Sample Rate Conversion / Format Conversion Submenu
The
Sample Rate Conversion
menu is as follows:
Audio Input Select
Select the required input from the list and press
Set
. The
Dual AES
option
requires that the
Input Sample Rate
be set to
192 kS/s
,
176.4 kS/s
,
96 kS/s
or
88.2 kS/s
. The
Quad AES
option requires that the
Input Sample Rate
be set to
192 kS/s
or
176.4 kS/s
. The
DSD
setting automatically identifies DSD SDIF-2 or
DSD SDIF-3 data on the DSD/SDIF input.
Sync Source
Select a source to synchronise to from the list and press
Set
. The available
sync sources are:
Audio Input
Syncs to the selected input source – this is the
normal setting.
normal setting.
AES Loop

Loop Out
to another device.
AES Loop Term
Syncs to the
AES Ref Loop In
and terminates the
reference source.
Wordclock
Syncs to
DSD/SDIF WCLK IN
(in the upper group
of connectors).
Internal
Syncs to the dCS 974’s internal clock.
Lab Ref
Syncs to a 10 MHz signal into
DSD/SDIF CLK IN
(in the upper group of connectors).
For best results, synchronise to the
Audio Input
or a master clock on one of
the clock/reference inputs that is also driving the source. For DSD/SDIF inputs,
you can still sync to
you can still sync to
Audio Input
as the unit will automatically sync to
DSD/SDIF WCLK IN
. For DSD in SDIF-2 or SDIF-3 mode, a Wordclock must
be used – contact dCS if you need a Bit Clock.
The
Lab Ref
setting allows use of a GPS reference - if you use this, make sure
other parts of your system are also GPS sync’d.
Only select
Internal
sync if you are using the unit as a signal generator or a
reference clock source.
