Earthworks M30 30kHz Omni Measurement Microphone
The Earthworks M30 is an omnidirectional measurement microphone with a staggering frequency response of 5Hz right up to 30kHz! The M30 ships standard with an elegant black protective case, ADP1 Calibrator Adapter and microphone clip. The M30 from Earthworks is ideal for applications such as foley recording, sound pressure and frequency measurements, and as room or ambient microphones in studio recordings. There is also a stereo matched pair available for the Earthworks M30. Earthworks have an impeccable reputation for constructing exceptionally accurate measurement microphones, at a very reasonable price.

Earthworks M30 PRODUCT FEATURES:
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.
M30 Feature Summary:
30kHz flat frequency response
Ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required
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
