Figure 13 – Multi-channel Sample Rate Conversion with bit aligned source
If the source data is bit aligned (for example, from a multitrack recorder) up to
four or five dCS 974’s may be set to operate synchronously using the sync link
connections shown above, from one unit’s AES CLK Out to the next unit’s AES
Ref Loop In. For all units, set the Multiple Channel Sync option to On. The
top unit will set up as a master, the other ones will set up as slaves. Make sure
that all the other settings are the same on each unit.
See the section Multiple Channel Sync’ing, page 81 for how aligned is bit
aligned.
These are set up, for PCM in to DSD out, in Store E, and for PCM in to 96kS/s
out in Store F.
