Dithering Digital Outputs
When digital audio is transferred to lower-resolution systems, truncated bits may generate
unpleasant noise. To cancel the audible effect of this noise, a small complement of noise is
intentionally added to the digital outputs. This process is called “dithering.”
On the DM1000, you can dither the 2TR Digital Outputs and Slot Outputs. For example,
you can apply dithering to the DM1000 stereo mix data and record to a 16-bit DAT recorder.
1 Press the DISPLAY ACCESS [DIO] button, then press the [F2] button.
The DIO | Format page appears. The dithering settings are displayed on the bottom of the
page.
2 Move the cursor to the output or channel to which you want to apply dith-
ering, and rotate the Parameter wheel or press the [INC]/[DEC] buttons to
select the value that matches the resolution of the receiving device.
Setting the Transfer Format for Higher Sampling Rates
To operate the DM1000 at higher sampling frequencies (88.2 kHz or 96 kHz) and transfer
digital audio signals to and from connected external devices, you must set the data transfer
format in accordance with the sampling frequencies supported by the external devices.
1 Press the DISPLAY ACCESS [DIO] button, then press the [F1] button.
The DIO | Word Clock page appears.
2 Select INT88.2k, INT96k, or an external device running at the higher sam-
pling rates as the wordclock source.
Note:
• You cannot apply dithering to outputs or channels that are set to “OFF.”
• Dithering is effective only when the resolution of the receiving device is lower than that of
the DM1000.
Tip: To copy the currently-selected setting to all channels, double-click the [ENTER] button.
The copy confirmation window is displayed.
