Shure SM81-LC

The Shure 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.

SM81-LC - With windscreen, no cable. Phantom power required.

Product Features:

  • 0 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 impedances
  • 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
  • 1-year Manufacturer's warranty

Microphone Specifications

Microphone Type
This is the type of microphone included with the purchase of the item.

Wireless:All of these microphones can be used without the necessity of wires or cables to connect them. They usually come with a receiver that connects to the input device where the audio signal is being sent.

Shotgun: These microphones are suspended on a boom and are used primarily in video production and broadcasting.

Lavaliere: These microphones are clipped on to the lapel or tie of the talent for broadcast and video production audio.

Table Top: These microphones are designed with a built in stand or to be placed on a table top stand to be used for broadcasting and podcasting applications.

Headset: These microphones are to be worn on the head typically for live performance and theater production.

Handheld: These microphones are held in the hand and are used in a wide range of applications primarily vocals and public address.

Clamp On: These microphones attach directly on to an instrument.

Drum Package: These microphones are an all in one package for drums typically made of dynamic Kick, Snare, Tom, and a stereo condenser pair of overhead mics for Cymbals.

Polar Patterns
The polar pattern of a microphone determines how sensitive it is to receiving sounds as they arrive at different angles.
Cardioid
Transducer Type
The transducer type is the manner in which the audio signal is converted into an electrical signal.
Condenser
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20,000 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
-45 dB
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
78 dB
Output Impedance
This is the amount of impedance that the microphone allows.
150 ohms
Pad(s)
A pad is a term used for built in attenuation in a microphone or pro audio channel strip.
-10
Connection Type
This is the manner in which the microphone connects to the source unit. For wired microphones, this is the connector that directly connects the microphone to the mixer (or other input source unit). For wireless microphones, this is the connection that connects the microphones receiver to the mixer (or other input source unit).
