I love how you use SMAART to visually point out these trouble frequencies and explain clearly each step that you are doing as you are doing it. I tend to keep use graphic EQs for outputs (FoH, Wedge) not inputs (mics) but I see whatchya doin! Definitely subscribing!

[@unacceptableone]

just getting back into sound. Love these new digital mixers. I used to bring the system up to the brink of feedback and then move across the GEQ boosting each freq. to find the hot ones, and then cut those..... this capability is way better!!!! channel PEQ for the win!!!! Thanks for this demo.

[@AttawayAudio]

You're welcome! Nothing like ringing out feedback with a room full of people (working, obvs.) AND doing a live video!

[@Jumpy66]

I‘ve a lot of methods to elevate feedback of choir Mic. You have a natural db limit. The most feedback come from Monitors 1. To get no choir mics to Monitor. 2. If it is possible you can work with In ear Monitoring. 3. Or you give Dynamic mics for the 4 Voice Soprano Alt, Tenor for the best singers to get only to the Monitor. 4. Look for the room, what is possible to Place the front. Eventually work with delay Lines. 5. Sometimes it is helpful to work with compressor. But you must have experience. 6. You can cross the Pan. Left Mics to Right Boxes. 7. To work with feedback eliminator. This is like make in the video manually. 8. Look to decorate the wall, and didn‘t have no hard walls. 9. Eventually work with Gate, to reduce the open mics. All this steps are first to to until you eliminate Feedback manually. The feedback Frequences changes with temperature. With people full room. Mostly it will be better. But you must have headroom of loudness. For Soundcheck in an empty Room, you must have 30% more loudness in a full people room. I‘ll hope with this tips you have a well concert. God bless you.

[@busterfoxx]

Thanks for the pointers. I hadn't thought of 6) "crossing the pans"... That makes a lot of sense.

Hey man this is very helpful. Just a quick question. Are you EQing the mic channel or the monitor channel?

[@MichaelNatrin]

Thanks for sharing! Great tips. I like that you explained what to do if you don't have the time to ring everything out.

[@AttawayAudio]

Hey that’s reality. You don’t always get all the time you need #realworld

[@jimpemberton]

One issue I ran across with our choir mics is that once each mic was rung out and I turned them all back on, I was getting feedback on frequencies that I had reduced on some of the mics. Our eight choir mics were acting as an array. (It's clear the architect of our worship center didn't know much about acoustics.) My solution was to zero the mics back out and tune them together. I found that when I started to get a frequency feeding back, I could usually turn off a couple of mics and turn down the frequencies on those mics. The next frequencies I would find a couple of different mics to turn down. I a frequency came back at a higher level, I would have to find a couple of different mics and turn them down part way. I went through this going back and adjusting which mics were taking care of which frequencies in order to optimize frequencies for the different parts of the choir. That's probably not the solution everyone needs, but if you are having a problem turning all the mics on after having rung out each one, consider treating them as an array. My explanation for how an array works in feedback: take two microphones in an array. Mic A hears a resonant frequency in its part of the room, but doesn't hear it coming back from the mains. However, Mic B hears the frequency in the mains and feeds it back into the system. Reducing the frequency in either mic will eliminate the feedback. Just multiply this dynamic by however many mics you are using to cover an area, and you have a fairly complex system. Do you use less mics each covering a greater area, or more mics each covering a smaller area? In the first scenario, more gain will lead to more feedback. In the second scenario, more mics will lead to more feedback. You just have to play with it to get into a sweet spot.

[@AttawayAudio]

Another way to try this would be to EQ each individually, and then make a group to EQ out the frequencies that would bump up from the combination. Each time you add a mic, you add to the total gain, so it makes sense that there would be additional freq's that want to ring.

[@jimpemberton]

@@AttawayAudio Thanks! I'll have to try that. It's not as easy to do on our current board, but we are due for an upgrade and the system our consultant recommends would do this pretty easily. We use so many mics to combat the room's drawbacks, and use Astatic variable polar pattern mics to narrow the area each mic covers. That helps out some, plus alternating polarity and panning troublesome mics away from the side they are closest to. I'm using every trick I know and I'm open to tricks I don't know yet.

[@romerbass2813]

Fanstastic! I have to get an RTA corresponding somehow to my analogue mixer...

[@snideremark]

If you have an iPhone I found an app called sonic tools. It is not even close to smart in any way but I was able to use it to do this with out an rta. It works the same in a very rudimentary way.

[@snideremark]

How high do you low cut choir mics? I used this trick with an rta app on my phone and already has made a huge difference. I’m micing a K thru 8th grade chorus so it doesn’t even have to sound good. I just need it to not feed back! Thanks for this video James, four years later it’s still helping.

[@AttawayAudio]

200 Hz is a good starting place. Move it up until it sounds thin, then back it off.

I've rung these things out over an over but I still can't get much gain into them unless I pan it more to the right side. Unfortunately there's no moving the choir. Any suggestions would be great.

[@ilia_amb]

What a great video. Thank you for perfect and amazing points .

[@michaelanderson4265]

Where is the gain set before pushing up the fader..? Do you ring out the monitor feedback before the microphone(s) feedback..?

[@AttawayAudio]

Great question! If I'm doing this before any talent arrives, I may go ahead and set gain by putting the fader at 0 and then rolling up the preamp until I get feedback, notch it, and then keep rolling up the preamp. This way I know that above 0 on the fader is the edge of how loud I can put it, but I'm safe below there. Then if the talent arrives and I need less preamp, I can always turn it down.

Hi! Thanks for the tutorial! How much you hipass mics?

[@AttawayAudio]

For choirs that don't have bass singers, you can go up to about 200 Hz without any repercussions. But definitely play with it and see if that makes it too thin and back it off.

[@markulrich3861]

Thank you for sharing your knowledge and experience. I have had allot of trouble with choir mics. Our church has Shure SM81s which are recommended for choirs by Shure. I have tried multiple methods and cannot seem to get enough signal to mix the room properly. It's just weak. The SM81s just always seem weak. I have the mics set at 0 DB (no pad) and used the 18 DB high pass filter roll off setting. I was able to set gain very high and used your method of ringing out the mics, which I like better than scrolling with the parametric EQ points. What mics are you using, do they have integral pre-amps built in? They sure sound great in the choir video. I am miking a 15 person choir, two rows deep, 7 in front and 8 behind staggered. Shure says to use three mics at six feet apart, two feet from the from singers (3 to 1 rule). Our budget will not allow for different mics at this point. Suggestions for better signal levels at the mixer?

[@AttawayAudio]

For now, just forget about the 3:1 rule. Place 2 mics at the 1/3 point of the choir, and back it up JUST enough so the person who's right in front of it isn't louder than everyone else.

[@coldcanfactory6879]

Thank you for the video! Did you EQ directly on the mics Equalizers or on the EQ for the speaker? Also, do you do the same on the lead?

[@AttawayAudio]

I put the EQ on the mic channels that were most likely to feed back, so just the choir mics. If I did have a lead vocal mic that was prone to feedback, I'd try the steps in this other video first, and then, if all that didn't work, I'd do the process above for that mic. But that should only be one or two frequencies if everything else is working properly. kzbin.info/www/bejne/jmHWl2WQqrZ-fa8

[@fettefritte5592]

what software are you using?

[@patrickobichere8939]

only question I have is how did you set the pre amp before raising the faders and ringing the mics out.?

[@AttawayAudio]

As I'm starting, I put the fader around -5 or -10 or so and roll up the preamp til it starts to feed back. As I get rid of more frequencies, I'll push up the fader more. Gain before feedback doesn't care if the gain comes from the fader or the preamp, and if you know where the highest point you can put your fader before it feeds back, that'll help you adjust your whole mix around that element to keep it from feeding back, but stay in front

[@eugenesidelnyk4600]

That's pretty interesting, however in my case after ringing out mics separately, when I enable them all and turn the volume up, it is not possible to have the same level as on individual.

[@AttawayAudio]

Yeah combining them raises the overall level

[@eugenesidelnyk4600]

Btw, how do you deal with the low end on choir mics? Or are you just ringing them out and that's it?

Hey what happens now that you used all yr bands and now dont have any more bands for TONAL BALANCE

[@AttawayAudio]

Use a great mic in the right spot so you don't need to. Or you can bus them all together and use the EQ on the bus.

[@livemixpriyan]

Thanks for the Video. I have some questions. 1. I Think you cut the frequencies of the microphone channels. Why didnt you cut those frequencies on the monitor channel instead of Microphone channel? Wont that change the Sound of Voice? 2. If there are 3 to for frequencies to be cut. then after using the PEQ how can one EQ the voice to Attenuate or boos some freqiencies of the voice to make it sound sweeter or nicer? Thanks in Advance

[@AttawayAudio]

The mics were close to the mains, not the monitors. The narrow cuts don't change the tone much. And hopefully the choir just sounds like they should, and the mics don't have weird tonal things that need correcting, so you don't have to EQ more. If it was a close-mic'd vocal, that's not usually the case.

[@livemixpriyan]

@@AttawayAudio You mean in case of Close Mic's should we eq the Monitor to Ring out?

[@mattiaippolito1625]

Hi. Nice video and well explained, but If you use the peq to avoid feedbacks....what do you use to eq their voices?

[@AttawayAudio]

If you choose the right mic and put it in the right spot, it's likely it won't need much EQ. I talk about that more in this video here: kzbin.info/www/bejne/pqazmI1pm52JjcU

[@MAGrimsley]

I realize that I am watching this 3 years from when you posted the video. I am curious as to what software where you using to show you the frequencies for the choir mics feedback that allowed you to cut those freqs.

Very good information thank You for what you do

[@miguelpessanha]

Is it feedbacking on the PA or mons? Were you applying the EQ to the choir mics or to the wedges? Thanks for sharing!

[@AttawayAudio]

It's feeding back through the PA, and I'm putting the EQ on the mics themselves.

[@KompaKing]

@@AttawayAudio great tip but if I am using the bands to ring out, how am I going to EQ the mic if I have no more eq bands to use?

[@matheusPMAVieira]

In my church every Christmas we have a big musical with choir, vocals, band and a big orchestra! It's very challenging to put the choir in the front mix without feedback! And they still need monitors!! Witch mics you use for choir?

[@AttawayAudio]

I typically reach for a small diaphragm condenser, and the flatter the response, and the more off-axis rejection (and smoother off-axis rejection) the better. If the choir sounds good, and the mic sounds transparent, you won't have to use EQ bands to fix the tonality. The ones in this video were some Audix miniatures that I found... not even sure of the model. 🤷‍♂️

[@gavintichenor7619]

What did you have the gain on the mics set to? We have hanging chior mics that I'm struggling to get volume out of.

[@indikasampath5440]

Hi i follow ur great videos ..got some questions..1. Do u perform this step after calibre the pre amp level ? 2. Is it the same mic ringing after cutting the feedback frequency, if so why a single mic has multiple feedback frequencies ? 3. Whats da software used for the spectrum analysis ,or its built in for mixer ...Thanks

[@AttawayAudio]

1. I do it as I’m setting my mic pre levels, because I want my fader to live around 0 with a few more dB of headroom before it rings. This way I know visually how far I have before it’ll feedback. So the steps go hand-in-hand. 2. Every mic will have more than one frequency that will feed back, but you start with the “loudest” one, and pull it down, and then you can push the level up further to get to the next one, and turn that down. You have to get one out of the way before you can isolate the next one. At least if you’re working methodically. 3. This program is Smaart by Rational Acoustics. But a bunch of mixers have an RTA built-in to the EQ screen, which is SUPER helpful. Thanks for the questions Indika!

[@burhanuddin127]

Sorry if I'm wrong but isn't graphic eq in essense a parametric eq but with fixed state? And those other bell shaped ones are state variable but both are parametric...

[@AttawayAudio]

A graphic EQ is in essence a fixed bandwidth, fixed point EQ. But if you're not careful, there can be phase shifts between the bands (that's how EQ does its job - it varies the phase for that frequency to cancel it out some or cause constructive interference). So if your graphic EQ is has too much change between two bands, it can cause phase issues and make it sound weird. Parametric EQs can be smoother phase-wise. And on the SSL, the parametric EQ has such fine controls, I could really dial in what exact frequency it is, much closer than I could with a 1/3 -octave graphic EQ.

[@xRUSSIANMEx]

Also. To tune out frequencies. Do you select each mic and use its own RTA to show. Or a over all RTA for the whole sanctuary?

[@AttawayAudio]

No I just have a single mic at FOH feeding the RTA

James, can you explain a bit about what type of input is your SMAART spectograph is reading. Is it channel PFL from the desk or a reference room mic?

[@AttawayAudio]

In this instance, Smaart has a reference-style mic as the input, but a PFL would work, it just takes an extra step. And I mostly use Smaart while mixing to quickly identity problem frequencies in the room, so the mic is more effective for that

[@timsmith3689]

@@AttawayAudio So should you connect the reference mic direct to the PC running Smaart or is patched from the mixing desk? Sorry for the basic questions!

[@AttawayAudio]

No problem! We have an audio interface with a mic input that feeds the computer, so it doesn’t take any channels or routing on the console. If we were taking a Transform measurement (comparison of signals), then I would route a mono-summed signal from the console to a second input on the interface so they could be compared at the same time.

Yes, a changing environment definitely changes feedback frequencies, but people will tend to absorb frequencies rather than reflect it. But if they introduced new reflective surfaces, the potential for feedback goes up. So watch for reflective surfaces

could you tune the system with this method by puting a mic in the medle of the stage, so yo don't have to do this to the intividual mics?

[@AttawayAudio]

Not exactly. You want to EQ the speakers to sound good, not to get rid of feedback. You wouldn't want to EQ the speakers that are going to the audience based on what's being heard on stage. Plus, it's not all the inputs that are feeding back, so you just want to EQ the individual channels that are feeding back; and as you see in the video, they don't all feed back at the same frequency when they're in different places, or even different mics.

You’re very welcome Brec!

[@didl3600]

Nice video. Please where did you place the mics?

[@AttawayAudio]

I spaced them evenly across the front of where the choir was standing. They weren't here for this part, but I posted a cell phone video of it on my fb page AttawayAudio

[@didl3600]

Thanks James

[@bearklenda7409]

How were you able to isolate the choir from the full band with the mics and choir where they were located?

[@AttawayAudio]

Stage is relatively quiet. Amps underneath stage, drums in a cage, no monitor wedges for band.

[@MGort-bb8op]

If I may ask, what do you think about the dbx AFS2? On paper this device should work awesome regaring filtering out nasty frequenties.

[@AttawayAudio]

I haven't actually used one, but I think it is great, but has its limitations. What if you have 4 mics but only two channels of processing, and each mic feeds back at 3 different frequencies? Eventually it runs out of processing power.

[@MGort-bb8op]

@@AttawayAudio I would use the device as insert processor on a "speech" bus. Sending all the same type of headsets to one of the two inputs. Thanks for your answer.

[@Kuuuks]

How do you use the same Graphic EQ to knockout problematic frequencies and be able to also us it to fine tune the Mics at the same time?

[@AttawayAudio]

Great question! Beyond changing mics to get the base sound you want without EQ, you could patch in another EQ on the insert from a rack, route them through a group and use EQ on that, or just make a compromise between gain-before-feedback and tone.

[@Kuuuks]

Attaway Audio I always wondered how to get both.... Thx much 👍🏾

[@maheshamberkar3187]

Hi Wanna ask. Monitors are Eq d according to Microphone feedback. What happens to the band (Music) tone. Or you only Eq Vocal Aux?

[@AttawayAudio]

I put the EQ on the mics, not the speakers, so only those particular inputs are affected. Hopefully the eq notches are narrow enough that it doesn’t affect the tone. Your ear can tolerate a big narrow cut and not notice it

[@burhanuddin127]

@@AttawayAudio so do you ring out only choirs or do you do it with all other mics as well cause usually while ringing out, one will eq the monitors or mains and not the mics to prevent tonal changes of the source. What is it that you do? Thanks.

[@MarkAMensah]

don't you think we can lose sound quality when cut out all the frequencies causing the feedback?

[@AttawayAudio]

of course. that's why i recommend doing whatever ELSE you can to get better gain before feedback. but your ear can tolerate narrow cuts without it feeling weird.

[@MarkAMensah]

You are right and I've learnt a lot from this vlog. I have been cutting my feedback frequencies on the GEQ of my main mix but I have often ended up with poor and distorted sound. I'm going to reset my GEQ and instead focus on the EQ of each mic input like you have demonstrated.@@AttawayAudio

[@latchors]

Great content, I really enjoy your videos, but something is bugging me about this one, since you use the parametric eq of each mic to get rid of the feedback and they are limited, then you cannot eq the mics, am I correct? Is this part of the compromise or you have a solution for that? I'll be waiting for more videos :D

[@AttawayAudio]

Great observation! Yes, using the channel’s parametric EQ limits what I can do to EQ the signal musically, but the key here is to choose a mic that, without the feedback issues, sounds good on the sound source in the first place. You don’t HAVE to EQ everything just because it’s there 😀

[@KompaKing]

@@AttawayAudio found my answer lol

[@adi.sax.ardelean]

Hello. Do you do this thing on the microphone channel eq or on the master eq? do you eliminate problematic frequencies with the soloist's microphone or the small rta on the master? thanks

[@AttawayAudio]

I try to make my EQ as non-destructive as possible, so I EQ individual channels first, then maybe group them to EQ some more if I have to, and then POSSIBLY EQ the main output, but I try to avoid that

[@veerababudaraaudiomix]

Thanks for this video sir

[@AttawayAudio]

You’re welcome Veerababu!

[@andrewmilbrandt406]

What RTA would you recommend as far as an APP, we dont have the set up for SMAART yet and I need to do this on a couple of mics?

[@AttawayAudio]

Any RTA app can work, but the higher number of bands available means you can be choosier about which exact frequency you're notching out

[@andrewmilbrandt1912]

@@AttawayAudio I found out that our Si Performer isn’t great for notching out frequencies. But thanks to your video I was able to get rid of a couple of feedback frequencies.

[@matheusPMAVieira]

When is better to eq monitors beside mics?

[@AttawayAudio]

Great question! It depends if the feedback is coming from the mics going through the main speakers or the monitors. I try to avoid putting the choir mics in the monitors like the plague, and if it's POSSIBLE use baffles behind (or even above) the choir to help them hear themselves acoustically. But if you have to put the choir mics into the monitors, then you would put the EQ on the monitors themselves, and if you run out of bands and still don't have enough gain before feedback, then go on to EQ the input channels on the mics. Thanks Matheus!

helpful thank you

You're welcome Shiji!

[@markgregnisperos1818]

How to do this on an analog mixer sir?

[@AttawayAudio]

You'd need a parametric EQ with as narrow a bandwidth as you can get. Or you can use a graphic EQ but I avoid them if I can.
