FB1600 DIGLTAL FEEDBACK EXTERMINATOR

Application:

Description:

The feedback suppressor designed with DSP digital chip processing can quickly search for the howling frequency point processing where the microphone is located, so that the effective pickup distance of the microphone can be easily increased. The circuit technology has a wide frequency response, and the frequency response range can reach 20Hz-20KHz. The unique DSP digital data algorithm processes the microphone whistle, which suppresses the venue whistle to a greater extent and greatly improves the microphone due to the distance. Under the situation of using multiple microphones at the same time, it automatically detects the acoustic data of the venue environment, and can be used directly without debugging the equipment. The correction efficiency is high and the dynamic and significant sound quality is guaranteed.
