The output of an MS array is not stereo, but rather components (forward fac=
ing mono & a side facing mono mix of left + right, out of polarity.) This r=
aw signal needs to be decoded with an MS matrix in order to derive true ste=
reo, i.e. what was to the left of the mic comes mostly out of the left spea=
ker, etc. I believe the Sony MS mics (relying on 20+ year old memory of usi=
ng these mics,) output decoded Left Right stereo, & do not give you access =
to the raw mid & side components. This is only of importance if you have an=
 interest in altering the width of the decoded stereo signal. With the raw =
MS signal one can adjust the stereo width, from 100% compatible mono, throu=

=E2=80=99s a big deal, though film & video post production mixers seem to l=
