Tuning speakers with Open Sound Meter and M32 / MR18 

Thanks Michael 🙌🏻 i appreciate it coming from you

@@danielkharrat You got it! Keep up the good work.

I really like both your Channels! With Drew Brasher you three made my career kick start! Drew with the overall Tutorials on my Mixer, Daniel with Sound Concepts, and tips, tricks and tweaks & Michael with his charming character & knowledge which he provides. Thanks a lot guys! I really need to say thank you!

Disregard it was a driver issue 😑

Watch out for reflections. If there's a hard surface next to one speaker and it's causing delayed reflections it might make the speaker sound too boomy or to bright...if you can put the speakers side by side away from any walls or har surfaces, and listen to one of them then listen to the other one If they sound the same, your problem is a reflection If the still sound different, the problem is in the speaker itself

I think it is worth noting that speakers DO WEAR OUT... !!! All speakers are linear motors, and all motors wear out and break down eventually (to use an automotive comparison). The earliest wear points for a LF driver are the surround, the spider and the tinsel leads from the voice coil to the connector tabs or posts. In a HF compression driver, it depends a lot on the material the diaphragm is made of, but aluminum and titanium can develop cracks along the "surround" area (it's not really a surround, but it is a thin area with the greatest stress & movement). This is super simplified, and assumes NO ABUSE of the speaker, accidental or otherwise. If the speaker has been abused, you can easily have damaged, but not completely burnt out drivers that give anywhere from a somewhat to vastly different sound to a new, perfectly functioning driver. You didn't mention HOW the speaker sounds different, but here are a few notable examples I've personally repaired whereby the speaker was still functioning to an extent, but sounded vastly different that a good one: HF titanium diaphragm shattered by excessive power - still produced some HF, but distorted & very low volume. HF titanium diaphragm cracked along the "surround" - reduced HF volume, odd distortion at some frequencies. HF Mylar diaphragm & magnetic structure contaminated with dried beverage - sounded nearly normal but with distortion at some frequencies. LF surround partially de-bonded from cone - weak floppy bass with notable distortion at some frequencies. LF spider de-bonded from frame - lots of distortion & clacking noise from voice coil rubbing / hitting magnet. Might be worth running some measurement tests on the speakers to ensure you don't have a driver fault.

the speaker was hanging on the ceiling with no walls the problem its on the speaker itself.... can we just tune each speaker to match each other?? I know its a lot of work ... thanks anw@@danielkharrat

well the speaker its relatively new.. I thought wearing its not the problem thanks anw@@radioflyer2030

@handihasan8823 you can do that if the difference is not huge. If there's 5 db or more difference in certain ranges you can eq it theoretically but it won't sound good

No the filters i apply in open sound meter are a prediction of what will happen if i do the same moves on the console After i know that this filter at this frequency with this much gain and cue will do this to my sound I go and do the same eq move on the console

Get a usbstick

@@curly_ thx, I finally managed to get what I wanted. Unfortunately it is only possible by using a USB drive an saving a scene to it which must be (re)named "CustomBootState.scn". Everytime you switch on it will ask you if you want to load that scene. So I took it even further and named it "CustomBootState_NoPopUp.scn". Since all our M32 consoles are equipped with a dedecated USB drive anyway, it now works perfctly. Everytime I switch on, my default scene is immediatly loaded. Saves tons of time. No more routing or programming required in 99% of my setups. Using cutom channel presets, it takes little to no time to get ready.

It plays normally on my side

Thank's @@danielkharrat

No

No it works on macos and Linux also

@@danielkharrat what about ipadOS and Android?

@Elior1030 iPad os yes but it's not free Android no

@danielkharrat ok, thank you sir.

I hope you are referring to setting up a couple speakers on sticks & a couple subs at a local bar.... I roll out to a local artisanal brew pub to do sound for some hacks every couple Saturdays, basically in open air with a permanent awning, and I just throw down some K12.2's & a couple 15" subs & done. But I'd never dream of setting up the array system at a festival, or doing the installed sound for a rock & metal bar or dance club (or an ancient stone church) without proper measurement tools. Sure, you still need listening skills, but human ears are so easily fooled, more so when the eyes are not blind folded. Sorry, no offense intended, but if you are referring to all venues, all circumstances, this is a really terrible take on giving the audience the best results.

​@radioflyer2030 , I think I understand what they meant as "be able to identify issues by ear" is more about the differences of why something isn't right, and what is. Measurements for accuracy in correctional delay timing is really, really important. I dont think the comment was just disregarding it altogether. Without tools, you can get close - but it's really a science of physics... ya know?

I don't agree, A lot of great, professional sound engineers have had their ears so battered during their career that any visual aid is a welcomed gift.

A live sound MIXING engineer should use his ears, but not a system tech... I mean can you hear phase or can you average with your ears.... come on man... Audiofiles scared of measureing their eqvipment😂

@@laszloturi9633 Lolz... you must be a first worlder... in my country, you are always BOTH (mix eng & system tech). I'm frequently amused that our 3rd world restaurants & department stores have 2 to 4 times more employees that their first world counterparts (and still often have sub par service), meanwhile they will send you to do sound at a festival with a guy (or maybe two) who's only skill is lifting things, and think that is plenty good enough to get the job done. 🤣😂🤣 (BTW, I say all this in a lighthearted way, just highlighting the differences between first world ways and 3rd world ways - no offense intended to anyone from any part of the world).
