While I do think that in post the m/s will give you the most options for fine tuning your mix, but by adding two more mics flanked/spaced, it will make the ability to "control" the m/s kinda useless IMO. I love the tight center that m/s (xy) produces onstage, and I would think that adding two mics spread on either side would give you a great addition to the mix. If it were me, and I realized that I had control of the levels of the two spread mics in the mix, I would run x/y in the middle with the ld's. Why control the "s" of the m/s mix when you can do it with two flanked mics?
R U talking about putting each 482 10 feet from the center L and R? if the stage is 20feet wide, Id say go 7 or 8 feet left and right of the center TL's with the 482's and run xy with the TL's.. This will give you the ability to mix in the two flanked mics to taste, while still have a good center image.
M/S really shines onstage. You have tremendous control over the stereo imaging of the final mix.
absolutely! I love m/s as a single pair.. great imaging, distance clues AND control.. but with two added mics on each side, I think your putting in too many variables for post mix..
all this if ya wanna keep it simple.. feel free to run the TL's in m/s and Im sure youll get good results, but it might just be TOO many variables to achieve the same results with xy..
ymmv of course..
