Group Delay (Latency)
Delay – Digital Input to Analog Output (function of
sample rate)
The delay can be calculated using the following formula:
Delay = 1.01 ms + (48/Fs)
Where Fs = the sample rate in Hz.
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
