About Earthworks M30

The Earthworks M30 Omni directional High Definition Measurement Microphone (Matched Pair) is designed and calibrated for measurement purposes. It is a pre-polarized condenser microphone directly coupled to a wideband, low output impedance preamplifier. The M30 requires a standard 48V phantom power supply.

It features a linear free-field frequency response from 3Hz to 30kHz, very low handling noise, uniform polar pattern and very high SPL handling capabilities. Its unique circuitry excludes the trans-conductance of the input FET from the overall gain structure. This means the sensitivity remains very stable when the microphone is subjected to variations in ambient temperature. The M30 meets or exceeds ANSI Type 1 requirements.

Applications
Earthworks M30 is ideally suited for acoustical measurements sound system setup and troubleshooting, room acoustics or any application where an accurate free-field measurement microphone is required.

The M30 is simple to operate. Connect the microphone to a microphone preamplifier supplying 24-48V phantom power using a standard XLR microphone cable. Allow up to one minute for the microphone to settle. Plugging in the microphone "hot" will not damage the microphone and is actually preferred for faster settling. For optimum results point the M30 toward the sound source. This microphone has no removable parts.

Calibration
The microphone is calibrated at the factory at 1 kHz (therefore independent of any frequency weighting).
