[. . . ] Owner's Manual DC-1 Digital Controller Base & THX Versions Important Safety Instructions Save these instructions for later use. Refer to the manufacturer's operating instructions for power requirements. Be advised that different operating voltages may require the use of a different line cord and/or attachment plug. Do not install the unit in an unventilated rack, or directly above heat producing equipment such as power amplifiers. [. . . ] This will clear and reload all preset effects and all factory settings of Volume, Balance, Contrast, Configuration, etc. When the message FACTORY DEFAULTS RESTORED is diplayed, press DONE to return to normal operation. Depending on the location of the DC-1 in your room, you may need to adjust the front panel Liquid Crystal Display (LCD) for optimum viewing. To adjust this display, press the MENU v, w or SELECT buttons on the Remote to enter the Main Menu. Press MENU w to select FRONT PANEL DISPLAY. LCD Adjustment To adjust LCD contrast, use SELECT to highlight CONTRAST ADJUSTMENT, and MENU v or w to set the contrast of the display to its maximum as seen from your listening chair. Press DONE twice to return to the main menu. If you want to turn the front panel display off, use SELECT to highlight STATUS, then use MENU v or w to select OFF. Press DONE twice to return to the main menu. 17 Installation and Calibration The Video On-Screen Display Lexicon In addition to the front-panel LCD, the DC-1 contains a character generator for a video overlay display on television sets. Since the on-screen display is capable of showing the full menu of options available at any point, calibration of the system is faster and easier if the DC-1 video output is connected to a video input on a television monitor. Adjustments to the on-screen display are made from the Display Adjust menu. To display this menu, press the MENU v, w or SELECT buttons on the Remote to enter the Main Menu. Press SELECT to open the On-Screen Display menu. This menu allows you to choose the position and duration of items displayed on-screen during normal operation, as well as the options of color or black and white display and conformance to local broadcast format. Adjusting the position allows you to move the DC-1 display items to a location where they will not interfere with any other video overlays your system may generate. The STATUS option allows you to choose to have the on-screen display always off, always on, or on for a two-second duration. Note that if you choose to have the display "time out", this will not affect the display of the main menu. Note also that parameter changes will still be performed when you make adjustments with MENU v or w, even if the display is inactive. If you choose ALWAYS OFF, you will not be able to use the video overlay, and even setup will have to be done using only the front-panel LCD. COLOR allows you to have the on-screen display presented in monochrome or color. Press DONE twice to return to the main menu. Video Input Selection and the On-Screen Display When using the Video Monitor output with the On-Screen Display, the DC-1 automatically puts up a blue or grey background when no video signal is present. Occasionally, an incoming video signal may be so weak that it is recognized as essentially no signal, triggering the background overlay. If this occurs, simply reselect the input. 18 DC-1 Digital Controller Installation and Calibration System Setup The DC-1 Setup menu allows you to customize the system defaults to suit a wide range of possible system configurations. Each of the five entries in the Setup menu will be discussed in detail in this section. Use MENU v and w to step the cursor through the Setup menu selections. Once an item is highlighted, pressing SELECT will display a sub-menu for that item. [. . . ] To correct, or if you simply want to start over, restore the factory defaults with the procedure described at the end of this section. Turn the master power switch on the DC-1 rear panel OFF, wait 10 seconds, then turn it ON again. This causes the unit to run a diagnostic self-test routine which takes a couple of seconds. If the DC-1 LCD displays normally at the end of this test, no problems have been found with the DC-1 circuitry. [. . . ]
