Crackling, White noise and fizzling through quad cortex outputs

[frankiebigman]

Hi there!

Recently, my Quad Cortex has been making these noises. Like an intermittent distortion/ white noise, even when I don’t have any effects on. I think its the same problem as what this guy had …

Crackling, white noise, artifacts, fizzing noises

Recently, these noises have been coming up and its frustrating because I play live 3 times a week and have no other pedals/board. Just to cover my bases, I’ve updated to latest os, factory reset, tried different outputs and cables( xlr and ts ), tried different power supplies, different guitars, rebooted, different locations (church and home) this also happens on factory presets Heres a google drive link to see the videos demonstrating the issues Quad Cortex Noises

And also this guy

Unusable due to noise. Crackling, hissing, white noise, volume jumps

CorOS Version: 1.4.1 Describe your issue: So i get this fizzling/volume jump when i either, a) switch scenes or b)stay in the same scene and just press the same scene button……. i don’t know why its doing that. sometimes if i hold down the button and rotate it, it makes noise too. its almost as if the rotary knob is connected to the output? not too sure. I also have a ton of crackling and white noise when I even play clean tones. Steps to reproduce your issue: Turn on QC Play anything I e…

Its very frustrating, as I play 2 gigs a week, and don’t have any other pedals/board. Rely completely on the quad cortex - and its been letting me down lately :/.
Ive been updated to the latest os, Tried different outputs, removed all effect loops and any other pedals. Tried other guitars and even a bass (haha) but its still doing it. I am using the original power supply as well. Its very random and it only happens every once in a while.
Ive already email neural - just wanted to see if anyone else here has had the same problem, and how they have fixed it.
Here is a link to a video of my problem: Quad cortex noise - Google Drive
Thanks so much for your help,
Frank

Similarly to the two threads you linked, your best bet is to email support.

Mine went away for a while but it’s coming back again…. Any luck on yours??

[frankiebigman]

Hi there. i contacted nueral dsp about it. i had to send it back to their factory underwarrenty - it took about 2 weeks to be fixed. Now the problems have away.

Same problem here even tried a factory reset without luck, will have to contact support

Hi Frankie, did you mean the problems have “gone” away after the factory repair? Is the unit still working well after a couple of weeks back with you?

Thanks for the information.

[frankiebigman]

Yes that is the case.

[Stackjammer]

I had the same issues as Frankiebigman. My unit got sent back to Finland, fixed and returned to Australia. So far all is working well. Support from NDSP was good. Hardware issue.

Same issue from South korea last weekend. Preordered unit. After some short contact NDSP support asked to send it back to Finland. Now it is on the transit. Anyone who have the same issue have better to contact NDSP support. I think this is the only and the fastest way to solve this issue.

After having the QC for 10 month now, I experienced the same issue: Sporadic crackling noise on output 1/2, like in the sound example above.

I contacted support and was told to ship my QC back to Finland and that the whole process will take around 2 weeks.

Fingers crossed.

any word on what the cause is?

[alexsa]

Not yet. Support requested reset of settings via A/H stomps during startup.
I have checked cables, environmental stuff, PSU, guitars, speakers etc. before contacting support. After that, I was directly asked to ship in my QC.
Support replied really quick to all my mails within hours.

“and from what we’ve found from previous cases is a malfunction on the board that hosts all of the inputs and outputs.”

[alexsa]

Quote: The issue was related to the connector board, which has been replaced.

If my QC arrives as estimated, the whole process took only 7 days, which is really impressive!

Mine just started doing it as well, white noise and slightly crackly. Happens randomly. The reason why i googled it to see if my problem was isolated. Obviously not

[jackattack]

Have you contacted support about this?
