The M30BX is a battery powered version of the M30. The M30BX delivers the same calibrated 30kHz performance as our M30 reference mic without the need for phantom power. It is powered by a single AA cell which will last 1500 hours of time plugged in. An internal switch allows 14dB of gain. If your sound card has any gain at all, and the sound level is even moderately loud, the output of the M30BX will be enough that you won't need an external preamp. The M30BX is a handy and powerful tool for laboratory, field and production measurements.

The M30BX is also superb for recording. A matched pair of the M30BX will transparently capture the all the subtle details of concerts, recitals, rehearsals, lectures, interviews, nature sounds and sound effects without the need of carrying extra battery packs or phantom power supplies. The M30BX matched pair comes with a pair of XLR to RCA female adapters, so it is a simple matter to adapt two mics into a stereo 1/8" connector which is the common input on mini disc recorders. With the 14dB pain switch on the M30BX will drive most semi pro line level inputs as long as the music is moderately loud. If you need to gather sounds in the field away from electrical power the M30BX is a powerful and unique field production fool.
