.
The table or cart should be reasonably level. Fine adjustments to the projector level
can be made by adjusting the height of the projector legs; refer to 2.7, Leveling for
details.
Special Mounting
Note that projector can be rotated and mounted at any vertical angle—i.e., you can
tilt the face of the projector up or down as much as desired for your installation. The
side-to-side tilt, however, must not exceed 15° (see Figure 2.11). This limit ensures
that the arc lamp in the projector operates properly and safely. Always make sure that
exhaust air from the projector does not vent towards the lens, otherwise you may
detect heat waves in your projected image.
Figure 2.11. Horizontal and Vertical Tilt Ranges
You must use the proper ceiling mount fixture (and/or stacking kit, if applicable) for
your projector. For more information, contact your dealer.

In rear screen applications where space behind
the projector is limited, a mirror may be used
to fold the optical path. See right. The position
of the projector and mirror must be accurately
set—if considering this type of installation, call
your dealer for assistance.
The rear panel of the projector provides standard input panels to which you may
connect a variety of sources. See Figure 2.12–the lower left area (INPUT 1) typically
accepts an RGB signal from an external RGB source, or it can also be used for YPbPr
signals or additional video sources. The upper right panel–the optional Video
Decoder Module–accepts only composite video at INPUT 3 or S-video at INPUT 4 from
devices such as VCRs, laser disk players or DVD players. There are also several
optional interfaces available for connecting other sources at INPUT 2. Such an option
installs in the upper left area, just above INPUT 1.
NOTE: For all connections, use only high-quality shielded cables.

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources, typically to
an RGB source such as VGA, SVGA, XGA, Mac, PowerMac, DEC, Sun, SGI and
others. This projector supports multiple sync types with RGB signals: sync-on-green,
composite sync, and separate H & V syncs.
NOTE: Depending on the source, you may need a custom adapter cable with BNC
connectors at the projector end and a different type of connector at the other (such as
a 15-pin "D" connector for computer sources). Contact your dealer.
Connect the SYNC BNC input(s) first. Then connect the red, green and blue source
outputs to the RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses
sync-on-green, only the red, green, and blue connections are required. If the source
provides a composite sync output, connect it to the SYNC input labeled HOR/COMP. If
the source provides separate horizontal and vertical sync outputs, connect horizontal
sync to the SYNC input labeled HOR/COMP and connect vertical sync to SYNC input
labeled VERT. See Figure 2.13.
NOTES: 1) If for some reason the projector fails to recognize as an RGB signal,
specify this Color Space option within the Image Settings menu. See 3.6, Adjusting
the Image. 2) To connect YPbPr signals–such as from DVD or analog HDTV sources–to
INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals later in this
section.

Connect a YPbPr signal (component video) to INPUT 1 as shown in Figure 2.14.
Figure 2.14. Connecting YPbPr Signal
NOTES: 1) If, for some reason, the projector fails to recognize a YPbPr signal,
specify this Color Space option within the Image Settings menu. See 3.6, Adjusting
the Image. 2) Do not connect digital component signals (known as YCbCr) to INPUT
1. Use the appropriate digital interface installed at INPUT 2..
The video decoder input panel provides simultaneous connection of both a composite
video source (INPUT 3) and an S-Video source (INPUT 4).
If connecting a composite video source, use the Composite BNC connector or the
RCA phono jack at INPUT 3–do not use both as inputs. See Figure 2.15.
NOTE: If you want to loop a composite signal through to another projector or
display device, see Video Loop Through later in this section.

INSTALLATION AND SETUP
2-16 Mirage 22000/4000/6000User’s Manual
The video decoder input panel provides simultaneous connection of both a composite
video source (INPUT 3) and an S-Video source (INPUT 4).
If connecting an S-Video source, use the 4-pin mini DIN connector or the Y and C
BNC connectors (luma and chroma) at INPUT 4–do not use both as inputs. See Figure
2.16.

NOTE: If you want to loop an S-video signal through to another projector or display
device, see Video Loop Through below.

INSTALLATION & SETUP
Mirage 2000/4000/6000 User’s Manual 2-17
To loop a single incoming video signal input (connected at the video decoder)
through to another projector or display device, use the empty connector(s) adjacent to
this same input as described below.
Composite Video Loop Through
CONNECTIONS: See Figure 2.17. From your source, connect a composite video signal
to INPUT 3 using either the small phono plug or the adjacent BNC. Connect a second
cable from whichever INPUT 3 connector is free to one of the composite video inputs
of the next display device or projector. Continue this looping method for each
projector, using either the phono plug or the adjacent BNC as input into INPUT 3,
then using the other connector as an output (i.e., loop through). Whether you use the
BNC or the phono plug as input or output depends on the type of cable you have on
hand and what type of connectors are on each end.
VIDEO TERMINATION: In the Video Options submenu, make sure “Video
Termination” is checked for the final projector only. All other projectors must have
this option unchecked in order for the signal to continue. For other types of display
devices in the chain, typically a “Hi-Z” switch position is needed.
