Ah too bad. Then it’s probably really time to contact NeuralDSP and send your QC to them.
I wish I could show you a video of the sound. It’s super unfortunate to have to go through all that. But you’re right. I may be stuck otherwise
I have the same problem
I sent mine to neural. I’m also investing in a quality power conditioner.
I’m a big fan of over kill haha
I worked with Sweetwater. They were immensely helpfu. They replaced my quad entirely with a new one.
Annnnnd….i still have the noise lol
Have you tried:
Turning the computer monitor(s) off? At least long enough to test.
Flipping the ‘Ground Lift’ switches on input 1/2 on the swipe-down I/O page?
Cabling the QC into a grounded FRFR or amp?
Moving it to other outlets?
Do you get noise when you use your QC outside of your home?
Have you searched for sources of noise in your home? Unplug anything you can and turn all other devices off including your phone, lights, computer, etc., and see if the noise disappears. If you have access to a fuse box, you can try turning other breakers off while testing QC. Also try plugging QC in on different breakers to test while the others are off.
