Description
The Audio-Technica BP28L is a high-performance, 22.4-inch (567.9 mm) line + gradient large-diaphragm condenser shotgun microphone designed for professional audio applications requiring extreme directionality and pristine sound quality. It combines a 28mm diameter large-diaphragm condenser capsule with an extended interference tube to deliver an exceptionally narrow, highly directional pickup pattern, making it ideal for long-distance miking in challenging environments.
