Description Offering the realism of a live sound field, the AT4050ST is a side-address condenser with cardioid and figure-of-eight elements Offering the realism of a live sound field, the AT4050ST is a side-address condenser with cardioid and figure-of-eight elements configured in a Mid-Side arrangement. This innovative stereo condenser allows sound recordists the choice of selecting a left-right stereo output or choosing discrete Mid-Side signals for later manipulation, a remarkable flexibility. The microphone’s dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range. Its transformerless circuitry virtually eliminates low-frequency distortion. Features Innovative side-address Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement Independent cardioid and figure-of-eight condenser elements Switch selection of Mid-Side mode and two internally matrixed stereo modes Dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range of the microphone Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics remain constant over years of use Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections Integral 80 Hz high-pass filter switch and 10 dB pad switch State-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards Custom shock mount provides superior isolation Tech Spec Element: Externally-polarized (DC bias) condenser Polar Pattern: Cardioid and Figure-of-eight Frequency Response: 20-18,000 Hz Low Frequency Roll-off: 80 Hz, 12 dB/octave Open Circuit Sensitivity: Stereo 90°: -42 dB (7.9 mV) dB re 1V at 1 PaStereo 127°: -41 dB (8.9 mV) dB re 1V at 1 PaMid: -36 dB (15.8 mV) dB re 1V at 1 PaSide: -36 dB (15.8 mV) dB re 1V at 1 Pa Impedance: 50 ohms Maximum Input Sound Level: Mid and Side: 149 dB SPL, 1 kHz at 1% T.H.D.;159 dB SPL, with 10 dB pad (nominal) Noise: Stereo 90°: 25 dB SPLStereo 127°: 16 dB SPLMid: 15 dB SPLSide: 17 dB SPL Dynamic Range (Typcial): Mid: 134 dB, 1 kHz at Max SPLSide: 132 dB, 1 kHz at Max SPL Signal-to-Noise Ratio: Stereo 90°: 69 dB, 1 kHz at 1 PaStereo 127°: 78 dB, 1 kHz at 1 PaMid: 79 dB, 1 kHz at 1 PaSide: 77 dB, 1 kHz at 1 Pa Phantom Power Requirements: 48V DC, 6.4 mA typical (both channels total) Switches: 90°, 127°, M-S; Flat, roll-off; 10 dB pad (nominal) Weight: 517 g (18.2 oz) Dimensions: 193.0 mm (7.60") long, 53.4 mm (2.10") maximum body diameter Output Connector: Integral 5-pin XLRM-type Cable: 5.0 m (16.5') long, 8-conductor, shielded, vinyl-jacketed stereo cable with 5-pin XLRF-type connector at microphone end and two 3-pin XLRM-type connectors at output end Accessories Furnished: AT8449 shock mount for 5/8"-27 threaded stands; 5/8"-27 to 3/8"-16 threaded adapter; microphone dust cover; protective carrying case Audio-Technica Case Style: R1
