Just to be clear on this, measurement mics are (supposed to be) omni-directional and will record the same thing no matter which way they point (almost - 95%+ there is always a slight effect from the mic body stem that holds the capsule). Your results are fascinating and bizarre... so your Behringer is not really omni pattern?... hmmm... Something seems not right to me. ... Your results seem indicative of a faulty circuit board inside the mic, with one "phase" (side) of the capsule circuit not working properly so its polar response is asymettric. I've had all sorts of bad experiences with Behringer gear... probably best I don't go into details :-( -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
