Product Overview

The Neumann KK 183 nx is a precision pressure transducer that belongs to the KM A/D modular system. It features a true omnidirectional polar pattern that remains remarkably consistent across the entire frequency spectrum. The "nx" designation signifies the specialized Nextel Black matte finish—a non-reflective, scratch-resistant coating that is the industry standard for television, film sets, and high-end stage productions where equipment must remain visually unobtrusive under bright lights.

Product Description

Optimized for the Diffuse Sound Field:

Unlike microphones designed for close-up use, the KK 183 nx is diffuse-field equalized. In large concert halls or cathedrals, high frequencies are naturally absorbed by the air and room surfaces. The KK 183 nx features a deliberate +7 dB treble boost at 10 kHz in the free field (direct sound), which results in a perfectly flat and natural frequency response when the microphone is placed at a distance from the source. This ensures that distant recordings sound vibrant, detailed, and "airy."

Unlimited Low-Frequency Response:

As a true pressure transducer, the KK 183 nx has no proximity effect and offers a linear bass response down to 20 Hz. This allows it to capture the full weight and majesty of a pipe organ, the deep resonance of a grand piano, or the low-end fundamentals of an orchestral percussion section with absolute phase coherence and authority.

Modular & Future-Proof Design:

The KK 183 nx is a passive capsule that threads directly onto the KM A nx (Analog P48) or KM D nx (Digital AES 42) output stages. This modularity allows the capsule to be detached and used at a distance of up to 100 meters via specialized extension cables (like the LC 4), facilitating virtually invisible overhead placement in prestigious venues.

Reference-Grade Specs:

With an ultra-low self-noise of 13 dB-A and the ability to handle Sound Pressure Levels (SPL) up to 150 dB (when using the -10 dB pad on the KM A output stage), the KK 183 nx delivers an enormous dynamic range. It is built to Neumann's legendary standards in Germany, ensuring that every capsule sounds identical for perfect A-B stereo matching.

Applications

• Orchestral & Choral Recording: The industry standard for room ambience and main A-B arrays.

• Film & Television Production: Discreet, non-glare appearance for on-camera sets and boom poles.

• Organ & Piano Recording: Captures deep, authentic low-end that directional mics cannot replicate.

• Decca Tree Arrays: Ideal for the "outrigger" positions in a classic Decca Tree configuration.
