Feedback Suppressor FB1300

The professional audio feedback suppressor adopts the active anti-squealing technology to make the peak point of output and the peak point of feedback frequency different so as to greatly inhibit feedback. Five equalizer circuits with independent parameter can be used to sweep frequency and attenuate peak feedback frequency, further improving the overall gain of the system. Built-in band pass filter can effectively prevent the noise caused by low frequency or high frequency. Built-in automatic limiter can effectively prevent the squealing caused by excessive signal amplitude. It can increase microphone gain by 6 to 14DB and greatly increase the adapterization distance. Simply operated, with the functions of special digital display peak feedback frequency and parameters equalizer adjustment, frequency shift numerical control adjustment, AUX volume adjustment, etc.
