    Behringer UM2 white noise when recording/direct monitor with guitar plugged in

    Hello,

    I've bought a new Behringer UM2 for my Taylor Academy 10e to start recording songs and sometime use it with my PC speaker in Direct Monitor mode.

    The issue is, after plugging my guitar in, even when I turn on Direct Monitor or recording in Adobe Audition, there is white noise happening all the time.

    I noticed that when I touch my hand on the cable at the steel part, the noise is gone.

    Can somebody tell me how to remove that noise?

    Many thanks.

    Hi Hiu, welcome to the forum!

    Are you plugging a guitar directly into Input 1 on your UM2? If so then that's probably why you're getting noise on that signal as it's only designed to specifically handle MIC / LINE level signals. Guitars output a instrument level signal, so if that's the case you should be plugging directly into Input #2 on the UMC2, labeled Instrument.

    Please let us know if that helps.

    Hi Michael,
    I did plug my guitar in Inst 2 line, not the first line for Mic.

    Do you have any other idea on where the noise come from?
    Or did I buy a fake one?

    Thanks.

    Ok, then let me ask if you are coming straight out of the guitar directly into the INST2 input on the UM2, or is the guitar feeding a pedal/pedalboard first before the signal hits your interface?

    Another thing to check is to check your gain staging. In short, are you feeding an adequate amount of signal from your guitar (or pedal if used) to the interface or are you having to crank the input knob for that channel very high in order to hear signal? If the guitar signal hitting your interface is on the low side and you are trying to push the INST2 Input volume too hot to compensate then that can potentially introduce unwanted noise into your recorded signal path. (search S/N Ratio on google for more details) It might also be worth trying a different balanced 1/4" instrument cable between your guitar's output and the interface input to see if that helps remove the unwanted noise.

    I'm not able to comment on whether the unit you purchased is potentially "fake" or not, but if it was purchased through one of our authorized retailers worldwide then I'd say that's fairly unlikely. Hoping one of the suggestions above helps you, but if not then please let me know what you tried and what happened as a result.

    Hi Michael,
    Thanks for your detailed answer, a lot of information here since I am just an amateur in recording. But it's quite straight forward.
    I did bring my guitar to the shop to check again and unfortunately, the noise is coming from my guitar pickup itself, not from the cable nor the Behringer.
    And surely, the shop will fix it .
    For the Behringer, I did check the serial via Registration page and it is a good one .
    So, finally the issue was addressed.

    Thanks so much for your help Michael.
    I will post the final result after the pickup is fixed.

    Thanks for replying here with that information. Honestly it hadn't even occurred to me to ask if it could have potentially been coming from your guitar's pickup, but that's definitely something worth checking for this kind of situation. I'm glad to hear that you were able to determine the source of the noise you were experiencing.

    Please let us know how everything turns out.
