Product Overview

The WNS 120 (008427) is designed to meet the unique requirements of the KM 120’s figure-8 polar pattern. Because bidirectional microphones are inherently more sensitive to air movement, the WNS 120 is an essential tool for both indoor close-miking and moderate outdoor use. It features a larger diameter (48 mm) than the standard KM 184 windscreens to properly encapsulate the side-address nature of the AK 20 capsule. Tested in turbulent air streams of 20 km/h, it provides reliable attenuation without inducing unwanted resonances or altering the microphone’s signature directional characteristics.

Product Description

Acoustic Transparency for Figure-8 Accuracy:

The most critical feature of the WNS 120 is its ability to protect the capsule without muffling the sound. Open-cell polyurethane foam is chosen for its porous structure, which allows sound waves to pass through while diffusing turbulent air. This results in an incredibly low impact on the frequency response, with only a 2 dB attenuation at 15 kHz. For engineers using the KM 120 in delicate MS (Mid-Side) or Blumlein stereo arrays, this transparency ensures that the stereo image and high-frequency "air" are perfectly preserved.

Combatting "Boom" and Movement Noise:

In broadcast and film production, fast movements of a microphone boom can create low-frequency thumps. The WNS 120 is designed to neutralize these subsonic disturbances. Whether it’s the rustling of manuscript pages in a voice-over booth or the air displacement from a moving boom arm, this windscreen acts as a vital buffer, keeping your audio signal free from mechanical noise interference.

Physical Protection for Delicate Capsules:

Beyond wind protection, the WNS 120 serves as a protective layer for your high-end Neumann investment. It shields the dual-diaphragm AK 20 capsule from dust, moisture, and saliva during vocal recording. Its snug, slip-on design ensures a secure fit that matches the professional aesthetic of the Neumann KM Series.

Optimized Compatibility:

While it may fit other 22mm-body microphones, the WNS 120 is the factory-specified accessory for:

• Neumann KM 120 (Small Diaphragm Figure-8 Microphone)

• Neumann AK 20 (Active Figure-8 Capsule)

• KM A / KM D systems utilizing the KK 120 or AK 20 capsules.

Key Features

• Targeted Figure-8 Design: Specifically shaped to optimize the performance of the KM 120.

• Open-Cell Polyurethane: High-grade foam for long-lasting durability and transparency.

• Significant Noise Reduction: Provides 15 dB of wind noise attenuation.

• Minimal Tonal Coloration: Only a subtle 2 dB attenuation at the 15 kHz frequency mark.

• Pattern Neutrality: Does not interfere with the microphone's figure-8 pickup pattern.

• Tested for Turbulence: Performance verified in air streams traveling at 20 km/h.

• Sleek Matte Black: Professional appearance for studio, stage, and camera work.

Applications

• Mid-Side (MS) Recording: Essential for the "Side" (KM 120) microphone in stereo arrays.

• Blumlein Stereo: Protects both microphones in a coincident figure-8 configuration.

• Close-Miking Strings: Ideal for cellos and upright basses where a figure-8 pattern is used for isolation.

• Broadcasting & Interviews: Minimizes plosives and breath noise in bidirectional interview setups.

• Location Recording: Essential for outdoor work to prevent light wind gusts from ruining takes.
