Stop feedback once and for all with the DFN-800 Feedback Reducer. The DFN-800 by ImPro is an automatic feedback reducer that helps stop the loud and noisy feedback sound from your system. It is specifically created to help stop the loud screeching sound that microphones make. Feedback is caused when microphone sound is amplified over and over through a speaker system, causing a high-pitched noise. Just plug and use with any microphone system and sound system.
