Earthworks M 30 BX

The Earthworks M30BX is a battery powered measurement microphone with a built-in preamp.

The Earthworks M30BX is a very cost effective reference microphone for SMAART, MLSSA, Spectrafoo, TEF & RTA and all audio band measurements. It has a flat frequency response, fast impulse response and exceptional polar characteristics. The M30BX meets or exceeds ANSI Type 1 and applicable IEC 61094 requirements.

The Earthworks M30BX is ideally suited for on-location 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 and portability is important or a power source is not readily available.

The microphone body opens for replaceable battery access, with a battery life of 300 hours.

Each mic is delivered with its own calibration chart providing its individually measured open-circuit sensitivity for both gain positions, and the frequency response curve.

Electronic calibration files can be used to import the M30BX’s amplitude frequency response directly into your measurement system.
