Great videos - I believe those black plates are outdoor mic used for picking up crowd noise at stadiums and special events. I used to see them when I worked at a local TV station and taped football games. The larger TV stations used them because standard mics would immediately overload when the crowd roars. I remember having to turn off the shotgun mics on our TV cameras because the sound would immediately distort, then the auto controls would kick in and cut the sound completely.
