Description of the Neumann KM184

The Neumann KM184 is a condenser microphone with a cardioid capsule. It is a compact and versatile microphone , usable on stage, in the studio or for radio recordings. It can also be used for nearby recording of various instruments such as the piano, guitars (acoustic guitar or bass guitar), etc.

The KM184 model is the best classic studio microphone of very high quality. The sound produced is faithful to the original: an authentic sound . Very easy to use, the Neumann KM184 will be your ally in immortalizing your ingenuity.

KM184 is available in stereo pair form and has a unidirectional cardioid polar pattern. Also, it is the successor of KM84. On the other hand, the two microphones have a slight difference in frequency response.

And this difference brought a notable result in terms of the sound produced. Equipped with the same capsule as the KM 84, the KM184 increases slightly around a frequency of 9 kHz. This then gives a much fresher and livelier tone compared to that of its predecessor.



In addition, it finds its place on stage to amplify a musical instrument. But it is also an essential recording equipment in the studio. When faced with a microphone like the Neumann KM184 or the Neumann TLM 193 microphone , you can only marvel at its efficiency and versatility.

In any case, it's an all-purpose microphone, where we apply all the right rules and placement adjustments. Additionally, it generates rich sound in close proximity.

Also, even if you are a beginner, or a professional musician, it will win you over. Moreover, it will never produce bad sound due to its perfectly controlled frequency response and off-axis phase. Its cardioid curve is also complete and well constructed.

Design of the Neumann KM184

The Neumann KM184, like the Neumann U87, a typical microphone of the German brand, has a diameter of 22 millimeters and a weight of 80 grams in total. In addition, its 10-centimeter stick shape ensures great ergonomics .

Its finish also remains impeccable, particularly in terms of the metal structure. The tripod mounts, on the other hand, lock in place very easily and look very professional. In addition, they provide a secure hold when using microphones.



Furthermore, the KM184 microphone is available in two colors: nickel and matte black. It is also a very durable and compact microphone that incorporates a transformerless output circuit. It is offered as a Stereo Set, a set of two microphones, or as an Octo-Set, consisting of 8 microphones in total.

For each set, you have a very elegant wooden box, SG 21/17 mt clips and WNS 100 foam windshields.

Cardioid polar pattern

Thanks to its optimized design, the KM184 meets the demands of amateurs or professionals looking for a high-performance microphone on a fairly limited budget. Indeed, the Neumann KM184 microphone is equipped with a cardioid polar pattern.

Very versatile, it is designed for vocals, instrument recording and more. The KM184 captures every detail and its cardioid polar pattern lets it focus on what's important. It is the guarantor of your performance, because it will not pick up any background noise or feedback.

For optimal sound recording, be sure to position it directly in line with the sound source.

Acoustic characteristics of the Neumann KM184

The main characteristics of the KM184 remain faithful to those of its predecessor, the KM84. Equipped with recent electronic components and a very small capsule, the KM184 offers an exceptional sound experience .

In fact, the system used contributes to reducing the level of inherent noise. This, while allowing very high insensitivity to electromagnetic interference. The microphone has a pre-attenuation selector. Therefore, it can withstand sound pressure levels of up to 152 dB/Spl.



That said, the KM184 pressure gradient transducers have a very linear frequency curve for on-axis (0) and lateral incidence. Therefore, when using it, you will not detect any coloring.

From 200 Hz, the curve drops slightly downwards. In the treble, the picture is reversed. Then, from 5 Hz, the curve rises slightly and peaks at 8 Hz before falling back to 0. In fact, this results from a slight modification of the openings of the rear microphone capsule.

The sound pressure level of the KM184 is 138 dB, a very good value and the distortion factor is only 0.5%. In all respects, Neumann remains a very good reference for competition . To capture different types of sound, the KM184 was able to prove its full performance.

Therefore, it is also a microphone suitable for voice-overs, for broadcasting, for podcasts and for singing with the application of a windshield. It is a professional microphone suitable for use by the general public, including beginners. In addition, it offers unbeatable value for money and extremely rare sound quality .



When recording in a studio, the microphone helps capture sound with authentic audio quality. Moreover, its spectral density gives you real coloring and correction capabilities. But, for certain models and lower ranges, this manipulation will be much more hazardous.

Thanks to this spectral density, the KM184 offers very rich and authentic sound. For live use, the microphone exceeds all expectations. In this case, it provides excellent sound without having to fiddle with the EQ in all directions.

Ideal for studio recordings.

Electrical characteristics of the Neumann KM184

The KM184 uses a transformerless output circuit. This gives it excellent technical characteristics. Compared to its predecessor, the dynamic range of the KM184 is 24 dB greater. In fact, it owes this quality to the reduction of its own noise level and the increase in its sound pressure level.



Furthermore, the output of the KM184 is symmetrical. After extensive testing, we can say that the microphone works perfectly even if the recorder input is unbalanced. As a small-diaphragm condenser microphone, the Neumann 184 naturally requires 48 volts (+/- 4 V) phantom power to operate.

Two identical resistors divide the power terminal. Then, half of the direct current passes through each audio conductor, while the other half goes back to the source via the shield cable.

This system is fully compatible, as there is no difference between the two audio drivers. This system is ideal for powering all types of microphones.
