D21m System
5.5 Input/Output delays
Different DSP core types as well as the different I/O cards cause different
delays. Several facts require additional consideration. Total I/O delay is the
sum of the delays given in the tables below and depends on the configuration.

Enabled input and output SRCs each cause an additional delay, depending on
input and output sampling rates – for details refer to chapter 5.5.1 .
** Local MADI, ADAT, and TDIF interfaces have approximately the same delay
as the AES/EBU interface (±1-2 samples)
