Earthworks M30 Matched Pair
Measuring Microphones in Cherry Wood Box

The Earthworks M30 is a very accurate microphone. It utilizes a very small, very accurate omni directional capsule, a carefully crafted stainless steel body and innovative circuitry to deliver time coherent response from 9Hz to 30kHz. 20 to 20kHz is not enough! This extended frequency response is essential for capturing sonic events accurately. In terms of the standard audio range the Earthworks M30 are typically well within 1dB from 20Hz to 20kHz.

Operating the Earthworks M30 is extremely simple. Using a good quality standard XLR mic cable connect the M30 to an active electronic microphone preamp which provides 48 volt phantom power with at least 10mA of current available. Adjust the preamp gain to the level required for your test equipment. The Earthworks M30 has extremely low handling noise and does not require a shock mount. All windscreens effect the higher frequency performance, so they are to be avoided. When needed, a small ball type intended for a 1/4" lavelier will do the job.
