User manual RANE RPM 26

[. . . ] OPERATORS MANUAL RPM 26 DSP MULTIPROCESSOR QUICK START If you don't read all of this document, you risk setting up your system improperly. But at least read this section and the Input Trim section on page Manual-12. Paying careful attention to your system's gain structure and setting the RPM's Input Trim properly are essential in maximizing the noise performance of your entire system. (See the enclosed RaneNote "Setting Sound System Level Controls". ) Once you're done reading and memorizing the manual, please recycle the paper it is printed on by reconing an old speaker. [. . . ] To help find a desired DSP Program, the Inputs and Crossovers check boxes near the top of the screen allow the user to reduce the DSP Program list to include only those Programs matching the checked criteria. For example, if one desires only two input, 3-way crossovers, de-select all but the Two Input and 3-Way check boxes. The displayed list is then reduced to only two DSP Programs -- both Programs 4 and 5 provide a Dual 3-way Crossover. Generally these descriptions duplicate information available in the simple graphic, but some DSP Programs provide much greater functionality than the simple graphics indicate. For example, some DSP Programs contain "Extended" parametric EQ, shown with a plus sign after PEQ (PEQ+). DSP Programs with PEQ+ permit multi-way crossover implementations since two filters in each Extended Parametric can be changed to crossover filters such as Linkwitz-Riley, 24 dB/Oct. , etc. Each time you change DSP Programs from this window, all settings revert to their defaults and all outputs of the newly loaded DSP Program are automatically muted. This is not the case, however, when recalling a new DSP Program during a Memory change. Important Note: Each of the 16 Memories can contain a different DSP Program. Before connecting the RPM 26 to other audio system components, it is wise to choose the appropriate DSP Program and store this program in each of the 16 Memories. This avoids the problem of accidentally recalling a Memory that restores an undesired DSP Program; such as the case where you recall from a 3-way DSP Program to a splitter: this sends full-range audio to all Outputs! Manual-11 PROGRAMMING THE RPM 26 Each DSP Program contains a number of processing Blocks. The quantity and type of available processing blocks varies from DSP Program to DSP Program. Double clicking on most of these processing Blocks opens a detail window where most processing settings are edited. Assuming your computer screen provides enough graphics resolution, up to three of these detail windows can be open at any one time. In addition, a fourth window that displays the Overall Response curve for a given output can be opened by double-clicking any output's screw terminal graphic. The window can then be closed and the changed settings are retained in the working memory (memory zero). Changes are not stored in any other memory until you save them with the Store button. It is not possible to Alt-Tab to another Windows application while any RPM Detail Window has the focus. You can, however, Alt-Tab from the RPM's main Device Edit screen when it has the focus. This allows you to toggle between Windows applications and still keep the RPM's Detail Windows open on the screen. INPUT TRIM The Input Trim processing block is on the left side of the Device Edit screen, just to the right of the input screw terminal. This block is shown here: The Input Trim operates the RPM's internal analog level control whose sole purpose is to provide the analog-to-digital converter with the proper voltage level. [. . . ] As usual, a password is required for either option. TROUBLESHOOTING POWER LED IS OFF: Check the POWER connection on the chassis, and confirm that the remote supply is connected to a live AC source. Ensure that the DIN power plug is plugged into the unit before connecting AC power. NO COMMUNICATION BETWEEN THE UNIT AND THE COMPUTER: Set the DEVICE ADDRESS to a unique small number, and try polling for units in RaneWare (under Device|Select, then click Poll). Check that the COM port selected in RaneWare in the System|System Setup menu is the one on your computer that is connected to the unit. [. . . ]
