Features

Cardioid condenser instrument microphone offers a wide frequency response and low self-noise. Features include flat response curve, low noise and high output clipping level, low distortion over a range of load impedances, and low RF susceptibility.

The Shure SM81 is a high-quality, directed condenser microphone with cardioid directivity designed for studio recording, broadcasting, TV recordings and public addressing. Its very linear, wide frequency range, low inherent noise and low noise sensitivity at high-frequencies, have made the SM81 the standard for recording acoustic instruments such as guitar, piano and drums. This extremely robust microphone operates on phantom power and performs reliably over under extreme temperatures and humidity conditions. The SM81 is equipped with a three-way switchable high-pass filter and 10 dB attenuation. Foam windscreen, and case for carrying and storage are included.
