This overview examines the Radius Windshields Mini-ALTO, a blimp-style shock mount and windshield system, and compares it to several industry options, particularly those from Rycote, to evaluate performance in windy outdoor conditions.
Understanding Microphone Windshields
Windshields are essential tools in field recording, designed to reduce wind-induced distortion that can affect microphone audio. The main types include:
- Foam Covers: Typically included with microphones, these are effective in light wind (under ~2 mph) but may dampen higher frequencies.
- Foam + Fur Covers: Better for moderate breezes (~5–6 mph), though they can introduce some coloration.
- Zeppelin/Blimp-Style Covers: Most effective for stronger winds. Their design diffuses wind before it reaches the microphone, though they tend to be larger, heavier, and more complex to deploy.
Comparison of Zeppelin-Style Windshields
Several Rycote models offer benchmarks for comparison:
- Rycote Super Shield: Effective, but microphone access can be time-consuming due to screw-based assembly.
- Rycote Cyclone: Strong performance in high winds with convenient magnetic closure. Often eliminates the need for a fur cover.
- Rycote Nanoshield: Compact and lightweight with magnetic closure. Offers less wind protection due to its smaller size.
Evaluation of the Radius Mini-ALTO
The Radius Mini-ALTO shares design similarities with the Rycote Nanoshield but includes usability enhancements. Key features:
- Magnetic Basket Closure: Eases microphone access.
- Suspension Hoops: Adjustable for different mic weights.
- Accessory Clip: Useful for storage and workflow efficiency.
- Sound Transparency: Minimal audio coloration in tests.
Summary
Pros:
- Compact and lightweight
- Tool-free mic access
- Customizable shock suspension
- Practical accessories
- Competitive pricing
Cons:
- Requires manual hoop changes for different mics
- Limited wind resistance without fur cover (~4–5 mph)
The Mini-ALTO is a practical option for users seeking a user-friendly, moderately priced windshield system with effective wind protection and audio clarity.
