Overview
The DPA ST2011A is a stereo pair with two handpicked cardioid microphones, selected on sensitivity within ±1.5 dB making several stereo principles like XY and ORTF easy to obtain.
Finding its use on numerous stages and recording sessions, the ST2011A exhibits a previously unheard blend of clarity, richness and dynamic range, the 2011As perform close to much more exclusive microphone pairs.
