DPA 2011A Twin Diaphragm Cardioid Pencil Microphone

The 2011A Twin Diaphragm Cardioid Microphone is acclaimed for its close-miking excellence and hi-SPL handling.

The 2011A Twin Diaphragm Cardioid Microphone is part of the flexible Microphones Series. It combines the MMC2011 Twin Diaphragm Cardioid Capsule with the MMP-A preamplifier. This combination is for the true audiophile. It offers low distortion and totally accurate and faithful sound.

Where to buy

Product Description

The 2011A‘s cardioid polar pattern makes it great for live recordings too, and as well as in studio it is often used on stage. It exhibits a previously unheard blend of clarity, richness and dynamic range and its capsule (either with ‘C’ or ‘A’ pre-amp) is fast becoming a standard snare, kick drum and overhead miking stalwart.

The off-axis response is linear but in a smaller frequency bandwidth. This makes stage separation and gain-to-feedback higher. The mic level is easier to control.

The 2011 microphone capsule:

Inside this capsule, two opposite-facing miniature capsules are custom rebuilt. They are assembled into one double-diaphragm, single-backplate 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 benefit from the supreme quality of DPA’s PEncil series preamplifiers instead of the usual miniature FET pres. This gives the mic much more headroom and the sound more air and precision.

Comparisons with its big brother, the iconic MMC4011 capsule, are inevitable. The relationship between the two can be clearly heard. The MMC2000 series performs as well as more exclusive microphones. It is a premium-class mic capsule and redefines the term value for money.
