The Audio-Technica BP28L 22" Shotgun Line + Gradient Microphone is a large-diaphragm microphone featuring a 22-inch body designed for professional audio capture.
The Audio-Technica BP28L is a professional large-diaphragm line and gradient microphone designed for high-performance audio capture in demanding environments. This 22.4-inch shotgun microphone integrates a 28 mm diameter body with a large-diaphragm condenser element to deliver exceptional low-noise performance for broadcast, film, television, and theater applications.
The BP28L features a patented acoustic port design that ensures consistent directionality across the entire frequency spectrum. This design allows the microphone to maintain an extremely narrow, highly directional pickup pattern, making it especially suitable for long-distance miking in outdoor recording or theater sound reinforcement. The rugged housing consists of lightweight, structural-grade aluminum alloy to ensure durability during field use.
Equipped with transformer-coupled outputs, the BP28L produces a smooth sonic character ideal for professional film and television production. It provides a flat frequency response for accurate sound reproduction and features an exceptionally low noise floor of 3 dB. The microphone delivers extremely high sensitivity of -23 dBV, ensuring clear signal acquisition even when capturing distant sound sources.
To manage various recording scenarios, the BP28L includes integrated controls for signal optimization. A switchable 80 Hz high-pass filter reduces unwanted low-frequency noise, while a 10 dB pad allows the microphone to handle high-pressure sound sources without distortion.
