Neumann KM 184 A nx Cardioid Small-Diaphragm Condenser Microphone – Nextel Black

Neumann KM 184 A nx Modular Cardioid Small-Diaphragm Condenser Microphone

The Neumann KM 184 A nx is a premium modular small-diaphragm condenser microphone engineered for professional recording applications that demand exceptional accuracy, transparency, and flexibility. Combining the renowned KK 184 cardioid capsule with the KM A analog output stage, this microphone delivers the classic Neumann small-diaphragm sound with low self-noise, extended dynamic range, and outstanding off-axis consistency. Finished in Neumann's durable Nextel® black coating, the KM 184 A nx is ideally suited for studio recording, broadcast, classical music, live production, and location recording.

As part of the Neumann KM A modular microphone system, the KM 184 A nx offers the flexibility to interchange compatible capsule heads while maintaining the proven performance of the analog output stage. Its compact design, transformerless electronics, and excellent electromagnetic immunity make it a dependable solution for professional engineers working in demanding recording environments.

Natural Cardioid Pickup with Outstanding Accuracy

The KK 184 capsule is a pressure-gradient transducer featuring a cardioid polar pattern with extremely uniform frequency response across a wide pickup angle. This design minimizes off-axis coloration, allowing instruments and vocals to retain their natural tonal balance even when sound arrives from different directions. The result is precise imaging, excellent isolation, and highly detailed recordings suitable for critical stereo and mono applications.

Professional Modular KM A System

The KM 184 A nx belongs to Neumann's modular KM A/D microphone system, allowing compatible capsule heads to be paired with either the analog KM A output stage or the digital KM D output stage. The modular architecture enables engineers to adapt the microphone to different recording scenarios using extension tubes, remote cables, swivel joints, and other professional accessories without changing the core microphone system.
