Figure 11 – Using a Master Clock
If a Master Clock such as a dCS 992 is available and the driving source is locked
to it, the dCS 974 may be locked to it. Either:
to it, the dCS 974 may be locked to it. Either:
do this:
connect the Master Clock to the
AES Ref Loop In
and select
AES Loop Term
as the
Sync Source
,
or:
do this:
connect the Master Clock to the SDIF-2
WCLK IN
and select
Wordclock
as the
Sync Source
.
IMPORTANT!
Since the Output Sample Rate of the dCS 974 is different to the Master Clock
rate, the DAC would be unable to lock to the data from the dCS 974 if it were
sync’ed to the Master Clock. So, slave the DAC to the dCS 974, NOT to the
Master Clock.
