Feedback Suppressor
Feedback Suppressor
NVS-70020002FSNVS-70020002FS is a digital automatic feedback suppressor with high performance price ratio. The device allows storage of 10 groups of data for needs of tone quality control in 10 different scenarios. During suppression process the attenuation range may be as low as -48dB. When feedback is detected, the local device will quickly and automatically analyse and lock the feedback frequency by using its advanced DSP algorithm and determine the frequency point, frequency bandwidth and attenuation of the notching filter, and will save the processing results. Since the device is able to control the frequency bandwidth of notching filter,only feedback signal is filtered, without damages to the music signal and with very high acoustic fidelity.
