With directivity equal to mics up to 50% longer, the BP4071 has been specially created to meet the pickup demands of broadcasting, film/TV sound, professional recording, wildlife recording and theater sound reinforcement. Particularly useful for miking dynamic action in film/TV audio as well as in spot miking techniques in the music studio or theater, the 15.55″-long BP4071 provides a low noise floor and direct-coupled, balanced output for a clean signal even in high-output conditions. Audio-Technica has pioneered an interference tube design in the BP4071 that provides the same directivity as mics up to 50 percent longer.Main Features:Designed for use in broadcasting, film/TV production, and theater sound reinforcement applicationsDirect-coupled, balanced output ensures a clean signal even in high-output conditionsInnovative acoustic design provides same directivity as mics up to 50% longerRugged housing made of lightweight structural-grade aluminum alloyTransformerless design for improved pickup of transientsSwitchable 80 Hz high-pass filter & 10 dB padRoHS-compliant free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)Specifications:Element: Externally polarized (DC bias) condenserPolar pattern: Line + gradientFrequency response: 20-20,000 HzLow frequency roll-off: 80 Hz, 18 dB/octaveOpen circuit sensitivity: 29 dB (35.5 mV) re 1V at 1 PaImpedance: 50 ohmsMaximum input sound level: 141 dB SPL, 1 kHz at 1% T.H.D.; 151 dB SPL, with 10 dB pad (nominal)Noise: 13 dB SPLDynamic range (typical): 128 dB, 1 kHz at Max SPLSignal-to-noise ratio: 81 dB, 1 kHz at 1 PaPhantom power requirements: 48V DC, 4.8 mA typicalSwitches: Flat, roll-off ; 10 dB pad (nominal)Weight: 136 g (4.8 oz)Dimensions: 395.0 mm (15.55″) long, 21.0 mm (0.83″) diameterOutput connector: Integral 3-pin XLRM-typeAudio-Technica case style: SG3Accessories furnished: AT8405a stand clamp for 5/8″-27 threaded stands; 5/8″-27 to 3/8″-16 threaded adapter; AT8145 windscreen; two o-rings; protective carrying case
