Sabine FBX2400 24 Bit Stereo Feedback Eliminator Sabine FBX2400 Feedback Exterminators
Now with SMARTFilter technology
Since inventing the first digital automatic feedback controller in 1991, Sabine has always been acknowledged as the leader in this technology. The FBX2400 extends their edge with the introduction of new SMARTFilters. Now feedback control is faster, quieter and more transparent than ever before.
SMARTFilters have laser-like accuracy and resolution, targeting feedback while leaving your sound untouched. That means the FBX is the right choice when you want to control feedback during the show, not just at setup time.
New Three-Color Display: Setting up your FBX is easier than ever. The front-panel filter LEDs now show in three colors. Unlocked Fixed filters are amber, Locked Fixed filters are red and Dynamic filers display as green. You always know the state of each filter and where you are in the setup process.
Quick & Quiet Setup: Just push the Setup button and raise the gain – you’ll be ready to start the show in just 30 seconds. During setup the speed of the SMARTFilters is ramped up – you’ll be amazed at how fast you will be ready to go.
Transparent Sound - Better Specs: With 24-bit digital conversion and processing, the FBX1200 and FBX2400 sound great, and even better, they leave your sound alone.
Flexible Filter Control: Mix filter widths according to your application, lock or unlock your fixed filters, and reset your dynamics either manually or with the new Dynamic Filter Release Timer.
Pro Connections: Choose XLR or 1/4 inch balanced inputs and outputs, with gain switches on each input and output.
New Low Price: You can now get the best algorithm, the best features, and the best specs at Sabine’s most competitive price ever. And the new FBX1200 and FBX2400 are made in the USA.

Of all the problems you can have with your audio system, nothing is more obvious or annoying to the audience than feedback. You do not need
Golden
Ears to know something is wrong. Thanks to the Sabine FBX Feedback Exterminator, this problem is solved. The FBX makes a significant improvement in your sound – it's a difference you can really hear. Quite simply the FBX gives you the single most important function of sound reinforcement: gain before feedback. And that gain comes with increased clarity and all the mobility you need for your wireless microphones...
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 automatically, and it does it faster than any other method.
How do they 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 allowing 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.
Resolution
This is a big one. Now that we know feedback is happening, we need to target it precisely. Many feedback controllers place their filters in the general vicinity of the feedback and then widen the filters until the feedback goes away. The FBX uses a more sophisticated solution. It centers the filter exactly on the frequency that is feeding back. This unique one-Hertz resolution enables the FBX to control feedback with transparent filters that are ten times narrower than graphic equalizer filters, which can only muster 31 spots to place their very wide filters. Feedback frequencies are single tones, and that means there can be almost 20,000 places for them to occur in the audio spectrum. You can see that using a feedback control device with less resolution is like shooting a fly with a shotgun. You may eventually get that fly, but it will take a lot of shooting and cause a lot of damage!
In contrast, the FBX 1200 and 2400 place these accurately chosen filters with on Hz resolution. this means a direct hit on a single feedback tone - every time.
Sonic Integrity
Sabine’s innovative approach to digital filtering is unique in the industry. Our filters just sound better, with far less phase distortion and a smoother response. Sabine filters maintain their integrity at all depths, providing true Constant Q performance.
Some competitors tout the benefits of more filters, but why add more filters than you need? The FBX processor could easily produce 50 filters if Sabine wanted them, but they would only degrade your sound. Sabine's experience proves that twelve feedback filters per channel is the right number. More filters just cut into the quality of your sound. Some competitors tout ever narrower filters. The FBX processor can easily produce filters that are 1/100 of an octave wide, but Sabine's experience taught them that filters narrower than 1/10 of an octave allow the feedback to return with very little provocation. Sabine filters are transparent to the ear and offer the ideal balance of width and protection against feedback under shifting conditions. Making them narrower ultimately degrades their performance, and Sabine won’t do it.
Bright Multi-Color Filter Display
After the super-fast setup is complete the bright blue LED on the Ready button clearly tells you the show can begin, and you’ve got all the extra gain you need. You have complete control of the mix between filter types (see the Fixed and Dynamic Filter box above), and the bright, three-color LED display shows you your filter status at all times – you can see it from across the room!
The Bottom Line
Even with all the improvements of SMARTFilters, and the improved specs and audio performance, perhaps the best news is that we lowered the price! And the FBX Feedback Exterminator is made in the USA.
FBX will let you hear your sound and nothing else!
