Feedback Suppressor

This is feedback suppressor originally designed to eliminate feedback. It uses the latest DSP technology to very efficiently frequency shift the audio signal. This system is widely used in commercial buildings, plazas, schools, Karaoke, meeting room and other places. Each microphone channel has phantom power switch independently. It can protect the speaker and other audio equipment effectively.
