Shure SM57-LC Dynamic Instrument Microphone

Product Overview

The Shure SM57-LC is a cardioid dynamic instrument microphone engineered for demanding commercial AV and professional audio applications. Used by the United States Secret Service at the presidential podium for decades, the SM57 delivers consistent, reliable performance in sound reinforcement, broadcast, and recording environments. Its contoured frequency response is tailored for accurate reproduction of amplified and acoustic instruments without coloration. The SM57-LC ships without a cable, making it straightforward to integrate into existing AV signal chains.

Product Description

The Shure SM57-LC is the professional standard for instrument miking in commercial AV installations, broadcast studios, and live event spaces. Its cardioid polar pattern focuses pickup on the source while rejecting off-axis noise — essential in multi-microphone setups common in conference rooms, auditoriums, and broadcast facilities. The pneumatic shock-mount system reduces handling and stand-borne vibration noise, contributing to cleaner signal capture during commercial sound reinforcement. A polycarbonate grille with stainless steel screen protects the element and stands up to the rigors of daily use in any installation environment. The die-cast steel body with dark gray enamel finish is built for commercial-grade durability. For a complementary vocal dynamic microphone for sound reinforcement, see the Shure SM58S available at Creation Networks.

Key Features

• Cardioid Polar Pattern — Focuses pickup directly in front of the microphone, rejecting ambient noise and bleed from adjacent sources in multi-microphone AV setups.
• Contoured Frequency Response (40–15,000 Hz) — Shaped for clean, accurate reproduction of both amplified and acoustic instruments without excessive coloration.
• Pneumatic Shock-Mount System — Mechanically isolates the capsule from handling and stand-borne vibration, reducing low-frequency noise in live and installed AV environments.
• Commercial-Grade Die-Cast Steel Body — Dark gray enamel finish construction withstands daily use in installed and portable sound reinforcement systems.
• Low Output Impedance (310 Ohms) — Compatible with professional balanced XLR signal chains and long cable runs standard in commercial AV installations.
• LC (Less Cable) Configuration — Ships without cable, allowing integrators to specify and use their preferred cable type and length in any system configuration.
