Description
The feedback suppressor was originally designed to eliminate feedback. It uses the latest DSP technology in order to efficiently and frequently shift the audio signal. This system is widely used in commercial buildings, plazas, schools, karaoke, meeting rooms and other places. Each microphone channel has an independent phantom power switch, which effectively protects both the speaker and other audio equipment.
