Frequency response

Angle
Distance

Frequency response: from the response image. Captioned (on the product page) "Typical on and off-axis response of a 2011A microphone. On-axis (0°) measured at 30 cm (11.8 in), other directions measured in the far field." Drawn solid from 50 Hz to about 17 kHz, dotted outside.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the polar image. Captioned (on the product page) "Typical directional characteristics of a DPA 2011A Cardioid Microphone"; 5 dB per ring, centre -25 dB. Measuring conditions not stated. Approximate reading error up to about 1 dB.

CapsuleMMC2011 twin-diaphragm pre-polarised capsule, pressure gradient with interference tube. "Principle of operation: Pressure gradient, with interference tube". The 2012 sheet names the capsule MMC2011 and says two opposite-facing miniature capsules are rebuilt into one double-diaphragm capsule (p. 1).
Sensitivity−40 dBV/Pa (10 mV/Pa), nominal, ±2 dB at 1 kHz. "10 mV/Pa; -40 dB re. 1 V/Pa".
Self-noise20 dB(A), typical; also 23 dB(A), maximum. "Typ. 20 dB(A) re. 20 µPa (max. 23 dB(A))".

"Distortion, THD < 1%: 134 dB SPL RMS, 137 dB SPL peak"; "Max. SPL, THD 10%: 153 dB SPL peak". The 2011C page gives 146 dB SPL peak for THD 10%; the 2012 2011C sheet calls 146 dB "Max. SPL, peak before clipping".
Dynamic range117 dB, typical
Output impedance200 ohm, rated (2011A); also 100 ohm, rated (2011C). The 2011C page gives 100 Ω; the 2012 2011C sheet "< 200 ohm".
Rated frequency range20 Hz to 20 kHz. Effective range ±2 dB at 30 cm: "50 Hz - 17 kHz with 3 dB soft boost at 12 kHz".
PoweringP48 phantom. "Power supply (for full performance): P48 (Phantom Power)"; the 2012 sheet: "48 V Phantom power (± 4 V)".
Current draw2.8 mA
Pad−20 dB, 2011A only. "Switchable attenuator, filters etc.: 0 dB / -20 dB" (2011A; the 2011C page has no such row).
ConnectorXLR-3M (pin 1 shield, pin 2 signal + phase, pin 3 - phase)
Weight164 g, 2011A; also 64, 2011C. "164 g (5.8 oz)"; 2011C "64 g (2.3 oz)".
Dimensions19 × 198 mm. Diameter × length, 2011A: 19 mm (0.75 in) × 198 mm (7.8 in). The 2011C is 19 × 92 mm.

CMRR> 60 dB (2011A); > 50 dB (2011C)
Maximum output voltage, RMS> 5 V (2011A); > 4 V (2011C)
Polarity+V at pin 2 for positive sound pressure
Temperature range-40 °C to 45 °C
Relative humidityUp to 90%
Sensitivity selection tolerance (at 1 kHz)±1.5 dB

Signal-to-noise ratio74 dB, re 94 dB SPL, A-weighted, typical. 2011C sheet: "S/N ratio (A-weighted), re. 1 kHz at 1 Pa (94 dB SPL): Typ. 74 dB(A)".p. 2
Rated load impedance2000 ohm, minimum. 2011C sheet: "Minimum load impedance: 2 kohm".
Finishmatte black. "Color: Matte black".
Versions2011A (MMP-A preamp: "low distortion and total accurate and faithful sound"), 2011C (MMP-C compact preamp: "a bit more body to the low end"), 2011ER/ES (with rear or side cable); stereo pair ST2011Cp. 1
Use"primarily optimized for on-stage use": linear off-axis response over a narrower band than the 4011, for stage separation and gain before feedback
