Ground noise-hiss-over all annoyance

I sent mine to neural. I’m also investing in a quality power conditioner.
I’m a big fan of over kill haha

@christopher.mcclella how did this turn out?

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.

Is it normal, that i still have the same problem of hum from the ground with headphone EVEN if my quad is powered by a Cioks DC 7 who have grounded connection… ???

Yes because the CIOKS can’t ground the QC - the QC doesn’t take its ground from the power supply, it floats from the Outputs when connected to other grounded gear

Please Help !

I connect the QC to my MacBook Pro via USB as an audio interface and record guitar tracks for professional arrangements via the Fender Studio Pro 8. I’ve noticed a significant increase in noise, particularly since the latest update. Even though I’m using low levels of gain and drive, close to a clean tone, I hear an electrical hiss and background noise every time I touch the strings to play. Even though I’m using both an input gate and a simple or adaptive gate, I can still hear the electrical crackling mixed with the guitar’s own tone until the gates kick in. I’ve downloaded a huge number of neural captures to find the tones I’m looking for. The memory is almost completely full. I’m wondering if this is having an effect, but I’m not sure. There’s no noise when the guitar isn’t being played. The noise disappears the moment the gate kicks in. But the moment I play a note, I hear a ‘hiss’, ‘hurr’, ‘hum’… I don’t know what to call it, but I hear the notes I’m playing mixed with an electrical background hum. Especially when I hold a single note for a long time, as the note begins to fade, that background noise remains completely, and it stops once the sound ends. I’m looking for a solution to this. It’s affecting my professional career.

have you contacted support@neuraldsp.com yet? If this is a new development, you probably should.

Sounds like a description of electrical background noise, but a sample clip of the issue would help narrow down some possible fixes. Can you provide an audio example of the noise?

(my QC is FULL of captures too, but it doesn’t affect performance)

Hello everyone. I’ve replaced all my cables.

That is to say: I’ve swapped the XLR female to TRS balanced cables for ones from a top-tier brand. I then removed the USB hub I’d been forced to use because of the Qc’s original USB Type B to Type A cable. Instead, I bought a direct USB Type B to Type C cable (I paid a fair bit for these) and I no longer use a hub.

I reset the QC to factory settings. (I took a backup, of course.)

The noise and electrical crackling I was complaining about have decreased significantly (by 85%). It’s now at a very acceptable level. I was able to record comfortably. If anyone else is experiencing this sort of issue, they should invest in the right connection cables. They should prioritise balanced outputs. MacBook users, in particular, should stop using USB hubs. They should pay close attention to the shielding quality of the cables they choose. I’m satisfied for now.

However, I cannot say that my issue has been 100% resolved. I’m open to suggestions for more effective solutions. As I haven’t managed to upload a video here, I couldn’t share the noise clip I was complaining about.

Thank you all very much.
