Runco's revolutionary QuantumColor" projectors pair energy-saving LED technology with proprietary Runco engineering to create unsurpassed performance and unrivaled customization.<br><br> The Runco QuantumColor Q-750i maximizes the benefits of Runco's new InfiniLight" lampless LED illumination technology to provide an infinite light source that creates an energy-efficient projector with the widest color gamut ever available in home theater projection. But simply creating a projector platform with lampless technology and the largest color gamut isn't enough. Harnessing its incredible color options, Runco introduces its revolutionary new Personal Color Equalizer", which allows color adjustment that includes those exactly defined by the cinematographer and the color preferences of each individual viewer for each source.<br><br> Proprietary Runco Smart Color (RSC") provides a hue compensation curve and gamut mapping that allows for lifelike, accurate flesh tones while increasing color saturation, without sacrificing the purity of other colors. In addition to Runco's proprietary InfiniLight, Personal Color Equalizer and Runco Smart Color, Runco the Q-750i can also be paired with Runco 9s award-winning CineWide" and CineWide with AutoScope" technology. CineWide provides uncompromised widescreen reproduction of movies originally filmed in the CinemaScope" 2:35:1 format.<br><br> It maintains constant vertical height on the screen just as in a movie theater. When a viewer transitions from 1.78:1 (16:9) program material to superwide 2.35:1, the image simply gets wider while full screen height is maintained, eliminating useless black bars on the top and bottom of the screen. Runco CineWide is achieved through Runco's ingenious combination of software, electronics and precision anamorphic optics.<br><br> With Runco CineWide, the projection system is able to use the full pixel array, thereby producing a 2.35:1 image with enhanced resolution and increased brightness. No resolution or image area is lost to those black bars that contain no picture information. CineWide with AutoScope provides a motorized, remote-controlled anamorphic lens mechanism.<br><br> Discrete IR and RS-232 control make custom installation seamless, while discrete source and aspect ratio selection accommodate any automation control system. CineWide requires the use of a 2.35:1 or similar aspect ratio superwide format screen.

Whether you are installing a projector temporarily or permanently, you should take the following into account to ensure your projector performs optimally.<br><br> Installation Type Choose the installation type that best suits your needs: front or rear screen, floor mount or inverted mount. Table 3-2 compares these various installation methods. Ambient Light In general, minimize or eliminate light sources directed at the screen.<br><br> Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant.

This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be the right size for your screen. You can quickly estimate the throw distance by taking the width of the screen and multiplying it by the lens throw ratio; see Figure 3-1.<br><br> The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. Figure 3-1. Estimating Throw Distance Table 3-3 gives the throw ratios for the Q750i Series.<br><br> ¤ Table 3-3.

Ideally, the projector should be positioned perpendicular to the screen and in such a way that the lens center is aligned with either the top or bottom edge of the screen area, and centered horizontally.<br><br> See Figure 3-2.

Lens shift is generally expressed as a percentage of the screen height or width, as shown in Figure 3-3 and Figure 3-4. Figure 3-3.<br><br> Vertical Lens Shift (Example Only) Vertical Lens Shift (Standard Q-750i): The Q-750i provides up to 60% of vertical lens shift up or down. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image up to 33.60 inches (0.85 meters) above or below the screen center. Vertical Lens Shift (Q-750i/CineWide or Q-750i/CineWide with AutoScope): The Q-750i provides up to 25% of upward vertical lens shift and up to 60% of downward vertical lens shift.<br><br> For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image up to 14.00 inches (0.36 meters) above or 33.60 inches (0.85 meters) below the screen center. Horizontal Lens Shift: The Q-750i provides up to 12.5% of horizontal lens shift left or right. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image up to 12.50 inches (0.32 meters) left or right of the screen center.<br><br> ¤ Base plate to lens center = approx. 5-6" (depending on the amount of lens shift) 50% Height Lens Shift (0.5 x H) 100% Height Lens Shift (1.0 x H) Screen Center 0% Note: This is a general example of lens shift.

Note Installation 18Q-750i Series Installation/Operation Manual PRELIMINARY Folded Optics In 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.<br><br> If you are considering this type of installation, contact your dealer for assistance. Figure 3-5. Folded Optics Other Considerations Other considerations and tips that can help improve your installation: "Keep the ambient temperature constant and below 35°C (95°F).<br><br> 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.<br><br> Common sources of these include slide projectors, speakers, power amplifiers and elevators. ¤ Screen Mirror ¤ Installation Q-750i Series Installation/Operation Manual19 PRELIMINARY 3.4 Installing the Optional CineWide/AutoScope Lens Mount If you are installing a standard (non-CineWide) Q-750i, skip this step and proceed with Mounting the Q-750i (page 26).

Use only the hardware provided with the CineWide lens base plate. 2.<br><br> DO NOT OVER-TIGHTEN THE SCREWS. Caution Installation 26Q-750i Series Installation/Operation Manual PRELIMINARY 3.5 Mounting the Q-750i There are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another.<br><br> 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 9s in position to prevent it from being moved during a presentation.<br><br> 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 Q-750i and suspend it from the ceiling using a specially-designed ceiling mount fixture. 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.<br><br> A variety of materials can be used for this purpose (for example, rubber crutch tips or turntable feet). Adjusting the Projector Height or Projection Angle If the screen is significantly higher or lower than the projector (such as in a rear-projection installation), you can tilt the projector at an angle. In a ceiling installation, you do this by adjusting the ceiling mount.<br><br> If you do tilt the projector, you may need to vertically shift the image using the on-screen display (OSD) controls, to compensate. For detailed instructions, refer to Using the On-Screen Menus on page 45. 3.6 Connections to the Q-750i Proceed as follows to connect the Q-750i to your video sources, external controller(s) 3 if present 3 and AC power.<br><br> When connecting your equipment: "Turn off all equipment before making any connections. "Use the correct signal cables for each source. "Ensure that the cables are securely connected.<br><br> Tighten the thumbscrews on connectors that have them. Connector Panel Access To access the connector panel, pull firmly on the cable access cover to open it. ¤ ¤ Use only the Runco-approved ceiling mount kit designed for your projector.<br><br> Install the mount kit according to the instructions provided with it.
