Feedback Suppressor NVS-70020002FS

The NVS-70020002FS is an advanced digital feedback suppressor that offers excellent performance at a competitive price. It allows you to store 10 sets of data for controlling tone quality in different situations. During the feedback suppression process, it can reduce the feedback signal by up to -48dB. When feedback is detected, the device swifly and automatically analyses and locks the feedback frequency using its advanced DSP algorithm. It determines the frequency point, frequency bandwidth, and attenuation of the notching filter, and saves the processing results. By controlling the frequency bandwidth of the notching filter, the device filters out only the feedback signal, preserving the music signal without compromising its quality, resulting in exceptional audio fidelity.
