How to Stop Microphone Feedback When You Sing Karaoke

Needed Tricks to Stop Feedback

Using the microphone right is key to stop feedback when you sing karaoke. Hold the microphone 4-6 inches from your mouth at a 45-degree angle, and never hold the microphone head as this makes points where sound can bounce back. When feedback happens, step back 2-3 feet from the speakers and stand toward center stage.

Fast Ways to Control Feedback

• Turn down the main volume by 3dB
• Cut monitor levels by 25%
• Stand right on stage
• Stay behind floor monitors
• Keep at least 3 feet away from speakers

Better Ways to Stand

• Standing behind floor monitors
• Always keeping the same space from main speakers
• Avoiding a straight line with speakers
• Moving toward center stage when feedback happens
• Changing the microphone angle based on how the room sounds

Know the Basics of Microphone Feedback

Audio feedback happens when live sound setups make unwanted loops between a microphone and speakers. This sound problem happens when a microphone hears its own loud output from nearby speakers, making a loop that gives off a high-pitched noise known to most.

Types of Feedback

Low Noise Feedback

Low noise feedback shows up as a deep rumble before the main sharp noise. This early sign shows possible system trouble and needs fast care to stop a bigger mess.

Big Noise Feedback

Big noise feedback makes a loud, long noise that can hurt sound tools, hurt the hearing of people listening, mess up a show, and make sound bad.

Put Your Microphone the Right Way

Putting microphones right is the core of stopping sound feedback during live sound boosts. Keep a 45-degree angle between the microphone front and your mouth, always keeping a 4-6 inch space.

Change Sound System Settings

Getting your sound system right starts with exact control of tone reply. Look at the key range between 250Hz and 4kHz where most feedback problems happen. Cut problem tones by 3-6dB to set a stable sound base and stop unwanted ring.

Pick the Right Tools

Dynamic microphones are the main part of feedback-free sound boosts. The Shure SM58 and Sennheiser e835 are much better at stopping feedback. Cardioid sound paths are great at cutting unwanted sound pick-up, mostly from speaker spots behind the microphone.

Know the Room Setup

Looking at room sound is key to stop microphone feedback in any sound spot. Start by looking at key sound parts like room size and surface stuff. Shiny surfaces like glass, tile, and metal need extra care because they bounce sound.

Fast Fixes During Shows

When unwanted sound feedback messes up your live show, act fast. Put the microphone right as your first move against feedback. Keep the right space by moving a few steps from nearby speakers and angle your microphone well. Use inline volume control to cut microphone sensitivity fast.

Best Ways for Sound Checks

Getting the sound check right is basic for stopping microphone feedback. The smart placing of microphones needs keeping at least 3 feet from main speakers. Use a 31-band equalizer to look at and handle problem tones in the key 250Hz to 8kHz space.
