24 bit / 96kS/s (or 192kS/s) Dual AES to DAC

Figure 8 – Upsampling a CD to 24/96 (or 24/192)

The dCS 974 converts a 44.1 kS/s 16 bit SPDIF input to a Dual AES 96 kS/s 24 bit signal available from AES 1 & AES 2 outputs. There is no information added in the process, although you may wish to check theory here.

do this: Connect a source of CD material to the RCA input on the dCS 974.

do this: Enter the Sample Rate Conversion settings below.

do this: Connect Dual AES data from both AES 1 and AES 2 outputs to a DAC of your choice.

do this: If your DAC is a dCS Elgar, dCS Delius or dCS 954, you can set the Output Sample Rate to 192kS/s instead.
