18cm Nimbus Windshield (19/22), Black Fur

Professional Wind Protection for Shotgun Microphones

The 18cm Nimbus windshield represents a specialized approach to wind noise reduction for professional shotgun microphones within the 19-22mm diameter range. This slide-on windscreen addresses the fundamental challenge of maintaining audio quality while providing effective protection against wind interference in field recording environments.

The windshield incorporates a dual-layer construction system featuring a porous open-cell foam internal core surrounded by high-quality synthetic black fur. This combination provides up to 25dB of wind noise reduction while preserving high-frequency audio clarity essential for broadcast and production applications.

Innovative End Cap Design

The distinguishing feature of this windshield lies in its specialized rubber end caps, engineered to accommodate microphones between 19mm and 22mm in diameter. These caps create a secure seal around the microphone body, preventing wind from entering behind the capsule where traditional windscreens often fail to provide adequate protection.

The end caps incorporate a unique “pepper pot” perforation pattern, featuring strategically positioned small openings that maintain acoustic transparency while blocking wind ingress. This design element reduces polar pattern distortion commonly associated with solid end cap windscreens, allowing the microphone to maintain its intended directional characteristics during use.

Microphone Compatibility and Sizing

This 18cm windshield accommodates shotgun microphones with overall lengths of 18cm or less from the end of the microphone body. Compatible models include the Rode NTG-3, Sanken CS-3e, Sennheiser ME66 K6, MKH416, and MKH418-S, along with Sony ECM-678 and ECM-680S models. The 19-22mm diameter range covers a substantial portion of professional shotgun microphones used in broadcast and field recording applications.

The windshield slides directly onto the microphone without requiring additional mounting hardware or modification to existing suspension systems. This compatibility extends to most standard shock mounts and boom pole attachments, allowing for seamless integration into established recording workflows.

Field Recording Applications

In broadcast journalism environments, this windshield provides reliable wind protection for outdoor interviews and location recording where moderate wind conditions might otherwise compromise audio quality. The black synthetic fur finish offers visual discretion for on-camera applications while maintaining professional appearance standards.

Documentary and film production crews benefit from the windshield’s ability to maintain audio transparency during directional recording scenarios. The pepper pot design ensures that the microphone’s polar pattern remains consistent, preserving the acoustic characteristics that make shotgun microphones effective for selective audio capture in challenging environments.

Acoustic Performance Characteristics

The synthetic fur outer layer creates the primary barrier against wind turbulence, with individual fibers disrupting airflow patterns before they reach the microphone capsule. The internal foam core provides secondary filtration while maintaining acoustic porosity necessary for natural frequency response.

High-frequency audio clarity remains intact through careful material selection and construction techniques. The combination of synthetic fur density and foam cell structure allows acoustic energy to pass through while attenuating wind-generated noise across the audible spectrum.

Professional Maintenance and Storage

The synthetic fur construction resists moisture absorption and maintains its protective characteristics through repeated use in varying weather conditions. Regular inspection of the end cap seal ensures continued effectiveness, particularly in environments where microphones are frequently mounted and removed.

Storage recommendations include maintaining the windshield in its natural shape to preserve the effectiveness of both the fur layer and internal foam structure. The black coloration provides practical advantages in situations where visual discretion is important while offering good dirt resistance for extended field use.

Professional users should consider having multiple windshields available for extended recording sessions where changing weather conditions might require fresh protection or when working with multiple microphone configurations simultaneously.
