The Shure Beta 87A is a popular condenser microphone known for its clear sound quality and durability. Its design makes it a common choice among performers and sound engineers. But when it comes to outdoor performances, questions often arise about its suitability. This article explores whether the Beta 87A is a good option for outdoor use and what factors should be considered.
Understanding the Shure Beta 87A
The Beta 87A is a supercardioid condenser microphone designed primarily for vocal applications. It offers high gain before feedback, excellent rejection of ambient noise, and a smooth, natural sound. Its robust construction makes it suitable for various stage environments, but outdoor settings pose unique challenges.
Advantages of the Beta 87A for Outdoor Use
- Sound Quality: The microphone provides clear, detailed vocals, which can be advantageous in outdoor environments where ambient noise varies.
- Durability: Its sturdy build helps it withstand some environmental factors like light rain or wind, although it is not fully weatherproof.
- Feedback Rejection: The supercardioid pattern helps reduce feedback issues, which are common in outdoor setups with multiple sound sources.
Limitations and Considerations
- Vulnerability to Weather: As a condenser microphone, the Beta 87A is sensitive and not designed for exposure to moisture or extreme weather conditions.
- Power Requirements: It requires phantom power, which must be supplied by the sound system, potentially complicating outdoor setups.
- Wind Noise: Without proper wind protection, the microphone can pick up wind noise, affecting sound quality.
- Handling Noise: Its sensitivity also means that handling noise can be more noticeable, so careful handling or use of a shock mount is recommended.
Tips for Using the Beta 87A Outdoors
- Use Windshields: Employ a foam or furry windscreen to reduce wind noise and protect the microphone from moisture.
- Secure Setup: Mount the microphone securely to prevent handling noise and accidental drops.
- Weather Considerations: Avoid using the microphone in heavy rain or extreme humidity; consider weatherproof alternatives if needed.
- Power Supply: Ensure your sound system provides phantom power and is suitable for outdoor environments.
Alternatives for Outdoor Performances
- Dynamic Microphones: Models like the Shure SM58 are more resistant to weather and handling noise, making them suitable for outdoor use.
- Wireless Microphones: Wireless systems with rugged, weather-resistant microphones offer mobility and protection from environmental factors.
- Specialized Outdoor Mics: Consider microphones specifically designed for outdoor environments, such as shotgun mics or waterproof models.
Conclusion
The Shure Beta 87A can be used outdoors under certain conditions, especially in controlled environments like covered stages or with protective accessories. However, its sensitivity and lack of weatherproofing mean it is not the ideal choice for harsh outdoor conditions. For outdoor performances, performers and sound engineers should weigh the advantages of sound quality against environmental challenges and consider more rugged alternatives if necessary.
