22 Projector Installation — Introduction Physical and electrical installation of the TransVision™ 4 must be performed only by a trained professional who is knowledgeable about both the specifics of the TransVision ™ 4 and the requirements of the local building and electrical codes. Physical installation of the TransVision ™ 4 may be divided into 3 steps: (1) Pre-installation planning, which includes plotting the projector-to-screen distance. This requires knowledge of the screen size and placement. From this step you will determine where the projector is located. For throw distance calculation and physical mounting dimensions, please refer to the customer support section at www. dwin.com . (2) Preparation and Installation of the ceiling mount bracket, including drilling holes, securing the bracket to the ceiling and assembling the mounting hardware. (3) Final Adjustments. Once the physical installation is complete, the unit should be properly adjusted. Focus: Use the front ring of the lens. Positioning: Use three dimensional physical adjustments made possible by the mounting hardware. Size: Use the zoom ring of the lens; Vertical Offset: The vertical offset is fixed and may be calculated from the following formula: Offset = .081 x W +4.5” . The calculation includes DWIN’s 2 inch Ceiling Mount Bracket. Please refer to the “projector calculator” sec - tion under “customer support” at www. dwin.com . (1) PRE-INSTALLATION PLANNING A. Screen Considerations Although the following advice is no substitute for a dealer’s recommendation for your home, here are a few guidelines for creating a front projection home theater that should be helpful to your early planning: A1. Screen Color and Material: Because the superior design and quality of DWIN’s proprietary optical system results in excellent contrast and black levels, images will look best when projected on a matte white screen from a reputable manufacturer. Many competing projector companies recommend gray screens but a properly projected picture will always look better when colors are balanced for white, just like in a movie theater.
23 Projectors with fixed-pixel imaging arrays, such as DLP or LCD, are not recommended for use with perforated screens. Perforated screens have highly regular microscopic patterns that conflict with the equally uniform pattern in the digital image array. This creates interference, a visual artifact called a “moiré” pattern, which compromises picture quality. To eliminate light spill, a black felt border is also recommended to enhance the viewing experience. A2. Screen “Gain”: Projection screens do not generate light; they only reflect projected light. Therefore screen gain refers to relative reflectance to a reference standard. The most common reference standard is Magnesium Carbonate (MgCO3). DWIN recommends a screen “gain” of 1 to 1.3. A3. Screen Dimensions and Position You should consult your authorized DWIN dealer or professional installer for his or her recommendation. Most screen manufacturers and theater design - ers agree that screens should be installed to create a comfortable viewing angle from a SEATED position. Here are some general guidelines: • A screen should be wide enough to allow viewers to immerse themselves in the program without having to move their heads from side to side. As a rule of thumb, the viewing distance should not be less than two times the screen width. For example, if your home theater has a 100-inch wide screen you should have your seats installed no closer than 200-inches from the screen. • When specifying screen width, remember to allow enough space on the wall for left and right front speakers, and for the screen to blend with the aesthetics of your theater environment. Choose a dark, neutral color (and matte, non-reflective) background wall surface. Bright wall colors or reflective decorations can be distracting and could alter the appearance of the image. • A screen should be installed high enough to allow a comfortable view - ing angle for people sitting in the front row. Eye level (from the seated position) should be approximately 1/3 of the screen’s height measured from the bottom of the screen. • Your Authorized DWIN Dealer or Custom Installer should be able to consider all your home theater design needs and provide you with professional recommendations to enhance your investment.
24 B. Mounting and Throw Distance Calculation Before starting the installation you will need to calculate the projector throw distance and the ceiling to top-of-picture offset. The throw distance and the precise center of the screen are then used to determine the exact location for the physical installation of the projector. The TransVision ™’s zoom lens allows for a wide range of throw distance op- tions — the distance from the projector to the screen. For maximum flexibility in adjustment we recommend that, where possible, the projector be installed in the middle range of the possible distances. However, the unit may be installed at any point within the allowable range. • To obtain the minimum throw distance, multiply the screen width by 1.65. • To obtain the maximum throw distance, multiply the screen width by 2.08. C. Screen Offset Screen offset is the distance between the top of the picture area of the screen and the ceiling. This distance is important and it should be calculated before the screen is installed to ensure proper positioning of the projector in relation to the screen. Incorrect screen offset may cause image keystone distortion and cannot be compensated either with the mounting system or electronically. The TransVision ™ 4 is a 16:9 Projector and is designed to be used with a 16:9 screen. • The screen offset is fixed and may be calculated from the following formula: Offset = .081 x W +4.5”. The calculation includes DWIN’s 2 inch Ceiling Mount Bracket. • Please refer to our TransVision ™ 4 Calculator, under the Customer Sup- port section at www.dwin.com for assistance with calculating these dimensions. NOTE: The ceiling mounting system enables you to make small adjustments to the vertical tilt without introducing visible keystone distortion. �������������������� ������ ������ � � �
25 For floor-mounted installations the picture offset is the distance between the mounting surface of the projector and the bottom of the picture. In order to deliver pictures that are free of keystone distortion, be certain to calculate the offset distance before ordering screens and/or cabinetry. Although some adjustment range is available in floor mounted systems by using the adjust - able feet. (2) PREPARING FOR CEILING MOUNT INSTALLATION 2A. Cable Installation The TransVision ™ 4 digital video processor sends a high definition video signal via a DWIN-proprietary DVI-D cable. For easy installation in walls, the cable has a ¾” inch round connector that connects to the front (lens side) of the projector. DVI cables (with the ¾” round connector) are available from DWIN in lengths of 25-feet to 50-feet in five-foot increments. A separately sold DVI Cable Ex - tender box is also available to support cable runs of up to 100-feet. In new home theater construction, many installers choose to install the DWIN DVI cable during the pre-wiring phase when beams and crawl spaces are readily accessible. Cables can be ordered several months in advance for this purpose. NOTE: The DWIN DVI cable must be used to connect the projector and the video processor. DWIN STRONGLY RECOMMENDS TO RUN THE DVI CABLES THROUGH A 1-INCH OR LARGER DIAMETER CONDUIT. A CONVENTIONAL DVD-D CABLE WILL NOT WORK. FURTHER, DUE TO SIGNAL-DEGRADA - TION ISSUES, A CONVENTIONAL ‘GENDER CHANGER’ ADAPTOR IS NOT RECOMMENDED. Do not coil, tightly bend or crimp the DVI cable; it may damage or short the wires and compromise the shielding. Do not straddle staple the DVI cable. Doing so may puncture the cable, damaging or shorting the wires and com - promise the shielding. During installation inside walls, care should be taken to avoid excessive strain which may damage to internal cable wires. When the DVI cable is being “pulled” or “snaked” DWIN recommends that the snake be connected as far down the length of the DVI cable as possible to prevent stretching damage to the cable or the connector. Further, the DVI-D connector is extremely delicate. Care should be taken to avoid dropping the connector on hard surfaces to avoid damage. To prevent interference, DWIN strongly recommends that the DVI cable not be run in close proximity or tied to any AC power lines! DWIN strongly recom - mends that the DVI cable be run through a dedicated (DVI cable only) conduit that meets NEC or local electrical code requirements .
26 2B. Ceiling Mount Preparation Once the throw distance has been calculated and the screen installed, the next step in the installation is to locate the precise mounting position of the projector. The ceiling mount bracket must be aligned to the middle of the screen and located as close as possible to an electrical source AND a support beam. If the projector is not located properly, it is not possible to compensate for any resulting “keystone” distortion in the projected image. IMPORTANT NOTES: 1. Before proceeding further with the installation, make certain that video signal/ control wiring and AC power have been run to the projector location. Keep in mind that the connections to the projector are at the back of the unit. 2. In rooms where the projector is mounted near a rear wall, be sure to allow adequate clearance for proper ventilation. Allow at least 24” of rear-facing clearance. (See Figure 2). Improper ventilation is a cause the TransVision projector to overheat, shortening lamp life and reducing the reliability of electronic components. Projector failures due to overheating will invalidate the manufacturer’s warranty. 3. When the unit is mounted inside a cabinet, be certain that an exhaust vent is provided so that the hot air generated by the projector may be safely removed from the cabinet. DO NOT RECIRCULATE AIR FROM WITHIN THE CABINET. Failure to properly design an enclosure will cause projector overheating, resulting in premature lamp failure and wear of electronic components.

27 2C. Ceiling Mount Installation and Projector Mounting The optional ceiling mount kit (CMB) consists of three parts. Before beginning the installation process, first identify each of the three parts of the mounting system as shown in the pictures below. NOTE: The ceiling must be capable of safely supporting the weight of the projector and mount, which is approximately 25 pounds.
