I have a recurring issue with my Quad Cortex. Regularly, no sound comes out at all. I’ve thoroughly checked the input/output levels, etc. I notice that the tuner works correctly, however no guitar sound comes out, either through my cab or through my headphones, and when I play guitar, there is no input signal LED activity at all.
I also connected the QC to my Mac to use it as an audio interface, and that doesn’t work either (I’ve correctly configured my Mac’s output settings).
I recently ran into this issue right before a show. I powered it off and restarted it several times, and it eventually started working just a few minutes before the show.
Is this a known and identified issue on your end? Has someone already experienced that?
Hi I’ve had this also but whether it’s the same thing I don’t know! But do you have a midi controller connected to the QC and I have to wakeup the controller and make sure it’s in stomp mode or whatever tap a button and then the expression pedal works and the volume works… But I do have signal reading on inputs and outputs just no sound until I get the board setup type of scenereo
Thanks for the interest. I don’t have any midi controller connected. It works perfectly … until it stops working ! And a few days later it works again.
Are you using the OEM power supply? If not, what PS are you using? These output issues have been known to stem from power supplies in the past or as @xush stated, worst case it could be a defective I/O board. Have you tested to see if USB audio works? Example, do you have the ability to test using a cell phone playing a backing track or any audio?
I agree, contact support@neuraldsp.com to determine the issue. Hopefully a factory reset will resolve but it’s best that support logs the issue and guides you through the necessary diagnostics including a factory reset or next steps if needed.
Hello, I’ve also the same problem randomly.
Excatly same symptom :
No sound at any outpout
Input 1 work (tuner)
Output 1 level on settings screen display output
A restart can solve the problem, but if you didn’t have time while giging can cause a really inconvenient situtation
It’s not a hardware problem if we have same issue
