I just don't see the need for micing a marching band. You should be judged by your band, not your sound man.
You'd be shocked. Most big school marching bands have better technology then their theaters. I've seen schools
roll up with 40 of the
Shure UHF-R pro wireless mics (their whole pit was mic'd up wirelessly, as well as solos and other insruments throughout the field), complete with
paddle antennas and distros. All hooked up to a digital board, routed over a wireless
network to laptop/iPad in the stands. It's a whole new ball game....
Of course, with these big name high schools being sponsored by Yahmaha,
Shure,
etc, it's not so hard to believe they have this money...
Just like everything else in today's society, if technology can improve it, then use it. It allows for greater flexibility. You want to put the pit in the back of the field instead of traditionally in the front, you can do it now. You want your little flute solo to be heard over the blaring brass, you can do it. If you have a band with 30 trumpets and 10 clarinets, mic up a few clarinets to get that woodwind feature heard.
It gives the directors and artistic designers more freedom and flexibility. Gone are the days of traditional marching band, only a few colleges and drum corps do that now. And don't even get me started on the over use of
props on the fields....
