GROUP DELAY (LATENCY):
Delay from digital input to analog output is a function of sample rate:
2.72 ms at 28 kHz
2.51 ms at 32 kHz
2.10 ms at 44.1 kHz
2.01 ms at 48 kHz
1.55 ms at 88.2 kHz
1.51 ms at 96 kHz
1.28 ms at 176.4 kHz
1.26 ms at 192 kHz
The delay can be calculated using the following formula:
Delay = 1.01 ms + (48/Fs)
Where Fs = the sample rate in Hz.
