ClearOne SABINE FBX2410 Feedback Exterminator

Introducing the next generation in automatic feedback controllers: cleaner, faster, more transparent.

Since Sabine first invented digital automatic feedback control in 1991, FBX Feedback Exterminators have set the standard for transparent and reliable automatic feedback control. Sabine's latest product in automatic feedback controllers are FBX2410 Dual Channel Feedback Controller and the FBX1210 single Channel Feedback Controller. ClearOne continues to make these FBX units.

The FBX2410 includes the latest improvements to patented feedback control algorithms, providing the fastest ever feedback detection and elimination. It's one Hz placement accuracy means these filters are even more transparent, and the signal to noise ratio has been improved by 10dB. All this means the best just got better.

The Power of FBX
FBX Feedback Exterminators set themselves apart for their 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 automatically, 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 give the FBX2410 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.

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. 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.
