27cm Nimbus Windshield for Audio-Technica BP28, Grey Fur

Audio-Technica BP28 Windshield with Pepper-Pot Technology

The 27cm Nimbus windshield represents a refined approach to wind protection for the Audio-Technica BP28 broadcast microphone. This slide-on windscreen incorporates proprietary pepper-pot end cap technology to achieve up to 25dB wind noise reduction while preserving high frequency audio clarity essential for professional broadcast applications.

Construction and Materials

The windshield features a dual-layer construction combining high-quality acoustic synthetic fur with a porous open cell foam core. The 25mm length dark grey synthetic fur provides the primary wind barrier, while the internal foam core maintains structural integrity and contributes to the overall acoustic performance.

The specially designed rubber end caps accommodate microphones with diameters between 19-22mm and 24-25mm, ensuring a secure fit around the BP28 capsule housing. This precise fit prevents wind ingress behind the microphone capsule, a critical factor in maintaining clean audio capture in challenging outdoor environments.

Pepper-Pot End Cap Innovation

The distinctive pepper-pot hole pattern integrated into the rear end cap represents a significant advancement in windscreen technology. These carefully positioned openings provide enhanced acoustic transparency compared to traditional solid end caps, reducing polar pattern distortion that can occur with conventional windshields.

This design maintains the microphone’s intended directional characteristics while still providing effective wind protection. The pepper-pot configuration allows controlled airflow that minimizes pressure build-up behind the capsule without compromising wind noise attenuation.

Professional Broadcasting Applications

The Audio-Technica BP28 is widely deployed in broadcast environments ranging from field reporting to sports commentary. This windshield extends the microphone’s operational envelope in outdoor conditions where wind noise would otherwise compromise audio quality.

News gathering operations frequently encounter unpredictable weather conditions where wind noise can render footage unusable. The 27cm length provides comprehensive coverage of the BP28’s shotgun capsule while maintaining the microphone’s reach and directional pickup pattern.

Sports broadcasting presents particular challenges with exposed stadium environments and crowd-generated air movement. The windshield’s 25dB wind noise reduction ensures consistent audio quality throughout extended broadcast periods.

Installation and Workflow Integration

The slide-on design facilitates rapid deployment in fast-paced broadcast scenarios. The windshield slides over the microphone barrel and seats against the rear mounting hardware, creating an effective seal without requiring tools or additional fasteners.

Camera-mounted configurations benefit from the streamlined profile that doesn’t interfere with lens operation or camera movement. The grey synthetic fur provides visual discretion while the windshield’s length accommodates various mounting positions along the microphone body.

Audio engineers can quickly assess wind conditions and deploy the windshield as needed, with installation taking seconds rather than requiring extensive setup modifications. The secure fit ensures the windshield remains properly positioned throughout demanding recording sessions.

Acoustic Performance Characteristics

The windshield maintains the BP28’s frequency response characteristics while providing substantial wind noise attenuation. The acoustic synthetic fur material is specifically selected for minimal impact on high frequency reproduction, crucial for maintaining broadcast audio standards.

The porous foam core contributes to the overall acoustic transparency while providing structural support for the fur layer. This combination prevents the windshield from becoming a secondary acoustic filter that could color the microphone’s natural response.

Field testing demonstrates consistent performance across the BP28’s operating frequency range, with particular attention paid to preserving the clarity essential for speech reproduction in broadcast applications. The Audio-Technica BP28 maintains its characterized sound signature when used with this windshield system.

Care and Maintenance

Regular inspection of the synthetic fur condition ensures continued performance. Environmental debris can accumulate in the fur over time, potentially affecting both acoustic and visual presentation.

Gentle brushing with a soft-bristled brush removes surface debris and maintains the fur’s appearance. The windshield should be stored in protective housing when not in use to prevent damage to the delicate fur fibers.

Storage in controlled temperature environments prevents degradation of the rubber end caps and foam core materials. Proper care extends the windshield’s operational life while maintaining consistent acoustic performance throughout its service period.
