Figure 3-4. Horizontal Lens Shift (EXAMPLE ONLY)
Vertical Lens Shift: The LS-12HBd zoom lenses (Proteus 2 through 6) provide up to 
65% of vertical lens shift in either direction (up or down). For example, with a 96 x 54-inch 
(16:9) screen, you can shift the image up to 35.10 inches (0.89 meters) below the screen 
center. (Vertical lens shift is not possible with the Proteus 1 lens.)
Horizontal Lens Shift: The LS-12HBd zoom lenses (Proteus 2 through 6) allow up to 
30% of horizontal lens shift in either direction (left or right). For example, with a 
96 x 54-inch (16:9) screen, you can shift the image up to 28.80 inches (73.15 cm) left or 
right of the screen center. (Horizontal lens shift is not possible with the Proteus 1 lens.)

Folded OpticsIn rear-screen applications where space behind the projector is limited, a mirror may be 
used to fold the optical path, as shown in Figure 3-5. The position of the projector and 
mirror must be accurately set. If you are considering this type of installation, contact your 
dealer for assistance.
Figure 3-5. Folded Optics➤
For best performance, always use “first-surface” mirrors in your 
rear-projection installation (as opposed to conventional, 
“second-surface” mirrors with the reflective surface behind a 
transparent substrate such as glass or acrylic). 
First-surface mirrors provide a strict reflection without the 
“ghosting” effect seen with a second surface mirror, where a faint 
secondary reflection could be observed coming from the front 
surface of the glass. 
This is especially critical for 3D viewing; with a conventional 
second-surface mirror, the resulting image quality may be 
unacceptable.

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.

Mounting the 
LS-12HBdThere 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 LS-12HBd and suspend it from the 
ceiling using a specially-designed ceiling mount fixture. 
Install the ceiling mount kit according to the instructions provided with it. 
If you are ceiling-mounting an LS-12HBd with an anamorphic lens, perform these 
additional steps to secure the plate Security Hooks to the ceiling (refer to Attaching the 
Security Hooks on the previous page). 
1. Install ceiling hooks (not supplied) into the ceiling directly above the Plate Hooks. The 
ceiling hooks should be small enough to accept a Chain End but strong enough when 
installed to each support 40 pounds or more.
2. Attach a Chain End to the Chain and then connect it to one of the ceiling hooks. 
3. Cut the Chain to a length equal to or slightly greater than the distance between the 
ceiling hook and the corresponding Plate Hook.
4. Attach a Chain End to the other end of the Chain. Then, use the Chain to connect the 
ceiling hook and the Plate Hook.
5. Repeat Steps 2 through 4 for the other ceilling hook/Plate Hook pair.
Installing the Projector in 
an Enclosure The 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). 
Use only the Runco-approved ceiling mount kit designed for your 
projector.

Adjusting the Projection
AngleIf the LS-12HBd 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 3-6.
Figure 3-6. 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 51.➤
