    Earthworks M50 50kHz Omni Measurement Microphone

    The Earthworks M50 is the most impressive measurement microphone in Earthworks M series. Capable of capturing sound frequencies from 3Hz - 50kHz. The M50 is an omnidirectional condenser with an elegant silver finish, and the package contents include a stylish wooden case, microphone clip and the Earthworks ADP1Calibrator Adapter. The M series of microphones from Earthworks offers incredible value given their price-point, craftsmanship and sonic capabilities. Ideal for working in Foley rooms, measurement applications and in the studio as ambient or spot miking. 

      • Earthworks M50 PRODUCT FEATURES:

        The M Series has become the accepted standard for affordable, reliable reference and measurement microphones that are accurate in the time domain and frequency response. They are remarkably stable with respect to temperature and atmospheric conditions and are optimized for clean, very fast impulse performance providing accurate wideband response with virtually no handling noise.

        M50 Feature Summary:
        50kHz flat frequency response
        Ideally suited for acoustical measurements that require extended frequency response, including high-end loudspeaker design and quality control, scientific research, measurements of ultrasonic or subsonic transducers, or any application where an extremely accurate free-field measurement microphone is required
        Our top of the line measurement microphone with extraordinary impulse response for those who have stringent requirements and demand the very best
        Provides laboratory grade accuracy
        Improved version of the SMAARTMIC™ previously offered by EAW
        Omnidirectional polar pattern
        Flat frequency response, fast impulse response and exceptional polar characteristics
        Used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others
