About this listing
The Earthworks M23 Gen 2 Measurement Microphone continues the legacy of precision and reliability that made the original M23 a trusted tool in studios, live sound, and system calibration worldwide.Designed for engineers and acousticians who demand accuracy without compromise, the M23 Gen 2 captures every sonic detail with true-to-source clarity and extended frequency response — making it an essential reference for any acoustic measurement environment. Built with a machined stainless-steel body and IP54-rated durability, the M23 Gen 2 is engineered to perform in the field or the lab. With a flat response from 5 Hz to 23 kHz and an extended high-frequency reach up to 30 kHz, it delivers the accuracy required for real-world acoustic analysis, room tuning, and system alignment. Its omnidirectional polar pattern ensures consistent off-axis response, while ultra-low self-noise and high SPL handling preserve integrity across any dynamic range. Hand-calibrated and manufactured in the USA, the M23 Gen 2 exemplifies Earthworks’ precision engineering at its finest.Earthworks M23 Gen 2 Measurement Microphone FeaturesSecond-generation evolution of the classic Earthworks M23 measurement micUltra-flat frequency response (±1 dB) from 5 Hz to 23 kHzOmnidirectional polar pattern ensures uniform spatial accuracyExtended frequency reach beyond 30 kHz for detailed high-end responseHandles extreme SPL levels — up to 140 dB (P48) without audible distortionExceptionally low self-noise of 23 dBA for precise, wide dynamic range measurementsPrecision-matched sensitivity (-40 dBV/Pa, 10 mV/Pa ±2 dB) for consistency across systemsRugged stainless-steel housing with IP54 rating for dust and moisture resistancePowered by standard P48 (48 V) or P12 (12 V) phantom powerIdeal for acoustic analysis, room calibration, and loudspeaker alignment applicationsEach unit individually calibrated and includes printed calibration chartEarthworks M23 Gen 2 Measurement Microphone SpecificationsMicrophone Type: Pre-polarized condenserDiaphragm Size: 6 mmPolar Pattern: OmnidirectionalFlat Response Range (±1 dB): 5 Hz – 23 kHzFrequency Response (-3 dB): ≤ 3 Hz to ≥ 30 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: 5.5 × 0.86 in (138.6 × 21.8 mm)Weight: 0.28 lb (0.13 kg)Earthworks M23 Gen 2 Measurement Microphone IncludesEarthworks M23 Gen 2 Measurement MicrophoneMC1 Microphone ClipMic Stand Thread AdapterOMW2 WindscreenADP1 Calibrator AdapterCalibration Chart (individual performance data)Protective Carrying CaseManufacturer Warranty
