Microphones in Broadway Plays - WSJ.com
On stage at the Broadway revival of Neil Simon's "Brighton Beach Memoirs" are seven actors—and 23 hidden microphones. The new musical "Fela!" has 80 speakers hung around the theater, and mic transmitters embedded in a character's tap shoes. And during one song in "The Phantom of the Opera," actors choose whether to sing along—or just mouth the words—to a prerecorded vocal track.
