    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

    with any lens/projector combination. In addition, keep in mind that long throw
    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.
    Figure 2.15. Average Maximum Horizontal Offsets in X10 and S12(SEE SECTION 5 FOR SPECIFIC HORIZONTAL OFFSETS FOR EACH LENS)
    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

    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.
    Figure 2.17. Front Connector Panel
    NOTE: For all connections as described in the following pages, use high-quality
    shielded cables only.

    Connections 
    						
    							INSTALLATION & SETUP
    Roadie S12/X10 User’s Manual2-15
    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.

    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.
