Shure SM57-LC Dynamic Instrument Microphone

Shure SM57-LC Dynamic Instrument Microphone

The Shure SM57-LC is the cable-free version of the most widely used instrument microphone in professional audio. The SM57 design has been the default choice for snare drums, tom-toms, guitar amplifier cabinets and brass for decades, on studio sessions and live stages alike. The LC suffix simply means the package ships without a microphone cable, which suits buyers who already own quality XLR leads or prefer to choose their own length.

Its reputation rests on three things: a tailored frequency response that adds presence and punch to instruments, a cardioid pattern that isolates the source from neighbouring sound, and construction that survives the realities of touring, rehearsal rooms and backline drawers. A pneumatic shock-mount system inside the microphone reduces handling and mechanical noise, and the grille is built to take stick hits and drops.

Key features

• Dynamic microphone tailored for instruments and amplifiers
• Cardioid polar pattern for source isolation and feedback control
• Frequency response from 40 Hz to 15 kHz with presence emphasis
• Pneumatic shock mount reduces mechanical and handling noise
• Handles very high sound pressure levels without distortion
• Legendary Shure build quality for stage and studio use
• Standard 3-pin XLR connector
• LC version: supplied without a microphone cable

On drums and guitar cabinets

On a snare drum, the SM57 captures the crack and body of the drum while its cardioid pattern rejects much of the hi-hat and kit bleed arriving from behind the microphone. Placed close to a guitar cabinet, it delivers the midrange weight and pick attack that engineers expect, and small changes in position relative to the speaker cone give predictable control over brightness. The same qualities make it a reliable choice for toms, congas and brass instruments, where its response adds definition without extra equalisation work.

High SPL without complaint

Dynamic microphones do not need phantom power, and the SM57’s design handles extremely loud sources placed close to the capsule. That is why it can sit centimetres from a cranked guitar amplifier or a hard-hit snare all night without the distortion that would trouble more delicate microphones. In live sound, its controlled off-axis response also helps keep monitor feedback in check, so engineers can push a channel harder before problems start.

Build and handling

The body is dark grey enamelled die-cast steel, and the grille uses a polycarbonate and steel mesh construction designed for abuse. At 284 g it has the solid feel engineers associate with working microphones rather than delicate studio pieces. The microphone connects over a standard balanced XLR output, and this LC package includes the microphone, a stand adapter and a storage pouch, without a cable.

Beyond instruments

Although it is sold as an instrument microphone, the SM57 is also used for vocals, spoken word and amplifier re-amping where its presence lift helps a source cut through a mix. Studios routinely keep several on hand because one microphone covers so many daily tasks: today a snare, tomorrow a guitar cabinet, next week a brass section.

If a collection can hold only one general-purpose dynamic microphone, the SM57-LC is the industry’s standing answer: consistent, tough and useful on almost every source it meets.
