BP28L
Line + Gradient Large Diaphragm Condenser Microphone
Audio-Technica combines exceptionally low-noise large-diaphragm condenser elements with a shotgun design for extremely tight polar patterns, perfect for long-range sound recordings. With a length of 56.8 cm, the directional BP28L shotgun microphones have been specially designed to meet the needs of broadcast, film, television, recording outdoors and theater applications. Particularly suitable for long-distance sound recording in filmmaking or in theatre, the BP28L have a very low noise level (3 dB), and a transformer-coupled output results in a smooth sonic character. The microphone provide extremely high sensitivity (-23 dBV), wide dynamic range (135 dB) and high-SPL capability (138 dB). The patented acoustic port design maintains directionality across the entire frequency range.
- Large-diaphragm condenser element and optimized circuitry deliver exceptional low-noise performance – ideal for film/TV production and broadcasting applications
- Overall length of 567.9 mm with an extremely narrow, highly directional pickup pattern
- Transformer-coupled output provides smooth sonic character
- Extremely high sensitivity (-23 dBV), wide dynamic range (135 dB), and high-SPL capability (138 dB)
- Flat frequency response for accurate sound reproduction
- Rugged housing made of lightweight, structural-grade aluminum alloy
- Switchable 80 Hz high-pass filter and 10 dB pad
- Patented acoustic port design maintains directionality across the entire frequency range
