can also be used to sync the source and the dCS 974
units as above. In addition to the sync link cabling (starting with “A”), additional
clocking (cables “C”) allow the dCS 974‘s to extract clocks from the “C” cables
and extract the data from the signal input cables. The master clock outputs
different frequencies on the different cabling types. This allows considerable bit
alignment error, as might occur if some tracks are stored on one machine and
some on another. For all dCS 974 units, set the Sync Source to Wordclock and
the Multiple Channel Sync option to On. They will all set up as slaves. Make
sure that all the other settings are the same on each unit. Note that cable ‘A’
must NOT be driven from the dCS 992’s AES1 output.
