Mixonline has a very thorough review by Joe Hannigan of the DPA 5100 mobile surround mic.
From dogs playing in his driveway to the 3,200-seat Verizon Hall of the Academy of Vocal Arts’ 75th-anniversary concert, Hannigan is determined to put the 5100 to the test, and concludes:
"As expected with DPA, the 5100 offers one smooth, silky-sounding array that can handle anything you put in front of it. [...] Whether indoors or out, rain or shine, songbirds or opera stars—you can capture it all with the 5100."
