This example shows the 4 groups, L, R, and
Mono outputs feeding a 7 stack FOH amplifica-
tion system. The groups provide independent
control of the additional left and right loud-
speaker stacks, or may be used for separate
effects or zone feeds, or for subgrouping to the
L-R mix.
Select aux 1 to 4 post-fade to access 4 effects
processing devices. Use Return inputs 1 to 4 to
add the effects to the L-Mono-R outputs. Alter-
natively use the stereo or mono channels to mix
the effects into the groups and foldback as well.
Select aux 5 and 6 pre-fade for 2 foldback
monitor sends.
The channel and output inserts may be used for
floating effects and signal processing devices
such as compressors, limiters and graphic equal-
isers.
