Note that the two menus differ only in their user interface, so use whichever menu 
best suits your needs and application. 
• Color Adjustments by X,Y
 — Enter known x/y coordinates from the 
chromaticity graph. 
• Color Saturation
 — Adjust color slidebars and judge image color by eye or 
meter. 
A user-defined color “adjustment” can be applied for a source by selecting the 
desired “User” option in the “Select Color Adjustment” list accessed in the Advanced 
Image Settings menu. 
COLOR ADJUSTMENT BY X,Y: Use 
this submenu if you want to alter, 
add or copy a color gamut (i.e., 
“color adjustment”). Controls in 
this menu define the precise hue of 
each primary color component 
(red, green, blue, and white) used 
to generate the millions of colors 
produced in displays. The x/y 
coordinates for each color define 
its location on the standard CIE 
chromaticity graph (see Figure 
3.23)—changing either or both of 
these numbers will change the hue 
of the color, and relocate the 
“triangle” for possible colors. For 
example, changing the x/y 
coordinates for red will either 
move the color closer to 
orange or closer to violet, 
which will in turn affect all 
displayed colors having a red 
component. Adjust the 
slidebars or enter new 
specific coordinates as 
desired to define or change 
up to four “User” color 
gamuts needed for your 
environment and 
applications. Apply at any 
time in the Advanced Image 
Settings menu. 
NOTE: Keep new x,y 
coordinates within the 
original color gamut triangle 
shown here. 
PROCEDURE FOR X,Y ADJUSTMENTS:  See 3.12, Using Multiple Projectors.

COLOR SATURATION: Use this 
submenu if you do not have 
specific color coordinates in mind 
and will simply judge color 
performance by eye or meter. Like 
the Color Adjustment by X,Y 
submenu, each color control 
actually defines new x/y 
coordinates for that color and 
changes its hue—it is just a 
different interface. 
Adjust the hue of each primary 
color (red, green, blue, and white) 
by using more or less of it in 
relation to the other colors. Apply 
at any time in the Advanced Image Settings menu. 
NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates 
shown in the Color Adjustments by X,Y submenu. These x/y coordinates will remain 
stable for this “User” gamut until they are changed again via either menu. Values 
displayed in the Color Saturation menu, however, will likely fluctuate as you use the 
projector, and will be different when you return to this menu at some point in the 
future. These floating changes do not affect the x/y coordinates or gamut. 
Test Pattern 
Choose the desired internal test 
pattern to display, or select OFF to 
turn off a test pattern. 
Alternatively, use the 
Te s t key for 
cycling through test patterns. 
Test Pattern Grey Level 
Set the desired level of gray for 
displaying in the full gray field test 
pattern. 
Freeze Image 
Enter a check mark to freeze (stop) an image at a single frame. This diagnostic tool is 
useful if you need to examine in detail a still version of an incoming image that 
cannot be “frozen” at the source. For example, in moving images it is sometimes 
difficult to observe artifacts such as external deinterlacing/resizing and signal noise. 
Remove the checkmark to return back to normal. 
Color Enable 
Select which color or colors you want to see. This is useful while working with color 
temperature, input levels or other special setup parameters. Colors can also be 
enabled/disabled by entering the corresponding function code listed on the back of 
the standard remote keypad. 
Odd Pixel Adjustment

Roadie 25K User’s Manual 3-47 
When using certain RGB sources, you may need to adjust the normal gain or offset of 
odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide) 
“checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Although 
offset and gain slidebars can be adjusted individually and manually, using the Level 
Detector simplifies this process (see Figure 3.26): 
1) Use an external analog native-sized continuous grayscale test pattern with at least 
256-levels. 
2) Turn “Level Detector” on. 
3) Set “Level Value” to ~200. The image should now be black-and-white (or black-
and-one color, if you use “Color Enable” function). 
4) Adjust offset. Half of the pixels will move, the other half will not. 
5) Adjust until the two transition regions overlap. The stripe of noise will be 
minimized, defined by the value in the slidebar. 
6) Set “Level Value” to ~800. The image should now be black-and-white. 
7) Repeat Steps 4 and 5, but adjusting gain. 
8) Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK. 
Two sets of values are automatically saved with these controls—one value for Input 
#1, and one for Input #2 (analog). The current set of values depends on which source 
is in use. This enables a source to be processed correctly via 2 different inputs. 
 
Figure 3.26. Using “Odd Pixel Adjustment” 
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
eliminates “1 pixel on, 1 pixel off” patterns only, not any type of larger patterns.

Peak Detector 
The Peak Detector is fast method of defining individual input levels, and can improve 
the accuracy of input levels set by the Auto Input level function. Enabling the Peak 
Detector activates a special operating mode for detecting only pixels that are 
considered black or white—all other levels are displayed as a mid-level gray. When 
used with a 16-step grayscale pattern in which the two black and white bands are 
known to be at opposite edges of the image, you can watch these isolated areas while 
adjusting individual blacklevels and input drives until both bands are just visible.

Images from this source will then display correct blacks and whites without crushing 
or washing out. 
Level Detector 
The Level Detector checkbox enables a specific thresholds for blacks and whites—
input levels that fall below a specified Level Value (see below) are displayed as 
black, and all others are displayed as white. It aids in Odd Pixel Adjustment. To use: 
1.  Enable Level Detector and display a continuous grayscale. 
2. Set Level Value to near black (such as 200). 
3.  Adjust Offsets to minimize area of black stripe. 
4. Set Level Value to near white (such as 800). 
5.  Adjust Gains to minimize area of white stripe. 
Level Value 
The Level Value defines the value to be used by the Level Detector in recognizing 
blacks and whites. See Level Detector, above.

No function. 
The two “Option 
Card” entries In the 
Configuration 
menu identify 
which optional 
input modules 
(a.k.a. cards) are 
present at 
INPUT 5 
(Option 1) and 
INPUT 6 (Option 2). 
If either of these option slots are empty, the corresponding read-only menu entry does 
nothing. If there is a module installed, the corresponding menu entry may activate a 
submenu of further options pertaining to that module.  
For example, the Dual SD/HD-SDI module is factory-installed at 
INPUT 5 (Option 1). 
The Option 1 Card submenu provides controls for configuring the various 
connections on this multi-input, multi-output module. As desired for your 
application, you can define 1) which physical input loops through to which output, 
and 2) which functional input (main or PIP signal) loops through to which output. 
 
NOTE:  Seamless switching is not currently supported in this projector. 
PIP (Picture-in-Picture) and Seamless Switching are independent but related 
projector features that both utilize two image processing paths within the projector. In 
the case of Picture-in-Picture, this double processing enables you to display two 
different images simultaneously – typically a smaller “secondary” image within a 
large “primary” background.  In a seamless switch (not currently available for this 
projector), the double processing essentially occurs between displays so that a full 
image relayed from one source can smoothly transform into a full image from

another source. This change can be virtually instantaneous, or slowed as desired so 
that the current image appears to dissolve or “fade” into the new image. 
Options for enabling and controlling PIP and Seamless Switching all reside in the 
same menu. Note, however, that because both features utilize the projector’s double 
processing capability, PIP and Seamless Switching cannot be used together. For 
example, fading a pair of PIP images into a new display from a different source is not 
possible. 
For best PIP or Seamless Switching results, use two different signal types* as defined 
below. Do not mix two signals of the same type. 
Signal Type Description (Input Location) 
#1  5 BNCs (RGBHV or YPbPr) 
#2  DVI - I (analog or digital) 
#3  Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video 
signal via  Input 1 BNC connectors or via an analog option card). 
#4  Analog Option Cards 
#5  Digital Option Cards 
#6  Digital Option Cards 
* HD interlaced sources are not recommended for the PIP window. 
Other PIP or Seamless Switching tips to keep in mind include: 
• When using 2 digital signals or 1 analog and 1digital, each must be ≤ 165 
megapixels.  
• When using two analog signals, each must be ≤ 90 megapixels. 
• Avoid using an interlaced source in the PIP window 
• Seamless switching may affect image quality in some cases 
• Seamless switching is not currently supported in this projector 
 
NOTE: Controls for the primary image are all accessed through the Main menu. To 
control the secondary (PIP) image, access picture controls through the PIP and 
Switching menu. 
Use the first of six 
options in the PIP 
and Switching 
menu to enable and 
define how you 
want to use PIP. 
Options 8 and 9 
pertain to source 
switching only, and 
are not supported in 
this projector.

Four different sized lamps can be used with this projector: 2, 3, 4.5 or 6 kW. To 
ensure that the required ignition and power level is supplied to the lamp, you must 
define in software—preferably before power-up—which size lamp is installed, 
otherwise the lamp could be seriously overdriven or underdriven. Subsequent 
adjustments in the Lamp menu can then help to optimize lamp performance and 
ensure the brightest, most uniform image possible for the life of the lamp. 
The ideal time 
to check your 
lamp size is 
prior to each 
power up. This 
avoids the 
possibility of 
igniting your 
lamp with the 
wrong level of 
power: 
See Figure 3.29. 
Before 
powering up the 
projection head, 
press 
Menu. The 
LCD STATUS DISPLAY at the rear of the projector will show a “Lamp Size” of 2000, 
3000, 4500 or 6000 watts, depending on its most recent setting (factory 
default=6000). Select the lamp that is currently installed—if you are unsure, a 
qualified service technician must unlock the lamp door and look at the lamp.

NOTES: 1) Setting the 
lamp size requires a 
qualified technician. 
The required password 
for access is a service 
option that may be 
turned off. 2) Current 
lamp size should also 
be recorded on the 
“Lamp Installed” label 
located on the lamp 
door—see right. Mark 
the appropriate lamp 
size using a small blue 
dot label (see inside cover of this manual), or mark with a dry-erase pen. 
If the projector is already running, consult the Status menu to see which lamp size is 
currently recorded in projector memory. If this does not match the installed lamp, you 
can either change the Lamp Size setting in the service password-protected Service 
menu, which implements the new size at the next power-up, or you can power down 
and press 
Menu to use the LCD for lamp selection as described above (passwords are 
shown in Figure 3.29. Always indicate current lamp size on the Lamp Installed label. 
Note that any of the lamps can be powered by the 7kW ballast, but only the 2.0 kW 
and the 3.0 kW lamps can be powered by the 3 kW ballast (available in 2005). 
The high-voltage DC cables connected between the lamp ballast and the rear of the 
projection head can be 2-30 meters in length, depending on your site requirements 
and setup. The length currently in use must be defined in projector software for any 
new installation—this setting compensates for the voltage drop that occurs over 
distance and ensures that the proper voltage is maintained at the lamp. In the Lamp 
menu, set the “Cable Length (m)” slidebar to match that of your DC cables. By 
default from the manufacturer, this setting is 8 (approximately 25 feet). See Figure 
3.31.

LAMP ON:  
1.  With the projection head and ballast connected to each other, and with the 
ballast breaker on, press Menu. The LCD STATUS DISPLAY at the rear of the 
projector will show a “Lamp Size” of 2000, 3000, 4500 or 6000 watts, 
depending on its last setting. Factory default=6000. Use 
 or  to select 
the lamp that is currently installed. This should also appear on the Lamp 
Installed label located on the lamp door. NOTE: A lamp password is required 
to change lamp type/size, unless the “Enable Password” service option has 
been turned off. 
2.  Turn on the projection head and lamp by pressing 
 POWER on any of the 
projector’s keypads. 
3.  For subsequent power-ups of this lamp, press 
 POWER. There is no need 
to reset the lamp size until a different-sized lamp is installed. 
LAMP OFF:  
1. Press  (POWER) on any of the projector’s keypads. 
2. 
WAIT for fans to continue running for 10 minutes to cool the lamp. 
3.  Proceed with full shutdown of the system, if desired. 
If the lamp fails to ignite, the projector will automatically re-try ignition using 100% 
of the maximum power acceptable for the lamp. If this re-try also fails, and there is 
no error code indicating a specific problem such as an open lamp door or an over-
temperature condition, the lamp size may be incorrectly defined. For instance, the 
defined “Lamp Size” may be 2 kW when a 6 kW lamp is present. To check the 
“Lamp Size” setting, press 
Menu while the lamp is off. The LCD STATUS DISPLAY at 
the rear of the projector will show a “Lamp Size” of 2000, 3000, 4500 or 6000 watts, 
depending on its most recent setting (factory default=6000). Enter password (unless it 
has been turned off) and select the lamp that is currently installed. If the lamp still 
will not ignite, a qualified service technician should check all lamp connections and, 
if OK, replace the lamp. 
See also Section 5, Troubleshooting section. 
Whenever you install a new lamp in the 
projector, access the Lamp menu to record 
the lamp serial number in the projector’s 
memory. You can also choose a lamp mode 
for regulating power and light output, 
optimize lamp performance, and access 
other read-only information pertaining to 
past and present lamps. 
LAMP HOURS  shows the number of hours 
logged on the current lamp. Whenever you 
record a new lamp serial number, this value 
automatically resets to “0”, where it begins 
to log time for the new lamp. NOTE: Read-
only. This information also appears in the Status menu. 
LAMP S/N  is the serial number recorded for the current lamp. When you install a new 
lamp and enter its serial number, the number will appear here. NOTE: Read-only.   Turnin

Enter a checkmark for LAMP MESSAGE to enable a warning message that will appear 
upon power-up when the lamp has reached the specified lamp limit and should be 
replaced. Delete the checkmark to prevent display of this message—instead, when 
your lamp expires, only the status display messages on the back of the projector will 
provide the visual warning to replace the lamp. 
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) 
When a lamp warning message appears, press 
 to temporarily cancel the 
message. The message will continued to appear upon power-up until you install a 
new lamp. 
Set 
LAMP LIMIT to the number of hours you expect to log on the current lamp before 
replacing it. This will trigger a lamp message on-screen (if enabled). Recommended 
limits for each of the four lamp sizes are listed in Table 3.5 later in this section. 
NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally 
expected may no longer be possible. 2) Turning the lamp on and off reduces lamp life 
significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed 
the warranted lamp life, otherwise a lamp could become dangerously fragile with 
overuse. 
Set which 
LAMP MODE you want to use in order to control 
the light output. You can choose to run the lamp as bright as 
possible (i.e., always using maximum power—this is the 
default upon power up), or you can power the lamp with a 
specific wattage appropriate for the installed lamp, or you 
can set a specific intensity (brightness) to maintain. Although there are exceptions, 
generally higher light output or higher power settings can shorten lamp life. 
Use the lamp mode that best suits your brightness needs. For example, in a tiled 
application you may want to precisely match brightness levels between adjacent 
images—judge by eye and set each individual 
Lamp Power setting as necessary. Or 
you may simply always want images to be as bright as possible—choose 
Max 
Brightness
. Always keep in mind that higher lamp power settings shorten lamp life. 
Lamp modes are described below: 
• 
Max Brightness: The lamp will always burn as brightly as possible, driven by 
110% of the power level rating for the installed lamp (see Section 6, 
Specifications). Keep in mind that the “maximum brightness” for any lamp 
gradually diminishes with age—images will become dimmer over time. Its 
current output level (note: not in lumens) appears in the “
Intensity” option. 
NOTE: “Max brightness” mode shortens lamp life. Avoid over-driving a lamp 
for extended periods. 
• 
Intensity: Brightness will remain close to a specified level for as long as 
possible. Once you select this option, enter a number representing the intensity 
level (brightness) you wish to maintain—the projector will automatically 
adjust power as needed to maintain this intensity as closely as possible. Note 
that the intensity value is a correlation only and does not represent an actual 
lumens level. See “
Intensity” below.
