Audio Technica AT4050ST

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.

• 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)
