Digital I/O Routing
S/PDIF selected (OPT I/O switch out)
RCA In = o
Optical In = S/PDIF (ch. 9-10)
RCA Out + Optical Out = S/PDIF (ch. 11-12)
ADAT selected (OPT I/O switch in)
RCA In = S/PDIF (ch. 9-10)
Optical In @ 96 / 88.2 kHz = S/MUX (ch. 11-14)
Optical In @ 48 / 44.1 kHz = ADAT (ch. 11-18)
RCA Out = S/PDIF (ch. 11-12)
Optical Out @ 96 / 88.2 kHz = S/MUX (ch. 13-16)
Optical Out @ 48 / 44.1 kHz = ADAT (ch. 13-20)
Computer Bus Connectivity
