I have 4 subs but none of them have built in DSPs. I am trying to find some sort of box for adding delay to the correct speakers so I can play around with cardioid setups but I can't find anything online. But this must exist, right? (And not cost $1,000)
Why don't you use fiberglass behind the speaker so it just throws the sound One direction so you wouldn't have to turn a speaker speaking face in the stage p speaker place in the audience fiberglass is doing its job
Here's one for the list, maybe- Make your health a priority. We're all guilty of abusing ourselves sometimes, eating bad food, making risky maneuvers when moving and rigging gear, not sleeping, too much redbull, whatever. If you're not showing up as your best self, you'll be a liability to the show vs an asset. Respect your limits, and take care of your self.
I have a question that I can't find the answer to. I have 4 subs and I want to know if, by placing them in front of the stage with a distance of 1.7m between them, do I need to apply delay between each sub and the PA?
Hi Michael, We’re planning to upgrade our church's PA system from analog to digital plus anew space but I'm feeling a bit lost. Do you offer phone or video calls for clients? I'd appreciate any guidance you can provide. Thanks!
Does the measurement mic connected to input 1 should go BACK to output 1?, you don't mention here if it needs to be routed only to the inputs of the measurement software, because by default the mic we connect on input 1 will go ALSO to output 1 and that will create a feedback loop
I’m at busker am I performance area is 15 feet. The pedestrian walk is 15 feet in front of me. Where should I set my speaker and how high? I have the fourth generation AER compact speaker.
HOW TO ALIGN DIFFERENT SPEAKERS: if you have full access to the dsp of the speakers, then its easy matchable. If you dont, i recommend, you dont mix speakers. If you have full access to dsp, do as following: 18" subbass, HPF at around 25hz to LPF 80hz, 15" Kickbass, HPF from 80hz to LPF 125hz Meassure speakers without any EQ. Meassure SPL, Phase and impulse-response Meassure and Align Speakers with their SPL, Phase and impulse response, each independently. Start with Impulse response, then Phase, then SPL. Its not just about phase or SPL. Impulse has to fit as well, to get matching Impulse (18" usually slower then 15") you have to add a certain delay to the speakers, before you start matching the phase. You have to try and error with Phase-meassure and Impulse-meassure, until the speakers match perfectly Use the same filter at the crossover frequency E.g: 18" sub: High pass filter e.g. 18dB Butterworth, Low pass filter: 24dB Linkwitz-Riley 15" sub: High pass FIlter has to be 24dB Linkwitz-Riley as well, to get a perfect summation. Sometimes, you have to add an all pass filter to the system to get the impulse and phase matched perfectly. add those filters in your dsp. you have to play with the Filtertypes to find the perfect filter for your system. Sometimes its Butterworth, Linkwitz-Riley or Bessel, sometimes even a more unique one as Hartmann or LIR. Tops: Make sure, you have matching tops for your 15" sub. If not, repeat the procedure above with the 15" sub and the tops. EQ-Settings: DO those, after you matched phase and impulse perfectly and apply them on the whole speaker-group, not just to the single speakers. otherwise, your phase will shift again and you have mismatch. Always just EQ the whole, summed signal. Important: You usually meassure the speakers at a certain position. If you move the speakers and place them in a different setup, your meassure is not coherant anymore and you have to meassure again.
I’ve seen some recordings missing kick drums because the mix engineer simply decided to run the kick only to the sub aux. Most churches and bands have volunteers, and probably someone from the band is doing the mix. Having less aux to worry about is great. A good and leveled PA is much better than mixing a separate aux.
Might not get reply. But question anyways. Will there be difference by putting a stack of 4 but all subs are looking at each other. Like number 6 just all in stack. Will it change anything from all facing forwards and all facing into each other. One more question is for rooms. I have LA 4x KS21 at home, for home use only(6x8x3) room, What you think should be the placement? all 4 next to wall? evenly spaced in the middle? def not stereo.. your thoughts if possible :)
The last set-up, two side by side, with two side by side with a 5.66ft space (front to back) firing forwad.. Two questions.. 1) What's the space between left and right subs, also 5.66ft ? 2) Are you applying any delay on the front subs?
Hi I’ve been trying to get my vocals right for singing on live streams, but when I listen back it always has that too in your face sound. I have pretty good pitch and the pitch is also slightly off listening back (although I’m picky) When I say in your face, it kind of feels intimidating to sing. It’s not because I’m not experienced enough as a singer, I don’t feel this way when I sing at a studio, or leading worship live. Do you think your tips help with that, or do you have recommendations for that specifically? I hope I’m making sense lol
Thank you for the video. My church is a 43foot long by 33foot wide space and we were wanting to get a speaker. What do you think of the Fulcrum CCX15, and how would they compare to speakers such as JBL VRX, L-acoustics or Meyers, in terms of resolution and overall sound quality? I am not able to demo these speakers, but I know you have heard them. I would appreciate your input. Thanks
Hello, thanks for your video. Whats the distance between the subs which are behind each other in scenario 7, 1/4 wavelength? And whats the controller settings for that scenario, is the back line just delayed like an endfire array or also inverted for cardiod? Thanks for your help.
As a DJ, this seems a nightmare as I could never rely on booth monitors as the sound just doesn’t make sense. In ideal I’d like to experience the exact sound as the dancers get. Dj being behind the subs - just gives the opposite bass and could never understand actual sound. Earphones are only for cueing, not for mixing. Am I the only one to see things this way?
I mix on Yamaha RIVAGE, DM7, or Avantis much more than anything else these days. And I don’t “need” to mix on anything but what the production company provides.
I downloaded the audio tool kit, but it's in read only. I am unable to make changes. Any suggestions on what I need to do to make it functional? I appreciate the help from anyone.
Thank you so much for this Michael! Just used Ease Focus 3 using this video and the other video you have on it to create my first project for a new church space we are moving into in the early Spring 2025. I'm no expert but definitely feel more confident with the tools you teach here! Thank you for providing such an invaluable resource.
Very informative video. I have like 100+ questions because I want to build my own big sound. But general question: Is line array bullsh.. for clubs? And I mean club like for 200 people, so nothing big.
Awesome video. Helping me learn. I’ve been trying to make 10 subwoofers work well together. I will work on phase and gain matching to see if I can get most out of my subwoofer summing. I’m trying to sum 3 different types of boxes so it may not be possible or give a desired result but something for me to play with. Do I need a controller to get proper measurements? In the past I have used a usb controller with in and out but lately I’ve been using umik and Bluetooth but I’m not getting a proper phase graph unless I use REW.
I took a bit of time (15 hours lmao) back and forth since day to day my perception altered a bit...but... I took the 4 subs I have and put them around the room instead of in front of the stage. I messed with the polarity until I found the sweet spot and OMG..... the dancefloor feels like you're IN THE MUSIC. The high end really didn't take much at all to manage after this management of the low end. If anyone reads this... be very aware day to day....what you do with changes and how it "feels" vs how it "sounds" Think of your audience too, not the stage and "look" of the setup. Sound is like GOLF in so many ways. VERY difficult to master, but easy to do once mastered.
I watched so many videos to find this answer that I was looking for. Thank you for making this. My question was: When should I use the phase change button (180 degrees). Tell me if I wrong but I believe the answer is: When using a Cardioid set up, but don't forget the delay. Thanks again.
Glad it was helpful! A slight tweak to your answer: cardioid sub setups is one use case for inverting the polarity of the sub. Other time you might use it is to make the phase response of the sub better marry up with a main. Those are the two main use cases.
