Other considerations and tips which can help you improve your installation:
• Ventilation is an important factor when preparing a projection room. The ambient
temperature should be kept constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature can
cause drifts in the projector circuitry which may affect performance.
• Keep the projector away from devices which radiate electromagnetic energy such
as motors and transformers. Common sources of these are slide projectors,
speakers, power amplifiers, elevators, etc.
• For rear screen applications, less space is required if a mirror is used to fold the
optical path.
• Choose the right screen size for the application:
◊ As screen size increases, magnification increases and reduces brightness.
Select a screen size which is appropriate for the venue, but not larger
than that required.
◊ Installing a large screen in a small room is similar to watching television
close up; too large a screen can overpower a room. A good rule of thumb
is to be no closer than 1.5 times the width of the screen.
◊ Larger screens require greater attention to lighting conditions.
• When laying out the projection room, consider positioning the projector and
screen in a manner which will achieve maximum audience coverage and space
efficiency. For example, placing the screen along the larger wall in a rectangular
room will reduce audience coverage. Figure 2.11 shows two examples of how
audience coverage is maximized.

Installation type, screen type, and lighting all affect where the projector is positioned.
In addition, both throw distance (the distance between the projector and screen) and
vertical position (the height of the projector in relation to the screen) must be
determined for every new installation. Both depend on the screen size and lens type
you are using. Make sure that the room can accommodate the required position of the
projector for the chosen screen size.
Throw distance is the distance between the projectors front feet axes and the screen.
For any installation, an accurate throw distance must be determined in order for the
image to be of the right size for your screen–the farther the projector is from the
screen, the larger the image.
NOTE: If your projector is tilted in relation to the screen, as is sometimes the case
for large venues or elevated installations, throw distance still represents the smallest
measurement between the screen and front feet.
Throw distance is roughly equal
to the horizontal width of the
screen multiplied by the type of
lens you are using. For example,
if you are using a 0.8:1 lens (0.6:1
as SXGA), proper throw distance
will be approximately 0.8 (0.6 as
SXGA) 
x the screen width. Once
you know your screen size and
lens, you can estimate throw
distance needed—see example at
right.
IMPORTANT: For proper
placement in an installation, always refer to the throw distance formula and/or
graph for your lens as listed in Appendix E. Keep in mind that due to lens
manufacturing tolerances for lens focal length, actual throw distance can vary
±5% or more between lenses described as having the same throw ratio.
THE VERTICAL POSITION of the projector in relation to the screen also depends on the
size of the screen and the lens type. Correct vertical position helps ensure that the
image will be rectangular in shape rather than keystoned (having non-parallel sides)
and that image focus and brightness both remain optimized.
NOTE: A keystoned image can be corrected through software in the X10. See Section
3.
In addition, vertical position of the image can be manually offset—that is, moved up
or done. Press 
Lens to display the Lens Control menu, then adjust offsets with 
and . Note that the range of adjustment depends on the type of projector as well
as lens and whether or not you are also offsetting horizontally. See Table 2.1 for the
percentage of the image that can be displayed above and below the center of each
type of lens compatible with your projector. See Figure 2.13 for average X10 offsets
(non-VistaPro lenses only). All S12 offset ranges are illustrated in Figure 2.14.
NOTE: Due to manufacturing tolerances, any offset range can vary ±5% or more
between lenses described as having the same throw ratio, between projectors, and

distances significantly reduce offset ranges.

NOTES: 1) For any projector, if you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Position in the Size and Position menu
(see 3.6, Adjusting the Image) when displaying at less than the maximum size. 2) If
the image becomes keystoned or exhibits uneven brightness, the projector may simply
be too high or low in relation to the screen. 3) Recommended offset ranges can

sometimes be exceeded, however this may affect image quality. 4) Simultaneous
horizontal and vertical offset can limit the adjustment range of each.
THE HORIZONTAL POSITION of the image can be offset—that is, shifted left or right
of lens center—by using the 
Lens key. This displays the Lens Control menu, where
offsets can be adjusted with 
 and . Maximum horizontal offsets—expressed
as the maximum percentage of the image that can be projected to either side of the
lens center—are shown in Figure 2.15. While offsets vary with lens type (see Section
5, Specifications), typical offsets are approximately 77% in X10, 67% in S12.

For typical front or rear floor mounts, mount the projector on a
secure table or cart. Take care with a mobile cart—avoid sudden
stops, excessive force and uneven surfaces that may cause the
projector and cart combination to overturn.
The table or cart should be reasonably level. Fine adjustments to the projector level
can be made by adjusting the height of the projector legs; refer to 2.7, Leveling for
details.
Special Mounting
Note that projector can be rotated and mounted at any vertical angle—i.e., you can
tilt the face of the projector up or down as much as desired for your installation. The
side-to-side tilt, however, must not exceed 15° (see Figure 2.16). This limit ensures
that the arc lamp in the projector operates properly and safely. Always make sure that
exhaust air from the projector does not vent towards the lens, otherwise you may
detect heat waves in your projected image.Mounting

You must use the proper ceiling mount fixture or stacking kit for your projector. For
more information, contact your dealer.
In rear screen applications where space behind
the projector is limited, a mirror may be used to
fold the optical path (see right). The position of
the projector and mirror must be accurately set—
if considering this type of installation, call your
dealer for assistance. Folded O

The front panel of the projector provides standard input panels to which you may
connect a variety of sources. See Figure 2.17–the lower left area (
INPUT 1) typically
accepts an RGB signal from an external RGB source, or it can also be used for YPbPr
signals or additional video sources. The upper right panel–the Video Decoder
Module–accepts only composite video at 
INPUT 3 or S-video at INPUT 4 from devices
such as VCRs, laser disk players or DVD players. There are also several optional
interfaces available for connecting other sources at 
INPUT 2. Such an option installs in
the upper left area, just below the projector front ID label.

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical
connection would be to an RGB source such as VGA, SVGA, XGA, Mac,
PowerMac, DEC, Sun, SGI and others. This projector supports multiple sync types
with RGB signals: sync-on-green, composite sync, and separate H & V syncs.
NOTE: Depending on the source, you may need a custom adapter cable with BNC
connectors at the projector end and a different type of connector at the other (such as
a 15-pin D connector for computer sources). Contact your dealer.
Connect the 
SYNC BNC input(s) first. Then connect the red, green and blue source
outputs to the 
RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses
sync-on-green, only the red, green, and blue connections are required. If the source
provides a composite sync output, connect it to the 
SYNC input labeled HOR/COMP. If
the source provides separate horizontal and vertical sync outputs, connect horizontal
sync to the 
SYNC input labeled HOR/COMP and connect vertical sync to SYNC input
labeled 
VERT. See Figure 2.18.
NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB
signal, specify this Color Space option within the Image Settings menu. See 3.6,
Adjusting the Image. 2) To connect YPbPr signals–such as from DVD or analog HDTV
sources–to 
INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals on
the next page.

Connect a YPbPr signal (component video) to INPUT 1 as shown in Figure 2.19.
Figure 2.19. Connecting YPbPr Signal
NOTES: 1) If, for some reason, the projector fails to recognize a YPbPr signal,
specify this Color Space option within the Image Settings menu. See 3.6, Adjusting
the Image. 2) Do not connect digital component signals (known as YCbCr) to 
INPUT
1
. Use the appropriate digital interface installed at INPUT 2.
The video decoder input panel provides simultaneous connection of both a composite
video source (
INPUT 3) and an S-Video source (INPUT 4).
If connecting a composite video source, use the Composite BNC connector or the
RCA phono jack at 
INPUT 3–do not use both as inputs. See Figure 2.20.
NOTE: If you want to loop a composite signal through to another projector or
display device, see Video Loop Through later in this section.

The video decoder input panel provides simultaneous connection of both a composite
video source (
INPUT 3) and an S-Video source (INPUT 4).
If connecting an S-Video source, use the 4-pin mini DIN connector or the Y and C
BNC connectors (luma and chroma) at 
INPUT 4–do not use both as inputs. See Figure
2.21.
