User manual RANE RPM 26V

[. . . ] OPERATORS MANUAL RPM 26v 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-13. 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. [. . . ] There is a Block shown for each available signal processing function. 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. Once a detail window is opened, settings can be edited. 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 possible to Alt-Tab to another Windows application from any RPM 26v window. This allows you to toggle between Windows applications and still keep the RPM 26v 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 26v internal analog level control whose sole purpose is to provide the analog-to-digital converter with the proper voltage level. Click on the up and down arrows to increment or decrement the Input Trim. For more precise control of the Input Trim, double click on the Input Trim block. You may double click anywhere except on the arrows or on the Mute button to open the detail window, shown below. The name of the processing block appears at the top of each detail window, in this case, input Trim A. The horizontal scroll bar adjusts the Trim control in three ways. Clicking the left or right arrows adjusts the trim in ½ dB steps. Clicking between the arrows and the sliding box (Thumb) adjusts the Trim in 5 dB steps. Clicking and holding the Thumb allows you to drag the control. Two meters are shown in the Input Trim detail window. The Input meter on the left shows the voltage level (in dBu) at the screw terminal input of the RPM 26v. Adjusting the Trim control has no effect on this Input meter. [. . . ] If Output 2 flashes yellow, an unrecoverable error has occurred. If this happens, first try to reset the unit by cycling the AC power, (do not unplug the DIN jack to cycle the power). If Output 2 is still flashing after power-up, the unit may need erasing. This reinitializes all of the stored parameters including names, and resets all Memories to DSP Program 3. [. . . ]
