Use this configuration to independently protect
two single microphones from feedback, while
leaving all other audio channels unaffected.
Use this configuration to protect two independent
groups of microphones from feedback, while
leaving all other audio channels unaffected.
Use this configuration to protect the entire system
from feedback. Your mixer must have master
insert connections to use this configuration. This
places the AFS2 before the master fader so that
it can work optimally no matter where the master
fader is set. If you have a system EQ, you can
place it before or after the AFS2 in the chain.
Use this configuration to protect the entire system
from feedback when your mixer doesn’t have
master insert connections. If you have a system
EQ, you can place it before or after the AFS2 in
the chain.
