The BP28 combines a large-diaphragm condenser element with a 28 mm diameter shotgun body for exceptional low-noise performance.With a highly directional pickup pattern and a patented acoustic port design that maintains directionality across the entire frequency range, this 14″ shotgun microphone is specially tailored to meet the needs of broadcast, film, television, outdoors recording and theater applications. Particularly suitable for long-distance miking for film or theater, the BP28 has an exceptionally low noise floor (8 dB) and transformer-coupled outputs that produce a smooth sonic character. The microphone also provides extremely high sensitivity (-28 dBV), wide dynamic range (135 dB), and high-SPL capability (143 dB), and is equipped with a switchable 80 Hz high-pass filter and 10 dB pad.Main Features:Designed for use in broadcasting, film/TV production, and theater sound reinforcement applicationsOverall length of 14″ with a highly directional pickup patternThe custom 28 mm diameter shotgun body houses a large-diaphragm condenser element for exceptional low-noise performanceTransformer-coupled output provides smooth sonic characterExtremely high sensitivity (-28 dBV), wide dynamic range (135 dB), and high-SPL capability (143 dB)Flat frequency response for accurate sound reproductionRugged housing made of lightweight, structural-grade aluminum alloySwitchable 80 Hz high-pass filter and 10 dB padPatented acoustic port design maintains directionality across the entire frequency rangeSpecifications:Element: Fixed-charge back plate, permanently polarized condenserPolar pattern: Line + gradientFrequency response: 20-20,000 HzLow frequency roll-off: 80 Hz, 18 dB/octavePad: -10 dBOpen circuit sensitivity: -28 dB(39.8 mV) (0 dB=1 V/Pa, 1 kHzImpedance: 250 ohmsMaximum input sound level: 143 dB SPL (1 kHz at 1% THD), 153 dB SPL (When pad is on.)Noise: 8 dB SPL (A-weighted)Dynamic range (typical): 135 dB (1 kHz at Max SPL)Signal-to-noise ratio: 86 dB (1 kHz at 1 Pa, A-weighted)Phantom power requirements: 11-52 V DC, 3.4 mASwitches: Low cut: on/off, Pad: on/ofWeight: 223 g (7.9 oz)Dimensions: 354.9 mm (14.0″) long, 28.0 mm (1.1″) maximum body diameterOutput connector: Integral 3-pin XLR-M typeAudio-Technica case style: SG6Accessories furnished: Windscreen (AT8170), holder (AT8470), stand adapter (“-“)
