    I'm trying to figure out how I can plug an electret condenser stereo mic into my external sound-card. The mic has a male mini stereo (1/8") plug, and the sound-card has the following (female) inputs:
    • Mic (XLR)
      Guitar (1/4")
      S/PDIF (a single RCA in)
      Unbalanced line inputs (pair of 1/4" ins)
    I haven't been able to find any adaptors out there with mini stereo female to XLR male, only the other way 'round, and I'm assuming that a line level input would just give me a tiny, unamplified signal. Not sure if that's also the case for the guitar input though. Thoughts?

    For reference, the mic is a Sony ECM-DS70P, and the sound-card is an M-Audio FireWire Solo.

    Thanks for any and all help!

    Update: I found an adaptor at soundprofessionals
    It's available in a "dual mono" configuration, which, according to the site, sends both channels of a stereo microphone with a miniplug output to the XLR male plug. If that is the case, would my sound-card's XLR input then send a stereo signal into my computer, or would I end up with mono, or half a signal, or something?

    Oi vay...

    I think you'll end up with either the left channel, or possibly the left MINUS the right summed to mono which will totally cut the middle out - you'll basically get nothing except the stuff off to the sides.

    I have had great results from ordering various adapters, Y-cables, etc. from places such as these:

    It won't work directly. That microphone needs "plug-in power", which is 1 - 9V supplied via a resistor of a few K Ohm.

    You can get little battery boxes that house an AA cell into which the mic will plug. The audio output from the battery box can then be taken via a stereo splitter cable to two inputs of your soundcard.

    Here's a page on how to build your own.
