Default Factory settings are in bold.
Note 1: correspond to a -10 dBV nominal level, with headroom of 14 dB.
Note 2: correspond to a +4 dBu nominal level, with headroom of 14 dB.
Note 3: Normal ADAT mode is the default: The audio flow in this mode is represented in Appendix 2.
Note 4: Stand-Alone mode: This mode should be selected when no ADAT compatible device is used, such
as A/D-to-AES/EBU and AES/EBU-to-D/A configuration.
In this mode, the ODI output is internally looped to the ODI input.
It is however possible to lock to an ADAT signal connected to the ODI input, but its audio content
will be ignored. The ADAT formatted signal is present at the ODI output, as in the Normal mode.
