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.

  • Features

    • Innovative side-address Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement
    • Independent cardioid and figure-of-eight condenser elements

    • 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

AT4050ST is my 'GO TO' Mic!

      Comments about AUDIO-TECHNICA Audio Technica AT4050ST Stereo Condenser Microphone:

      I purchased an AT4050ST because I needed a stereo mic that would be able to give me quality sound in my tracks, but also lots of choices as to what I can do with it. I record vocals and guitar mostly, and it's just sooooo much easier to have a stereo mic that already has stereo modes built into it! I love the fact that you don't need to buy 2 mics that may or may not be figured correctly when you use them in a M/S setting or other. This mic also works excellent as an overhead mic for drums and chorus. There are a few stereo mics out there, but not with the quality like this, AND with Mid-Side and two different degree switches! This is the mic of the future guys! My tracks sound so much more professional! Thank you Audio Technica! You have surpassed all the others! This is my 'Go To' mic for all stereo apps!! Will be hard for anyone to pry this out of my hands!
