Shure SM81-LC Cardioid Condenser Instrument Microphone

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.

Cardioid polar pattern, uniform with frequency and symmetric about axis, providing maximum rejection and minimum coloration of off-axis sounds

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.

0 dB/10 dB lockable attenuator switch

Low RF susceptibility

Selectable low-frequency response: flat, 6 or 18 dB/octave rolloff

Rugged steel construction for durability. Field-usable over wide range of temperature and humidity conditions.

This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS.

Low noise and high output clipping level. Low distortion over a wide range of load impedances.

20 Hz to 20 kHz frequency response. Flat response curve for accurate reproduction of sound sources.
