SHURE SM-2 headset condenser microphone

SHURE SM-2 headset condenser microphone

SM2 in unidirectional microphone for close talking microphone moving coil type , frequency response of 50 to 15,000 Hz. Because of its noise reduction properties , it can be clearly identified close distance voice sounds weakened . Therefore , even in extremely noisy environments, it is not lost or masked speech signal . Microphone boom stand can be rotated in 155 degrees , so that it can be placed on the left or right side of the mouth. Locking thumb to prevent slipping or twisting the microphone . Close- talk microphone operation and unidirectional polar pattern reduces noise

Features:

Smooth , natural frequency response of the microphone voice

Microphone can be worn on the right or left , the rod holder can be rotated in 155 degrees

Microphone boom stand length within ( 31/ 2 inches ) in the 89 mm range adjustment

Built-in high-sensitivity receiver headphones can isolate the indoor noise and improve the clarity of reception

Fatigue can adjust the rotating earpiece with padded , improve user comfort and reduce the long-term use caused

Specifications:

Dynamic, close-talking

Frequency Response (8 mm, 5/16 inch) : 50 to 15,000 Hz

Polar Pattern : Cardioid (unidirectional ) response frequency , symmetrical about axis ?

Impedance: When connecting to a rating of 19 to 300 ohm microphone inputs Microphone rating impedance is 150 ohms ( impedance of 200 ohms ) .

Microphone sensitivity (1,000 Hz under close-talking ) : Open circuit voltage : 47.0 dBV / Pa * (4.5 mV)

· 1 Pa = 94 dB SPL

Hum Sensitivity ( usually ) : 1 millioersted field equivalent of 38.4 dB SPL

Polarity: Positive pressure on diaphragm produces positive voltage on the "red " lead ( as opposed to " black " lead )
