Earthworks M50
High Definition Measurement Microphone

M50

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.

Features:

• 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
• 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
• Requires 48V Phantom Power
• Each M Series microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve
