The options you want, the performance you demand

You'll love the results you get from the AT4050ST! This innovative stereo condenser gives you the choice of selecting a left-right stereo output or choosing discrete Mid-Side signals for later manipulation. The microphone's dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range. Its transformerless circuitry virtually eliminates low-frequency distortion.

Mid-Side recording capability - from one mic

Because the AT4050ST is equipped with both cardioid and figure-8 elements, it allows you to take advantage of Mid-Side recording techniques; in essence, you can change the "width" of your stereo image to suit a particular project - even after you've recorded! Audio-Technica built the AT4050 to give you a very flexible way to record in stereo, so you can record sources with confidence.

Step up to 40 series quality

Audio-Technica's 40 series microphones let you capture great sound, and they let you do it the way you want. Designed from the ground up for premium performance, these 40 series mics are also built to keep on performing over the long haul - any of the great mics in this series makes a perfect addition to your mic locker! Best of all, these 40 series mics provide top-shelf A-T quality that's suitable for elite studio facilities - at prices that put them well within your reach!
