2-5 INSTALLATION AND SETUP Figure 2.2. Poor Screen Placement Ideal Room Lighting The high brightness output of this projector is certainly well suited for locations where ambient lighting is less than optimum for projection, yet there are still many simple things you can do to optimize your installation. Visiting a movie theater can give you an idea of what makes an ideal projection environment. Walls, floors and furnishings are dark and have a matte finish. A projection room should not have white...

2-6 INSTALLATION AND SETUP Even with all lighting removed it is still possible that room reflections within the room can slight- ly degrade the image. Light from the projection screen should be absorbed by the ceilings, walls and floors so that it will not be reflected back to the screen. Again, keep reflective surfaces to a minimum. Other Considerations Here are some other considerations and tips which can help you improve your installation: zVentilation is an important factor when preparing a...

2-7 INSTALLATION AND SETUP Figure 2.4. Screen Locations for Maximum Audience Coverage 2.3 Projector Position and Mounting 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...

2-8 INSTALLATION AND SETUP Vertical & Horizontal Position THE VERTICAL POSITIONof 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. In addition, vertical position of the image can be manually offset-that is, moved up or down-by turning the top screw on the front of...

2-9 INSTALLATION AND SETUP Figure 2.7. Maximum Vertical Offsets (ZOOM LENSES) NOTES: 1)If you cannot raise or lower the image enough using mechanical vertical offsets, try adjusting V-Positionin the Size and Positionmenu (see 3.6, Adjusting the Image). 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 be exceeded, however this may affect image quality. 4)Simultaneous horizontal and...

2-10 INSTALLATION AND SETUP Mounting 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 over- turn. The table or cart should be reasonably level. Fine adjustments to the projec- tor level can be made by adjusting the height of the projector legs; refer to 2.7, Levelingfor details. Special Mounting Note that projector can be rotated...

2-11 INSTALLATION AND SETUP Folded Optics In rear screen applications where space behind the pro- jector is limited, a mirror may be used to fold the opti- cal path. The position of the projector and mirror must be accurately set-if considering this type of installation, call your Runco dealer for assistance. 2.4 Source Connections The rear panel of the projector provides standard input panels to which you may connect a vari- ety of sources. See Figure 2.10-the lower left area (INPUT 1) typically...

2-12 INSTALLATION AND SETUP RGB Signals INPUT 1provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec- tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders with an RGB output. This projector supports multiple sync types with RGB signals: sync-on- green, composite sync, and separate H & V syncs. NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec- tors at the projector end and a different type of...

2-13 INSTALLATION AND SETUP YPbPr Signal (COMPONENT VIDEO) Connect a YPbPr signal (component video) to INPUT 1as shown in Figure 2.12. Figure 2.12. Connecting YPbPr Signal NOTES: 1)If, for some reason, the projector fails recognize a YPbPr signal, specify this Color Spaceoption within the Image Settingsmenu. 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. AUDIO for INPUT 1:To control audio...

2-14 INSTALLATION AND SETUP Composite Video 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 orthe RCA phono jack at -do not use both as inputs. See Figure 2.13. AUDIO for INPUT 3:To control audio levels in an audio/visual system, connect pre-amplified (line level) audio inputs to the “IN 3”left and right channel audio inputs located near the...
