why am i not seeing this till now!? great vid chris!
Yeah, the YT algorithm has been hiding this one away from us
I am also watching after your vid. Good job Jake G. We also do a prosumer live stream from Africa - Kenya but it needs some more input. Would you take a minute to see what we do and recommend a few? Let me know so I can share a link is it OK to just share here?
both channels are nice!
Awesome stuff! I'd love to see more breakdowns like this.
Amazing video! Please keep releasing more videos showing around your main campus and even your tour set ups! God bless
Super interesting! I remember that when I visited (in 2018), the room felt comfortable to just *be* in, and I mean acoustically. It's so much easier on the ears when there isn't too much reflecting and scattering sound going around... cozy!
Lots of useful and practical ideas for good acoustic sound. Thank you
Gold!!!! Thank you guys!!!!!
Chris is such a Legend!
Thank you from Russia! Keep recording new details about your solutions.
amazingly helpful thanks Chris!
Thank you! Very awesome to learn more about great live sound!
I love amount of though and work you did with the sound absorption on the stage and with the the room treatment. Sadly, most of the venue suffers from bad acoustic treatment even if the PA is top notch.
So cool. I could hear your voice/acoustics change when you were next to the wall absorption material.
Awesome video bro.....hope you would bring more videos like these...!
Great info! Thanks
Thanks for the walkthrough. I would love to see a video of your general scene setup on the Digico.
There is a whole training greely's show. Over on our website you can get the course.
Awsome vid
A walkthrough is so much better than a PowerPoint slide 😁
Question to all: why aren't diffusers used much, if at all, in many sanctuary environments?
Because the solutions aren't designed by acousticians! haha. Diffusion is important as well. Things are changing a bit. I've seen more diffusion.
what are the sizes of the acrylic panels on the drum shield?
if custom, where can I order them from?
I'm interested in building something similar for my church.
Thanks in advance.
Awesome video!! Are you all also treating the ceiling? And would LOVE a video on your approach to tuning the PA.
No treatment on the ceiling.
It helps. T.y
I've actually been there and experienced the room. Although I thought it sounded good, I do think the room didn't feel live enough. The verb in the mix did not sound natural, so the energy wasn't there naturally. But I know you do a lot of live recording and streaming so I know that helps.
Thanks for the walkthrough! You briefly referenced the subs which was stage right... I'm assuming ground-stacked - but do you only push from one side? What does your sub array look like? Using a Gradient / delay to shape at all? And if split left/right how to you overcome lobing? Thanks!
I can say we have 1 700Hp sub per side on the floor. I can’t really speak to the tuning tho.
I built those panels :)
Where can I get this mineral wool and what density do I get? Also, are the panels in the auditorium also 4” like the stage? Thanks! Amazing video!!
We made a lot of the panels ourselves or we use Prime Acoustic for their panels. The room ones are 4" but built into the walls. If you need help with treating your room or need materials. Feel free to contact us on our site!
Vcs não utilizam outra mesa para o palco?
That is so amazingly helpful. Any idea of the dimensions of the drun shield?
Ross Adams I’m pretty sure I saw Drake Kelch say that it’s made up of 4’x6’ Plexiglass sheets
Awesome! Thanks for this. Question: in a room your size, is your PA made up of just line arrays and subs, or are you using any kind of fills through the room?
Andre de Jager we have two out fill speakers for the very corners of the room.
@@DrakeKelch Thanks Drake, really appreciate the reply
What’s the RT60 of the room?
So I have a question...you put acoustic treatment behind a guitar amp to stop reflections from getting into the mic, but isn't a drum screen doing the same thing? Reflecting loud percussive sounds back in the microphones, and with drums you have several different toms, snare, kick, reflecting back into several mics. Can't this cause phasing? I'm not being critical, I just want to know.
This is awesome. You said the room still has a “low RT”. What does that mean?
DAVID FUNK I’m assuming it means Reverb Time (an RT60 Measurement)
RT (I think) is the time it takes for the natural decay of the sound in the room to drop by 60dB.
Think popping a ballon in a room and measuring how long it takes the sound to decay by 60dB. It’s a metric that room designers use when defining how a room responds to acoustic sound!
@@tclarke1123 It's the time taken for sound to decay *by* 60dB...
Simon Lewis thanks for the correction.
Hey @DAVID FUNK, RT time stands for Risky Toilets.
Basically when you have low amounts of Risky Toilets in a venue the better chance you have of putting together a great balanced mix, having great quality toilets and great plumbing will help accentuate that desirable low end rumble you want to get out of your PA. Hope that helps answer your questions regarding RT
What is the measurements of you’re sound panels around the church?
Did you all create the mineral wool treatment fixtures or could we get a link to what you used in the amp room, back/side stage and walls?
We either make them all or buy them from Prime Acoustics. Octane sells prime acoustics if you need some!
Now I have to aim my bass amp differently 👍
I hope it helps!
It wont help. And 4" of mineral wool doesn't stop low end
Your best bet is to use inears. If you need to feel it just have a sub on stage. Most all of your mics on stage should have a high pass filter on them so it won't effect the mix. A bass cab will
Dan Jones it’s been working for us for years. All our live records are using this method.
Brutal
That was incredibly helpful! Any idea what the dimensions of the drum screen is?
8' wide by 6' tall. The Riser is a 8x8 riser.
What are the little clips that hold the plexi together?
Thanks Chris for the video- why do you keep the bass rig on stage but not guitar amps? Why not put bass rig out the back off stage too?
The bass amp is for the bass player mostly and not really for tone. It allows us to keep it at a lower volume. VS the Guitar amps need to be louder to get the tone we want out of them.
Amieeeenn
Where can one purchase the material used for the wall acoustics?! Thanks
Hey Chris, I was wondering that little block between the amps was? Was it just acoustic foam, or just a block of wood with some little carpet on it?
Matthew Alves I think it was a small sorber panel from clearsonic. Just a small square of mineral wool essentially.
What Mics do you have on the guitar amps?
Noob question from my side. Why not put the bass amp in the isolation room as well? Give the guy his bass in the IE-monitor and cut down on stage sound even more?
hey bro, whats the Sqft of your worship building? is there any point using line array if my church is much much smaller than yours? (our church has high ceiling though)..thanks
Brian Ho it’s a 1000 seat room. But we’ve put line arrays in way smaller 300 seat rooms. There is always an application.
Hi Chris, what about the roof? Is it also treated with some acoustic material?
Nope!
awesome video. i have some questions. when you say 88 db mix is that peaks or minimum and the peaks are more?
john paul porrelli peaks.
I wish I could achieve that. How did you come to the decision of 88?
That is extremely low volume.. I’m surprised. That’s good I guess but surprised.
Alguém traduz pra gente aí galera ,os brasileiro que concorda aí da um salve
88db mix. With drums? WOW didn’t know it was possible
I am sure, it is 88dB(A) with long integration time. Tough even so it is ridiculously low. I guess it is an average and not peak.
that is PROB true....look at all the dang gone baffles!!!
We have a drum cage and it does really well at blocking the cymbal noise from coming out. However, the issue we have is the lower frequencies of the drums spill out too much. To compensate we turn the drums down in the house, but then we get a muffled drum sound coming off the stage. Our cage has a top and a back but we have no sound panels on stage. I’m curious how much their sound panels help with this and also whether they have anything on the floor to help dampen the drums. Thoughts anyone?
100% need panels on the stage, at least the back wall to act as a bass trap.
@@DrakeKelch thank you!
Where are the amp baffles from!?
Those look like Clearsonic baffles
Great video. Thanks! A few questions tho:
AMP ROOM:
Do you think what you've done with your amps has been better than putting each amp in a separate enclosure?
BASS AMP:
Your bass amp on stage. I'm assuming you still line it out to the console right?
Does the bassist still use in-ears?
And does he just have some volume coming out the amp just enough so he can "feel" it?
Thanks!
ok...obvious question....but why NOT just put amps on stage and instead of using a mic use a line out with a DA??....just seems like OVERKILL
Amp Room: its way easier and more function this way and sounds just as good. Bass Amp: we mic it and have a direct out of the bass amp. It’s just enough volume to feel it. Everyone on stage uses in ears.
andrew armington well. You’ll never get that 88db mix with amps on stage. We are going for sound quality. You should go check out Greelys mixing class on octane avl to hear his mix it will make more sense.
Drake Kelch Thanks man. Makes total sense. Gonna have to try that 👍🏽
Drake Kelch So you run 2 channels for bass then? And EQ them differently I’m sure?
seems very easy when you have that budget.
Withe equipment all can do it... Jajajaj bless.
Where did you get that drum shield? Is it connected to the platform?
custom made. It sits on the riser.
@@DrakeKelch helo, come and join us to our channel, may our video, worship. God bless u and fam
They mix to 88db? Wish he would have expounded on that a little
MrTaylorMusic We do mix at 88db for our 8am service! 90-92db for the rest of the weekend! Check out Chris’s Class on Octaneavl.com or Productiononline.com to learn how to get a 88db mix!
Drake Kelch so the 88 is just the average? I’m sure with peaks above that and even more for your later services
MrTaylorMusic for our 8am service its 88db peak. Sometimes others are the same. Other wise it’s 92db peak.
All for the small price of $300k. 🤣🤣🤣🤣 I’m not hating, I’m being honest. You guys did it right. I wish most pastors and ministries could really understand how much of an INVESTMENT room treatment and the house mix is.
Unfortunately to add to your point, there is no way they did this for only $300k, that Meyer PA only cost that much.
Can you give info on the drum shield?
Brandon Reed 4’x6’ plexiglass sheetS
good Jezus....the money that is in baffles is baffling...LOL
INTERNS!
I though bass was more or less omnidirectional. Does turning the bass amp really make that much of a difference?
Jonathan Page absolutely. Having your amp face forward can really impact your subs in a bad way.
Why aren't the amps pointing at the right direction in the first place? why does it point towards the sound absorption? it's like shooting light into a black hole. why? shouldn't the sound be adjusted to the right volume and pointed at the audience? Also - soaking up sound (sound absorption) is not the same as sound isolation.
Drum-shield: you can improve the drum shield by sealing up the gaps and using thicker (double pane) material and puttig absorbing treatment on the underside of the roof part.
Is there ceiling treatment in the congregation space or just wall treatment? what is the mineral wool density and thickness? do you also have the 2" gap behind the congregation space treatment?
Guitar amps are miced up. It allows you to control the volume of the room without having to make the sound system too loud to over power the stage volume.
I don't like being in a drum shield/ box but its better than the sound guy constantly telling me off for being too loud. Heck he still tells me of with the drum shield!
did my guy really say an 88db mix? that's soooo quiet
But it still sounds huge!
I can show you how to do it without a drum shield. If you want.
Camera Coverage is poor. YOu needed to actually see the things he was talking about
Драмшилд-кака!!!!drumshild💩🙈💩🙈
drum shields are 100% unnecessary in a 1000 seat auditorium
I think it’s ironic that they’re talking about such amazing sound at bethel, but they can’t even get their own sound right on an isolated vocal mic lol
its all about making money and peaching unbiblical nonsense with bethel!
