Figure 30: Master and matrix tap-off points
Sending pre-processed master bus signals to matrix channels reduces the overall
system latency. If post-processed tap-off points are used, the system must
compensate for both the latency of the matrix and master channels, and — if insert and
GEQ compensation are both required on master and matrix channels — this can push
the maximum system latency up to 10.1 ms. With no other insert or GEQ
compensation switched on, using post-processed tap-off points produces a system
latency of 2.44ms, as opposed to pre-processing tap-off points, which would produce a
latency of 2.26ms. When Monitor Mode (Align with Masters) is switched on, these
values are 1.83ms and 2.01ms, respectively.
