EARTHWORKS _ M50
M50
50kHz Measurement Microphone
The M50 is a professional measurement microphone intended for large room calibration. The ultra wide frequency response of 3Hz to 50kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems.
-
3Hz – 50kHz flat frequency response
-
Omnidirectional polar pattern
-
Handles up to 140dB SPL without distortion
- 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
- 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
