This menu item sets the sample frequency and sync reference source for digital outputs. The “As
Recorded” setting will play any file using its recorded sample rate during play out.
Files recorded at various sample rates can be converted to a selected rate at play out. Files are not
permanently converted. The sample rate converter is automatically switched into the data path and takes
place “on the fly” during output, if necessary. For example, if this setting is “Output at 48000”, files at all
other sample rates will play out the digital connectors at 48000 samples/second. Files that already match
the selected output frequency will not pass through the sample rate converter (SRC) during play out.
Files recorded at any sample rate may be converted to match an external reference frequency during play
out. Setting this menu item to “Convert to Ref In” or “Convert to Dig In” will place the SRC in the output
path and use the externally supplied signal to clock the output rate. Ref In is the AES-11 BNC connector,
Dig In is the digital audio input on either the BNC or XLR connectors.
The recorded sample rate of the current file is displayed on the LCD. Whenever the SRC is switched into
the signal path, the SRC indicator on the front panel will illuminate. The EXT SYNC indicator on the front
panel will illuminate if the sync source is set to one of the external sources.

This menu item sets the data word width for digital outputs.
Files recorded at various word sizes can be converted to a selected size at play out. Files are not
permanently converted. The word width is automatically formatted into the data and takes place “on the
fly” during output, if necessary. When set to “As Recorded”, files play out in their format. When set to
“16-Bit”, all files will be play in 16-bit format; dithering of 24-bit files will happen automatically.
If the sample rate of the file to be played is 96000 or 88200 then dithering is not performed, regardless of
the PLAY WORD SIZE selection. Whenever dithering is switched into the signal path, the DITHERED
indicator on the front panel will illuminate.
