    I have an MKE300 mic, and I want to hook it up to an M-Audio MobilePre
    USB box which connects to my laptop.

    The MobilePre has five inputs:
    - 1/8" stereo mic level
    - 2 1/4" mono balanced high-impedence line level
    - 2 XLR mono balanced mic level

    I want to connect the MKE300 which has a 1/8" mono plug to the
    MobilePre, which is about 20' away. I am very new to audio
    technology, and am learning as I go. From what I've read, over long
    distances, interference is a concern, and balanced XLR is supposed to
    be the remedy. So from what I can tell, the best solution is to get
    some sort of adapter to convert the 1/8" mono to balanced XLR, then
    get a balanced XLR cable to run the distance.

    My questions are:

    1. Is this the best solution?
    2. If so, what kind of adapter do I need?
    3. If not, what is the best solution?

    Don't confuse balanced with XLR. They're two separate things.

    The only external way you could balance that mic is with a powered opamp
    circuit or a transformer. (You possibly could balance it internally, if
    you're handy with small electronics.)

    Youre best bet is to plug the mic directly into the MobilePre, using its
    (what, about 2'?) cable. Then run a line-level cable to the camera.

    Barring that, you can run 20' unbalanced with good cable... but be careful
    to route away from power, timecode, and video lines.
