About this listing
The Earthworks M30 Gen 2 Measurement Microphone sets a new benchmark for precision, consistency, and reliability in acoustic measurement.Designed for critical analysis, calibration, and system tuning, the M30 Gen 2 delivers a remarkably flat frequency response and fast impulse performance for true-to-source accuracy. Whether used in professional audio analysis, loudspeaker design, room tuning, or environmental acoustics, the M30 Gen 2 captures every detail with laboratory-grade precision. Building on the legacy of the industry-standard M30, the Gen 2 version refines every aspect of performance — extending response from 3 Hz to 40 kHz, reducing self-noise to 23 dBA, and increasing maximum SPL to 140 dB (with P48). Its machined stainless-steel body and IP54 rating ensure durability in any environment, while its omnidirectional, pre-polarized condenser capsule provides consistent on-axis and off-axis accuracy. Hand-tuned and individually calibrated, each M30 Gen 2 is built in the USA to Earthworks’ uncompromising standards.Earthworks M30 Gen 2 Measurement Microphone FeaturesNext-generation version of the renowned Earthworks M30 measurement micUltra-flat frequency response (±1 dB) from 5 Hz to 30 kHz; usable 3 Hz to 40 kHzOmnidirectional polar pattern for uniform and accurate spatial responseHandles extreme SPL – up to 140 dB (P48) without distortionExceptionally low self-noise of 23 dBA ensures wide dynamic range and clarityPrecision-matched sensitivity (-40 dBV/Pa, ±2 dB / 10 mV/Pa)IP54-rated stainless-steel body provides superior protection and longevityWorks with standard P48 (48 V) or P12 (12 V) phantom powerIdeal for system calibration, loudspeaker alignment, and RTA applicationsIndividually calibrated and delivered with a printed calibration chartEarthworks M30 Gen 2 Measurement Microphone SpecificationsMicrophone Type: Pre-polarized condenserDiaphragm Size: 6 mmPolar Pattern: OmnidirectionalFlat Response Range (±1 dB): 5 Hz – 30 kHzFrequency Response (-3 dB): ≤ 3 Hz to ≥ 40 kHzSensitivity: -40 dBV/Pa (10 mV/Pa) ± 2 dBSelf-Noise (A-Weighted): 23 dBAMaximum SPL (3% THD): 140 dB @ P48 / 133 dB @ P12Power Requirements: P48 (7.2 mA) / P12 (5.3 mA) phantom powerMinimum Load Impedance: 1 kΩIP Rating: IP54 (dust and splash resistant)Construction: Machined stainless steelDimensions: 7.0 × 0.86 in (177.8 × 21.8 mm)Weight: 0.30 lb (0.14 kg)Earthworks M30 Gen 2 Measurement Microphone IncludesEarthworks M30 Gen 2 MicrophoneMC1 Microphone ClipMic Stand Thread AdapterADP1 Calibrator AdapterOMW2 WindscreenCalibration Chart (certificate of individual calibration)Protective Carrying CaseManufacturer Warranty
