Product Overview

The Neumann KK 131 is a high-performance component of the KM A/D Series, Neumann’s premier modular small-diaphragm microphone system. As a pressure transducer, the KK 131 features a true omnidirectional polar pattern that remains remarkably consistent. This specific model is free-field equalized, meaning its sensitivity is tuned to be exceptionally flat for sound arriving directly from the front. It is the perfect tool for critical recording applications where the microphone is placed relatively close to the sound source.

Product Description

Reference-Grade Near-Field Accuracy:

The KK 131 is designed for engineers who demand total honesty in their recordings. Because it is free-field equalized, it does not have the high-frequency "boost" typically found in diffuse-field microphones. This results in a natural, uncolored sound when miking instruments at short distances, ensuring that the recording sounds exactly like the source without unwanted brightness or "hype."

Modular Versatility (Analog or Digital):

True to the KM A/D concept, the KK 131 capsule is passive and incredibly compact. It can be paired with the KM A analog output stage for a traditional high-end signal path (P48 phantom power) or the KM D digital output stage for direct AES 42 integration. This future-proof design allows you to adapt your gear to any studio or live environment.

Immaculate Phase Response:

As a pressure transducer with an omnidirectional characteristic, the KK 131 provides excellent low-frequency extension down to 20 Hz and maintains perfect phase coherence. This makes it a superior choice for A-B stereo recording or for use as a measurement-grade reference microphone in acoustic analysis.

Rugged & Discreet:

Finished in classic Satin Nickel, the KK 131 is small enough to remain nearly invisible on camera or on stage. Despite its size, it is capable of handling extreme Sound Pressure Levels (SPL) of up to 150 dB (when using the -10 dB pad on the KM A output stage), allowing it to be used even on very loud sound sources without distortion.

Key Features

• Free-Field Equalized: Perfectly flat frequency response for near-field and direct-sound applications.

• True Omnidirectional Pattern: Captures sound equally from all directions with minimal off-axis coloration.

• Modular Design: Compatible with both KM A (Analog) and KM D (Digital) output stages.

• Extended Low End: Accurate reproduction of frequencies down to 20 Hz.

• High SPL Tolerance: Handles up to 150 dB with pre-attenuation for distortion-free capture.

• German Engineering: Handcrafted for ultimate precision and long-term professional use.

   

   

Applications

• Solo Instrument Recording: Ideal for acoustic guitars, woodwinds, and strings at close range.

• A-B Stereo Miking: Use a matched pair for a natural, wide stereo image with deep bass.

• Speech & Vocal Capture: Provides a neutral, "human" sound for broadcast and podcasting.

• Acoustic Measurement: Suitable for room analysis and loudspeaker testing due to its flat response.
