Since Sabine first invented digital feedback control in 1991, FBX Feedback Exterminators have set the standard for transparent and reliable automatic feedback control. Now Sabine is proud to announce the next generation of automatic feedback controllers: The FBX1200 and FBX2400, now with SMARTFilter™ Technology.

THE POWER OF FBX

The power of the FBX with SMARTFilters lies in its ability to control feedback during the program, not just at setup time. If feedback occurs during that crucial moment of the show, in the middle of the big solo, or just when the worship leader begins the sermon, the FBX places a filter that only kills the feedback, not the sound and power you work so hard to achieve.

Think of the FBX as a very advanced set of automatic parametric filters. If you had the time, the filters, and the test equipment, you could find the feedback frequencies, dial in the precise filter location, and make a very narrow filter, just deep enough to remove the offending tone. The FBX does it all for you auto-matically, and it does it faster than any other method.

How do we do it? First let’s consider just how a superior feedback control filter should behave. Filters can be described by their Speed, Accuracy, Resolution, and Sonic Integrity.

SPEED

The industry’s best digital signal processors that run the SMARTFilter algorithm give the new FBX1200 and 2400 a distinct speed advantage over all other automatic feedback controllers. And in Setup Mode the speed is increased, so you can complete your entire setup of the FBX in less than 30 seconds. During the show the 24-bit FBX is constantly on the watch for feedback, never allosing it to ruin your show. Filters are placed almost immediately (in 0.4 seconds at 1 KHz.)

ACCURACY

Is it music or is it feedback? This is the most difficult question your feedback controller must answer. A wrong decision means you waste filters (less gain for you) and punch unnecessary holes in your sound. The FBX has always excelled in its ability to make the right decision, and the new SMARTFilter technology makes it even better.
Less sophisticated feedback controllers place filters on any loud tone, even if it is music, but the FBX uses a patented analysis of the harmonic content of your program material. Because feedback is low in harmonics, and music and speech are rich in harmonics, the FBX is able to make the correct and accurate answer to the music or feedback question.
