The AFS Advanced Feedback Suppression processor was designed to provide state-of-the- art feedback elimination processing, while maintaining a simple and intuitive control interface. From the powerful DSP module to the no-nonsense user interface, the AFS provides all the processing and control necessary for both installation and live use. The AFS is an absolute must for any live sound application. Ten and twelve filter feedback elimination processors have become the de facto standard, but the engineering staff at dbx have never been content residing in the neighborhood of the sta- tus quo. To achieve these staggering numbers dbx utilized their patent-pending AFS technol- ogy that had previously only been available in the upper echelon line of products and made it available in this stand-alone processor. In addition to the plethora of feedback suppression filters available, the AFS also offers selectable modes, live filter lift, and types of filtration, which are all readily available via the intuitive user interface front panel.

The Mode buttons should be lit a yellow or amber color. If they are not press each MODE button until they are both yellow.
Page 3 Select how many total filters that you want active. The default of 24 is a good place to start. Hold this button until the filter LEDs flash all the way across. Press and hold the channel 1 TYPE button to select between dual mono or stereo mode. Page 6 Perform a sound check on all of the microphones that will be active.
Get them as close to the performance level as possible without feedback. Page 7 Pull the master faders on the mixer all the way down no signal. Check the Mode buttons. If they are not lit green, press the buttons until they are lit green. None of the filter LEDs should be lit at this point.
Slowly raise the master faders on the mixer. As feedback occurs, Fixed filters will be set. You may want to push the faders a little past the unity gain point or performance level. This way the system will not be right on the verge of feedback when set to performance level. Page 9 When you have reached the desired performance level, press the MODE buttons until they are both lit red. If, for whatever reason, you would like to restart the process, you can do so by clearing the filters and restarting with step 1.
Hold this button until the filter LEDs flash all the way across from the outside inward.

Dbx Advanced Feedback Suppression AFS224 Quick Start Manual
I remember when automatic feedback suppressors first appeared and were hailed by some, including me as a wonder of their age. Imagine having an invisible, unpaid extra pair of ears and hands constantly monitoring the PA for feedback problems and instantly applying selective EQ corrections as necessary, all without interrupting the performance or affecting the overall sound quality It all sounded too good to be true at the time, but it actually worked pretty well in many applications, and the detection algorithms have now evolved and become increasingly sophisticated The new Dbx AFS2 updates and replaces the well—established and successful AFS, which has been around for a few years now. As a user of the previous model myself I was interested to have a look at its replacement in the product line. I like to have a feedback processor available for every job I do, in the same way as I like to have extra sets of batteries and every kind of mains power adaptor — I may not use them every time, or even all that often, but every so often a situation will arise where that extra capability can make all the difference between a horrendous, stress—filled experience and a successful result. Much has been, and will continue to be, written about the reasons for and against using feedback processors, but I have always regarded them simply as automatic outboard EQ designed with a particular task — the control of feedback — in mind. With the AFS2 the team at Dbx have essentially taken the existing functionality of the AFS processor and developed new detection and control algorithms, along with an enhanced degree of user control and the ability to save and recall settings.
