Meet the Audio-Technica AT4050 studio condenser that captures every nuance. With three switchable polar patterns, the large-diaphragm Audio-Technica AT4050 exhibits a remarkable combination of qualities: high-SPL capability with transparent and airy uppers/mids complemented by rich low-end qualities. Its dual large diaphragms are gold-vaporized and aged for consistent, outstanding performance. A precision-machined, nickel-plated brass acoustic element baffle provides rock-solid element stability and exceptional sensitivity.Features: Transparent uppers/mids balanced by rich low-end qualities combine with advanced acoustic engineering for extensive performance capabilities and highest quality Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone The 2-micron-thick, vapour-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use Three switchable polar patterns: omni, cardioid, figure-of-eight Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards Switchable 80 Hz hi-pass filter and 10 dB pad Custom shock mount provides superior isolation Specifications: Element: Externally-polarized (DC bias) condenser Polar Pattern: Cardioid, Omnidirectional, Figure-of-eight Frequency Response: 20-18,000 Hz Low Frequency Roll-Off: 80 Hz, 12 dB/octave Open Circuit Sensitivity: -36 dB (15.8 mV), re 1V at 1 Pa Impedance: 100 ohms Maximum Input Sound Level: 149 dB SPL, 1 kHz at 1% T.H.D.; 159 dB SPL, with 10 dB pad (nominal) Noise: 17 dB Dynamic Range (typical): 132 dB, 1 kHz at Max SPL Signal-to-Noise Ratio: 77 dB, 1 kHz at 1 Pa Phantom Power Requirements: 48V DC, 4.2 mA typical Switches: Polar selection; Flat, roll-off; 10 dB pad (nominal) Weight: 18.0 oz (510 g) Dimensions: 7.40" (188.0 mm) long, 2.10" (53.4 mm) maximum body diameter Output Connectors: Integral 3-pin XLRM-type Accessories: AT8449a shock mount for 5/8"-27 threaded stands; microphone dust cover; protective carrying case Case: Style R1
