Shure SM-58S Cardioid Dynamic Mic - On-Off Switch

The Shure SM58S is simply the Shure SM58 dynamic vocal microphone, but with the added feature of an integrated on/off switch. The "S" suffix in the model name denotes the presence of this switch.

All the legendary qualities of the standard SM58-LC remain: its iconic sound, unparalleled durability, and excellent feedback rejection. The switch just adds an extra layer of user control.

Here's a detailed look at its key features, with emphasis on the switch:

Key Differentiating Feature: The Switch

• Integrated On/Off Switch: This is the defining characteristic of the SM58S.

  • Convenient Control: Allows the performer or speaker to quickly and easily mute or unmute the microphone directly on the body. This is particularly useful in situations where individual control is preferred or a mixing console isn't readily accessible for quick mutes.

  • Silent Operation: Shure's switches are designed to operate silently, minimizing any audible "thump" or "pop" through the sound system when engaged or disengaged.

  • Lockable (on some models/iterations): While not explicitly stated for all SM58S versions, some professional switches can be locked in the ON or OFF position to prevent accidental activation or deactivation during a performance.

Core Features (Shared with the standard SM58-LC):

• Dynamic Microphone (Moving Coil): Inherently rugged, capable of handling extremely high sound pressure levels (SPLs) without distortion, making it perfect for powerful vocalists and loud stage environments.

• Cardioid Polar Pattern: This is the most common and versatile pickup pattern for live vocals. It focuses sound capture directly in front of the microphone, effectively rejecting sounds from the sides and rear. This provides:

  • Excellent Feedback Rejection: Minimizes the likelihood of feedback from stage monitors and main PA systems.

  • Strong Isolation: Helps isolate the vocalist's voice from other instruments on a busy stage, contributing to a cleaner mix.

• Tailored Frequency Response: The SM58 has a distinctive, contoured frequency response (typically 50 Hz to 15,000 Hz) specifically shaped for vocals. It features a gentle presence boost in the upper midrange (around 2-5 kHz) to help vocals cut through a mix and ensure intelligibility, along with a bass roll-off to control proximity effect and reduce unwanted low-frequency rumble.

• Highly Effective, Built-in Spherical Filter: The iconic spherical mesh grille acts as a very effective integrated pop filter, minimizing "pop" noises from plosive breath sounds ("p" and "b" sounds) and reducing wind noise.

• Pneumatic Shock Mount System: The internal microphone cartridge is isolated by Shure's advanced pneumatic shock mount. This effectively minimizes the transmission of mechanical noise and vibrations (like handling noise from holding the mic or stand-transmitted rumble), ensuring a cleaner vocal signal.

• Durability (Legendary "Built Like a Tank"): The SM58 is famously rugged. Its all-metal construction and robust steel mesh grille are designed to withstand severe abuse on stage and in the studio, ensuring years of reliable performance. It's known for surviving countless drops, impacts, and general wear and tear.

Applications:

• Lead Vocals & Background Vocals: Remains a top choice for singers across all genres, offering reliable sound and the added control of the switch.

• Public Address (PA) and Speeches: The switch is particularly useful for presenters, lecturers, and anyone who needs to quickly mute their mic.

• Karaoke: Very popular for home and professional karaoke setups where direct user control is often desired.

• Any Situation Requiring On-Mic Muting: Ideal for situations where a sound engineer might not be able to provide quick mutes, or for personal control.

Included Accessories:

• Microphone Clip

• Protective Pouch

In summary, the Shure SM58S delivers the exact same legendary sound and bulletproof reliability of the standard SM58, with the added practical benefit of a silent, integrated on/off switch, making it an even more versatile tool for a wider range of vocal and speech applications.
