The Ultimate Guide to the Legendary SM58LC Vocal Microphone from Shure

Introduction

The Shure SM58LC is a cardioid dynamic microphone that has become an iconic choice for vocalists around the world. Renowned for its exceptional sound quality, durability, and versatility, the SM58LC has been a mainstay in live performances, recording studios, and broadcast applications for decades. In this comprehensive guide, we will dive into the intricacies of this legendary microphone, exploring its features, benefits, and best practices for optimal use.

The Legacy of the SM58

The SM58's journey began in 1966 when Shure engineers set out to create a microphone that could withstand the rigors of live performances while delivering pristine audio. The result was the original SM58, which quickly gained popularity among musicians and sound engineers alike. Over the years, the SM58 has undergone several refinements, culminating in the current SM58LC model.

Features and Benefits of the SM58LC

Dynamic Cartridge: The SM58LC employs a unidirectional dynamic cartridge, which is less sensitive to feedback than condenser microphones. This makes it ideal for high-volume environments, such as live concerts and loud stage settings.

Cardioid Polar Pattern: The cardioid polar pattern focuses sound pickup in a cone-shaped area in front of the microphone, minimizing off-axis noise and feedback. This allows for greater vocal clarity and isolation.

Frequency Response: The SM58LC has a tailored frequency response that complements the human voice. It features a slight boost in the mid-range frequencies, enhancing the presence and intelligibility of vocals.

Built-In Pop Filter: The microphone's built-in pop filter effectively reduces plosives and wind noise, ensuring a clean and consistent sound.

Rugged Construction: The SM58LC is renowned for its exceptional durability. Its metal construction and shock-mounted cartridge can withstand rough handling and accidental drops.

Interchangeable Capsule: The SM58LC's capsule is interchangeable with other Shure SM58 variants, offering versatility for different sound situations.

Best Practices for Using the SM58LC

Microphone Placement: Position the microphone approximately 2-4 inches from the vocalist's mouth, slightly off-axis to minimize plosives and sibilance.

Proper Grip: Hold the microphone firmly but gently, avoiding over-tightening. Use a mic stand or grip to ensure stable positioning.

EQ Settings: As a starting point, consider using a slight high-pass filter to reduce low-end rumble and a mid-range boost for added presence.

Stories and Lessons

Story 1: The Power of Preparation

Lesson: Always test your equipment before a performance. During a live concert, a vocalist's SM58LC suddenly stopped working. Upon inspection, the sound engineer discovered a loose cable connection. By quickly troubleshooting and resolving the issue, the performance was able to continue without interruption.

Story 2: The Importance of Microphone Technique

Lesson: Proper microphone technique can greatly improve sound quality. When a vocalist held the SM58LC too close to their mouth, their voice became muffled and unclear. By adjusting the microphone's placement and experimenting with different distances, the sound engineer achieved a more balanced and resonant vocal sound.

Story 3: The Benefits of Interchangeability

Lesson: The SM58LC's interchangeable capsule allows for greater flexibility in different sound environments. During a studio recording session, the sound engineer swapped out the SM58LC's standard capsule for an extended high-frequency capsule. This enhanced the vocalist's sibilance and added a touch of sparkle to their performance.

Common Mistakes to Avoid

• Over-amplifying the Microphone: Gaining the microphone too high can lead to feedback and distortion. Adjust the gain level until the vocalist's voice is clear and present without any unwanted background noise.
• Using the Microphone Off-Axis: Holding the microphone off-axis from the sound source can result in decreased volume and poor sound quality. Ensure the microphone is pointed directly at the vocalist's mouth.
• Ignoring the Pop Filter: Neglecting to use the built-in pop filter can cause distracting plosives and wind noise. Always use the pop filter for a clean and professional sound.
• Over-compressing the Microphone Signal: While compression can enhance vocal clarity, over-compressing the SM58LC can make the sound dull and lifeless. Use compression sparingly and focus on preserving the natural dynamics of the voice.
