Input Sample Rate

Output Sample Rate

Output Sample Rate is a parameter for PCM output modes only. Select the required Output Sample Rate from the list and press Set. The dCS 974 accepts 112 input / output sample rate combinations (including DSD) in one pass. The remaining 70 combinations can be accommodated in 2 passes. These are shown in Table 2 overleaf.

Not all the apparently valid output sample rates may be available to you from
