The Audio-Technica BP4071 15" Shotgun Line + Gradient Mic is a high-performance line and gradient microphone engineered for broadcasting, film/TV sound, and professional recording applications. This 15.55-inch microphone utilizes an innovative interference tube design to provide the same directivity as microphones up to 50 percent longer, allowing for precise audio pickup in a more compact form factor.
The BP4071 features a direct-coupled, balanced output that ensures a clean signal even during high-output conditions. The transformerless design improves the pickup of transients, while the low noise floor maintains signal integrity for wildlife recording and theater sound reinforcement. This microphone is particularly effective for capturing dynamic action in film and television production or for use in "spot" miking techniques within music studios.
To adapt to various acoustic environments, the BP4071 includes a switchable 80 Hz high-pass filter and a 10 dB pad. The high-pass filter helps reduce the pickup of low-frequency ambient noise, while the pad allows the microphone to handle higher sound pressure levels without distortion. The housing consists of lightweight, structural-grade aluminum alloy, providing a rugged build that withstands the rigors of professional use without adding excessive weight to booms or mounts.
This microphone meets the specialized pickup demands of several professional fields:
The Audio-Technica BP4071 is RoHS-compliant, ensuring it is free from hazardous substances specified in the EU directive. The combination of its lightweight aluminum construction and advanced acoustic design makes it a reliable tool for audio professionals requiring high directivity and clean signal reproduction.
