How to Ring Out Your Mics - #AscensionTechTuesday - EP024

hey hey I want to know tech tuesdays is chad from ascension worship this week i'm going to teach you the age-old technique of wringing out your microphones hey what do you say yes it's a time again his tech Tuesday so if you've done any live sound at all you're probably familiar with a hot mic and by that I mean a microphone that is picking up a lot of things like say a pastor's headset microphone and because it picks up so much it can cause feedback easily so what we're gonna do today is is teach you how to ring out a microphone so I've got hopefully you can see this in the camera I've got a standard shure sm58 and i'm in very close proximity to a studio model that's pointing right at the back of the mic so what we're going to do today is I'm going to get the microphone as loud as it can go without feedback and then I'm going to EQ the feedback frequencies out so how I'm gonna do that is I'm going to go to my channel EQ of which I've got four bands of EQ to work with and I'm going to slowly raise up the EQ and move it around until I find the frequencies that cause feedback and as I go I'm going to flatten it back out and then I go to a 31 band EQ that's working in the background and take those frequencies out of the mic so that I can get the microphone louder without running into feedback so I'm very surgically cutting out the the problem frequencies doing this now one thing I'm going to do today to make sure that that your ears don't explode and more importantly Meier's don't explode is I will have a really strong compressor on the microphone so that as I get feedback that will kind of keep it from getting out of control this is a really good idea if you're doing this in a in a large sound system so that people still love you at the end of the day so let's get into it and see what we can do all right so we've got my microphone here and I'm going to place it turn it up and see how loud I can get it before we start getting feedback check one two one two one two hey one two there we go swing a little bit feedback okay one two one two one two so I can get to about negative ten on my fader before it's starting to sound a little bit unstable so that's going to be kind of our starting point I'm gonna get us up to negative ten maybe a little bit higher than that and and then kind of cause some feedback intentionally using my channel EQ and then again go to my thirty-one band EQ and take that out so let's turn it up just one one there we go alright looking at my channel EQ I'm going to turn that up so looking at the EQ that just did on here I can see that that's about 138 Hertz so I'm going to go to my thirty-one band EQ and find whatever frequencies are closest to that line cut out and again I'm going to try and induce that feedback so I know exactly what I'm turning down and then turn this frequencies down so here we go let's find 138 here's 125 160 so 125 is closest so I'm going to cut that down let's keep you want to hear some some high-end hits let's try and find that so there's one around 900 so 1k is real close let's take that out you can also if you have an EQ like this you can see on here it's giving us a graphical representation of where so the frequencies are with that's also very helpful so we can look on here is another alternative so we have something around 6 6k and 300 Hertz to 8k somewhere in there so let's go over there another thing I tend to do is if I cut a fricassee if it's really close to the next surrogacy down I will get a little cut there I find that it sounds more natural than just scooping out of nowhere so if you kind of create like a little curve almost of what you're doing that seems to sound pretty good skipping around trying to find what's causing the feedback we're looking pretty good there's one little more 150 little more around 1k somewhere in there 1k tends to be a problem a lot of times I'm going to turn the fader up some more see how much more we can get out of this before we're done there's one around 8k see a little more of that here there's something there around 4k I'm slowly turning the mic up some more thrown 360 well it's only around 200 we're looking pretty good little around 570 600 somewhere in there till something the low 300s 2k see a little bit more around that 2k out 4k 7k 12k and then just for good measure this is for a vocal mic imagining this is for a pastor's headset we probably would not need anything up to 100 Hertz so let's just go ahead and just cut all that out just to keep it safe so now we've gone from where we couldn't get a stable mic from from about negative 10 I now have the fader at zero and I'm not hearing any any resonance so it's not until about a positive five then we're starting to hear to get unstable again so we just freed ourselves up about 15 DB of extra gain so let's just say quick listen to hear out sounds one-to-one sorry let me turn my compressor off one two one two one two one two that sounds pretty good so here is I'm going to turn I'm not gonna go all the way up because this is good to feedback but I'm going to now turn that compat EQ off so we can kind of hear what's happening so here's what's it on OOP here's it native five on/off one two one two and in here that it's about the feedback at any moment back on one two one two and turn the fader up a bit one two so you will notice there is a little bit of loss of gain which makes sense because we've been cutting out Francie's but now that you've got this set the way you want you can use your channel EQ which if you look on here is effectively completely flat you can use your channel EQ to create the tone that you want for the person's voice for example if a female voice where to come up right now and you would add a little bit more bottom end into it to kind of fill it out you can do that and use your your channel EQ for tone because your thirty-one band EQ is doing all the the noise reduction for feedback so just be careful that you don't over do this and make things sound completely unnatural the best thing to do is to do like we did and sculpt everything away and then slowly once you feel how loud you can actually the mic maybe put some experiencies back in if it sounds a little bit robotic and unnatural again this is chad from ascension worship i hope this has been helpful for you and your team come back here every Tuesday for new information
