Figure 10 – PCM to DSD conversion
The dCS 974 converts PCM to DSD (including 176.4 kS/s to DSD) using the
arrangement given below:
arrangement given below:
do this:
Connect any digital audio source of any wordlength between 8 and 24 bits,
using single, Dual or Quad AES to the AES inputs, or using single or double
speed SDIF-2 to the SDIF-2 inputs, or using single wire SPDIF to the
appropriate SPDIF input, and select the input accordingly.
using single, Dual or Quad AES to the AES inputs, or using single or double
speed SDIF-2 to the SDIF-2 inputs, or using single wire SPDIF to the
appropriate SPDIF input, and select the input accordingly.
do this:
Set
Output Mode
to
DSD SDIF-2 or DSD SDIF-3
. Choose a
Filter
if you wish.
do this:
Output SDIF-2 via the
DSD/SDIF
connectors, two data cables and one word
clock or SDIF-3 with just two data cables.
do this:
Alternatively, take the DSD Quad output from the
AES 1
,
2
,
3
and
4
outputs.
