The DPA Microphones 3511ES Stereo Kit is a complete stereo kit with two compact 4011ES Cardioid Microphones, with active side cables. The mics are carefully factory-matched within ±1 dB on frequency response and sensitivity in the microphone’s entire frequency bandwidth. The kit includes mics, windscreens, holders, clips, and much more.

Ideal for unobtrusive spot miking, such as hanging or table use, the 4011ES Cardioid Microphone, Active Cable is an ultra-compact cardioid microphone from DPA's modular recording mic series. The mic has a length of only 3.5 cm (1.4 in) and a low-key appearance.

The 4011 Cardioid Microphone
The principal appeal of the 4011 Cardioid Microphone is its directional quality and attention to detail. This mic makes everything sounds like the original. The first-order cardioid pickup pattern provides superb separation between sound sources. It's 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.
