Just wondering what this is??? I have heard a few things? And I just wanted to get the real deal???? I have heard that is was 3 mic's in a triangle like left---center---right.... Not sure if thats right. Then I have heard something about come "in-coder" or something that puts all 3 signals together to create a stereo channel? Would like some help if anyone knows?? I'm sure one of you Audio Nuts will. Thanks so much and thanks to all of you for all the great info!!!
