Dealing with feedback in your audio setup can be a real headache, but the good news is that with the right tools—like limiters and EQ—you can clean things up fast. EQ helps you zero in on those pesky frequencies causing the squeal, while limiters keep your volume in check to avoid sudden spikes. Together, they’re like your dynamic duo for keeping sound smooth and feedback-free!
Using a Limiter
Set the Limit: Adjust the limiter so it catches loud spikes in sound (which can cause feedback) but doesn't affect the overall sound quality.
Attack and Release Times: Set it to respond quickly to sudden loud sounds and ease off gradually to keep the sound smooth.
Ratio: Use a mild setting (like 4:1) so it controls the volume without making the sound too compressed.
Using EQ (Equalizer)
Find Problem Frequencies: Use the EQ to search for specific frequencies causing feedback.
Lower, Don't Raise: Lower the volume of those problem frequencies instead of raising others.
Cut Low Rumbles: Use a filter to remove very low sounds (rumble) that might add to the feedback.
Monitor Placement
Position Speakers Carefully: Place speakers in ways that reduce the chance of feedback, such as directly behind certain microphones that naturally block some sounds.
Extra Tips
Microphone Positioning: Keep mics close to the sound source and avoid aiming them at speakers.
Volume Control: Keep speaker volume low enough for performers to hear but not too loud.
Watch for Echoes: Be careful with sound reflecting off walls or other surfaces, as it can bounce back into the microphones and cause feedback.
