Coincidental - XY or Crossed pairs
Coincidental microphone set ups are where the two microphones’
capsules are set close together on the same axis The most common
of these is XY or crossed pairs In the XY set up, the two microphone
capsules are positioned on the same axis, one directly above the other
with the capsules positioned on an angle from 90 to 120 degrees The
wider the angle, the wider the stereo spread Since the microphones are
set on the same axis, the distance is constant and there’s little or no delay
difference Therefore, the stereo image is created by the level difference
of the left and right microphones Since there is no appreciable delay,
there is less of a chance for phase cancelation and comb filtering so you
can good results when the stereo signal is combined to a mono signal
MS – Mid side
The Mid side technique makes use of two microphones, with one figure-8
and a second mic either cardidod or omni , or two figure-8 pick patterns
The first microphone (the mid), either figure-8, omni or cardioid
microphone, is positioned facing directly at the sound source The second
microphone (the side), with a figure-8 pattern, is positioned on the same
axis directly
