EARTHWORKS _ M30BX

M30BX

30kHz Battery Powered Measurement Microphone

The M30BX is a cost effective measurement microphone intended for large and small room calibration. The ultra wide frequency response of 9Hz to 30kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems. The small element yields an omni-directional pattern resulting in a wide pick up area at the front and sides of the microphone capsule.

Description

The M30BX is a precision engineered battery-powered 30kHz omnidirectional measurement microphone 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.

Performance

Designed for remote use, the M30BX body opens for replaceable battery access, with a battery life of 100 hours. This M30BX requires 6V Lithium or 4 LR44 alkaline batteries.

The M30BX’s audio performance is unparalleled. It has a flat frequency response that extends from 9Hz to 30kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion and no handling noise. With temperature compensated electronics the M30BX was built to deliver repeatable results no matter what the environment.  

Extremely fast impulse response and linear phase response make the M30BX ideal for use with 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 M30BX 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.
