Overview of Earthworks M30BX - Battery-Powered Measurement Microphone
The M30BX Battery-Powered Measurement Microphone from Earthworks is a measurement microphone with an omnidirectional polar pattern for on-location acoustical measurements such as loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or other applications where a free-field measurement microphone is required and a power source is not available. The M30BX body opens for access to a replaceable battery which will power the unit for 300 hours of operation. It requires a 6V lithium battery (included) or four LR44 alkaline batteries. The battery is automatically powered On or Off when the XLR connection is inserted or removed, eliminating the need for a power switch and preserving battery life. Featuring a flat frequency response that extends from 9 Hz to 30 kHz, the M30BX microphone is equipped with a fast impulse response and linear phase response. This makes it suitable 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. Additionally, every M30BX Battery-Powered Measurement Microphone is individually hand-tuned and tested and includes a 1/2" calibrator adapter, an XLR to RCA adapter, and an MC3 microphone clip.Music City Canada is an authorized reseller for Earthworks products.
