Neumann KM 185 A nx Hypercardioid Small-Diaphragm Condenser Microphone – Nextel Black

Neumann KM 185 A nx Modular Hypercardioid Small-Diaphragm Condenser Microphone

The Neumann KM 185 A nx is a professional modular small-diaphragm condenser microphone designed for highly directional recording applications where superior source isolation and outstanding sonic accuracy are essential. Combining the Neumann KK 185 hypercardioid capsule with the KM A analog output stage, this microphone delivers exceptional detail, extended dynamic range, low self-noise, and excellent rejection of off-axis sound. Finished in Neumann's durable Nextel^® black coating, the KM 185 A nx is ideally suited for professional studio recording, broadcast, live sound reinforcement, film production, and location recording.

As part of the Neumann KM A modular microphone system, the KM 185 A nx provides outstanding flexibility by allowing compatible capsule heads to be paired with the analog output stage. The modular design supports a wide range of accessories, extension tubes, and remote mounting solutions, making it an excellent choice for engineers who require adaptable microphone placement without compromising audio quality.

Highly Directional Hypercardioid Pickup

The KK 185 capsule utilizes a pressure-gradient transducer with a hypercardioid polar pattern, providing excellent rejection of unwanted sound from the sides and rear. Side and rear sound is attenuated by approximately 10 dB, with minimum sensitivity occurring at approximately 120°, allowing the microphone to capture the intended sound source with exceptional focus and clarity. This makes it particularly effective in acoustically challenging environments or when recording multiple performers simultaneously.

Professional Modular KM A System

The KM A/D modular system allows the capsule and output stage to be separated using optional extension cables of up to 100 meters, providing remarkable installation flexibility for orchestral recording, broadcast production, theatre, houses of worship, and film applications. The transformerless KM A output stage operates using standard 48 V phantom power and features switchable 10 dB pre-attenuation, enabling the microphone to handle extremely high sound pressure levels with minimal distortion.
