Static Microphone
Neumann tube sound, with cardioid polar pattern and classic M 147 TUBE design
ARTICLE N° 9273
Presentation
The M 147 Tube is a condenser tube microphone with a cardioid pick-up pattern. At the heart of this microphone is a K 47 dual-diaphragm capsule, inherited from its legendary predecessors, the U 47 and M 49.

Behind the capsule is a tube, which acts as an impedance converter. The next stage is an efficient, transformerless output circuit, guaranteeing an extremely low level of self-noise. Note: this innovative combination of tube technology and the most advanced transistor circuits won the neighbouring M 149 Tube a TEC Award in 1997.
The M 147 Tube can use extremely long microphone cables without affecting the quality of the audio signal. Like all Neumann tube microphones, the M 147 Tube comes in an elegant satin nickel finish.
The microphone is supplied in a high-quality aluminium case, with a complete set of accessories: microphone cable, articulated microphone stand and universal power supply. Our modern manufacturing methods enable us to offer this complete set at a very attractive price.
Applications
The famous capsule, enhanced by the characteristics of the lamp, makes the M 147 Tube a microphone well suited to singing. It also makes a superb spot microphone for all types of musical instrument. The clean noise floor of its tube circuitry means it fits perfectly into modern analogue or digital recording chains.
Acoustic characteristics
The M 147 Tube is used vertically, with the sound arriving at the side where the trapezoidal Neumann logo is located. Its black colour identifies tube microphones. The capsule is very similar to that used in the U 47 model, and its influence is decisive in the sonic personality of the M 147 Tube. It has a linear frequency response down to the upper midrange, and a hump above 2kHz, peaking at +3dB. The grille is a smaller version of that on the U 47 model, and effectively protects the capsule from plosives and wind noise.
Directivity
The M147 Tube has a cardioid directional characteristic, which is close to supercardioid thanks to the specific design of its capsule. At high frequencies, the directional pattern becomes more pronounced. This behaviour is very similar to that of the models that inspired this new tube microphone: the U 47 and its successor, the U 47 fet.
Electrical characteristics
Compared with other microphones, the impedance converter used in the M 147 Tube has an extremely low self-noise level: 12 dB (A) / 24 dB CCIR.
Similar to the more recent M 149 Tube model, the new M 147 Tube combines a carefully selected lamp (triode) with modern circuit design. This technique makes the most of the tube's special transfer characteristics, allowing the audio signal from the capsule to pass through to the microphone output without any unwanted coloration or parasitic effects.
The tube amplifies the capsule signal by around 10 dB, avoiding any possible influence on subsequent electronic circuits. The M 147 Tube delivers a high output voltage, and can feed long lengths of microphone cable without signal degradation.
The ideal operating conditions (anode current, heating voltage, etc.) are maintained throughout the life of the lamp. A sensor wire detects any voltage drop in the microphone cable, enabling it to be compensated for at the N 149 A power supply. The temperature of the lamp rises gradually, with the intensity limited in reverse, guaranteeing a long service life.
Filter
The electronic circuitry of the M 147 Tube microphone has a flat frequency response, extending from 20 Hz to well over 20 kHz. Only the attributes of the capsule determine the typical sonic personality of this microphone.
Operational stability
The capsule and all the electronics are mounted on a suspension to prevent any vibrations being transmitted through the body. Thanks to its extended frequency response, the M 147 Tube can reproduce extremely low-frequency signals without any distortion.
As a result, the microphone may be very sensitive to unwanted low-frequency interference, whether from solid-borne transmissions or airflow. To prevent signal degradation, we offer the EA 1 elastic suspension and WS 87 windscreen as accessories. For close miking of a voice, we recommend using the PS 15 or PS 20a pop screen.
