Shutdown is an archaic procedure, useless and not in conformity with reality. Instead, a simple “On Off”, with loss of the last settings should be acceptable.
Question: Why this procedure? Electrically nothing justifies it. The general switch often present in the rehearsal room should be enough.
Of course, the last settings are lost, but even that could be avoided by the software…
It’s hardly a gross inconvenience to shut a piece of equipment down in an orderly manner. I’ve seen many a ‘pull-the-plug’ operator bleating about a lost show or a malfunction: never understood the mindset TBH.
It has always been of my opinion that you should never shutdown any sort of computer (which I consider digital audio consoles/mixers to be) by just hitting the power switch or pulling the plug. I have seen too many computers get corrupted operating systems or software from improper shutdown procedures over the years.
Obviously no one needs to worry about hard powering off their CQ without shutdown first, as long as they have no data traffic to USB/SD at that moment.
In the early days, the CQ didn’t even have this shutdown option.
Just like “removing” a USB drive from a computer’s OS prior to unplugging it, the CQ’s “shutdown” sequence is more about managing the memory functionality of the device than anything else. Powering down the console without going through the proper “shut down” sequence always runs the possibility that the system is interrupted while writing something to memory which could cause corruption. It likely won’t cause a problem most of the time, but it could be an issue which is why the “shut down” procedure exists in the first place - to ensure it doesn’t cause a problem.
All modern OS have a shutdown procedure, so all running processes and File systems can be shut down gracly and so whatever they need to ensure state safety.
Windows, Mac and Linux, just like Android all have a proper shutdown procedure, and as all OS’es grow it becomes more and more important to follow the shutdown.
7/10 pc’s mac’s and more I have to perform “IT CPR” on, has crashed due to people just shutting off power and not tell the system to shut down properly.
Shutdown “procedure” have nothing to do wit OS considerations but with business… And all “modern” OS have a “Non Shutdown” capability to offer solutions for industry.
It is creasy to realise hom much people are redy to obei on new “necessity”…
I don’t understand your obvious frustration with users who shut down their computers as recommended.
Nobody is stopping you personally from turn off your computers if it works fine for you.
In your CQ’s case, the manufacturer has already mentioned that you can do it.
So, your CQ problem should be solved.
It’s worth remembering that (attached storage not included) the mixers in question here - CQ - are embedded devices and not computers. They’re not running an operating system in the way you might understand and so worst case, pulling the power will just lose any changes you made in the last few minutes. It’ll always resume where it was just before the power went off.
Like I said before, if you’re using the USB or SD storage devices then shutdown can be helpful because it’ll ensure that all read/write functions are gracefully stopped before cutting the power. Obviously interrupting a write function such as recording will likely corrupt your file.

The mixers are fine with losing power from time to time.
I still recommend using the shutdown command to turn off the device. It could be less stress for the electronics inside.
But to assume that all settings are lost is simply wrong.
And to have this shutdown command has a reason. No need to remove it.
That is simply not true. Normal OS is made for saving its last state to the disk to allow a fast start-up. But you need to trigger this. Pulling the power plug doesn’t trigger anything.
If you run software and interrupt the power to the device, data will be lost. Maybe some system procedures restore the last state, but most of the services and the software doesn’t recover properly to unsaved states.
But to run an OS just to have the naked OS is senseless.
We use a SQ-7 at church so our usage may be different than many of you. From a general sound system usage viewpoint, I don’t like this suggestion. We have volunteers at church that are in a rush to leave after the service and forget that the amps must be turned off first. It’s our last chance to get the amps turned off. They have a script to follow that includes “Mixer on first, Amps on last, Amps off first, Mixer off last”. They realize it after the “big pop” from the speakers but don’t remember the next time it’s their turn which is once a month. Some may say it’s a training issue and I agree, and we’ll remind them before the service but they forget. We have a hard time getting volunteers.
