I’m not understanding what’s happening… I have ground/USB noise/whine on the track my Sub37 is connected to.
I have a fairly complex setup. A Xone 96 with my synth and gear plugged in. The Xone goes to a UCX RME pair of audio inputs, and the UCX is connected via USB to the computer.
Now, only on the Sub37 track do I get this annoying noise. Even when it is not connected via USB to the computer. All other tracks, synths (a M, OB6, Nord Drum 3P, Syntrx, Digitakt) are clean. I tries turning everything OFF but the Sub37, Xone and UCX, I still get the noise.
I tried using another input pair on the Xone for the Sub37, same. So it’s not coming from the Xone channel.
Any idea? Would their be a ground/earth issue with the Sub37?
Sounds obvious but start at the xzone with a pair of headphones if poss. Unplug everything and start with just the sub37 plugged in. Can you hear noise in the headphones? If not then plug the xzone into whatever comes next in the chain then finally the computer checking as you go. Process of elimination
Berlin Germany. I have a ground, is it good, no idea.
Having the headphones plugged into the Xone, no sound goes through the UCX, but if I disconnect the USB cable going into the UCX, the noise is gone. Meaning that the noise definitely comes from the computer through that USB cable, and travels through the audio cables.
The mystery is, why only on the track of the Sub37…
I suspect the sub37 is the only thing you’ve got going into the xzone with a direct earth connection. Stuff fed by wall warts/external PSU’s is inherently isolated from mains earth wiring. If that’s the case you could try a Di box with ground lift between the sub and the xzone input.
If the above conditions are met you could well have a ground loop problem
There’s got to be something going on with the sub tho as you say, every other channel is silent which would discount the usb cable itself otherwise there would be noise on all channels? Can’t see a ferrite sorting that out?
