Frequency response

Angle
Distance

Frequency response: from the manual, p. 8. Free field, IEC 60268-4, tolerance ±2 dB (as printed); relative dB. The legend gives one line for "Fernfeld / Far field + Nahfeld / Near field 20 cm".

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

Polar pattern

Polar pattern: from the manual, p. 8. Free field, IEC 60268-4. 125 Hz to 1 kHz drawn on the left half, 2 to 16 kHz on the right; the pattern is taken as symmetric. 5 dB per ring, centre -25 dB.

Output impedance200 ohm, nominal
Rated load impedance1000 ohm, nominal
Rated frequency range40 Hz to 16 kHz. "Frequenzy response 40 Hz...16 kHz" (sic).
PoweringNM V pattern control unit (mains, 100-120 V / 220-240 V AC, switched automatically). "Connect the microphone only to the included NM V pattern control unit" (p. 5); the NM V "automatically switches between the 100-120 V and 220-240 V ac mains voltage ranges" (p. 6).p. 6
Connector7-pin, to the NM V pattern control unit by the KC 5 cable; XLR-3 output on the NM V. Pin-out and cables on p. 6.
Weight800 g, approx.p. 7
Dimensions80 × 163 mm. Diameter 80 mm, length 163 mm.
Supplied accessoriesNM V pattern control unit; MZ 49 A elastic holder; KC 5 cable (10 m); mains cables (EU, UK, US); transport case. "Delivery includes" and the description of the set (p. 5).p. 5
TubeSelected triode; plate 120 V, ≤ 1 mA; heater 6.3 V, ≤ 200 mA; warm-up approx. 1 minutep. 7
Output transformerBV 11, wound to the original specificationsp. 5
Max. output voltage–8 dBup. 7
High-pass filterFixed, 30 Hz (–3 dB); lowered to 12 Hz with the internal switch S4 (set by Neumann service)p. 5
Cardioid-only modeInternal switch S2 (set by Neumann service): pattern selector inactive, sensitivity ~2 dB higher, equivalent noise ~3 dB lower
Remote pattern controlNM V pattern control unit: the pattern is set on the NM V and is continuously variable; an elevated noise floor for a few seconds after a change while the capsule recharges
Cable length7-core cable to the NM V at most 50 m (else self-noise rises from a too low heater voltage); whole signal path at most 300 mp. 6
Operating conditions0 to +40 °C, 0-75% relative humidity (non-condensing); storage –20 to +70 °C, 0-95%p. 7
Older suppliesThe NM V can power vintage Neumann mics with the AC 701 tube (older M 49, M 249); the old N 52 and NN 48 supplies cannot power the M 49 Vp. 6
