Earthworks M50 50kHz Omni Measurement Microphone

Omni Measurement Microphone - 3Hz to 50kHz (mic clip & ADP1 adapter included)

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.

• 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
• 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
• Electronic Calibration File available
• Operating Temp Range: -20 deg C to +60 deg C ( -4 deg. F to 140 deg. F)
• Storage Temp Range: -20 deg C to +50 deg C ( -4 deg. F to 122 deg. F)
• Humidity: Up to 90%
• Re-calibration recommended every five (5) years

Earthworks M Series measurement microphones have become the accepted standard for reliable measurement and reference. They are accurate in the time and frequency domain and have exceptionally uniform polar response. They feature flat free-field frequency response, fast impulse response, and are remarkably stable with respect to temperature changes, meeting or exceeding Type 1 specifications. Our M Series measurement microphones are used and recommended by SMAART™, MLSSA™, Spectrafoo™, TEF™, RTA in addition to acoustic measurement systems manufactured by dbx, Rational Acoustics, DEQX and others.

Consultants, Acousticians, as well as Industrial and Research Laboratories throughout the world have sought after the extremely wide frequency range of the Earthworks M50. In addition, they have great respect for the near-perfect polar response of this microphone. The M50 provides a frequency response from 3Hz to 50kHz, and will handle 140dB SPL. For those looking for a premium “top of the line” measurement microphone designed to exacting standards, the Earthworks M50 is it.

The Earthworks line of measurement microphones (with exception to the M30BX, which is battery operated) require standard 48V phantom power and up to 10mA of current (which is within the industry phantom power standard). 10mA of current is required to supply our high current, bipolar Class A amplifier within the microphone that is made with all discrete components, with no capacitors in the signal path providing excellent phase response. This also allows the microphone(s) to feed long signal lines up to 300 feet (91m) and maintain the full frequency response of the microphone at the other end of the line, without any loss in high frequencies.

The M50 comes in a protective carton with a custom die-cut foam insert and its own individual calibration chart. For those who desire calibration files to interface with their software, these are available at no cost. In addition, any number of microphones can be matched for a nominal fee. The M50 requires standard 48V phantom power for operation.

The M50 is the perfect choice for those who desire the utmost in precision, the widest in frequency response and superb polar response in an expertly manufactured precision measurement microphone. The M50 can be used in a wide variety of environments and will withstand the rigors of the road due to its robust design. The M50 is used in every critical environment from the most elegant of research laboratories to the recording of animal and bird sounds deep in the African jungle.
