    Hi everyone.

    We have the problem with our SQ7, that the console freeze during the mix process. It seems to happen randomly. The only solution to deal with the freeze is to reboot the console. We don’t use the usb connection for multitrack recording but we’re using the RTAs on our EQs. There are a lot of posts about that issue in context to the usb multitrack recording. But we don’t use the usb port so it have to be another problem.

    We have the newest firmware version on the console.

    If you are running the latest firmware, I would not expect it to have anything to do with that bug either.

    If the audio is unaffected, the first thing to check would be any external devices connected that could be causing problems with the control network ‘loop’.
    This could include a USB or network connection to a computer, a router or any devices (tablets/phones/computers) connected wirelessly through a router.
    (I mentioned a bit more about this is a recent stream – https://www.youtube.com/watch?v=tCW681JiAEk&t=2814s – at around the 48min mark)

    A very easy test if you do have a router or computer connected via the network port is to simply unplug it when a freeze occurs.
    The console has mechanisms in it to ignore spurious messaging, but if lots of bad or partial messages are constantly being sent to it, then it can become swamped and freeze up.
    So if unplugging the network connection unfreezes the console, check to ensure that all connected devices have a strong connection and are not dropping out or on the verge of dropping out. Also ensure that any router you may be using has enough bandwidth available for all messaging and that you have followed the usual guidance of hiding SSID and password protecting to ensure you don’t suddenly get lots of connections happening when an audience arrives!

    If this doesn’t point to the issue or help, you can contact us directly using support.allen-heath.com with more details about the whole system and what you were doing when the freezing occurred so we can figure out what happened.
