Does GIGAPort DG have an ADAT input and does it support S/PDIF?
No. GIGAPort DG
provides a single optical 8-channel ADAT compatible digital output, but there
is no digital input. It cannot be used to record signals. Also, the output is
only in 8-channel ADAT format, there is no 2-channel S/PDIF option. You can
connect GIGAPort DG only to devices with an optical ADAT input.
