[. . . ] OWNER'S MANUAL DSP 244 24 BIT DIGITAL SOUND SYSTEM PROCESSOR 1-1 IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the literature accompanying the appliance. 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. For US and CANADA only: Do not defeat the safety purpose of the grounding-type plug. [. . . ] You are now faced with different possibilities to continue: - For saving the edited program, proceed with chapter 7. 3. This cancels the function and discards all previous parameter value changes of the selected program. NOTE: In the Edit menu, pressing the STORE key (8) lets you directly jump to the Store menu to save your program under a new name and in a new location. 7-3 OPERATION 7. 3 STORE PROGRAMS AND PROGRAM NAMES Whether you want to store an edited program, alter the name of a program, or copy a program from one preset location to another - in all cases the necessary procedure is the same. Pressing the STORE key (8) always starts and executes the saving procedure. You can also quit the Store menu without saving your result by pressing any other key. For saving the program without changing its name in the actual preset, proceed with step 6. If you only want to change the program's name and keep its location, proceed with step 4. For instance, the display might look like this: Please, proceed with step 6 if you do not want to change the program's name. Use the SELECT keys (5) and (6) to position the cursor to the first or the last character of the program name. Use the rotary encoder (10) to select the desired character at the cursor position. Pressing the rotary encoder enters a blank character at the actual cursor position. Use the SELECT keys (5) and (6) to move the cursor between characters to be entered; e. A safety dialog is displayed asking you, if you want to save these changes. 7. The saving procedure is executed by pressing the STORE key (8) again. 7-4 OPERATION CAUTION!The program that was previously stored in this preset location is being erased!Please make sure, that the selected destination program number matches the number you want to save the program under. Pressing any other key cancels the saving procedure. After saving is complete, the Store menu is automatically quitted and the display might look for instance like this: 7. 4 MODIFYING FACTORY PRESET PROGRAMS The easiest and quickest way to achieve good results with the DSP 244 is the use of a factory preset program. Factory preset programs are carefully designed, factory-pre-set programs that are stored non-volatile in the FLASH memory of the DSP 244. Just select the preset that matches your loudspeaker combination and the DSP 244 automatically sets all parameters to their optimal values matching your components. Afterwards, your sound reinforcement system is ready for operation immediately. If you want to make your own settings or re-adjustments, this can be done in the Standard or Full-Edit modes at any time. To apply changes to a factory preset, it first has to be copied to a user-definable preset location and the name has to be changed too. This is necessary to eliminate the chance that programs are mistaken by each other. [. . . ] Now, you can turn the printed board assembly 80448 so that the needed contacts for installing the transformer are accessible. Remove the two resistors of the specific input channel (IN 1: R104 / R105, IN 2: R204 / R205). Clean the holes for the transformer from soldering tin by suction (7 holes per transformer). Insert the transformer for IN 1 into the holes at position T101 or for IN 2 at position T201. [. . . ]
