Fully functional interface: 6channel input mapped to 6channel output with a durable metal snapon interface. XLR connections provide a stable signal. Advanced feedback suppression: professional automatic feedback suppression algorithm with memory for 8 howl points, delivering effective antihowl action and better protection for power amplifiers and speakers. performance digital processing: a configuration digital processing chip automatically identifies the audio signal, suppresses feedback noise comprehensively, prevents howling, and improves overall sound quality. 5stage parametric EQ and digital frequencyshift antihowl: internal circuitry uses 5stage parametric equalization and digital frequencyshift antihowl technology to extend microphone recording distance and reduce howling noise, achieving up to 99% antihowl effectiveness. 23 practical use scenarios: Live sound reinforcement in small to medium venues, ensuring clear dialogue and music without feedback. Conference rooms, meeting spaces, and lecture halls where stable, clean sound is essential for presentations. Recording or rehearsal environments, including home studios and podcast setups, where reduced feedback and improved sound quality are important.
