Digital Sample Rate
Hz
DFS sample rate for digital input signal.
Recommended values are: 32 kHz,
44.1 kHz, or 48 kHz. Over-sampling rate
must be set in order to satisfy a minimum
DCLK of 1 MHz. Sample rate must be set to
0 before DCLK/DFS is removed.

Hi-Cut Attack Rate
Set the rate at which hi-cut lowers the cutoff
frequency. If set to 0, hi-cut attack is
disabled.
