Phantom problem?

    I happened to noitce in the middle of a session that my (phantom powered) B.L.U.E. mouse mic was not working (barely passing signal) when plugged into my VINTECH 1272 preamp. Oddly enough, it seems to work fine on other preamps, (TubeTech, Daking, etc). And also, oddly, other phantom mics like a TLM 103 continue to work fine on the Vintech. I'm assuming that maybe the Vintech is pumping out a little less voltage than some of the others, and the BLUE mouse may be more finicky in it's requirements. So I'm not sure whether blame is with the mic or the preamp (and which one I should be looking to fix). Being a technical ignoramous, can someone tell me if there is an easy way (e.g. using a basic radio shack multimeter) to measure and compare the phantom output off the various preamps? Maybe this will help me pinpoint the problem? I'm leaning towards the mic being at fault, because I read in one review what a hot output it has, and I am finding this particular mic to be very much the opposite.

    Did you try swapping mic cables? You can measure the phantom with a baisc multimeter by checking either pin 2 or pin 3 (depending on which is hot) with ground which is pin 1.

    Cables definitely not the problem. Although half the time my "problem" is something wasn't plugged in.
    Not in this case though. I'll try measuring voltage tomorrow. Yawn, right now I gotta get some zzzz's...

    And can anyone tell me why my smiley's never come out except as URL's?
