Do you ever hear a loud screeching noise coming from your speaker? That terrible noise is known as feedback! It is caused by a sound loop that is created between a microphone and a PA system. Feedback suppressors are used in live sound settings to prevent any screechy noises. These suppressors locate the frequency that is causing the feedback and use the EQ to make any necessary adjustments to make the feedback disappear. AVMaxx has exactly what you need to make your feedback disappear! Call now on our toll-free number for more info: 800-249-9450.
