The Shure Beta 87A is a popular choice among live performers, especially for vocalists. Its design and technology provide several advantages that enhance live vocal performances. One of the key features of this microphone is its hypercardioid polar pattern.
Understanding the Hypercardioid Pattern
The hypercardioid pattern is a type of directional microphone pickup pattern. It captures sound primarily from the front while rejecting noise from the sides and rear. This pattern is more focused than a cardioid but less so than a supercardioid. It offers a balanced approach to isolating the desired sound source while maintaining some rejection of ambient noise.
Benefits of the Hypercardioid Pattern in Live Vocals
- Reduced Feedback: The hypercardioid pattern helps minimize feedback issues on stage by rejecting sound from the monitors and other sources behind the microphone.
- Enhanced Isolation: It isolates the vocalist’s voice from other stage sounds, ensuring clearer vocals in a noisy environment.
- Improved Sound Quality: With less ambient noise captured, the sound is cleaner and more focused, leading to better overall audio quality.
- Flexibility in Stage Setup: The pattern allows performers to move slightly without losing the quality of the sound pickup, providing some stage mobility.
Design Features Supporting Its Performance
The Beta 87A’s hypercardioid pattern is complemented by its supercardioid-like construction, which offers narrow acceptance angles. Its internal shock mount reduces handling noise, and the superlative frequency response ensures natural vocal reproduction. These features combined make it an excellent choice for live settings.
Practical Tips for Using the Beta 87A
- Maintain proper distance—typically 6-12 inches from the mouth—to optimize the hypercardioid pattern’s benefits.
- Avoid pointing the microphone directly at loud sound sources behind it to prevent unwanted noise pickup.
- Use appropriate windshields or pop filters to reduce plosive sounds and wind noise.
- Regularly check and adjust positioning to ensure consistent sound quality during performances.
Conclusion
The Shure Beta 87A’s hypercardioid pattern offers significant advantages for live vocal performances. Its ability to reject unwanted noise, reduce feedback, and deliver clear, natural sound makes it a valuable tool for performers seeking reliable and high-quality microphone performance on stage.
