Our advanced computer algorithm automatically identifies and suppresses microphone feedback so you can concentrate on running the mix. Just raise the levels on your mics to the onset of feedback. The filters automatically "learn" the problem spots in your system and knock them down with great precision leaving everything else untouched for maximum fidelity. Then during the performance additional filters are constantly standing by to instantly kill any extra, unexpected feedback. Features: Dynamically suppresses feedback using sophisticated "search & destroy" filters, 16 individual filters can operate simultaneously (8 dynamically react to input changes), Stereo or "dual mono" operation which enables 32 dynamically-controlled filters, Set-and-Forget operation in fixed installations, Four presets for your most common performance venues, Rear panel Defeat button locks out inquiring fingers, Extra Max "Panic" filters for quick control of sudden, severe feedback, Balanced XLR and balanced/unbalanced 1/4" TRS inputs and outputs.
