Shure Wired Microphone SM81-LC Shure Wired Microphone SM81-LC Description: The Shure Model SM81 is a high-quality, unidirectional condenser microphone designed for studio recording, broadcasting, and sound reinforcement. Its wide frequency response, low noise characteristics, and low RF susceptibility have made it a standard for applications involving acoustic instruments, especially guitar, piano, and cymbals. The SM81 is ruggedly constructed. It operates on phantom power and performs over a wide range of temperatures and humidity conditions. It is furnished with a swivel adapter, attenuator-switch lock, foam windscreen, and case for carrying and storage. Other accessories are available. Shure Wired Microphone SM81-LC Features: 20 Hz to 20 kHz frequency response Flat response curve for accurate reproduction of sound sources Low noise and high output clipping level Low distortion over a wide range of load Cardioid polar pattern, uniform with frequency and symmetric about axis, providing maximum rejection and minimum coloration of off-axis sounds Low RF susceptibility Selectable low-frequency response: flat, 6, or 18 dB/octave rolloff 0 dB/10 dB lockable attenuator switch Phantom powering (DIN 45 596 voltages of 12 to 48 Vdc) Rugged steel construction for durability Field-usable over wide range of temperature and humidity conditions Shure Wired Microphone SM81-LC Specification: Type: Condenser (electret bias) Frequency Response: 20 to 20,000 Hz Polar Pattern: Cardioid (unidirectional) response uniform with frequency, symmetrical about axis, 10 kHz Output Impedance: Rated at 150 ohms (85 W actual) Recommended minimum load impedance: 800 W (May be used with loads as low as 150 W with reduced clipping level) Output Configuration and Connector: Balanced, transformer-coupled output; male XLR connector Output Level (at 1,000 Hz): Open Circuit Voltage s45 dBV/Pascal (5.6 mV)(1 Pascal = 94 dB SPL) Open Circuit Voltage s65 BV/mbar (0.56 mV)(1 mbar = 74 dB SPL) Clipping Level (at 1,000 Hz): 800 W Load s4 dBV (0.63 V) 150 W Load s15 dBV (0.18 V) Total Harmonic Distortion: Less than 0.5% (131 dB SPL at 250 Hz into 800 W load) Get your Shure Wired Microphone SM81-LC Today !!!
