Audio/Video 
Synchronization Issues Due to its extraordinarily high level of video processing performance, the Dimension Digital 
Controller may distribute video signals with a perceptible level of audio latency. In order to 
easily solve this issue, Runco recommends using the Dimension Digital Controller with a 
high-quality audio receiver that has the ability to effectively synchronize audio and video 
signals.
Most mainstream audio receiver/switchers have the ability to synchronize the audio and 
video to the Advanced Television Systems Committee (ATSC) prescribed tolerances. 
According to the ATSC, the sound program should never lead the video program by more 
than 15 milliseconds, and should never lag behind the video program by more than 45 
milliseconds.
In addition, many video displays and A/V receivers introduce additional latency that needs 
to be compensated for during the installation. 
Table 3-4 shows the amount of possible audio latency given different signal input timings. 
Other Considerations Other considerations and tips that 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 that radiate electromagnetic energy such as 
motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers and elevators.

Installing the Optional 
CineWide Lens MountIf you are installing a standard X-400d/X-450d (without an anamorphic lens), skip this step 
and proceed with Mounting the X-400d/X-450d (page 32).
If you are installing an X-400d/X-450d/CineWide with a “McKinley” 
(cylindrical) anamorphic lens, proceed with Installing the Fixed 
CineWide Base Plate (Cylindrical Anamorphic Lens) (page 31). 
If you are installing an X-400d/X-450d/CineWide with a “Whitney” 
(prismatic) anamorphic lens, proceed with Installing the Fixed 
CineWide Base Plate (Prismatic Anamorphic Lens) (page 30). 
If you are installing a X-400d/X-450d/CineWide with AutoScope, proceed as follows to 
install the AutoScope lens motor.
1. Do not install the CineWide lens yet, only the fixed CineWide 
base plate or AutoScope lens motor. You will install the 
CineWide lens after you install the projector and adjust the 
primary lens. 
2. Some components shipped with your projector may differ slightly 
from what is shown in these instructions.

Install Ceiling Mount Adapters/Projector Stands: For ceiling installations, the 
adapters bring the attachment points for the projector mounting rails (included with the 
projector ceiling mount kit) from the bottom of the projector up above the AutoScope lens 
motor housing. For floor installations (where the projector is upright), the adapters allow 
the projector to lie flat on the mounting surface.
Using eight (8) each of the supplied, Pan-Head Phillips screws, attach the AutoScope 
Ceiling Mount Adapters/Projector Stands to the projector as shown in Figure 3-7.

Mounting the 
X-400d/X-450dThere are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. 
Floor Mounting (Upright)In typical front and rear screen installations, the projector can be mounted to a secure and 
level surface such as a table or cart. Carts are useful when moving a projector during a 
presentation or from site to site. If possible, lock the wheels when it’s in position to prevent 
it from being moved during a presentation.
Ceiling Mounting
(Inverted)For fixed installations, and for those that want the projector out of sight or have a limited 
space for projector and audience, you can invert the X-400d/X-450d and suspend it from 
the ceiling using a specially-designed ceiling mount fixture. 
For detailed installation instructions, refer to the documentation provided with the ceiling 
mount kit. 
Installing the Projector in
an EnclosureThe projector can also be inverted and placed in an enclosure above and behind the 
viewing area. Install four feet on the inside bottom surface of the enclosure on which the 
projector can rest. A variety of materials can be used for this purpose (for example, rubber 
crutch tips or turntable feet). 
Adjusting the Projection
AngleIf the X-400d/X-450d is ceiling-mounted and the screen is significantly lower than the 
projector, you can tilt the projector at a slight angle by adjusting the ceiling mount. 
The projector can be rotated (side-to-side) up to 360 degrees and mounted without it 
affecting performance. However, to ensure optimal performance of the lamp, limit the 
front-to-back tilt of the projector to ±20 degrees; see Figure 3-11. 
Figure 3-11. Mounting Angle Ranges (Front-to-Back and Side-to-Side)
If you do this, you may need to shift the image using the on-screen display (OSD) controls, 
to compensate. For detailed instructions, refer to Primary Lens Adjustments: Focus, 
Zoom and Position on page 49.

Mounting the 
Dimension Digital 
ControllerThe Dimension Digital Controller unit can be placed on any flat, stable surface such as a 
shelf or table, or it can be rack-mounted using the supplied mounting hardware. Place it in 
a location that provides easy access to the power connectors. 
The Dimension Digital Controller unit requires 2U (3.5 inches) or more of vertical rack 
space. 
To mount the Dimension Digital Controller in a standard, 19-inch equipment rack, install 
the mounting ears on either side of the chassis using the supplied screws; see Figure 
3-12. Then, secure the mounting ears to the rack.

System 
InterconnectionsProceed as follows to connect the X-400d/X-450d system components to each other and 
to AC power.
When connecting your equipment:
 Turn off all equipment before making any connections.
 Use the correct signal cables for each source. 
 For best performance and to minimize cable clutter, use high-quality cables that are 
only as long as necessary to connect two devices. (Don’t use a 20-foot cable when a 
6-foot cable will suffice.) 
 Route all cables through the opening at the bottom of the projector. 
 Ensure that the cables are securely connected. Tighten the thumbscrews on 
connectors that have them.
Connector Panel AccessTo access the connector panel, pull firmly 
on the cable access cover to open it.
Connecting the Dimension
Digital Controller to the
ProjectorDigital Video Connection: Connect the HDMI Out To Pri. Display connector on the 
Dimension Digital Controller to the PRIMARY input on the projector. Similarly connect the 
HDMI Out To Sec. Display connector on the Dimension Digital Controller to 
SECONDARY input on the projector. 
RS-232 Connection: Connect the Pri. Display Control output from the Dimension 
Digital Controller to the RS232 input on the projector. 
Use a standard, modular telephone cable with RJ11 plugs at both ends. On the projector 
end, use the provided RJ11-to-DB9 adapter. This adapter is wired as shown in Figure 
3-13.
