Channel Ordering
spdif channels first – If this box is active, the interface's S/PDIF port will appear in your DAW first,
<
followed by the optical, and then the analog outputs. That is, the S/PDIF port will be assigned to audio
channels 1-2, while the optical ports are assigned to 3-10, 11-18, 19-26 and 27-34. By default, the
analog outputs are configured to mirror the S/PDIF output and will carry signals sent from your DAW's
output channels 1-2. If the "mirrors spdif output" checkbox is deactivated, then the analog outputs will be
designated to output channels 35-36".

followed by the S/PDIF and analog outputs. That is, the optical ports will be assigned to audio channels
1-8, 9-16, 17-24 and 25-32, with the S/PDIF and analog outputs assigned to 33-34. If the "mirrors spdif
output" checkbox is left unchecked, the S/PDIF outputs will be assigned to 33-34, while the analog
outputs will be designated to output channels 35-36.
Note: When running Mac OS X, the channel numbering and port arrangement may vary, depending on
the number of active digital ports.
