The ST4011A Matched Stereo Pair of 4011A Cardioid Microphones from DPA Microphones are matched within +/- 1dB on both frequency response and sensitivity to provide accurate sonic reproduction from both mics. They are designed to shine for close placement applications, such as near the hammers of a piano, or as drum overheads. A foam-line transportation Peli case, two windscreens, three pairs of grids, and two mic holders are included.
