    • Audio-Technica AT4050ST PRODUCT 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
