User manual PEAVEY PC 1600X

[. . . ] 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. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. [. . . ] A flexible "parameter format" allows the current fader position to be inserted into the message in one of many different formats. " Next, press the up direction button when the function field is not blinking. The left /right direction buttons are used to select a specific byte, while the up/down direction buttons, the data wheel, and the current fader are used to edit a digit of the string. Pressing the up button when between bytes inserts a byte and pressing the down button deletes the byte to the right of the cursor. Replace with "pr" any byte that will be determined by the fader position. This is done by incrementing the byte until "pr" is displayed. When the string is finished, press Exit. Access the minimum and maximum parameters by pressing the up direction button when the underscore cursor is not displayed. Use the data wheel or the up/down buttons to enter the exact value. When neither field is flashing, press the up direction button to access the parameter format page: FDR01: Param format Single Byte 7. The value selected here determines how the "pr" bytes will be filled with the parameter value. Refer to your unit's owner's manual to determine which format to use. for a detailed description of the parameter formats , see Appendix B. DEALING WITH CHECKSUM VALUES Some products call for checksum bytes in their SysEx implementation. In order to specify a byte as checksum, a "cs" can be added to the string. " Here is an example string with an extended display to show you the entire string: FDR01: String F0 41 10 70 12 00 00 01 pr cs F7 The PC 1600xTM will compute the checksum as follows: *Adds up all bytes from byte #5 (or higher, see below, when F0 is byte #0) to the last byte before the "cs. With some SysEx messages, the unit ID (byte #3), and command ID (byte#4) could be extended beyond a single byte by using leading zeroes before the non-zero byte. In this case, the PC 1600x's checksum calculation will start later in the string accordingly: at byte #(5 + number of leading zeroes). note: The "cs" computation is unavailable in button and set-up strings. In these cases, the checksum must be calculated and inserted into the string as a constant by the programmer. Be sure and refer to your product owner's manual for the necessary values/messages. ASSIGNING STRING DEVICE IDs AND MIDI CHANNELS TO GLOBAL SETTINGS Many devices use SysEx command strings that include a MIDI channel or device number as one of the bytes. [. . . ] Never break off the ground pin on the power supply cord. For more information on grounding, write for our free booklet "Shock Hazard and Grounding. " Power supply cords should always be handled carefully. Never walk or place equipment on power supply cords. [. . . ]
