    Expandability ➤ Madrigal Imaging projectors can be expanded or upgraded to include addi- tional features, accessories, and input options; these include a variety of quick plug-in interface modules to suit the input devices you are using, a signal switcher, a video decoder, a ceiling mount, and floor mount acces- sories.

  • Page 7: Installation & Setup

    This section explains how to install and set up the projector. If you are familiar with the projector and want to quickly set it up for temporary use, follow the Quick Setup instructions in section 2.1. For a complete setup, skip section 2.1 and follow the instructions and guides covered in the remaining subsections.

  • Page 8: Installation Considerations

    Although the projector offers high performance, the final Considerations display quality will be compromised if the projector is not installed properly. This subsection discusses the considerations you should make before proceed- ing with a final installation. These considerations include the installation type (floor, ceiling, rear), screen size and type, room lighting, and ventilation.

  • Page 10 Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation, is created.
  • Page 11 Notes: 1) Calculated values are for reference only. It is good practice to simulate the setup to determine the necessary throw distance. 2) Display size is affected by input signal characteristics. Once the projector is set, use the Size function to fine tune display size.
  • Page 12 Figure 2-3 shows an installation where poor screen placement has allowed too much unwanted light to enter the screen. In Figure 2-4, the screen and the projector are positioned so that unwanted light is minimized.
  • Page 13 Common sources of these are slide projectors, speakers, power amplifiers, elevators, etc. Keep 35 mm slide projectors at least 2 feet away from the projector. Even if both are not used at the same time, the magnetic fields created by the slide projector can cause permanent magnetization of the projector.

Keypad ➤ The projector includes a multi-use full-function keypad which may be configured for use as a built-in, IR remote, or wired remote keypad. The Conversion keypad is configured at the factory for built-in use. It is located below the front top cover.
  • Page 15 Follow the steps below to convert the keypad to a remote keypad and change its protocol setting. Step 1 Unplug the projector then lift the front top cover to access the built-in keypad. To lift the cover, grasp it above the red and blue lenses then lift it until the keypad is exposed.
  • Page 16 For a wired remote keypad, an optional accessory cable (#03-001106-02P) is required. Plug the cable into the cable connector then position the door into place. Plug the cable jack into the remote jack input on the projector. WARNING: DO NOT INSTALL BATTERIES IN THE KEYPAD IF A BUILT-IN OR WIRED REMOTE CABLE IS ATTACHED TO IT.
  • Page 17 If the projector is not installed in a front screen, floor mount configuration, reverse scan setup may be required. Reverse scan setup must be performed by a qualified Madrigal Imaging service technician. Refer to Table 2-2 to determine if reverse scan setup is required. Contact your dealer for assistance.

    Floor Mount Installations Mount the projector on a secured table or cart. Position the projector at the chosen room location with the projector pointing towards the center of the projection screen. The angle of projection, combined with the tilt angle of the screen should direct the reflected image towards the center of the audi- ence.
  • Page 19 INSTALLATION & SETUP Position the projector so that it is pointing toward the center of the projection screen. The angle of projection combined with the tilt angle of the screen should direct the reflected image towards the center of the audience. It is rec- ommended that the difference between the projection angle and the screen tilt angle (within a common reference) be less than 15°.

    3.1 Overview This section explains how to operate the projector once it has been installed and is ready for use. If you have not yet set up the projector, refer to Section 2, Installation and Setup. Before using the projector for the first time, it is recommended that you read through this section of the manual.
  • Page 44 Built-in Keypad When the keypad is configured for built-in use (factory default), it is con- nected to the projector by a 3 foot extension cable, located below the front top cover. This configuration is intended for initial setup of the projector and applications where it is desirable to keep the keypad with the projector.
  • Page 45 Figure 3-2 shows the projector functions which are accessible from the multi- use (full function) keypad. As you may notice from the figure, some keys provide direct access to specific functions (such as on or off ), and some keys provide indirect function access via menus.

    For the purposes of input selection, the projector is considered to be a type of switcher. Projector and switcher slots are illustrated in Figures 3-4 and 3-5 on the next page. Each slot can accept one external input signal for display.
  • Page 53 If the selected input is invalid, a warning message is displayed. An example of an invalid input might be “0 1” when a switcher is connected to slot 1 of the projector. Another example of an invalid input would be to select a switcher which does not physically exist.

    The switcher and slot number of the active input is displayed. If the switch- er number is 0, the input is on the projector (versus on a switcher). The slot number may indicate a projector slot or a switcher slot.
  • Page 57 Recall memories provide an alternative to using the display settings stored in the Input memory of the selected source. For example, you may want to temporarily disconnect a computer connected to the projector’s RGB input and in its place, connect another computer with different signal characteris- tics.

  • Page 69: Convergence Registration

    The projector’s convergence sys- tem provides accurate color registration in 45 discrete convergence zones con- figured in a 9 by 5 array on the projection screen. Since the projector must converge colors differently for each source (due to varying scan frequencies), convergence settings are saved for each input.

Above the box, “CONV” indicates that the zone is ready for convergence. Use the arrow keys to move the red onto the green within the box.
  • Page 73 Before using ACON for the first time it is important to understand how ACON operates. ACON consists of two primary components; a Locator Assembly, normally mounted to the front of the projector, and an ACON Control Board, located inside the projector. The Locator Assembly includes a photosensor which, via two stepper motors, can monitor any point on the dis- play screen.
  • Page 74 OPERATION When ACON (full) is selected, ACON converges the red and blue to the green at all 45 convergence zones. As each zone is converged, surrounding zones are also adjusted by ACON’s proprietary interpolation software. This software provides fast, accurate convergence adjustment of poorly converged images.

  • Page 79 When ASR is on, the projector monitors the current input for horizontal and vertical scan frequency changes. When a frequency change occurs, the current Input memory and all Recall memories are scanned in search of a memory with matching scan frequencies. If one exists, this memory becomes the current setup memory.
  • Page 80 A system has six different sources as shown in Figure 3-7. Source “A” is a video camera. Source “B” is a VCR. Sources “C” through “F” are various computers. All sources are connected to a 3rd party (non-Madrigal Imaging) signal switcher. The switcher is connected to projector slot 1. For each source, a Recall memory is created to store its display settings.
  • Page 81 Source Setup menu is returned. Note: Clearing a setup memory does not “delete” it from the system. If the projector’s 75 memory spaces are used up, and you need to delete unused memories to make room for new memories, call your dealer for assistance.
  • Page 82 The Channel List utility allows you to display and program the projector’s Channel List. The Channel List is a user-programmable list of sources and projector setups. Sources added to the list can be quickly switched to and displayed by entering their assigned two-digit channel number. Channels may also be selected using the keypad’s up and down arrow keys.
  • Page 83 The Input field contains the switcher and slot number of the input to be switched to when the channel is selected. If the input is a direct projector input, the input number is a 0 followed by the projector slot number.
