Boundary Microphones

A boundary microphone lies flat on a table, a lectern or a stage floor and uses that surface as part of its pickup, which keeps it discreet and avoids the problems of a microphone hovering just above a hard surface. Audio-Technica covers both connection types here: the PRO 42 and PRO 44 are cabled models for a mixer, while the ATR4650 and ATR4697 connect over USB for a computer.The main decision is the pickup pattern.
