link to mic specsthose are the specs on the mic. It is described as a Mid Side mic, but also unidirectional? Some one please help me understand how this thing works. It also has a switch between 90 and 120 degrees, I'm actually not sure what that does now if there are 2 caps in there. I always figured there were 2 caps postioned x/y and you can vary the angle, but every site I've been reading says it's a mid-side and I'm just not understanding it
