This machine uses a powerful DSP system, which can actively filter the howling sound that causes the signal to be returned, and eliminate it before the return, so that the original signal is not affected
Under normal use, the machine does not need to be debugged, and it takes about 10 seconds to automatically adapt to the acoustic environment. The entire system will gain an additional 6-12dB.

If the use environment is bad (after multiple whistling during system debugging), the sound quality is abnormal, please reduce the volume appropriately, and then press the quick calibration button of the machine, at this time, the noise of -6dB will be randomly generated for a few seconds to restore the sound quality normal.

This feedback suppressor also has a built-in automatic mixer for two microphone inputs. The automatic mixer in the Plena Feedback Suppressor will automatically drop. (With 48V condenser microphone power supply).
