These filters, once populated or FIXED, will stay at the set frequency and level. LIVE “L” filters will 
change as needed during a performance.

Turn the Data Wheel to choose the EQ notch filter width appropriate for your needs.  Speech is a wide

With the channel faders down, set the mixer’s master level to zero (0 dB). With the microphones you’ll 
be using during the performance in place and connected, turn up microphone channel levels until feed-
back begins. The AFS will start to populate the Advanced Feedback Suppression fixed filters.  

 

NOTE: Do not talk into any of the microphones or play music. This is only a search for feedback at this 

point.
