DPA Microphones 3511A Stereo Mic Kit
The 3511A is a complete stereo kit with two 4011A cardioid microphones, 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 and even includes a 20 dB pad switch in the center of the XLR connector to attenuate the output of the microphone.
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 4011A than with any other cardioid. Chosen for its qualities as an all-around performer, the 4011A 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 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, overheads for drums or orchestra section stereo pair.
