The BP4071L Line and Gradient Condenser Microphone from Audio-Technica features an extended length of 21″ that maximizes directivity and narrows the pickup area. The result is focused audio capturing and minimal noise and artifacts from sources outside the pickup area. The BP4071L is a popular choice among broadcast and film recording professionals, but may also be used in ENG (News Gathering), sound design applications and more.
