- It’s our job as FOH and system engineers to minimize variance, but we’ve got to work within certain acceptable amounts of variance. We want every seat to sound like the front row.
Today we walk through seven key things that change as you move throughout your audience and how to listen and evaluate them.

Your knowledge never ceases to amaze me. Thanks for all you do in the industry!
It’s amazing he makes these videos for free
@@BobJones-bh9qz Y'all are very kind!
Hey, could you make a video on PA placement for a boiler room type event? (stage in the middle, with the audience around it)
Good points to consider...I'm looking forward to a follow up video of your "Faders too Low...." video 🙏
Great video Michael, this is an excellent summary. About the subwoofer point: it is clear that outdoors having a single subwoofer cluster is the way to go, but what about indoors? Could we get a better distribution by randomizing the interaction between the subs and the room modes by placing them at different places? Or do you think this will make things worse?
As Michael says at 9:48, L/R subs will interact and cause comb filtering; and they will *also* interact with room reflections (eg. from walls etc), so it's actually worse indoors.
Why seam align? Comb filtering in those areas that someone perceives the same level from multiple spl sources?
I’m surprised you did not mention the haas effect for localization. Any thoughts on this?
Ah yes, great point! I guess that goes under the idea of time alignment, but a more specific of it.
Hi, sir Michael, I have a question?. What will be the outcome if I time-align my system with my mix position?
Question. I cannot find gll files for a particular brand of speakers that i am currently using at my church. Is there anyway for me to use the default, generic speaker in Ease Focus and input my speaker configuration to get not fully accurate but atleast something to tune
I would find a similar speaker with the same coverage specs from another manufacturer and import that into EASE.
@@MichaelCurtisAudio alrighty..thanks
How do you find the time to test for all of this? By the time I get set up, the band is ready to sound check and the venue will not open for me any earlier.
You're right, it's of course gig dependent. Sometimes it's a rush and there's not much time, sometimes I'm commissioning an installed system and I have all day.
These days I'm not doing many bar/small band gigs. If you're working in that venue frequently maybe you could ask them to come tune the system one morning before they open?
@@MichaelCurtisAudio I'm moving up to the small festival type stages, but sometimes I still do the bars and breweries. I did find your video on what to do if you don't have time. And I found it very helpful. Thank you for all you do with your channel!
As an AE for a competitive high school marching band, this challenge is all too real when going to a new field every week. Especially with a *4 minute* setup time and 0 opportunity to map the seating and ensure my array splays are proper for the current venue. *cry*
Are you doing grandstacked line arrays on carts?
