Audio-Technica BP28 and BP28L line+gradient large diaphragm condenser microphones

Audio-Technica is launching its new BP28 14-inch (355.6 mm) and BP28L 22.4-inch (569 mm) Line + Gradient Large Diaphragm Condenser Microphones. These microphones combine a large-diaphragm condenser element with a 28 mm diameter shotgun design and low-noise performance. With a patented acoustic port design that reportedly maintains directionality across the entire frequency range, these shotgun microphones are designed to meet the needs of broadcast, film, television, outdoor recording and theater applications.

Particularly suitable for long-distance miking, the BP28 and BP28L offer a highly directional pickup pattern, with the BP28L’s pattern being exceptionally narrow. They provide a flat frequency response and low noise levels (BP28: 8 dB; BP28L: 3 dB) and feature transformer-coupled outputs. High sensitivity (BP28: -28 dBV; BP28L: -23 dBV), wide dynamic range (135 dB), and high-SPL capability (BP28: 143 dB; BP28L: 138 dB), and they are equipped with a switchable 80 Hz high-pass filter and 10 dB pad. Both. The mics’ housing is made of aluminum alloy.
