Optical I/O /External Effects settings: NOTE, if you are going ABOVE 48kHz per the manual on the MR. In order to get SMUX which is above 48kHz since your running 96kHz. the ADAT setting on the MR is up to 48kHz only and 8 channels. The following should apply. Im guessing your daisy chaining the FW on the two MR units?
Are you daisy chaining the WordClock from Mr to Mr to the Ur?
ADAT (1-6)
- S/PDIF
(coax) or
ADAT (1-4) - S/PDIF
(coax
When this is selected, the ADAT format signal
of 6 channels (when the Sample Rate is set to
44.1kHz or 48 kHz) or 4 channels (when the
Sample Rate is set to 88.2 kHz or 96kHz) will
be input/output via the OPTICAL IN/OUT jack.
Furthermore, the S/PDIF format signal of 2
channels will be input/output via the S/PDIF IN/
OUT jack in stereo
