• Power: The power supplied to the lamp will remain at your specified wattage 
level. Once you select this option, enter the number of watts representing the 
power level you wish to maintain. See “
Power” below. 
POWER - This slidebar and number indicates how 
many watts are applied to the lamp. You can apply 
anywhere from 75% of the maximum power intended for the installed lamp up to an 
“over-drive” that exceeds the maximum rating by approximately 10%. Set for the 
number of watts as desired, keeping in mind that lower power levels produce dimmer 
images. When in either “
Power” or Max Brightness modes, the power level remains 
constant. Specifying a maximum power level here is the same as operating in 
Max 
Brightness
 mode, and will shorten lamp life.  
NOTES: Power level can be set only if the lamp is in “power” mode. 
INTENSITY – This value and slidebar represents the 
current brightness of your lamp, decreasing over time 
when you are operating in 
Max Brightness mode or at a specific Power level. 
However, when you are operating in “
Intensity” mode, this value remains at the 
original “
Intensity” setting chosen, and cannot be adjusted.  
NOTE: The number shown for “intensity” is not the actual lumen output, but rather a 
correlated value only—9415 may represent 20,000 lumens, for example. 
To use “
Intensity” mode, judge by eye and set the level as desired for your 
application, remembering that higher settings can significantly shorten lamp life. 
Over time, the projector will automatically increase the power supplied to the lamp as 
needed to maintain the chosen intensity as closely as possible. This mode is known as 
“Brightness Tracking” or “LiteLoc”. 
Since power increases over time in this mode, prevent prolonged over-driving by 
checking the lamp power readings periodically. 
HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your “Intensity” 
setting until the required power exceeds the maximum rating for the lamp (2.0, 3.0, 
4.5,  or 6.0 kW) by approximately 10%. The lower the setting, the longer it will take 
to reach this threshold, and the longer you can maintain the desired brightness. Keep 
in mind that once the lamp power reaches its maximum wattage (see “
Power”, above), 
this tracking is no longer possible. At this point, the lamp will gradually begin to dim 
as usual, even though your original “
Intensity” value will still appear in the menu. To 
resume accurate tracking, reduce the intensity setting so that the resulting “
Power” 
value is less than its maximum—the lower the intensity, the longer it can be 
maintained. 
For example, a 6000 watt lamp (6.0 kW) can be safely driven at no more than 6600 
watts. To produce desired brightness at the screen, a new lamp would likely need less 
than this maximum rating—perhaps 5120 watts (example only). Over time, however, 
the lamp will require more and more current in order to generate the desired light, 
until eventually the lamp wattage reaches its 6600 “overdrive” maximum, and the 
lamp power automatically levels off. At this point, the tracking function terminates 
(i.e., the power level stabilizes) and the lamp will begin to dim normally. Either 
reduce your “
Intensity” setting or replace the lamp.

3-56 
Roadie 25K User’s Manual  
Do not lower the “Intensity” so much that the corresponding “Power” value reaches 
its minimum—the intensity setting will be inaccurate and cannot be maintained. For 
best results in achieving uniform intensity amongst tiled images, choose an 
“
Intensity” setting that enables all lamps to operate at less than the maximum number 
of watts available in your projector but high enough to keep the corresponding lamp 
power above its minimum. See “
Power”, above. 
NOTES: 1) Lamps become more stable over time, thus a specific intensity is more 
easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in 
Intensity mode 3) Intensity cannot exceed the output of Max Brightness mode. 
LAMP HISTORY - This read-only option lists the most lamps most 
recently installed and recorded in the projector. Lamp History 
automatically updates whenever you record a new lamp serial 
number—the new lamp is added to the bottom of the list. 
Use 
CHANGE LAMP to record the serial number for a newly installed lamp: 
In the Lamp S/N window, use the number text entry keys to record the new lamp 
serial number, and press 
 again to accept the change. See Using Slidebars and 
Other Controls if you need help entering the number. Once entered, the new lamp 
serial number will be added to the Lamp History menu and the Lamp Hours timer 
will reset to “0”. Lamp Mode and Lamp Limit remain as they were for the previous 
lamp, and can be changed at any time. 
 
Figure 3.33. Recording the New Lamp Serial Number 
NOTE: Enter a serial number only if you have just installed a new lamp. This will 
help ensure that lamp timer is not reset on an old lamp and that the number of hours 
logged on the lamp will be accurate. 
 IMPORTANT  
Always DO record the serial number of a NEW lamp. 
CABLE LENGTH (m) - Use this slidebar to define what lengths of high voltage DC 
cables are currently connected between the lamp ballast and the “Anode” and 
“Cathode” ports on the rear of the projection head (refer back to Figure 3.31). This 
regulates the voltage drop that occurs over distance, and ensures that adequate 
voltage reaches the lamp. Particularly in projectors rented for temporary installations, 
this setting may have to be changed from its last use. Adjustment range is 2-30m 
(6½-100 ft.).

 IMPORTANT  
Always match this setting to your current cable lengths. 
Use LampLOC to align a newly-installed lamp after its first power-up. For best results, 
select the 
DO AUTO control in the LampLOC menu and wait a few moments for the 
X-Y-Z values to stabilize. The motors and sensors will work together to precisely 
position the lamp for optimized performance and brightness at the screen, utilizing 
filtering to eliminate signs of lamp flicker. Progress status is displayed near the 
bottom of the menu. When complete, the lamp alignment is optimized for the current 
installation. 
NOTES: 1) A 10-minute warm-up is recommended before adjusting LampLOC. 2) 
Intensity mode(brightness tracking/LiteLOC) is disabled during a LampLOC 
adjustment.

4.5 112-135  3-Phase 
6.0 126-155  
NOTE: Using “Max Brightness” or a maximum Lamp Power setting will exceed the 
maximum values shown here by approximately 10%. Avoid prolonged use. 
Using the LampLOC Slidebars 
The individual 
LampLOC
 slidebars, 
each of which moves the 
lamp along one axis only, 
are provided as a 
reassuring back-up should 
the 
DO AUTO button fail or 
if you feel a manual, 
operator-assisted lamp 
optimization will produce 
more output. Either 
measure your results with 
a light meter at the lens and screen, or simply watch the intensity values near the top 
of the menu. Note that with these slidebars you may attain a slightly higher peak than 
with the 
DO AUTO button, but this peak may not be centered on the lamp curve thus 
lamp performance may not be optimized (whereas the 
DO AUTO button also utilizes 
filtering to eliminate the effects of any lamp flicker). In general, use the individual 
slidebars if you feel it is unavoidable. 
HOW TO ADJUST (IF USING A LIGHT METER): First obtain peak readings on a light 
meter centered in front of the lens, then at the center of the screen. For each button, 
adjust in one direction, then back up when the reading begins decreasing. 
NOTES: 1) Display a 100% white internal test pattern. 2) Use a tripod to center the 
light meter with the lens. Distance from the lens does not matter. You may need an 
attenuator, or wish to construct an internal foil aperture first. 3) This is an optional 
procedure—watch the intensity feedback shown near the top of the menu if preferred.

4.  Repeat Steps 1-3 as necessary. 
5.  Repeat Steps 1-4, but reading at the screen instead of at the lens. 
6.  Reset Lamp Power or Intensity if desired. 
Close the internal electro-mechanical shutter (
Shutter) to blank the image and put the 
projector in a cooler stand-by mode with minimum power going to the lamp. Lamp 
power will be reduced to 60% of the maximum rating for 4.5 and 6.0 kW lamps, or 
75% of the maximum rating for 2.0 and 3.0 kW lamps. Upon opening the shutter and 
restoring the image, the lamp power will return to its previous setting.
 
When a new lamp is installed and its serial 
number recorded by selecting “Change 
Lamp” in the Lamp menu, the lamp timer 
resets to “0” and begins logging time for 
the new lamp. This tally appears in both 
the Lamp menu (see right) and the Status 
menu. 
To review the number of hours logged for 
previous lamps, consult the Lamp History 
menu. 
If the Lamp Message checkbox has been 
enabled in the Lamp menu 
(recommended), an expiry message will appear upon power-up when the lamp has 
reached its defined Lamp Limit. The lamp should be replaced. 
The Lamp Limit setting should never exceed the warrantied lamp lifetime by more 
than 20%, as an old lamp becomes increasingly fragile and more prone to sudden 
failure or even explosion, which can be damaging as well as dangerous. These 
maximum limits depend on the lamp size—see Table 3.5.

Lamp (kW) Replace BEFORE: 
2.0 2880 hours 
3.0 1728 hours 
4.5 1080 hours

NOTE: Hours shown here are 20% beyond the 
pro-rated credit warrantied lifetimes (see Section 6, Specifications). Do not exceed.

When an installation requires multiple projectors, you can use the RS232 and/or 
RS422 serial ports to daisy-chain the units together and control the group with a 
single keypad or a computer/controller connected to the first projector. In such a 
network, you can choose to broadcast commands to the entire group, or use the 
Proj 
key as desired to limit responses to an individual projector. Or you may prefer that 
each projector in an installation stands alone and responds only to a unique 
transmission protocol from its own keypad (NOTE: alternative IR keypad protocols 
are not supported in v1.1 software.) 
Alternatively, you may want to add projectors to an Ethernet network. 
NOTE: Refer back to 3.8, Adjusting System Parameters and Advanced Controls for 
complete information about communicating with multiple projectors. 
In a multiple-projector wall, you will likely want to precisely match color and intensity 
from image-to-image so that the full wall is as uniform as possible. This matching is 
typically done in conjunction with brightness uniformity and edge blending. 
Preliminary Calibration 
As a final part of the manufacturing process, all primary colors in the projector are 
precisely set to pre-established values to ensure that overall color performance is 
optimized and is as accurate as possible (refer back to Figure 3.23). Upon installation 
at a site, however, lighting and other environmental factors may slightly change how 
these colors appear on your screen. While the change is negligible in most cases, you 
may prefer to recover the originally intended color performance before trying to 
match colors from several projectors. Or you may be renting a projector in which the 
colors were changed for use at its previous site, but are not ideal for yours. 
The good first step in achieving such consistency is to use a color meter to measure 
the native primary colors—red, green, blue, and white—as they appear at the screen 
and record these as Color Primary Settings in the Service menu (password-protected) 
for each projector. On the basis of these new values, which are stored in memory, 
each projector will then automatically calculate any necessary corrections to 
reproduce the original factory colors under the current environmental conditions. 
This essentially calibrates a projector to its surroundings, compensating for factors 
such as screen type, lamp and/or ambient lighting that can alter the final color 
characteristics on-screen, and will improve color accuracy and consistency in a group 
of projectors. It ensures a good starting point for further customizing and matching. 
To return to the factory-set color primaries, such as when a projector is moved to 
different site, you must access the Service menu (password-protected). Select the 
Reset to Factory Defaults? option in the Color Primaries submenu. Then repeat the 
calibration process describe above, if desired, and continue with matching of colors. 
NOTE: Using the Service menu to set the projector’s primary colors as described 
above is not a requirement for color matching, and is rarely necessary.

Color Adjustment Procedure 
Once the Color Primary Settings are calibrated for the site (see above), use the Color 
Adjustments by X,Y menu to further refine each projector’s fundamental primary 
colors so that the hue and intensity of each color appears the same from one display 
to another. Once matched, you will have created a single new shared range of colors 
or “color gamut” that all projectors can produce. This palette—named User 1, 2, 3 or 
4—can be applied or disabled for a source at any time throughout a bank of adjacent 
displays, simplifying both the setup and maintenance of a “seamless” wall. 
1.  Set up and optimize all projector settings. You can ignore color temperature, since 
you will be defining a new color palette, but do set up each projector in every 
other aspect. Closely align all screen edges. 
2.  Assign projector numbers to make communications easier. Use a wired keypad. 
3.  Use the same lamp mode for all projectors, and do the following:

You may prefer to use 
the Color Saturation 
menu to match colors 
across multiple screens. 
In the three Color 
Adjustment submenus 
(Red, Green, Blue—see 
right), set all main 
values to “100” and the 
secondary values to “0”. 
Then judge by eye and 
adjust the slidebars as 
needed. Note that 
adjustments here define 
new x/y coordinates in 
the Color Adjustments 
by X,Y menu. 
For best results, the 
Color Adjustments by 
X,Y menu should be 
used first. 
WHAT IS BRIGHTNESS UNIFORMITY? When used to refine screens already matched 
for their primary colors (see Matching Colors in Multiple Screens, above) and overall 
light output, proper adjustment of Brightness Uniformity can create an exceptionally 
smooth screen in which: 
• no area of the screen appears more red, green or blue than another 
• no area of the screen appears brighter than another color and light output 
from one screen closely matches adjacent screens 
• color and light output from one screen closely matches adjacent screens 
Although the Brightness Uniformity control can be used for a stand-alone projector, it 
is particularly useful for setting up and maintaining tiled images that form a cohesive 
display wall in which the color “cast” and light output appear uniform throughout 
each image as well as throughout the entire wall. The procedure provided here 
assumes a multiple-screen application. 
 Before You Begin 
Read through the entire procedure before attempting to adjust Brightness Uniformity 
controls, and keep in mind the following checklist of prerequisites and guidelines:

lamps, either set up Brightness Uniformity after this period, or do an initial 
setup and re-check at 100 hours.

Roadie 25K User’s Manual  
• If you have created a “User 1” color gamut (recommended) for a well-
matched wall, select “User 1” and continue to Step 
1e. 
• If you prefer maximum brightness rather than a particular color temperature, 
select “Max Drives”. 
 IMPORTANT  
Do not change User 1 Color Adjustment 
in color-matched applications! 
1e) In the White Uniformity 
menu, set the “Overall” 
output level to 50.0 and all 
remaining slidebars to 0.0. 
This decreases the light 
output just enough 
throughout the screen so that 
any color level can then be 
increased later as necessary 
for matching light output 
from zone-to-zone. Do not 
exceed 50.0 for “Overall”—a higher level will likely interfere with achieving 
brightness uniformity and is not recommended. 
Ensure that overall light output remains well-matched from one screen center 
to the next. Where necessary, increase or decrease Lamp Power slightly to 
recover center matches. 
Step 2: Adjust Color (level of red/green/blue) in 8 Zones 
NOTES: 1) At this point, ignore menu colors and the brightness of individual zones. 
2a) On each screen, compare the color temperatures in the 8 target zones (4 edges 
and 4 corners) to that of the color temperature of the center. Compare using a 
white field only, and take note of any areas that do not match the center. Also 
decide if any screen exhibits a more obvious color shift than other screens—
begin with this screen in Step 
2b.  
2b) Return to the Brightness Uniformity menu. Beginning with the screen that exhibits 
the most obvious color shift(s), for each edge that exhibits a noticeably different 
color temperature from the center, select the corresponding Uniformity adjustment 
menu—Left, Right, Top or Bottom. For example, if any part of the left side is too 
blue, too red or too green, adjust the colors in the Left Uniformity menu (i.e., 
change their light output) until all portions of the left side closely match the center 
color temperature. Adjust an edge first (focusing on its center), then adjust its 
corners. See Figure 3.38.
