Shure SM27 Professional Large Diaphragm Condenser Microphone

Versatile Studio and Stage Audio Capture

The Shure SM27 Professional Large Diaphragm Condenser Microphone is a rugged, side-address cardioid condenser microphone designed for exceptional audio capture in both studio and stage environments across Australia. Known for its low self-noise, neutral tone, and high SPL handling, the SM27 is a versatile choice for recording vocals, acoustic instruments, guitar amps, and drums, making it ideal for musicians, podcasters, and sound engineers. Its durable construction and professional features ensure reliable performance at a competitive price point.

Neutral and Detailed Sound

The SM27 features a 1-inch, low-mass Mylar® diaphragm with a cardioid polar pattern, delivering a flat, neutral frequency response (20 Hz – 20 kHz) that captures vocal and instrument nuances with clarity and minimal coloration. Its low self-noise (9.5 dB SPL A-weighted) and high max SPL (138 dB, 153 dB with -15 dB pad) make it suitable for both delicate acoustic recordings and loud sources like drum overheads or guitar cabinets. The microphone includes a 3-position low-frequency filter (flat, 80 Hz, 115 Hz) to reduce rumble or proximity effect and a switchable -15 dB pad for handling high-SPL sources without distortion. The Class-A, transformerless preamplifier ensures transparency, fast transient response, and minimal distortion, while three-layer mesh pop protection reduces wind and breath noise.

Durable and User-Friendly Design

Built with Shure’s legendary durability, the SM27 features a robust metal construction and a steel-mesh grille to withstand the rigors of studio and live use. Its integral shockmount reduces handling and stand noise, and the included A32M ShureLock® swivel adapter (SM27-SC model) ensures secure positioning. The SM27 is equally effective in home studios, as it’s less sensitive than high-end condensers like the KSM44, making it forgiving in untreated rooms. Requiring 48V phantom power, it connects via XLR and is praised for its ease of use, requiring minimal setup. The SM27-SC includes a zippered carrying pouch, while the SM27-LC (no shockmount) is a more budget-friendly option. Users note its value as a step up from entry-level condensers and a reliable alternative to the SM7B for quieter environments.
