Like the old EQ1-DS, the EQ1-MK2 supports 44. 1, 48, 88. 2 and 96kHz sampling frequencies, always using either 88. 2 or 96kHz for internal processing. This is responsible for the well-renowned sound of the high resolution units and is the difference to the standard sampling EQ1. [. . . ] The graph of the snapshot will be displayed in preview mode (outlined) to facilitate finding a certain setting. However, the audio signal is not affected if the "Preview" option is marked. Once you have found the snapshot, press key D to restore it. Graph 7: Store To Range Menu Press the adjacent keys to select "Start" and "End" snapshot number, use the "gain/ data" encoder to enter a value (Graph 7). Pressing "Execute" will store the setting from the displayed workspace ("A" or "B") to all snapshots between the Start and End value. Backup All 128 snapshots can be transferred to another non-volatile memory area for later reference. There is enough memory for two complete snapshot sets to be backed up. Press the "menu" key then choose the "System" and then the "Backup" option to arrive at the backup display (Graph 8).

The EQ1 will automatically switch into receive mode and display statistics about the snapshots it's receiving. If the transmission was OK and no errors occured, the program switches back to normal mode. When playing back the dump sequence, always use the same speed as when the sequence was recorded. Graph 8: Backup Display Select "Create 1" to save the current snapshots to bank 1. Select "Restore 1" to overwrite the current snapshots with bank 1 (ditto for bank 2). Reset To reinstall the factory snapshots you must press the "menu" key then choose the "System" and then the "Reset all" option. Dumping The settings of all 128 snapshots can be dumped to a remote control port to be stored externally. Please make sure that you have connected everything correctly and that the proper remote control port is activated (see chapter Remote Control for setup). When dumping to a MIDI-sequencer, make sure that the sequencer is not sending or receiving data other than the snapshot dump. Certain sequencers are not capable of handling the amount of data output by the EQ1 and might crash during or after the dump process. Always save the sequencer settings before recording a dump! To initiate a dump, press the "menu" key then choose the "System" and then the "Dump" option. Start the recording process on the sequencer, then press "Transmit". This releases the dump to the sequencer.

Word Length To set output word length, press key D and choose either 16bit or 20bit. Auto-Blacking If auto-blacking is activated by marking the "0 IN à 0 OUT" option, dither will be turned off if the input signal is digital zero for more than 256 consecutive samples. [. . . ] Graph 9 shows a 24bit sine wave at ­85dBFS truncated to 16bit. Graph 9: Sine wave truncated Graph 10 shows the same sine wave, but dithered to 16bit. This eliminates quantization distortion.
