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

to refine other display parameters, if necessary. See 3.5, Using Inputs and

Channels if you want to work with other source inputs or defined channels.

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

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.

INSTALLATION AND SETUP

2-6 Mirage 22000/4000/6000User’s Manual

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.

Figure 2.5. Poor Screen Placement

Ideal Room Li

htin

INSTALLATION & SETUP

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.
