      Klassikeren til hihat og overhead – eller til kor.

      Shure SM81LC er en klassisk kondensatormikrofon for instrumenter. Bredt frekvensområde 20-20000 Hz gjør den egnet til variert studio- og PA-bruk. SM81LC har stillbart basskuttfilter. En klassiker til overhead!

      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 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

      Condenser (electret bias)

      Frequency Response
      20 to 20,000 Hz

      Polar Pattern
      Cardioid (unidirectional) response-uniform with frequency, symmetrical about axis

      Output Impedance
      Rated at 150 ohms (85 ohms actual)
      Recommended minimum load impedance: 800 ohms (May be used with loads as low as 150 ohms with reduced clipping level)

      Output Configuration and Connector
      Balanced, transformer-coupled output; male XLR connector

      Sensitivity (at 1,000 Hz)
      Open Circuit Voltage: -45 dBV/Pascal (5.6 mV
      (1 Pascal = 94 dB SPL)

      Clipping Level (at 1,000 Hz)
      800 ohm Load: -4 dBV (0.63 V)
      150 ohm Load: -15 dBV (0.18 V)

      Total Harmonic Distortion
      Less than 0.5% (131 dB SPL at 250 Hz into 800 ohm load)

      Maximum SPL (at 1,000 Hz)
      800 ohm load: 136 dB (attenuator at 0) 146 dB (attenuator at -10)
      150 ohm load: 128 dB (attenuator at 0) 138 dB (attenuator at -10)

      Hum Pickup
      -3 dB equivalent SPL in a 1 mOe field (60 Hz)

      Self-Noise (equivalent sound pressure levels; measured with true rms voltmeter)
      16 dB typical, A-weighted
      19 dB typical, weighted per DIN 45 405

      Signal-to-Noise Ratio
      78 dB (IEC 651)* at 94 dB SPL
      *S/N ratio is difference between 94 dB SPL and product's equivalent self noise (SPL A-weighted).

      Overvoltage and Reverse Polarity Protection
      Max. external voltage applied to pins 2 and 3 with respect to pin 1: +52 Vdc
      Reverse polarity protection: 200 mA max. (diode-clamped)

      Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3

      Cartridge Capacitance
      54 pF

      Low Frequency Response Switch Positions
      Flat; -6 dB/octave below 100 Hz; -18 dB/octave below 80 Hz

      Attenuator Switch Positions (Lockable)
      0 or -10 dB

      Supply Voltage: 11 to 52 Vdc, positive, pins 2 and 3
      Current Drain: 1.2 mA max.

      Environmental Conditions
      Storage: -29 degrees to 74 degrees C (-20 degrees to 165 degrees F)
      Operating: -6.7 degrees to 49 degrees C (20 degrees to 120 degrees F)

      Storage 0 to 95% relative humidity at room temperature (72 degrees to 80 degrees F, 22 degrees to 27 degrees C)

      Steel construction with vinyl metallic paint finish and stainless steel screens
