Figure 9 – General Sample Rate Conversion
The dCS 974 converts any one of 12 sample rates in any format to any of the 12
sample rates in ALL formats: 4 AES, 2 electrical SPDIF, optical SPDIF or
SDIF-2 outputs. Most frequency combinations (including all the primary ones)
are accommodated in one pass - see Table 2 on page 44. For best results,
slave the unit to the audio input, AES Ref Loop In or the SDIF-2 WCLK IN.
do this: Connect any digital audio source of any word length between 8 and 24 bits,
using single AES or dual AES 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.
do this: Select Audio Input accordingly. Output via any of the outputs.
Sample Rate Conversion settings:
Sample Rate Conversion: On
Audio Input Select: Any, including Dual AES if the Input Sample
Rate is 88.2kS/s or more and Quad AES if the
Input Sample Rate is 176.4 kS/s
3
or 192kS/s.
Output Mode: Normal or Dual AES may be selected if the
Output Sample Rate is 88.2 kS/s or 96kS/s.
Dual AES or Quad AES must be used for
192 kS/s or 176.4 kS/s.
Other settings: Any.
3
It has to be Dual AES or Quad AES for 192 kS/s or 176.4 kS/s
