AFS

MODE
Choose LIVE, FIXED, or LOCK
Fixed mode is for pre-performance set-up, Live mode is for use during performance, and LOCK prevents
changes to the current filters status.
SENSITIVITY
Adjust the input level feeding the AFS
2
detector and make AFS
2
more or less prone to mark a
signal as feedback.
Setting this parameter high will allow AFS
2
to detect the feedback and notch it out more quickly. Conversely,
setting it low will cause AFS
2
to be a little more hesitant to set a filter on the feedback until it reaches a
higher level.
ON/OFF
Turn ON the AFS
2
process.
You must make sure AFS is switch ON to use the process.

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 AFS2
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.
AFS2 has a dedicated preset manager whereby users LOAD/SAVE/RENAME/DELETE AFS2 presets to connected
USB media.
To load/save/rename/delete AFS2 PRESETS:
- Go to any AUX or the MASTER EQ edit page
- Click/tap the AFS2 SETUP button
- Click/tap on the PRESETS button found in the middle of the AFS2 filter display modal
- Use the PRESETS manager to LOAD/SAVE/RENAME/DELETE AFS2 presets to connected USB media
