projection in large screen applications. High brightness light is generated by a shortarc Xenon lamp, then modulated by three DMD (Digital Micromirror Device) 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.

BALLAST-TO-AC: See Figure 2.2. Connect the ballast’s integral 3-phase 30 amp line

cord to your AC supply—you may have to modify the plug for 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.

Screen Types '

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 2.4.

Figure 2.4. Audience Coverage with a Flat Screen

NOTE: Roadie 25K 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.

Roadie 25K User’s Manual 2-5

INSTALLATION AN D SETUP

Rear Screen Installations

There are two basic types of rear screens: diffused and optical. A diffused rear scre en 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 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

Screen Size

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.

Screen Aspect Ratio '

NOTE: Screens with aspect ratios (proportion) of 4:3 are typically specified by diagonal size, but screens having other aspect ratios—such as the 2048 x 1080 of the Roadie 25K— are usually specified by their horizontal width. See below.

Table 2.1. Matching Lenses to Screen S ize

Lens Type Screen Width (<—>)

1:1 fixed 14-145 ft.

1.25 – 1.45:1 zoom 10-121 ft.

1.45 – 1.8:1 zoom 8-102 ft.

1.8 – 2.4:1 zoom 6-83 ft.

3.0 – 4.3:1 zoom 3-49 ft.

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.

Roadie 25K User’s Manual

INSTALLATION A ND SETUP

Although image size and aspect ratio can be adjusted u sing projec tor sof tware, it i s 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 is largest on a 16:9 screen.

Figure 2.5. Aspect Ratios: Images vs. Screens

As shown in Figure 2.5, 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 most installations, 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 vertically— enough to utilize the remaining pixels while not noticeably distorting the image.

Using a Cinema “Flat” Screen (1.85 aspect ratio)

By default, source signals closely matching the projector’s 2048 x 1080 (a.k.a., 1.89) display area will fill this area accordingly. Signals with lower aspect ratios will automatically scale to be as large as possible while maintaining their original aspect ratio. For details on resizing behavior, see 3.7, Adjusting 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 2.6. Typical Wide Form ats

Achieving either of these displays from a variety of incoming source material (that may or may not be in the same format) depends on proper settings in the projector as well as certain room conditions.

Projector Variables: Electronic and Anamorphic Resizing

The native resolution of the projector (1.89) closely matches the aspect ratio of “flat” source material (1.85). Wider scope material, however, may be “squeezed”

Figure 2.7. Typical Method for Achieving “Scop e”

Masking Options

In order to conveniently present different types of incoming data— for example, flat vs. scope—on a single screen, you can use physical masking to cover the unused edge(s) of the screen. These movable panels are most commonly installed along the top edge of the screen, changing the height of the screen but not its width, and are most frequently used in permanent installations such as theatres. The screen shown in Figure 2.8 at right

Figure 2.8. Top Masking for Scope Images

also has a bottom mask.

• Add masks for “scope” displays

• Remove masks for “flat” displays

Alternatively, masks may be installed at each side of the screen in order to change the width of the screen but not its height.

• Add masks for “flat” displays

• Remove masks for “scope” displays

In some cases, the room will have both side and top/bottom masking installed. This arrangement is the most flexible of all.

Ambient Li

hting '

Other Considerations '

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 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 which 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 which 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.

2.3 Projector Position and Mounting

Throw Distance '

Installation type, 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 the screen size and lens type you are using. Make sure that the room can accommodate the required location of the projector for the chos en scr een size.

Throw distance is the distance between th e 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).

2-10

Roadie 25K User’s Manual

INSTALLATION A ND SETUP

Figure 2.11. Estimating Throw Distance: Example

NOTE: If your projector is slightly tilt ed in relat ion to the scre en, typ ica l for large venues and/or elevated installati ons, throw dis tan ce still repr esen ts the smal les t measurement between the screen and projector.

As shown in Figure 2.11, throw distance is approximately equal to the horizontal width of the screen multiplied by the type of lens you are using. For example, if you are using a 1:1 lens, proper throw distance will be approximately the same as screen width. Once you know your screen width and lens you can estimate throw distance needed. Or, if you know throw distance, you can determine what images sizes are possible with a given zoom lens.

Vertical & Horizonta

Position

IMPORTANT: For proper placement in any installation, use the throw distance

formula provided for your lens (Appendix D). In addition, please keep in mind that due to lens manufacturing toleranc es for len s foc al le n gth, actu a l throw distance can vary ±5% or more between lenses described as having the same throw ratio.

For complete throw distance information, consult Appendix D. 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 rental/staging installations, the projector will be above screen center. An ideal vertical position helps ensure that images will be accurately rectangular in shape rather than distorted into a keystoned shape with non-parallel sides, and that image focus and brightness both remain optimized.

NOTE: Proper vertical position is recommended, although vertically keystoned images (i.e., those with sloping sides) can be corrected in software. See Section 3.

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).

NOTES: 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 DE S C RI BING VERTICAL OFFSET: Offset can also be

specified as the distance traveled as a percentage (270 pixels=50%) of half of the image height

from lens center (such as 270 pixels) and expressed

. This concept of image

movement is illustrated in the example below:

when displaying at less than the minimum size (see 3.7, Adjusting the Image). If images remain keystoned or exhibit uneven brightness, the projector may simply be too high or low in relation to the screen. Relocate for optimized performance.

THE HORIZONTAL POSITION of the image can

be manually offset—that is, shifted left or right of lens center—by using the horizontal offset knob on the lens mount. Starting with no offset, the 2048 x 1080 image from this projector can be moved by a distance of 410 pixels, resulting in up to 70% of the image displayed on one side of lens center (Figure 2.14).

Note that the positioning shown at right is often mistakenly referenced as “70% offset” but it is not—it is 40% offset derived as 410/1024 x

100. A 70% offset is explained below and shown in Figure 2.15.

ALTERNATIVE METHOD OF DESCRIBING HORIZONTAL OFFSET: Horizontal offset

can also be specified as the distance

Range

traveled from lens center and expressed as a percentage of half of the image width

. For example, an offset spec of 70% means a centered image can be moved by a distance of 717 pixels, resulting in 85% of the image projected to one side of lens center and 15% on the other. See right.

Specification

For front projection without suspending, mount the projector on a strong supporting structure or cart. Take special care if using a mobile cart—avoid sudden stops, force and uneven surfaces that may cause the top-heavy cart to lurch and overturn.

Make sure your mounting structure is reasonably level, then adjust one or more projector feet as necessary to fine-tune.

INSTALLATION AN D SETUP

WARNING

Do not invert this pr ojector.

Adjusting the Feet

For installations on a floor or suitable supporting structure, a single projection head should rest firmly on its feet. There is no need for the FredFrame unless stacking with another Roadie 25K, or unless you decide to rig and fly the projector.

To adjust the height and level of the projector, extend or retract the feet by rotating them.

Tilting and Special ' Orientations

See Figure 2.16.

Tilting

For any installation, you can tilt the front end of the projector up or down as much as 15° (see right).

Likewise, side-to-side tilt must not exceed 15° (see Figure 2.17 below). This limit ensures safe lamp operation and proper position of the liquid cooling reservoir in the projector.

WARNING

Tilt only as shown.

2.4 Installing a Lens, Lamp & Cooling

Install Lens(es) '

Before or after you have positioned the projector in its permanent or temporary location, install the remaining components: the lens, lamp and external extractor fan.

Primary Lens

1. Orient your primary lens with its

label at the top (see right). Fully insert it straight into the lens mount opening all

the way back without turning.

With the lens fully back, it will seat properly within the lens mount.

2. Lock the lens assembly in place with lens clamp DOWN.

3. Secure lens safety ring, and tether to projector (not required if projector is floormounted).

NOTES: 1) The lens seals the projection head, preventing contaminants from entering the area of main electronics. Never attempt to operate the projector without a lens installed. During transport

Extractor Fan and Duct

For any Roadie 25K with any lamp, install the Christie extractor fan and duct to pull warm exhaust air from the projector at a minimum rate of 600 CFM. Use either the 6in. or the 6-ft. duct in one of the configurations shown below:

2-18

Figure 2.21. Extractor Fan Configurations

(MANDATORY SAFETY CABLING NOT SHOWN)

Roadie 25K User’s Manual

INSTALLATION A ND SETUP

Direct exhaust as necessary to keep ambient air temperature within operating spec (see Section 6, Specifications). If the projector is used for extended periods, particularly in a confined space, routing to the outside of the building may be required. In all cases, maintain at least 600 CFM at the projector’s top exit port:

Table 2.3. Airflow Requir ements

Lamp (kW) Minimum Exhaust Airflow Rate

2.0 600 ft3/min.

3.0 600 ft3/min.

4.5 600 ft3/min.

6.0 600 ft3/min.

INSTALLATION: Follow the installation guidelines provided below, securing all

components in the order that best suits your site and installation requirements.

WARNING

Do not operate the p rojector wi thout the Christi e

Extractor components installed.

1. INSTALL DUCT ON PROJECTOR: See

Figure 2.23 below. Align either the 6inch or 6-foot duct at the projector’s top exit port, twisting to secure “flaps” over projector pins. Confirm that 1) there are no obstructions or “kinks” within the ducting, 2) all air intake areas of the projector are clear and exposed, and 3) the vane switch at the exit duct moves freely.

Figure 2.22. Securing Extr ac tor to

Duct

INSTALLATION AN D SETUP

2. ADD EXTRACTOR: See Figure 2.22.

Connect the other end of the duct to the Christie heat extractor/blower, twisting to secure “flaps” over pins on the fan. Make sure that the grille of the fan faces down

. For longer

end

exhaust runs at your site, add extractors/boosters as necessary—the vane switch at the projector’s top exit port will trigger a projector shutdown if the airflow is inadequate. To prevent possible transfer of fan vibration to the image, do not mount the extractor directly on the projector—include at least 6” of duct.

IMPORTANT

Do not exceed 6-ft. duct length

without adding additional extract ors.

Figure 2.23. Securing Duct to

Projector

3. To suspend the projector/fan assembly, always use appropriate rigging hardware

and secure to adequate support structures at your site. The Christie 6-ft. duct-with-fan weighs approximately 22 lb. The Christie 6-in. duct-with-fan weighs approximately 15 lb.

Use third-party extractors only if the minimum of 600 CFM airflow can be maintained.

SECURE SAFETY CABLES: Three safety cables are provided, and are all mandatory

whenever the fan/duct assembly is suspended. These cables prevent components

from falling if your rigging equipment fails. Figure 2.24 shows the safety cable

required between the cooling assembly and projector in any installation, flown or

not. Attach remaining safety cables between the 1) duct and fan, and 2) fan and

supporting structure.

5. CONNECT TO POWER: Connect the line cord of the extractor fan to the “Ext rac tor Fan” outlet on the rear panel of the projector. Use appropriate extension cords if necessary. The fan will power-up with the projection head, and will run for a 10 minute cool-down period after the projection head is powered off.

Roadie 25K User’s Manual 2-21

INSTALLATION AN D SETUP

CALCULATE CFM in 8” DUCT: Use an air flow meter to measure the ft/min or ft/sec

where the duct connects to the projector (measure at this end only). Then multiply the reading by the cross-

sectional area of the 8” duct (0.34) to calculate the cubic feet/min airflow. The formula is:

Measured linear ft/min x 0.34 = CFM

NOTE: If the duct becomes significantly blocked—or if a fan fails—the projector should trigger an error message before becoming overheated or unsafe. Regardless, check airflow regularly

WARNING

Never disable a vane switch. Attempting to operate the

projector without monitoring airflow can result in

dangerous overheating of the projector.

Side-Venting Duct (Adapter)

NOTE: Available early 2005.

2.5 Connecting Sources

All stacks require a special side-venting duct adapter between projectors, otherwise the top projector blocks exhaust from the top of the bottom projector. This Roadie 25K Exhaust Adapter Kit is required on any bottom projector in an upright stack of two.

Liquid Cooling

During operation, a closed loop of flexible tubing circulates liquid coolant from a small reservoir to critical electronic components located near the front of the projection head. The coolant (a 50/50 mix of distilled water and ethylene glycol) should fill slightly more than half of the reservoir to ensure adequate circulation. The reservoir, which is located in the igniter compartment, is factory-filled and does not require draining for transit. Check regularly.

Sources connect to the Input Panel located on side of the projector closest to the lens. See Figure 2.25.

The upper left corner (

INPUT 1) typically accepts an RGB signal from an external

analog RGB source, or it can also be used for YPbPr signals. Just beneath these BNCs, the DVI-I connector ( computer. Connect analog composi te vid eo at devices such as VCRs, laser disk players or DVD players. At
