changes to the current filters status.

Manual AFS 2 Set-up in FIXED mode (Ringing Out The System)
1) Make sure all filters are cleared and set the AFS 2 process to Bypass using the blue bypass button.
2) Perform a sound check and set up a rough mix for all microphones that will be active during the
performance. Take note of the output fader position for the aux master or stereo master that you are ringing out – your
TARGET GAIN will be around 5dB above this (see step 6).
3) If noise gates are being used on active mics – including inside FX processors, bypass them before
ringing out the system. You can re-enable them once the ring-out procedure is complete.
4) Have the musicians stop playing and fully lower the master bus faders. NOTE: When ringing out the system in
Fixed Mode, any sustained sound detected by AFS 2 will trigger Fixed filters to be set. Therefore, make sure the micro-
phones are active, but there is no appreciable signal present at the mics.
5) Ensure the musicians are not playing, then set the FILTER MODE parameter to FIXED.
6) Un-bypass the AFS 2 process then slowly raise the master fader until you reach your target gain
(described in step 2) or run out of Fixed Mode filters, whichever happens first.
7) Lower the Master bus fader back to performance level.
8) Set the FILTER MODE parameter to LIVE. The system is now ready for use and any available Live filters will be
available for on-the-fly feedback suppression during the performance.
