Overview
The DPA Microphones 3511A is a complete stereo kit with two compact 4011A cardioid microphones with active side cables, carefully factory-matched within ±1 dB on frequency response and sensitivity in the microphone's entire frequency bandwidth.
The first-order cardioid pickup pattern provides superb separation between sound sources when used as a spot mic on literally any style of live music, from rock ‘n' roll to opera. The 4011A is equally suitable for close-up work on acoustic guitar, grand piano, overheads, percussion, wind instruments and vocals as it is for spot-miking symphonies. It can handle incredibly high sound levels.
A flat on-axis frequency response and excellent phase response deliver a totally faithful reproduction of the original sound. The off-axis response is similarly smooth so that any leakage is an accurate reflection of the original, though attenuated according to the true first-order cardioid pickup pattern. The sensation of "being there" will always be more intense with the DPA 4011 than with any other cardioid. Chosen for its qualities as an all-around performer, the 4011 is a great, clean-sounding colorless mic. The variety of applications is as wide as the imagination of the user.
These cardioids are exceptionally linear in their frequency responses - also off-axis. Several standard set-ups such as ORTF and XY are possible. The included XY/ORTF stereo holder makes it possible to fix the two mics in one mount. The 4011A's handle very high SPL and will allow for close-miking as well as more distant placement. They are often used for piano recordings of jazz or pop or overheads for drums. Magnets mounts make it flawless to mount the mics at the piano frame without placing microphone stands.
