Product Description
Earthworks’ M50 measurement microphone has become an industry standard for reliable, high fidelity acoustical measurement. These reference microphones are optimized to have a neutral, uncolored response, capturing fast transients and accurate wide-band frequency response with virtually no handling noise. Stable with respect to temperature and atmospheric conditions, the Earthworks M50 creates transparent recordings both indoors and outdoors. These high definition microphones offer exceptional accuracy for critical recording and room calibration.
Features:
- Ideal for room calibration applications in any sized acoustic space.
- Ideal 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
- Provides laboratory grade accuracy
- 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
- Meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements
- Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve
