Audio/Data mode
In data mode, all digital level processing is disabled in the driver to ensure a
digital stream free of any sample modification. This mode must be used to
play non-PCM audio data on the digital output (Dolby AC-3 for instance).
Note: Do not listen to the analog output in such a case, as clicking may cause
disturbing noises!
Digital format
Sets the digital format of the digital output in real time: AES/EBU
(professional) or S/PDIF (consumer).
Nominal Out and Headroom Out
Sets the nominal line output level and the available headroom during
playback at nominal level. Addition of headroom and nominal level must not
exceed the maximum output level of the board (+22 dBu).
Note: The sum of Nominal Out plus Headroom Out defines the equivalence
between the maximum analog level and the maximum digital level
(0 dBfs).
Nominal In and Headroom In
Sets the nominal input level for recording and the available headroom while
recording at nominal level. Addition of headroom and nominal level must not
exceed the maximum input level of the board (+10 dBu or +22 dBu,
depending on the position of the jumper (SW1, cf. appendix) on the board)..
Note: The VX222
v2
does not dispose of an adjustable analog input gain. A
modification of Nominal In or Headroom In applies the digital input gain.
On VX222
v2
, the sum of Nominal plus Headroom must be situated
between -8 dBu and +10 dBu if the jumper is in "-10" position (=absent),
or b4 dBu and +22 dBu if the jumper is in "+4" position (=on the
board).
The sum of Nominal In plus Headroom In defines the equivalence between
the maximum analog level and the maximum digital level (0 dBfs).
