If present, swing the anamorphic lens in position in front of the primary lens. It 
should magnify in the horizontal direction only, stretching the image straight across 
the screen—this requires that its aperture (visible within the lens) be vertically 
aligned with the screen. If the image appears skewed, loosen the locking ring on the 
anamorphic lens and rotate the lens as necessary until the wide image is horizontal. 
1. 
FOCUS PRIMARY LENS: With the anamorphic lens in place, re-focus the primary 
lens using focus knob. The goal is good focus at center and on all sides. 
2. 
FOCUS ANAMORPHIC LENS: If horizontal focus in the image 
needs improvement, focus the anamorphic lens too—rotate its 
barrel as needed. 
 
 
 
In rare instances, shipping and handling may affect the precise factory alignments of 
one or more optical components—as a final step during installation, a trained installer 
may want to adjust the fold mirror and/or convergence of the DMDs as described 
here. In addition, for certain applications and sites you may prefer images having 
increased contrast ratio and/or the widest possible color gamut, both of which require 
the addition of internal optical components (sold separately) that will slightly reduce 
brightness. 
 WARNING  
Qualified service technician required. 
FOR INCREASED CONTRAST RATIO: If desired, the standard F# Aperture installed at 
the factory can be replaced with an optional smaller aperture that improves contrast 
ratio while slightly limiting brightness. Note that some lamps may be incompatible 
with some apertures—use only the size(s) recommended for the lamp currently 
installed in the projector. Follow the installation instructions provided with the F# 
Aperture Kit. 
NOTE: The size of any smaller aperture is clearly labeled along its top edge. The 
factory-installed standard-size aperture (for maximum brightness) is not labeled. 
FOR THE WIDEST COLOR GAMUT: Install the Yellow Notch Filter (optional) inside the 
projector, near the lens opening. Adjust to match a known standard, such as x=0.265, 
y=0.690, or as desired. In applications where maximum brightness is preferred over 
increased color gamut, do not add the Yellow Notch Filter (this is the factory default). 
FOR MAXIMUM BRIGHTNESS: Do not use either the optional Yellow Notch Filter or a 
small-diameter high-contrast F# Aperture option in the projector. This is the factory-
default configuration. Also, make sure a standard high-brightness lens is present. 
A convergence problem is evident when one or more projected colors 
(red/green/blue) appears misaligned when examined with a proper convergence test 
pattern—where normally the 3 colors should overlap precisely to form pure white 
lines throughout the image, one or more poorly converged individual colors may 
appear adjacent to some or all of the lines. A qualified service technician can correct

as described on the color Convergence Instructions label provided inside the 
projection head. 
NOTE: Custom Convergence Kit required (available separately). 
If a corner or edge of an image is missing, this may indicate that the fold mirror has 
become misaligned with the rest of the optical system and cannot reflect all data 
properly. Correct as described below: 
1.  Locate the fold mirror access plate secured to the underside of the projection 
head, just below the lens. It has 2 access holes along the front edge, through 
which you can carefully adjust the fold mirror screws: 
• To raise or lower the 
image, adjust the 
screw closest to the 
left side (exhaust side 
of projector). 
• To move the image 
left or right, adjust the 
screw closest to the 
right side (lamp side). 
 
 
Proper fold mirror adjustment 
is shown at right, with the whole image 
well-centered between the projected 
edges of the integrator. 
 
 
 
NOTE: Protocols B-G are not supported in v1.1 software. Use “A” or “Wired” only. 
At manufacture every remote keypad is assigned “A” as its default protocolwhich is 
simply a collection of settings that determine how the keypad operates. Once 
assigned, this protocol remains in effect until it is changed—that is, a remote keypad 
will operate as it currently does until you change its protocol. Each IR remote can 
operate using one of 7 different protocols, or it can be set to a “wired” protocol when 
a cable is added for connecting the remote to the projector. Changing a keypad’s 
protocol is done via “hard-wired” jumper settings inside the keypad. 
The IR protocols A-G are generally used for multiple-projector applications. For 
example, you might want to change a keypad protocol if you need to control multiple 
projectors independently (Figure 2.51). When Keypad A operates under a different 
protocol than Keypad B (or others), each keypad communicates only with the 
projector(s) having a matching protocol defined in memory.    Fold Mirror Ad

NOTE: Matching the protocol on the projector to that of a keypad is done through a 
setting in the Communications submenu. See 3.8, Adjusting System Parameters and 
Advanced Controls for further information on how to define which protocol the 
projectors infrared sensors (rear and front) will recognize. 
 
 
Figure 2.51. Independent Keypads and Projectors 
The Roadie 25k’s standard IR remote keypad can be set to one of seven different 
protocols, “A” through “G”. To change protocol in the remote, follow Steps 1 
through 4. 
NOTE: Protocols B-G are not supported in v1.1 software. Use “A” or “Wired” only, 
both of which can be turned on or off. 
Step 1 
Unlatch and open the battery compartment on the back of the keypad as shown in 
Figure 2.52.

Step 2 
Find the 4 jumpers located along the latching side of the battery compartment. These 
jumper settings establish the remote keypad protocol so that the remote functions in a 
certain manner.   Remote Keypad

Step 3: Set the Jumpers 
Set the jumpers to match one of the protocols shown in Figure 2.53. Use tweezers or 
needle-nose pliers to remove and replace each jumper as necessary. 
• J1 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol. 
• J2 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol. 
• J3 jumper: Set between 1 and 2 or 2 and 3 as required for the desired protocol. 
• J4 jumper: For IR use, always set between pins 1 and 2 (see A-G below).  
 
Figure 2.53. Locating and Setting the Jumpers 
NOTE: Protocols B-G are not supported in v1.1 software. Use “A” or “Wired” only. 
Step 4 
Replace battery compartment cover. Plug into projector (wired keypad only) and test. 
NOTE: If you change any keypad to a new protocol and the projector stops 
responding, the projector may be set to a conflicting protocol. Use the projectors 
built-in keypad to access the Communications submenu. Under “Front IR” or “Back 
IR”, select the protocol that matches the new protocol of the keypad at hand. The 
projector should now respond properly. 
SHORTCUT METHOD: 
Unlike earlier Christie projectors and keypads, there is no shortcut method for 
changing a keypad’s protocol through a special sequence of keystrokes. You must 
change the internal jumper settings. 
If desired, you can convert an IR remote keypad into a wired remote keypad and vice 
versa. Set the jumpers as shown in Figure 2.53, and add or delete the cable and 
batteries as required. The cable with appropriate connector is supplied with the 
projection head. 
TO CHANGE FROM INFRARED TO WIRED: 
• Remove battery compartment cover from back of keypad. 
• Remove batteries. 
• Wait 1-2 minutes.   Convertin

• Plug the keypad cable (supplied) into the empty battery compartment. 
Pack with foam as an internal strain relief. Make sure that the battery 
cover is notched smoothly to accommodate the cable without pinching it. 
• Set keypad protocol to “wired” jumper setting (refer back to Figure 
2.53). Make sure to set jumper #4 between pins 2 and 3 as shown in the 
last example (shaded). 
• Replace battery compartment cover. 
• Plug into the 3-pin XLR port at the rear panel of the projector. 
TO CHANGE FROM WIRED TO INFRARED: 
• Unplug the keypad from the projector. 
• Open the keypad back and unplug the keypad cable. 
• Wait 1-2 minutes. 
• Install batteries (see Section 4). 
• Set jumpers according to the desired IR protocol (refer back to Figure 
2.53). Make sure to set jumper #4 between pins 1 and 2 as shown for all 
remote protocols. 
• Replace battery compartment cover.

in dusty/dirty environments. Check condition monthly. See 6.4, Replacing the Lamp 
& Filter for complete instructions. 
Ballast Breaker (on/off) 
The breaker on the lamp ballast serves two purposes: 1) it is a power switch for the 
Roadie 25K ballast 2) it protects against over-current conditions of 50A or more. The 
breaker must be ON in order to enable normal Roadie 25K system power-up and 
operation. If faulty or major excessive AC is detected, the breaker will “trip” to OFF 
in order to prevent damage. Try moving the breaker ON again—if the breaker 
continues to trip OFF, this indicates a major fault and the AC problem must be 
resolved. Possible causes might include shorts, damage to lamp cables, or very 
excessive AC. 
NOTE: This switch does not power up the projector or start the lamp. You must press 
 (POWER) on the keypad. 
The ballast’s internal fan indicates whether or not the breaker/switch is on. There is 
no other indicator. Lights on the ballast indicate only that the ballast is plugged in. 
Channels for FredFrame 
Adjustment mechanisms (part of Christie’s FredFrame
) insert and secure into these 
channels under the projector, enabling the projector to be hoisted, flown, and/or 
stacked. Consult complete installation instructions supplied with the frame kit. 
Control Panel 
(REAR OF PROJECTOR) 
The rear control panel includes the built-in keypad, IR sensor, 2-digit error code 
window, and the LCD status display.

Exhaust Duct 
Connect the projector’s 8” top exhaust hole to a rigid duct (provided). Add Christie’s 
50/60 Hz heat extractor at the opposite end of the duct so that adequate airflow (600 
cf/m) is maintained near the top of the projector. The vane switch in this vent will 
prevent start-up and/or trigger a shutdown if airflow is inadequate. See Section 2, 
Installation & Setup. In a stack of projectors, Christie’s Side-Venting Duct Adapter 
must be installed to redirect exhaust rising from the bottom projector’s exit duct. 
Input Panel 
Connect input sources and a variety of communication cables here, all described in 
2.5, Connecting Sources and 2.6, Connecting Communications. If desired, connect an 
optional remote keypad having a small headphone jack type connector. 
Lamp 
Use one of the following lamp sizes (note ballast requirements): 
Lamp Size Ballast Required 
2.0 kW  Single-or-3-Phase 
3.0 kW  Single-or-3-Phase 
4.5 kW  3-Phase 
6.0 kW  3-Phase NOTE:: The single-phase ballast is not yet available. 
Keep the lamp door closed and locked for all normal operation. Trained technicians 
(only) can access the lamp via security key. Complete lamp details and warranties are 
provided in Section 6, Specifications. 
Lens Mount & Anamorphic Lens Mount 
The lens mount secures and seals a primary zoom lens within the projector and 
provides manual adjustment of focus, zoom and offset. Adjacent to the primary 
mount, an optional anamorphic lens mount may be added, providing a mechanism for 
positioning a 1.25x anamorphic lens in front of the primary lens. Such a lens 
horizontally spreads a pre-squeezed image back into its wider 2.39:1 “scope” image, 
and is most typically used in side-masking displays. 
Leveling Feet 
Turn the 4 adjustable feet to increase or decrease projector height and/or tilt as 
needed. For most installations, the projector will likely be slightly inclined to match 
screen tilt  – this reduces the amount of vertical offset required. See 2.3, Projector 
Position & Mounting. For flown projectors, the feet can be removed. 
DC Power Cables 
Heavy-duty DC lamp cables between the ballast and the projection head are 6½ – 100 
feet (2-30 meters) in length. The ballast, projection head and heat extractor fan all 
include their own line cords. 
Projection Head 
The projection head houses all critical illumination and optical components as well as 
the DLP
 processing technology responsible for combining light and incoming 
source signals into brilliant high-resolution digital displays. Source inputs connect to 
the input panel on the side of the projector. Projector function is controlled via the

integral keypad, remote keypad, or other communication link from a controller. The 
projection head is closed and locked for normal operation. 
Rear Connection Panel 
The rear connection panel links the projection head to AC power, to an external 
RS422 controller, and to the other Roadie 25K components (ballast, extractor fan and 
a tethered keypad).
