I love my QC, but lately it is driving me insane.
Whenever I power it on (after it has been completely powered down) it boots into this super loud noise (see attached video) - the tuner is going bananas…
After a while it functions as it should… What is wrong here?
Tried different (Neural) power supply, changed ALL cables and factory reset the device - all to no avail… HELP PLEASE!!!
Same trouble happening here…
Now I assume this might be a software bug, not a hardware failure.
I’ve been suffered from this since I updated to CorOS 3.1.0(latest version).
I used to get the same thing until I started leaving it plugged in and manually turn it off and on with the button, maybe it’s something to do with loading the last preset in from a cold boot, the solution could be to just update it to be muted until everything is loaded correctly.

How else would you power it off and on?
Thx for the tipp tough. I have the same feeling (SW defect, not HW). Will try to have it boot into a totally quiet preset - then change manually to the next one (wich is my main tone) after the issue has gone (usually 1-2 minutes).
It´s a workaround tough not an permanent solution - I´d be happy if anyone had a better way of fixing this…
Hey Joe,
Sorry to see that you’re having trouble!

Hi there,
thx for reaching out. Email is sent. I hope to hear back soon.
Regards
I noticed the 3.1 release notes recommend using the power on/off button to power of QC instead of removing the power. There could be something cached that needs to be flushed to the SSD when powering off.
I have never NOT used the power on/off function when shutting down the QC.
Who does such barbaric things to an electronic device?
i’ve been leaving it plugged in and use the power button rather than unplugging and having it automatically power on when it’s plugged back in
the digital distortion sound it makes never lasted more than maybe 10 second for me though switching presets or just loading a different preset when powering on seems to “fix” it
As I use the Quard Cortex in different places (when on tour or playing shows) there is no option of “leaving it on power”. After the show I pack it back in the pelican it mostly lives in…
when the QC was first released, they officially recommended pulling the plug to shut down.
Many users were understandably concerned when they reversed those instructions at the 3.0 manual revision.
That is a horrible idea…
Just stripping any electronic device from power is not good for a device with so many components I assume…
Luckily it seems that Neural has fixed this.
Hey how do they fixed it?
I turn On/Off the device (QC) with the power bottom or the Cortex control power feature into the CC app.
I never pull the plug out the power source.
Remember it’s just like a computer. I assume it need a proper shutdown in order to avoid futur bugs or glitch.
I just wanted to add that I have the same problem on power up. I have to immediately put it in tuner mode so that machine noise doesn’t blow out everybody’s eardrums. The tuner acts berserk during this period.
Once the unit has “warmed up” and the tuner is actually responding to my input, I know it’s safe to take it back out of tuner mode.
I live in a cold climate, and I transport my equipment to practices. I’ve noticed that when the unit is physically cold, it takes longer, eg 10 minutes, in order to “warm up”, before it’s playable.
