Sabine FBX2810

The new FBX-2220 dual-channel feedback suppressor 20-bit resolution 24 automatic filters (12 per channel) ClipGuard, professional design and automatic tracking clipping level, the gain and dynamic range was raised to 105dB system gain (gain before feedback ) 6 to 9dB enhance ease of operation, not two minutes to complete the set filter selectable 1/10 octave or 1/5 octave, constant-Q automatic tracking, feedback frequency what is the feedback it? Sound Feedback is emitted from the speaker to the microphone input back, through the amplifier, and came out from the speaker again, and made whistle, which is feedback. Feedback whistle solution is very simple, for example: to lower the volume, the microphone away from the speakers, which are commonly used method. Many times, the volume of the PA system is not up to full load can no longer increase, because the feedback appeared whistle. No matter how many sound reinforcement equipment margin, a critical value reaches this feedback, the volume can not be put up. This is what we call [system gain before feedback]. Old sound and stage design, usually placed behind the microphone speaker, feedback opportunity will be reduced, so that the volume can be raised without being limited by the feedback threshold. The new stage design, often will forward the stage (the audience) stretch, the singer will be the speaker position often before. Especially the popularity of wireless microphone use, the singer often went to the audience, his position is unpredictable in advance, therefore relatively easy opportunity for feedback. Retractable stage, karaoke OK place. . . Before are some very typical example, singer (microphone) will be in frequent speaker, slightly increase the volume, the system will whistle, and not enough volume and vice versa - you come across these problems? Feedback Destroyer you will be able to solve this problem. We usually only hear the shrill whistle, but do not know the howling occurs only in some of the frequency, and the frequency with room to build sound structures, microphone and speaker location and distance are somewhat related, but these frequencies are in drift. In addition to using feedback suppressor, experienced tuner can take advantage of 31-band graphic equalizer to reduce the opportunity for feedback, but he must be a "Thousand-hand Buddha" and "ears." Because the feedback frequency is constant drift, tuners must foresee feedback will occur before the whistle in the frequency and the attenuation. SABINE Sabine feedback suppressor company is to automate the above work, automatically detected by the machine, automatically find the frequency, amplitude attenuation is automatically adjusted, to ensure at the same time inhibit the whistle, do not destroy the original sound.
