Shure SM81, Condenser Studio Microphone@+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.@+@+, Cardioid directivity for maximum isolation of the signal source and reduced background noise, High quality, permanently polarised condenser microphone, Linear frequency response for precise sound reproduction, Low inherent noise and high overdrive protection, Distortion-free recordings even at high sound pressure, Low sensitivity to interference at high-frequencies, 3-Step switchable high-pass filter: Linear, 6 or 18 dB / octave reduction, Switchable 10 dB attenuation, Phantom power in accordance with DIN 45 596 with voltage from 12 to 48 V, Robust steel version, Can be used even under extreme temperature and humidity conditions, Frequency range: 20 Hz / 20 kHz, Output impedance: 85 Ohm, Sensitivity: -45 dBV / Pa (5.62 mV), Total Harmonic Distortion (131 dB SPL at 250 Hz, 800 Ohm load): < 0.5 %, Maximum sound pressure (at 1 kHz, 800 Ohm load): 136 dB SPL, Windshield and microphone clamp included
