The Audio Technica AT4050ST Stereo Microphone is a stereo side-address condenser microphone with independent cardioid and figure-of-eight elements configured in a Mid-Side arrangement with switch-selectable internal matrixing. It is perfect for professional recording, broadcast and sound reinforcement.

The Audio Technica AT4050ST Stereo Microphone offers the realism of a live sound field. 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.

What We Think

"Audio Technica hits yet another home-run with the AT4050ST. Long used in pairs for overhead drums both live and in the studio, the AT4050 remains a favorite microphone for it's distinctive character that is also at the same time natural. The AT4050ST makes for a wonderfully compact solution for those seeking to capture truly professional stereo recordings (made with truly professional gear) with a minimum of fuss when tracking... and a maximum of flexibility at mix down. Mid-Side is excellent for allowing you to adjust the narrowness and/or width of your stereo field when mixing. Truly a great choice as a room microphone!"
