WL747A Feedback Suppressor

INTRODUCTION

A Feedback Suppressor is a crucial device used in sound reinforcement systems to prevent audio feedback, which occurs when a sound loop is created between a microphone or an instrument and a speaker, resulting in a loud and high-pitched tone.Feedback can be a significant problem in live sound applications and can be difficult to control without the use of a feedback suppressor.
