Do you have a troublesome microphone? Or do you just want to make sure that you won’t have feedback problems throughout your program. Whatever your scenario, I am going to show you how to ring out a microphone in order to make it more stable.

First off, make sure there isn’t anyone around the mic. If there is, kindly tell them, “heads up, it’s about to look like I don’t know what I’m doing!”

Step 1 

Assuming you are already plugged into the system, leave the mic on where it is intended to be used. Bring your fader to unity and slowly and CAREFULLY turn gain up until you start to hear some atrocious frequencies, thats the first part!

Step 2 Figuring out what that frequency is

Make sure you don’t take your hand off of that fader or gain pot without turning one of them down. If you can identify the offending frequency, good for you! Now get to EQ’ing! If you aren’t as familiar with frequencies, there are apps that you can train with and use to identify frequencies that are feeding back. Tone Gen Pro is one example. Another way you can do this is if you have an RTA handy. Real time analyzers will display what frequencies are acting up! Be sure to not cut too much out of these frequencies as tonal changes will occur as well. Just enough to take the feedback out. If you find that you are sacrificing too much tone. At least you know which frequency will take off first. That is valuable information! Get your EQ dialed to that number and in the case of feedback all you have to do is reach up and turn it down.

Step 3 Keep Digging

You will probably notice how much more stable the mic is now (pretty cool huh?) If you would like to keep going be my guest, just follow steps 1 and 2 again. You may get the double whammy feedback going on. Just do your best and you should end up with microphones less prone to feedback.
