EARTHWORKS / M30

EARTHWORKS measurement condenser microphone. Resistant to temperature and atmospheric changes, it can measure a wide frequency range. Recommended for sound field measurement and the development, evaluation, and research of acoustic equipment. The popular ""M=Measurement"" series is also used by professional engineers and acoustic researchers. It eliminates handling noise and provides precise measurements. Includes a dedicated microphone holder.
