Fred,
My reading of the manual for the Sound Devices Mixpre-D is that its only MS=
mode is to decode Mid and Side inputs into Left and Right signals that app=
ear at the main outputs of the mixer. There=92s no option for just doing MS=
decoding in the headphones while passing undecoded MS to the main outputs.
Some of that company=92s other products, such as their 702 and 722 recorder=
s, do offer the choice of decoding just in the headphone output or in both =
mains and headphones.
There are a number of options in DAW software these days that can let you n=
arrow or widen the stereo field of a recorded file. Narrowing is simplest, =
you just have to set the pan controls for each channel to less than full sp=
read. Thus when I record decoded MS in the field I usually set the image to=
be a bit wider than I expect to want, and use the pans to tailor it later.
But widening can be done in software as well. The same process that I descr=
ibed in my earlier note, that converts M and S to L and R, will also conver=
t L and R to M and S! And there are plug-ins that use that kind of under-th=
e-hood math to let you widen the stereo image of a recording. They work for=
decoded MS recordings as well as original LR recordings.

The manual doesn't seem that clear to me.
