Good afternoon. Tell me. I have a nano cortex. I wanted to use the left exit to connect to the babyface pro fs card. But it has an unbalanced input for tools. The balanced ones are occupied by microphones. As a result, when the mono jack is connected from the nano cortex to the card, I hear a strong background. The ground switch helps, but not much. I know that the nano cortex outputs are balanced. How can this problem be solved? Moreover, the older quad cortex brother does not provide a background. Who faced the problem, is there a solution?
At least from my experience, the Nano Cortex is significantly quieter and less noisy than the Quad Cortex.
At least when taking Captures, I sometimes need a Morley Hum Eliminator to reduce hum. Perhaps that could help your issue?

With active pickups, there is no noise on the guitar. There are passive ones. You need a grounded power supply, then there will be no noise. And away from electrical appliances.
also make sure your power supply delivers a minimum of 500ma. I had the same issue until I realized my power supply only delivered 200. Once I swapped it out to a power supply that cranked out 500ma, noise was gone.
Also, be sure you you aren’t connected via usb and using outs to an AI otherwise you will get a ground loop

Hi! I had same issue while using small size power adaptors. After using it with 12V power adaptor from old laptop (wires flipped) it works fine. Small adaptors create noise. But never tried it connected to other devices, true negative powered device connected to NC may have an issue( due to wires just being flipped and not supplying real negative voltage) good luck!
