Using the Electro-Voice RE20 microphone can significantly enhance your audio quality, but managing noise and feedback is essential for professional sound. This guide provides practical tips to reduce unwanted noise and feedback during your recordings or live performances.

Understanding Noise and Feedback

Before implementing solutions, it's important to understand what causes noise and feedback. Noise often originates from electronic interference, poor cable connections, or environmental factors. Feedback occurs when sound from speakers re-enters the microphone, creating a loop that amplifies loud, high-pitched squeals.

Proper Microphone Placement

Position your RE20 correctly to minimize feedback and noise. Keep the microphone at an appropriate distance from speakers—typically 6 to 12 inches—and angle it away from monitors or speakers to prevent sound from re-entering the mic.

Avoid Direct Speaker Line-of-Sight

Ensure the microphone is not directly facing loudspeakers. Use monitor placement and directional positioning to reduce the likelihood of feedback loops.

Use Proper Gain Settings

Adjust the gain on your mixing console or audio interface carefully. Too high gain amplifies background noise and increases the chance of feedback. Start with a low gain and gradually increase it until you achieve clear sound without distortion.

Implement Acoustic Treatments

Reduce environmental noise by adding acoustic panels, foam, or curtains to absorb sound reflections. This minimizes echo and background noise, resulting in cleaner audio recordings or live sound.

Utilize Feedback Suppressors and Equalizers

Employ feedback suppressors or equalizers to identify and cut problematic frequencies. Narrowband notch filters can target specific feedback frequencies, effectively reducing squeals without affecting overall sound quality.

Connect Quality Cables and Equipment

Use high-quality, shielded cables to prevent electronic interference. Ensure all connections are secure and free of damage, as faulty cables can introduce noise and signal loss.

Regular Equipment Maintenance

Check your microphone, cables, and audio equipment regularly for signs of wear or damage. Clean connectors and replace faulty components promptly to maintain optimal performance.

Summary of Best Practices

  • Position the microphone properly, away from speakers and reflective surfaces.
  • Adjust gain settings carefully to avoid distortion and noise.
  • Use acoustic treatments to minimize environmental reflections.
  • Employ feedback suppressors and equalizers to target problematic frequencies.
  • Use quality cables and maintain your equipment regularly.

By following these tips, you can significantly reduce noise and feedback when using your Electro-Voice RE20, ensuring clear and professional audio quality in any setting.
