The DPA ST2011A Stereo Pair Twin Diaphragm Cardioid Microphones are part of the Reference Standard Series. Built around the acclaimed DPA 4011 cardioid microphone, the 2011A can be used for multiple applications, and to capture the true stereo field. The ST2011A delivers a blend of clarity, richness and dynamic range. Great for miking and recording on stage and in the studio. Complete with Peli case, holders, and windscreens.

The ST2011A from DPA features a Twin Diaphragm Capsule technology. In a 2011 capsule, two opposite-facing miniature capsules are custom re-built into a double diaphragm, one-capsule composition. The capsules are loaded to the supreme Reference Standard preamps instead of the tiny miniature FET preamp from the miniature mics, offering, even more, air and precision.
