The Shure SM81-LC-X is a premium small-diaphragm condenser microphone renowned for its exceptional sonic accuracy, rugged durability, and versatility. Designed for studio recording, broadcasting, and live sound reinforcement, this unidirectional microphone features a cardioid polar pattern that isolates the primary sound source while minimizing off-axis noise and feedback. With a wide, flat frequency response of 20 Hz to 20 kHz, the SM81-LC-X delivers transparent, natural sound reproduction—making it a go-to choice for capturing acoustic instruments like guitars, pianos, cymbals, and drum overheads.
Engineered for precision, it offers low self-noise (16 dB A-weighted) and a high maximum SPL (146 dB with the -10 dB attenuator engaged), ensuring distortion-free performance across a wide dynamic range. The microphone includes a 3-position low-frequency filter (flat, 6 dB/octave, or 18 dB/octave roll-off) to reduce unwanted rumble or proximity effect, and a lockable 0 dB/-10 dB attenuator switch for handling loud sources like drums or amplifiers. Powered by 48 Vdc phantom power (operable down to 11 Vdc), it’s compatible with most mixers and audio interfaces.
Built with a vinyl-coated steel housing, the SM81-LC-X is tough enough for studio and stage use, with low RF susceptibility for clean audio in challenging environments. It weighs just 230 grams and measures 212 mm in length, shipping with a swivel adapter, foam windscreen, attenuator lock, and carrying case. Note that the “LC” designation means no cable is included—users must supply their own XLR cable.
From studio engineers recording delicate strings to live sound techs miking percussion, the SM81-LC-X excels in applications requiring clarity and reliability. Its small-diaphragm design ensures excellent transient response, while its consistent off-axis rejection makes it ideal for stereo miking setups. Since 1978, the Shure SM81 series has been an industry standard, and the SM81-LC-X upholds that legacy with professional-grade performance.
