Offering the realism of a live sound field, the AT4050ST is a sideaddress condenser with cardioid and figureofeight elements configured in a MidSide arrangement. This innovative stereo condenser allows sound recordists the choice of selecting a leftright stereo output or choosing discrete MidSide signals for later manipulation, a remarkable flexibility. The microphones dualdiaphragm capsules maintain precise polar pattern definition across the full frequency range. Its transformerless circuitry virtually eliminates lowfrequency distortion.
