What is a stage-floor microphone?
It is a microphone placed on the floor of a theater stage, usually near the front edge, to pick up actors. It is also called an “area mic” because it picks up over a broad area, as opposed to a headworn wireless mic which picks up only one actor. It’s also called a “foot mic” because it is placed near the footlights, or is called a “safety mic” because it provides a backup in case an actor’s wireless mic fails.
