Pre-/post-setting
Sending pre-processed master bus signals to matrix channels reduces the overall
system latency. If post-processed tap-o 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-o points produces a system
latency of 2.44 ms, as opposed to pre-processing tap-o points, which would
produce a latency of 2.26 ms. When Monitor Mode (Align with Masters) is
switched on, these values are 1.83 ms and 2.01 ms, respectively.

Typical congurations
The following subsections contain actual examples of typical congurations to
illustrate the eects of delay compensation. Please note the following:
• All XLRs are located at stage end, unless FOH is stated.
• INS can mean an internal eect or an external eect with analogue or AES3
I/O at either FOH or stage positions.
• Abbreviations are: IP = input channel; AS = aux (send) channel, AR = (aux)
return channel; AR (Input) = (aux) return channel set to input mode; MAST
= master channel; MTX = matrix channel; DI (Mix) = direct input set to Mix
Time Zone (DI can be either pre- or post-); and DI (Input) direct input set to
System Input Time Zone (DI can be either pre- or post-).

Master to matrix post-processing option
The signal path that feeds master bus signals onto matrix channels is fully
compensated for, so that signals fed directly to matrix channels or indirectly to
matrix channels via master channels will always line up at the outputs, as will
signals sent only to masters or only to matrix channels.
You have a choice of tap-o point, so you can choose to send either a pre-master
or post-master channel processed signal to the matrix channels. This is a global
setting and aects all master -> matrix contributions (see Table 30 “Master and
matrix tap-o points”).
