YDG2030 9 ­ Utilities Utilities The [UTILITY] key allows you to set up various system parameters for the unit. Repeated presses of the key will cycle you through the following modes. You can also use the [%] and [%] keys to cycle through these parameters (but this will not return to the equalization setting display): The [UTILITY] key will be lit for all these displays SYSTEM SET UP Equalization setting display DELAY DISPLAY MIDI CONTROL SOFTWARE PROTECT PARAMETER COPY TITLE EDIT BULK DUMP Y-485 NETWORK Y-485 COMM. I/O NOTE You can also exit the UTILITY mode by pressing the [DISPLAY] key. SYSTEM SETUP Only one parameter is available here: EMPHASIS. The emphasis function is a type of noise reduction and can effectively be used to reduce the high-frequency noise produced during A/D conversion and D/A conversion. It causes some deterioration of the dynamic range in the high-frequency range, however. Because this equipment uses a 20-bit AD/DA converter, a sufficient dynamic range is assured even when the emphasis function is turned off. Setting it to OFF will work best for most material most of the time. Use the F encoder to turn emphasis on and off (this trips an internal relay, so you will hear a "click" as this is switched). TITLE EDIT Each equalization setting may have a name. This may be useful in a mobile PA setup which is often used at the same venues at different times (a setting named "UNIV. STADIUM" is easier to remember again than program 23). Names set using this function are displayed on the screen whenever you step through the memory areas using the [%] or [^] keys. Use the F encoder to select a character (0-9, A-Z, a-z + punctuation) and the [L/<] and [R/>] keys as cursor keys to determine which character will be edited. Use the [STORE] key as an easy way to enter a space. YDG2030 10 ­ Utilities ­ BULK DUMP BULK DUMP Three parameters are available here: Use the F encoder to select whether bulk dump operations will take place through the MIDI or Y-485 connections. Use the G encoder to select what kind of data will be dumped. You can choose between: ALL DATA (all memory areas will be dumped), SYSTEM (the parameters you set up in the UTILITY menus will be dumped), MEMORY (a single memory area, or all memory areas will be dumped), and BANK (the Program Change tables). If you have selected MEMORY with the G encoder, use the Q encoder to select the memory area that you want to dump (1 through 40 or ALL). If you have selected BANK with the G encoder, use the Q encoder to select the Program Change bank you want to dump (A through D or ALL). NOTE You can dump this data over MIDI to a MIDI data filer device (including a personal computer), or over the Y-485 network to a computer connected through the YAMAHA IFU485 interface. There is no need to set the unit into any special receive mode to receive bulk dump data from an external device. Y-485 NETWORK The Y-485 network is more complex (in terms of software addressing) than the MIDI system. Each device on a network belongs to a group and has a device number within that group. Use the [L/<] and [R/>] keys to decide whether you are editing the REMOTE or LOCAL settings. The LOCAL settings, of course, refer to this unit, and the REMOTE settings refer to a unit to which you will be sending data. The F encoder allows you to set up a group number between 1 and 7. The Y-485 protocol allows messages to be sent to groups of units. If you are editing the REMOTE settings, you can also set this to a "*". [. . . ] 3 Use the F rotary encoder to alter the frequency of the filter. 4 For the notch filters, use the Q rotary encoder to alter the Q of the notch. The figure shown is adjustable from 0. 5 to 10. 0 (10. 0 is the narrowest). Of course, the HPF and LPF shelving filters do not take Q values. YDG2030 18 ­ TUTORIAL ­ Setting up the input level, attenuation and delay Setting up the input level, attenuation and delay I. Input level and input attenuation There are two operations on the YDG2030 that affect the input level--the input level control in the analog domain (pre A/D converters), and the attenuation parameter (INP. ATT) in the digital domain (post A/D converters). [. . . ]
