In the middle of the far e launched FBX2420 feedback suppressor new!

Shanghai dynasty Electronics Co., Ltd was established in 2005, the agent Sony, iron triangle, dahua, Polycom's four brands. 2007 comprehensive launch SEEKFAR (middle distance) Conference discuss the system, front end session related equipment and information publication system. 2008 SEEKFAR (middle distance) brand full year sales growth of more than 200%. Just four years, rapid development, recently introduced a SMART Filter technology FBX2420 feedback suppressor new products. First, use the feedback suppressor FBX2420 SMART Filter technology of the FBX skill in during the show, not the system adjustment period control feedback. If you are a very important show moments, large single chip in the middle of the performance or just in the distinguished leadership feedback occurs when starting speech to an inhibitory feedback filter quietly adjusting to feedback frequency is very difficult. Thanks very much FBX as an advanced automatic parameter adjustment device, its test devices and filters can automatically search for feedback frequencies and precisely adjust filter position, establish a bandwidth very narrow, absorption depth sufficient filter to automatically eliminate worry of squealing voice. FBX is automatically adjusted to the speed of adjustment than any other way faster. How? first thing to consider is the quality of feedback control filter. Filter quality which you can use the adjust speed, accuracy, resolution, and the consistency of the sound. Speed: in the new FBX 2420 SMART Filter runs in the algorithms of the digital signal processor speed advantages over all other automatic feedback controller, improves the speed of the system adjustment, in less than 30 seconds of time in the various parameters of the FBX automatically adjust. During the performance, the FBX 24bit will continuously monitor feedback will never allow it, undermine the performances. Filter almost can be set immediately (kHz in 0.4 seconds). Eliminate feedback speed feedback signal amplitude available decay time for instructions. The above chart illustrates the Elimination of competitors, note that feedback speed diagram eliminate feedback response time is longer. The following figure illustrates the FBX faster time to eliminate feedback. Accuracy: is the music signal or feedback signal? this is the most difficult to answer feedback controllers. Bad judgement means wasting filter (reduce system gain) and produce unnecessary "gu" sound holes. FBX outstanding performance is always accurate judgment. New SMART Filter technology to make it more effective. No complex feedback controllers to filter on some big sound, even the music program. However, the use of patented technology FBX can analysis program of harmonic components, because of the harmonic components of feedback is low, but music and language program contains rich harmonic components, so you can correctly answer the FBX is music or feedback. Resolution: this is a big problem, now we know that feedback is a fortuitous event, we need to accurately target it. A lot of feedback controllers to filter General moved to feedback frequency of nearby, and relies on increasing the bandwidth of a filter, eliminate feedback. FBX takes a more complex solution. It filters the center frequency precision tuned to feedback frequency. This unique 1Hz resolution to FBX with 1/3 octaves narrow bandwidth graphic equalizer 10 x the very narrow bandwidth filter control feedback. Feedback frequency is a tone frequency, means that in the audio spectrum range almost 20000 position feedback can occur. You can see the use of a low resolution feedback controller is like using a shotgun shooting in flight, you may eventually be shot down, but you need to consume more bullets, and can cause a lot of damage. Obviously, FBX 2420 1Hz resolution used to precisely select filter position, meaning that every time it can tone feedback frequency directly. Filter quality: the real value of the constant-Q filters in any absorption depth can maintain-3dB bandwidth of constant power point. Sabine used the most rigorous primary method to calculate the bandwidth of a filter. The sound of consistency: Sabine on digital filter innovation process is unique in the industry, providing digital filter number exactly the sound better, with smaller phase distortion and smooth frequency response. Sabine filter in all of the sound absorption depth to maintain consistency, providing true constant Q values of characteristics.
