I kindly suggest that a live desK in 2024 MUST have a simple way to switch polarity on outputs.
I use a dLive S5000 for years now, and sometimes, I use matrixes individually delayed to set up arc subs without any lake or so…
When you smaart your system, it’s common to have the subs line aligned, but out of phase vs the mains.
…I spent hours to find a way to fix it on the desk: I always end with my phase inverted XLRs… No polarity switch for outputs, not in routings, not in I/O, not in the channel options…
Frankly, it’s unbelievable that’s it’s not implemented yet!
Maybe it is: there is an option “outputs polarity” in the safe recall page (others)!!, but if so, it is soooo hidden that a full band of experienced users didn’t find…
Pleaaaase A&H: you built a marvellous sounding desk, but why a ridiculous (but easy and cheap to fix!) mistake like that? Just a few lines of code…
Polarity on outputs is related to the socket rather than any channel.
Touch the output socket number in the I/O screen to open a pop-up with options for the socket, including polarity.
This is shown on pg42 of the current Firmware reference guide https://www.allen-heath.com/content/uploads/2024/09/dLive-Firmware-Reference-Guide-V2.0-ISS-3.pdf#page=41&zoom=auto,-218,227
Thanks,

Great thanks Keith and andia! I was looking for that for yeaaars!
Ok, I assume that we have to read the manual, but I’m pretty sure majority of professionnals don’t do it extensively. I rather look the summary when I look for something , and there’s nothing in summary! 
I own a SQ5 + DX168 too, is that the same for SQ series?
Good to see that A&H support is really supporting! 
The real professionals do read manuals. Maybe we skip the first chapters.
Nice to meet you Steffen! I believe you’re a little fast and furious in your judgment…
I work in the field for more than 40 years now, recorded more than 120 lp in studio, was FOH engineer for more than 2000 concerts, tech director for 20 years…
Nice to learn that i’m not a “real” professionnal, and that I stole my food! 
I DID read manuals when I was a young, new and enthusiast sound engineer, mainly because I needed it. Now, I really have no time for that, I change desk almost every show! So, I turn around the UI, and 99,99% of the time, I can do what I need to do. When I have an issue, I ask the other professionnals, who, strangely, never judge…
Sorry, I can’t spend hours reading stuff that I already know for the main part. I just check how to do particular and rare things. And polarity switch is not rare nor particular!
Maybe it’s because after 40 years driving cars, you don’t read the manual when you get a new one!!
Real professionnals know how to drive, any cars…
If you’re not here to help, but to judge, maybe you’d better go!
Salutations
How do you work successful in your job without reading manuals?
Such a simple thing like polarity flip for outputs is easily searched in the manual.
The technology changes and new stuff needs some additional knowledge, sometimes.
And the use of functions is different from device to device, so reading manuals would really help sometimes.
To ignore a technical device’s manual is shortsighted.
I do not need to learn how to drive the car,
but I need to learn what the new driving assistant system can do for me and how to activate it.
Or which switch is doing what, since the symbols sometimes differ.
Many younger engineers watching YouTube tutorials now. Or you can search on the internet how the driving assistant works.
But reference for the functions still would be the manual of the manufacturer.
