Designed for uncompromising precision and reliability, it continues the legacy of the M-Series as the industry’s reference standard for accurate sound measurement since 1995.\u003c\/p\u003e \u003cp\u003eThis pre-polarized condenser microphone offers an exceptionally flat frequency response from 5 Hz to 30 kHz (±1 dB), ensuring faithful audio capture across the audible spectrum and beyond. With extremely low self-noise (23 dBA) and the ability to handle up to 140 dB SPL, the M30 G2 provides exceptional performance in both quiet studio environments and high-SPL live sound applications. Its updated sensitivity and reduced power consumption make it highly compatible with modern audio interfaces and measurement systems.\u003c\/p\u003e \u003cp\u003eBuilt with precision-machined stainless steel and rated IP54 for dust and moisture resistance, the M30 G2 is ready for demanding field use. Whether in laboratory-grade measurement setups or on-site sound system tuning, this microphone offers the accuracy and consistency professionals trust worldwide.\u003c\/p\u003e  \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e   \u003cli\u003e \u003cstrong\u003eExtended Frequency Response:\u003c\/strong\u003e Exceptionally flat ±1 dB from 5 Hz to 30 kHz for accurate sound measurement\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eHigh SPL Handling:\u003c\/strong\u003e Captures up to 140 dB SPL (48V phantom power) without distortion\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eOmnidirectional Pattern:\u003c\/strong\u003e True free-field reference for uniform off-axis response\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eLow Self-Noise:\u003c\/strong\u003e Just 23 dBA for ultra-clean measurement in quiet environments\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eReduced Power Consumption:\u003c\/strong\u003e Draws only 7.2 mA at 48V, improving wireless and multi-mic efficiency\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003ePrecision Engineering:\u003c\/strong\u003e Machined stainless steel housing with IP54 environmental rating\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eEnhanced Compatibility:\u003c\/strong\u003e Optimized 1 kHz sensitivity ensures consistent readings across audio interfaces\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Designed, tuned, and assembled in the United States for long-term reliability\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003cul\u003e   \u003cli\u003e \u003cstrong\u003eMicrophone Type:\u003c\/strong\u003e Pre-polarized condenser\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eDiaphragm Size:\u003c\/strong\u003e 6 mm\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003ePolar Pattern:\u003c\/strong\u003e Omnidirectional\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eFlat Frequency Range (±1 dB):\u003c\/strong\u003e 5 Hz – 30 kHz\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eLow Frequency Cutoff (-3 dB):\u003c\/strong\u003e ≤ 3 Hz\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eHigh Frequency Cutoff (-3 dB):\u003c\/strong\u003e ≥ 40 kHz\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eSensitivity:\u003c\/strong\u003e -40 dBV\/Pa (10 mV\/Pa) ±2 dB\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eA-weighted Self-Noise:\u003c\/strong\u003e 23 dBA\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eMaximum SPL (3% THD):\u003c\/strong\u003e 140 dB SPL (P48), 133 dB SPL (P12)\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003ePower Requirements:\u003c\/strong\u003e P48 (7.2 mA) \/ P12 (4.8 mA)\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eMinimum Load Impedance:\u003c\/strong\u003e 1 kΩ\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP54\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eConstruction:\u003c\/strong\u003e Machined stainless steel\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eDimensions (L × W):\u003c\/strong\u003e 7.0 × 0.86 in (17.8 × 2.18 cm)\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eWeight:\u003c\/strong\u003e 0.30 lb (0.14 kg)\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e USA\u003c\/li\u003e   \u003cli\u003e \u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years\u003c\/li\u003e \u003c\/ul\u003e  \u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e \u003cul\u003e   \u003cli\u003eCarrying Case\u003c\/li\u003e   \u003cli\u003eCalibration Chart\u003c\/li\u003e   \u003cli\u003eMC1 Microphone Clip\u003c\/li\u003e   \u003cli\u003eOMW2 Windscreen\u003c\/li\u003e   \u003cli\u003eADP1 Calibrator Adapter\u003c\/li\u003e   \u003cli\u003eMic Stand Thread Adapter\u003c\/li\u003e \u003c\/ul\u003e","brand":"AudioNest","offers":[{"title":"Default Title","offer_id":68077329678535,"sku":"ERTHWK-M30G2","price":524.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0820\/0575\/4055\/files\/1-earthworks-m30-g2_4dc6c2b9-5666-4ac1-a861-a4cabed1e39e.jpg?v=1793015500","url":"https:\/\/audionestt.shop\/products\/earthworks-m30-g2-30-khz-measurement-microphone","provider":"AudioNest","version":"1.0","type":"link"}
