  • Bluetooth noise?

    On my Fishman Loudbox Artist, if I turn on the Bluetooth I get this high pitch noise, so I just don't use it. Too bad, but okay, not a problem.

    The problem now is I am now getting it when using the VoicePrint, but I cannot see any way to shut off the Bluetooth on the VP when it is not in use.

    My studio used to be dead quiet, designed with new wiring, grounding, isolation, etc. However, a noise problem started a year ago that I can't track down (not this high pitch noise). Seems to be out there in the Electric Co...very similar to this: [url][/url]

    Maybe this wouldn't happen outside my studio, but I have not had a chance to test it. Moreover, I can't guarantee it won't happen in other less than optimal venues. So some solution would be good (e.g., Hold pad, select and antiFb while standing on left leg and looking up to the left to turn on/off BT).

    Thanks for any insights!

    So there's noise anytime you have the VPDI plugged in? Have you tried a different amp or maybe an audio interface?

    I think it's strange that your Loudbox is picking up noise from its own Bluetooth.

    Do you have any other wireless gear in your studio? Like a wifi router or something?

      Given you've not heard of such a thing before, I sent the VP DI to the DAW and it is still there. So, I would conclude the BT in the VP or BT in the Loudbox (either, it does not matter) is picking up on the yet to be identified noise problem in the studio. Conclusion: Not an LR Baggs problem. Thank you anyway for being part of my process of figuring it all out. Maybe I'll just move :~/

        I've run into my share of mystery noises in my small home studio, but that I ever tied to a Bluetooth signal. That's a strange one.

          I'll show my ignorance in suggesting, BT is 2.4 GHz and there seems to be a lot operating in that range to pick up on. In doing some more searching, there seem to be a number of posts on this "whine."

            2.4Ghz has caused a lot of headaches for audio gear recently, but I've never seen this happen with a fully shielded pedal though.

            It does seem like there are a few other people with this same issue, so I am going to loop our engineers into this and see what we can figure out.

              Solution. Don't know why I didn't think of this before, but using XLR instead of 1/4 output seems to have eliminated the high pitched noise.

                That is odd. Did you try a few different 1/4" cables with it?

                  All sorts, but it does not really matter as I am able to go line level into an acoustic amp. As previously mentioned, I think it is a bigger radio freq prob that started in the area of my studio. No chance to try the VPDI elsewhere yet (Of note, thought something was wrong with my Two Rock amp and the noise disappeared elsewhere)

                  Regardless, I do wonder if a feature to turn off the BT would eliminate the problem in some noisy situations.
