Audio-Technica AT4050ST

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. +4 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 Certified by the METAlliance (Music Engineering and Technology Alliance) Specifications Microphones Element Polar Pattern Frequency Response Low Frequency Roll Off Open Circuit Sensitivity Maximum Input Sound Level Noise Dynamic Range Signal-to-Noise Ratio Phantom Power Requirements Switches Weight Cable Dimensions Output Connector Accessories Included Audio-Technica Case Style
