The Electro-Voice RE320 is a versatile dynamic microphone widely used in broadcasting, recording, and live sound applications. Its ability to capture clear and detailed audio makes it a favorite among professionals and enthusiasts alike. Understanding the microphone’s polar patterns is essential to maximize its performance in various settings.
Understanding Microphone Polar Patterns
Microphone polar patterns describe how a microphone picks up sound from different directions. They influence the quality of audio capture, background noise rejection, and feedback control. Different patterns suit different recording environments and purposes.
The Cardioid Pattern
The cardioid pattern is one of the most common and versatile polar patterns used with the RE320. It is named after its heart-shaped pickup pattern, which primarily captures sound from the front while rejecting noise from the sides and rear. This makes it ideal for many applications, including vocals, podcasts, and live performances.
Features of the Cardioid Pattern
- Focuses on sound directly in front of the microphone
- Reduces pickup of ambient noise and room reflections
- Provides some rejection of sounds from the sides
- Helps prevent feedback in live sound environments
The cardioid pattern’s directional focus makes it excellent for isolating the desired sound source, especially in noisy environments or when multiple sound sources are present.
Other Microphone Patterns and Their Relevance
While cardioid is the most common for the RE320, understanding other patterns can be beneficial for specialized applications.
Supercardioid and Hypercardioid
These patterns are more directional than cardioid, offering greater rejection of side noise but with a slightly increased pickup from the rear. They are useful in stage environments where feedback control is critical.
Omnidirectional
This pattern captures sound equally from all directions. It is rarely used with the RE320 but can be suitable for capturing ambient room sound or group recordings.
Choosing the Right Pattern for Your Needs
The decision to use cardioid or another pattern depends on your recording environment and goals. For most vocal and broadcast applications, cardioid offers an excellent balance of focus and rejection. For stage performances requiring maximum feedback control, supercardioid or hypercardioid may be preferred.
Conclusion
The Electro-Voice RE320’s compatibility with various polar patterns, especially cardioid, makes it a flexible choice for many audio tasks. Understanding the strengths of the cardioid pattern helps users optimize their setup for clear, focused sound and minimal background noise.
