• The projector must be within 10 feet (3 m) of your power source and within 6 feet (1.8 m) of your video device (unless you purchase extension cables). • If you are installing the projector on the ceiling, refer to the installation guide that comes with the Ceiling Mount Kit for more information. To turn the image upside down, see “Ceiling Project” on page 46. Studio Experience recommends use of an authorized ceiling mount. The Ceiling Mount Kit is sold separately, see “Optional Accessories” on page 63. 2 Position the projector the desired distance from the screen. • The distance from the lens of the projector to the screen, the zoom setting, and the video format determine the size of the projected image. Figure 5 shows three projected image sizes in 16:9 format. For more information about image sizes at different distances and formats, see “Projected Image Size” on page 64. NOTE: To ensure adequate cable access, do not place the projector within 6 inches (.15m) of a wall or other object. NOTE: The projector must be at least 6.5 feet (2 m) from the projection screen. 5ft. 10.1ft. 7.5ft. 7.4 ft. 11 ft. 15 ft. FIGURE 5 Projected image size at minimum zoom Setting up the Projector The image exits the projector at a given angle. This image offset is 125.5% when the projector is in 16:9 mode (the default mode). This means that if you have an image 10’ high, the bottom of the image will be 2.55’ above the center of the lens. The value is 113.7% for 4:3 mode. lens center bottom of image 2.55’ above lens 10’ high image FIGURE 6 Projection angle in 16:9 mode 3 Make sure the projector is unplugged and your equipment is turned off. WARNING: Do not place the projector on a tablecloth or other soft covering that may block the vents. Do not use a non-Studio Experience ceiling mount. In the unlikely event of the bulb rupturing, thoroughly clean the area in front of the projector and discard any edible items placed in that area. Connecting the Enhanced Connectivity Module The connector panel on the back of the projector looks like this: NOTE: Before you continue, Audio in computer S-video composite make sure the projector is video unplugged and your equipment is turned off. FIGURE 7 Connector panel The projector ships with an enhanced connectivity module. When you attach it to the back of the projector, it looks like this: computer 1 component Control (RS-232) computer 1-M1 audio in not used video composite computer 2-VGA computer 2 monitor S-video video audio in audio in (for all video sources) FIGURE 8 Connector panel with enhanced connectivity module attached This module adds all the connectivity you need for your home theater applications. Setting up the Projector NOTE:If you have turned Auto Source off (page 45), you may need to press the source button more than once to display an active source. The sources switch in this order: PC 1-Analog, PC 1-Digital, Video 3-Component HDTV, Video 3-Component, Video 1 S-Video, Video 2-Composite, PC 2-Component, and PC 2-Analog. The module connects to the projector via the projector’s computer connector. Slide the tabs in the module into the grooves on the back of the projector, then press the computer connector into the projector. To remove the module, press down all the way on the textured lever on the top left of the module to release the latch, then slide the module off. FIGURE 9 Connecting the connectivity module to the projector The module provides two computer and three video inputs (see page 63 for a list of sources and audio/video connectors). The module also provides monitor out (used to display images on your desktop computer’s monitor as well as on the projection screen), and RS-232 input (to control the projector from an LCD control panel). NOTE:Monitor out is only available for analog computer, 480p, and HDTV sources. Connecting a Video Device You can connect VCRs, DVD players, camcorders, digital cameras, video games, HDTV receivers, and TV tuners to the projector. There is an audio input. You can connect the audio directly to the projector to get sound from the 3-watt onboard speaker, or you can connect it to your stereo’s receiver to get sound from your own speakers. Before connecting your projector, you should decide which screen aspect you want to project. Screen aspect is the ratio of the image width to image height. TV screens are usually 1.33:1, also known as 4:3. HDTV and most DVDs are 1.78:1, or 16:9. If you’re projecting onto a screen, the size/shape of the screen may answer this question for you. If you are projecting onto a blank wall, you don’t have the screen size restriction. What you plan to project will also help you choose between 4:3 and 16:9. Most regular TV shows are 4:3, most movies are 16:9. If you select 4:3 and play TV, the image will fill the screen. If you select 16:9 and play HDTV, the image will fill the screen. However, if you select 4:3 and play a 16:9 DVD, the image may be compressed horizontally or have black bars along the top and b...
