Monitor Mode (Align with Masters)

The default console bus structure is organised such that inputs can be routed to
masters, and also simultaneously routed to masters and matrix channels via aux buses
(see Figure 19 "Routing via aux buses") or via aux and return buses (see Figure 18
"Routing via aux and return buses"), while maintaining the same overall input to output
latency in both paths.
This may not be the desired structure if auxes and matrix outputs are both being used
for monitor mixes, where it is desirable for auxes, masters and matrix outputs to be
time-aligned with the minimum possible latency.
With this option switched off, 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 is being fed by an aux, master or matrix channel is 1.79ms (see Figure 20
"Latency for input to aux, master and matrix outputs").
If using this option, it is advisable to use the same GEQ and insert compensation
settings for aux and master/matrix channels to maintain their identical output latency.
Monitor Mode = OFF, Aux Send & Return Compensation = ON, all other compensation = OFF
Aux Bus Alignment = ON, Aux Send & Return Compensation = ON, all other compensation = OFF
