Product overview
The DPA ST4011A is a matched stereo pair of 4011A Cardioid Microphones, matched to ±1 dB in frequency response and sensitivity, with a phase deviation below 10° for the kit.
The 4011 is renowned in recording studios and live applications around the world. State-of-the-art components have been carefully selected to provide optimal neutrality, accuracy and extremely low distortion. The principal appeal of the 4011 is its directional quality and attention to detail: it makes everything sound like the original. The first-order cardioid pickup pattern provides superb separation between sound sources, and it can handle incredibly high sound pressure levels. A flat on-axis frequency response and excellent phase response deliver a faithful reproduction of the original sound; the off-axis response is similarly smooth, so any leakage is an accurate reflection of the original, attenuated according to the true first-order cardioid pattern.
The 4011A is equally suitable for close-up work on acoustic guitar, grand piano, overheads, percussion, wind instruments and vocals, as well as spot-miking symphonies. Each microphone includes a 20 dB pad switch in the centre of the XLR connector, runs on P48 phantom power and has a balanced output with Active Drive.
