High pitched noise with 3DIO XLR

  • E

    Hi! I'm at my wits end trying to figure out what is going on with my microphone. Please help.

    I was using the XLR with 48v phantom power turned off, because I upgraded from a 3DIO FS and didn't realize I needed to turn that on for it to sound a lot better and not need to boost the gain so much. However, I've occaisionally been getting this really high pitched noise coming in and out since switching phantom power on. I tried brand new XLR cables because I thought that may be the issue, I also tried plugging the audio interface into a different PC to see if it was an issue with my PC but the issue persisted. I tried unplugging all my electronics, tried without headphones to see if it was some kind of interference but the issue persisted. Please let me know what else I can do, or if it's an internal mic issue if I can get a replacement mic. Thank you so much.

    Hi @EY,

    Thank you for reaching out to us. So sorry to hear you're getting a high pitch noise.

    Can you please send us an audio clip of the noise so we can hear what you're hearing?

    Do you hear the same high pitch noise when using the 3.5mm TRS output? or only using the XLR outputs?

    Any additional information you can provide would be helpful.

    Best regards,
    ~Brian

    Here is a link to a clip: https://drive.google.com/file/d/1uoPPwNuBA_sxw4x6dc2CoZ2eXfAqCXF7/view?usp=sharing

    I do not hear the noise when using the 3.5mm TRS outputs, but the input is incredibly quiet and muffled and I can't record like this. I tried phantom power both on or off. Let me know if there's any other info I can provide!
