Product Overview

The KM 184 Stereo Set is the essential choice for engineers who demand total acoustic symmetry. While the "Series 180" offers various patterns, the KM 184's cardioid response has made it the industry's most versatile "pencil mic." Each set is meticulously matched at the Neumann factory in Germany to ensure identical frequency response and sensitivity between the two units. This guarantees the phase-coherent accuracy required for professional stereo arrays such as XY, ORTF, and spaced pairs.
 

Product Description

The "Fresher" Neumann Sound:

The KM 184 is the modern successor to the legendary KM 84. While it retains the same capsule design, it features a slightly different tonal balance: a gentle +3 dB treble rise at 9 kHz. This characteristic adds a "fresh" and "lively" quality to recordings, allowing acoustic guitars, pianos, and percussion to cut through a mix with natural brilliance without requiring heavy equalization.

Unrivaled Cardioid Isolation:

As a pressure gradient transducer, the KM 184 features a highly consistent cardioid polar pattern that is frequency-independent. It provides excellent rejection of sound from the rear ($180^{\circ}$) even at low frequencies. This makes it a "problem-solver" on loud stages and in tight studio spaces, effectively isolating the source instrument from bleed and background noise while maintaining a perfectly uncolored off-axis response.

Elite Transformerless Engineering:

The internal circuitry utilizes the FET 100 transformerless design from the high-end KM 100 system. This results in a massive dynamic range of 125 dB and an ultra-low self-noise floor of only 13 dB-A. It can handle extreme Sound Pressure Levels (SPL) up to 138 dB without distortion, making it equally capable of capturing a delicate solo violin or high-intensity drum overheads.

Iconic Design & Reliable Performance:

Measuring just 107 mm in length with a stunning Satin Nickel finish, these microphones offer a timeless aesthetic that looks as good as it sounds. The low-impedance output stage is designed to drive long cable runs—up to 300 meters (1000 feet)—without any signal loss or interference, ensuring studio-grade audio in any environment.
