Overview
DPA's 4011A cardioids are exceptionally linear in their frequency response – also off axis, giving you the natural experience. They handle extremely high SPL and will therefore allow for close placement and are often used for piano recordings with a placement closer to the hammers or as overheads for drums.
The DPA ST4011A is a complete DPA 4011A Stereo Pair with two carefully factory-matched first order cardioid microphones. Even though the standard tolerances on DPA Reference Standards are extremely low, a stereo match is even closer.
The specially selected DPA 4011A microphones are matched within ±1 dB on both frequency response and sensitivity.
