Multi-pattern Condenser Microphone 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. Ideal for studio use and live sound productions with vocals, piano, strings, drum overheads, guitar amps, and more. 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, vapor-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 ELEMENT Externally-polarized (DC bias) condenser POLAR PATTERNS 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 FURNISHED AT8449 shock mount for 5/8"-27 threaded stands; microphone dust cover; protective carrying case AUDIO-TECHNICA CASE STYLE R1
