5 Digital boards menu
This menu lets you set up the following for any digital I/O board(s) fitted in the unit:
• Clock source — synchronise the digital outputs from the inputs or set them at 48k
or 96k.
• Sample rate converter (SRC) — switch the SRC on/off for each input/output
channel pair. As this option is ‘intelligent’ it may be disabled, depending on the other
settings.
• Word size — set up the word size for the digital outputs as 16, 20 or 24 bits.
This menu has three boards to choose from — A, B and C — representing the module
slot positions printed on the rear panel.
Note: If there are no digital I/O boards fitted, this menu does not appear.
