Summary of the Test 👇

If you are a fan of the Neumann brand, you will certainly like to add the M149 to your collection. This is a tube condenser microphone known for its versatility. But what about its sound quality? Is this microphone really exceptional on all types of sound sources ? To confirm this, what better way than to test the microphone. Here is the complete review of the Neumann M149 microphone.

Focus on the Neumann brand

Neumann is a company founded by Georg Neumann in 1928. This German brand specializes in the design of audio equipment . Among others, we can cite professional studio headphones , speakers and microphones.

This manufacturer owes much of its reputation to the quality of its high-end studio microphones . The most successful in this category is undoubtedly the Neumann U47. Elvis Presley, Amy Winehouse, Stevie Wonder, Aretha Franklin… all these legendary artists have already used this legendary microphone.

During its 90 years of expertise, this German brand has continued to bring innovations to the world of audio recording. Among the most notable, we can note the invention of the first phantom-powered microphone in 1966: the legendary KM84 . Another innovation from this renowned brand: the TLM170, the very first transformerless microphone on the market.

Note that Neumann has a vast catalog of microphones classified into several categories. It notably offers microphones for singing, USB microphones , and condenser microphones which are available in small and large diaphragms.

In this article, we will focus on a condenser microphone with a large diaphragm tube : the Neumann M149. Let's review the strengths and weaknesses of this high-end studio microphone.

Neumann M149 Microphone Overview

Neumann M149 is a large diaphragm condenser microphone like its friend, the Neumann M147 . As its name suggests, this type of microphone has a condenser. The role of this is to transform the charge into an electrical signal. The latter will then be amplified and transmitted to the sound card or amplifier.

As this is a tube microphone , phantom power is not required to operate it. However, you will need the external power supply that comes with the mic.

Like the M147, the M149 is equipped with the same capsule that was in the famous original U47 as well as the M49. Its particularity: it is a double membrane capsule . To this device is added a lamp whose role is to convert the impedance. This model is also distinguished by its transformerless circuit .

Result: absence of coloring even if you use long cables. Moreover, according to the German manufacturer, you can use cables up to 300 m long without worrying about signal degradation.



Neumann M149 benefits from the same design quality as the M147. Among other things, its finish is satin nickel. In addition, on the front side, we still find the Neumann trapezoid logo. However, there are some differences between these two models.

Indeed, on the front of the M147, we find an inverted heart to refer to its polar diagram. On the other hand, given that the M149 offers 9 directivities , this model displays other symbols linked to the polar diagrams of each directivity. For the 4 intermediate directivities, we only find points.

Another difference between the M147 and the M149 is in terms of weight. In fact, these two condenser microphones weigh 460 and 730 g respectively. So provide a sturdy enough foot to hang the M149 since it is not designed to be held by hand. Furthermore, with its 70 mm in diameter and 201 mm in length , the Neumann M149 is more imposing than the M147.

As for accessories, by purchasing the Neumann M147, you will be entitled to:

  • An N 149 A power supply to operate the microphone
  • An aluminum case to carry the microphone when traveling
  • An 8-pin mic cable to connect the mic to your device
  • An EA170 elastic suspension to effectively isolate handling noise
  • A storage pouch to prevent dust when you are not using the microphone

Neumann M149: a tube microphone with 9 directivity

Neumann was the first large diaphragm microphone to offer a switchable polar pattern. We are of course talking about the legendary Neumann U47 FET , and original U47 with its two directivities to choose from: cardioid and omnidirectional.

With the Neumann M149, this brand impresses us once again. In fact, this model has 9 directivities:

  • Cardioid polar pattern : to capture sounds coming from the front of the microphone
  • Wide-angle cardioid polar pattern
  • Omnidirectional directivity : to capture sound sources in the room uniformly
  • Hypercardioid polar pattern : a variation of the cardioid polar pattern to accentuate the sensitivity of the microphone towards the rear
  • Bidirectional directionality : to capture sounds coming from the front and back of the microphone
  • And an intermediate option between each main directivity for even more precise sound recording

Placed on the front of the microphone, the slide switch allows you to easily switch from one directionality to another.

M149: a versatile microphone model

Obviously, the fact that the Neumann M149 has 9 directivities is not without consequences on the use of the M149. Indeed, its 9 directivities to choose from make this microphone a versatile model .



Thanks to this ability to switch between these options at any time, this model can be suitable for both vocal recording and acoustic instrument recording . You can use it in particular to record your acoustic guitar, your piano, your violin, the overheard of your drums and many other acoustic instruments.

However, you must know how to choose the directivity to activate depending on the use of the microphone. For example, if you want to record the voices of two people located on either side of the microphone, simply opt for the directionality in figure 8 .

For choir voice recording, a lecture, or other applications that require capturing the ambience of the room, enable omnidirectional polarity .

If you want to record just one person's voice, all you have to do is activate the cardioid polar pattern and that's it.

As for stereo sound recording , again, be sure to choose your directionality wisely. For example, if you want to use the M149 as a side mic when recording with the Mid-Side technique, you must opt ​​for the figure 8 polar pattern . On the other hand, if you want to use it as a Mid microphone, you must choose the cardioid polar pattern .

This guide gives you the complete overview of this microphone, its build quality and sound quality, its main advantages, its technical characteristics, as well as our opinion on the general quality of this microphone.

Neumann M149 and its 7-position high-pass filter

What makes the Neumann M149 different from other high-end models from this German brand is its low-cut filter .

Accessible from the rear of the microphone, this filter helps you optimize the results of your recordings . This allows you to attenuate low frequencies and let high frequencies pass through. The M149 offers you 7 levels of adjustments, including 20 Hz , 40 Hz , 80 Hz , 160 Hz and intermediate levels between each option.

Thanks to its high-pass filter, the M149 helps you low-frequency noise This could be, for example, noise from the wind or the air conditioning in your recording room.

This device also makes it easier for you to control audio when you place the microphone close to your electric guitar, for example.

Again, you can easily change the position of the filter since the switch is a sliding type.



Zoom on the sound quality of the Neumann M149

The Neumann M149 boasts exceptional sound quality . It notably offers a warm sound . Which is not surprising since it is a tube microphone. Tested on an acoustic guitar, it provides a rich , full sound with plenty of detail.

Another particularity of the sound of the Neumann M149: it reproduces the sound very precisely. On vocals, it delivers incredible precision whether for a man's voice or a woman's voice. For optimal results, however, be sure not to forget to choose the cardioid polar pattern when recording vocals .

The M149 also stands out for its very low background noise level , thanks in particular to its lamp and its circuit which benefits from modern technology. In fact, Neumann uses a transformerless output circuit. Furthermore, the built-in amplifier provides a high signal.

This microphone is hyper sensitive to the proximity effect . A completely normal characteristic since it is a static microphone. Remember not to bring your source too close to the microphone if you do not want to accentuate the bass.

You must therefore provide a professional recording studio or a home studio that is sufficiently acoustically treated to use this microphone. Indeed, it is also sensitive to surrounding noise.
