Based on models originally developed for use in the broadcast of the Sydney Games in 2000, the BP4027 (14.96″ long) and BP4029 (9.29″ long) Stereo Shotgun models are engineered for high-end broadcast and production use. Both microphones feature independent line-cardioid and figure-of-eight elements configured in an MS (Mid-Side) arrangement with switch-selectable internal matrixing. These innovative microphones allow sound recordists the choice of selecting a left-right stereo output (wide or narrow) via the microphones internal matrixing system or choosing discrete Mid-Side signals for later manipulation, a flexibility not available from any other manufacturer.A switchable low frequency roll-off filter helps minimize the pickup of unwanted low frequency noise. These phantom-powered models feature a rugged lightweight design and sleek black color scheme, perfect for on-camera use.Main Features:Designed for broadcasters, videographers and sound recordistsCompact, lightweight design is perfect for camera-mount useIndependent Line-cardioid and Figure-of-eight condenser elementsSwitchable low-frequency roll-offSwitch selection of non-matrixed M-S mode and two internally-matrixed left/right stereo modesIncludes a 0.61 m (24″) cable (5-pin XLRF to two standard 3-pin XLRM connectors)RoHS compliantfree from all substances specified in the EU directive on hazardous substancesSpecifications:Element: Fixed-charge back plate, permanently polarized condenserPolar Pattern: Line-cardioid, Figure-of-eightFrequency Response: 40-20,000 HzLow Frequency Roll Off: 80 Hz, 12 dB/octaveOpen Circuit Sensitivity: Mid: -30 dB (31.6 mV) re 1V at 1 Pa; Side: -34 dB (19.9 mV) re 1V at 1 Pa; LR Stereo: -36 dB (15.8 mV) re 1V at 1 PaMaximum Input Sound Level: Mid: 123 dB SPL, 1 kHz at 1% T.H.D.; Side: 127 dB SPL, 1 kHz at 1% T.H.D.; LR Stereo: 126 dB SPL, 1 kHz at 1% T.H.D.Dynamic Range: Mid: 101 dB, 1 kHz at Max SPL; Side: 101 dB, 1 kHz at Max SPL; LR Stereo: 102 dB, 1 kHz at Max SPLSignal-to-Noise Ratio: Mid: 72 dB SPL, 1 kHz at 1 Pa; Side: 68 dB SPL, 1 kHz at 1 Pa; LR Stereo: 70 dB SPL, 1 kHz at 1 PaPhantom Power Requirements: 11-52V DC, 4 mA typical at 48V, each channelSwitches: M-S, LR Stereo-Wide (LR-W), LR Stereo-Narrow (LR-N); Flat, roll-offWeight: 103 g (3.6 oz)Cable: Dual 0.61 m (24″) shielded two-conductor, terminated in two XLR3M-type connectorsDimensions: 236.0 mm (9.29″) long, 21.0 mm (0.83″) diameterOutput Connector: Integral XLR5M-typeAccessories Included: AT8405a stand clamp for 5/8″-27 threaded stands; AT8134 foam windscreen; 5/8″-27 to 3/8″-16 threaded adapter; two O-Rings; protective carrying caseAudio-Technica Case Style: SG2
