AFS2isadbxfeedbacksuppressionsystemthatuses12intelligentlterstodetectandeliminate
feedback across the audio spectrum. You can set AFS2 up on the master stereo output and/or Aux bus
masterchannelsbynavigatingtothechannel’sEditscreenandselectingtheEQtab.
AFS

works in two modes. Fixed modeisusedfor‘ringingout’asystembefore a performance to ensure
maximum headroom. Live Mode,continuouslyupdateslterplacementandisusedduring a performance.
LiveltersaresmarterthanFixedlters.Theyhavetheabilitytodetectfeedbackwithincomplexprogram
material. This makes them ideal for protecting the system from feedback as conditions change during the
performance.Livelterscanalsodetectwhentheyarenolongerneededandremovethemselvesfromthe
chain,effectivelyrestoringsonicdelityandfreeingupLiveltersforuseelsewhere.
In normal operation, you would setup AFS

in Fixed mode before a performance, then switch to Live mode
for the actual performance.
Ringing Out The Sound System
Fixedltersaresetbeforeaperformanceinaprocesscalled‘ringingoutasystem’.Thisisdoneafterall
other system EQ has been performed. Ringing out the sound system for feedback before use allows you to
squeezemoregainoutofthesystembeforetheonsetoffeedbackandcanhelpensureyou’renotrightat
the edge of feedback during system use.
