    I have a new QU-24 and am getting excited to put in production in a church installation setup. I want to power it via a sequencing power bar daisy chained to the one controlling the amplifiers. Of course, I fully expect someone will power down without first shutting down the QU.
    I searched the forum but did not find much discussion on this. Will powering down a live QU corrupt the stored settings or hurt it in any way? I do not have an iPad…yet, can I shutdown from the QU-pad app?
    Advice welcome.

    It is not advisable to bypass the correct shut down process and “crash” the console. And no, you cannot power down from the app.

    The manual explains that the Shutdown option on the Home screen is there to ensure that all files being written to the USB ports have completed. If you turn off the mixer while files are being written, you may corrupt the disk to which the files are being written. This can have major consequences.

    If you are not recording or saving scene or show data, turning off the mixer without using the shutdown option should cause no problems. That has been my experience, but you may wish to see if someone from A&H responds to your question with information that I’m not aware of.

    However rare, a potential for data corruption is also on the Qu memory, not just USB – the mixer regularly auto stores current settings on board. Hence the recommendation to always shut down safely the software first.

    Thanks for the clarification. I had been meaning to comment that I would rather follow the prescribed method of safely shutting down as incorporated into the console as opposed to trusting a report of not yet having experienced any problems, but now i don’t have to.

    Better safe than sorry.

    Good evening,

    I plan to acquire a Qu-Pac, also for a church. It will be in a rack and the power switch won’t be accessible. I have understood the need to follow a specific procedure to turn it off, but, after this process, if we cut the electric power with an external switch, will the console automatically restart when we give it again?
    Best regards from France and all my apologies for this poor english language!

    Technically its the same to switch off using the internal power switch or just pull the mains plug. It is recommended to use the shutdown button on home screen so that current settings are stored correctly.
    So, yes, it will boot up as usual using an external switch.

    Hi Andreas, thanks a lot for your fast answer. I’ll stick a large leaflet explaining how to stop right next to the main switch 😉

    Question – can shutdown be added to a soft key (probably needed a long press?)

    Hi all,

    @fgrillet if the power switch on Qu is always on and you cut the power with an external switch or breaker, Qu will automatically restart when power is supplied again.

    @xapbob I’ll add this to the list of feature requests. Standard shutdown procedure requires a confirmation. This would have to be worked in.

    Thanks.

    Long press to bring the screen up might be easier for this situation though – maybe not a common request, but it doesn’t strike me as a significant development effort 😉

    Can’t recall if the console is “locked” while the shutdown screen is shown?

    The model I was thinking of is the projector style “push button for 2 seconds” brings up a confirmation screen, which says “press again if you really want to turn off”
