Shure SM81 Instrument Mic

Precision Audio for Acoustic Instruments

The Shure SM81 is a high-quality, unidirectional condenser microphone renowned for its flat frequency response and versatile performance, making it an industry standard for capturing acoustic instruments in Australia. Ideal for studio recording, broadcasting, and live sound reinforcement, the SM81 excels on acoustic guitar, piano, cymbals, and other instruments, delivering sonic accuracy with minimal noise. Its rugged design and low RF susceptibility ensure reliable performance in any environment.

Crystal-Clear Sound for Professionals

Featuring a uniform cardioid polar pattern, the SM81 provides maximum off-axis rejection, isolating the sound source while minimizing feedback and background noise, perfect for live stages and untreated studios. Its wide frequency response (20 Hz – 20 kHz) and low self-noise deliver transparent, natural reproduction of acoustic instruments. A switchable low-frequency roll-off (flat, 6 dB, or 18 dB/octave) and a lockable -10 dB pad offer flexibility for capturing loud sources or taming proximity effect, ensuring pristine audio in any setting.

Durable and Stage-Ready

Built with Shure’s legendary durability, the SM81 features rugged vinyl-coated steel construction, making it field-usable across a wide range of temperatures and humidity conditions. The included foam windscreen reduces wind and plosive noise, while the swivel adapter simplifies positioning. Requiring phantom power (11–52 V DC), the SM81 integrates seamlessly with professional audio systems, making it a must-have for any studio or live sound engineer’s toolkit.
