256 Chapter 28: Delay Compensation (Latency)
PRO Series Live Audio Systems
Owner’s Manual
Monitor Mode (Align with Masters)
The default control centre bus structure is organised such that inputs can be routed to
masters and also simultaneously routed to masters and matrix channels via the aux
(aux send) buses (Figure 28) or via the aux and return buses (Figure 27), while
maintaining the same overall input to output latency in both paths.
This may not be the desired structure if aux (aux send) and matrix outputs are both
being used for monitor mixes, where it is desirable for aux, masters and matrix outputs
to be time-aligned with the minimum possible latency.
When this switch is on, the delay element that is used to delay the paths from input
channels to master/matrix channels is removed. With all insert and GEQ delay
compensation switched off, the latency between a system input XLR and a system
output XLR being fed by an aux, master or matrix channel is 1.83ms (Figure 29).
In this mode, it is advisable to use the same GEQ and insert compensation settings for
aux and master/matrix channels to maintain their identical output latency.
