DPA ST2011C Twin Diaphragm Cardioid Stereo Pair

Product Overview
Matched stereo pairs
The wide and versatile d:dicate™ Microphone series is legendary in the high-end recording and film production industry. Delivering clean, accurate sound, the mics in this series are used by professionals, who understand sound and insist on only using the best.

We have collected our award-winning d:dicate™ Recording Microphones in specialized stereo pairs that are matched within either ±0.5 dB, ±1 dB ±1.5 dB, depending on the pair you choose. Explore the stereo pairs below.

2011 Cardioid Stereo Pair
This complete stereo pair contains two handpicked d:dicate™ 2011 Twin Diaphragm Cardioid Microphones, selected on sensitivity within ±1.5 dB. These mics make several stereo principles like XY and ORTF easy to obtain. The pair contains mics, windscreens and clips all packaged in a Peli™ Case.

The 2011 Twin Diaphragm Cardioid Microphone
Inside the 2011 Twin Diaphragm Cardioid Microphone, two opposite-facing miniature capsules are custom rebuilt. They are placed into a double-diaphragm, one-capsule composition. This combines the advantages of small capsules with the lower inherent noise achieved from a larger diaphragm area. These capsules provide fast impulse response and large frequency bandwidth.

Inside the MMC2011 Twin Diaphragm Cardioid Capsule, two opposite-facing miniature capsules are custom rebuilt. They are placed into a double-diaphragm, one-capsule composition. This combines the advantages of small capsules with the lower inherent noise achieved from a larger diaphragm area. These capsules provide fast impulse response and large frequency bandwidth.

The capsules are loaded to the supreme d:dicate™ Microphone series preamplifiers instead of the tiny miniature FET ones. This gives the sound more air and precision.

ST2011C Stereo Pair
Together with the MMP-C preamp, this makes a small, lightweight and inconspicuous stereo pair.

The compact design and controlled directionality of these mics make them an excellent choice for spot mics for classical recording and on-stage close mics for live sound. Features • Modularity – interchangable capsules and preamplifiers
• Up to 120 dB dynamic range
• RF rejection between >60 and >40 dB
• Linear frequency response
• High SPL
• Superior gain before feedback
