Earthworks M30 Omnidirectional Condenser Measurement Microphone Up to 30kHz

The M30 works with any high-quality FFT-based real-time audio system measurement software, like SMAART™, SIM™, REW™, Electroacoustics Toolbox™, FuzzMeasure™ and others, as well as for use in PA system alignment and loudspeaker design.
Every M30 is individually hand-tuned and tested and is delivered with its own printed frequency response chart. An Electronic Calibration File (ECF) is generated for each microphone during final testing, and can be downloaded free of charge after product registration.

Features:
Cost effective measurement microphone
Ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required
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
