Earthworks M23 Gen 2 - Omni Measurement Microphone

Earthworks M23 Gen 2 - Omni Measurement Microphone

The Earthworks M23 G2 is a high-performance free-field reference microphone designed for acoustical measurement applications such as sound system tuning, room acoustics, loudspeaker design, and SPL measurement. Exceptional audio performance, roadworthy stainless steel construction and XLR output have made Earthworks M-Series microphones the ideal reference for the Professional Audio world since 1995.
Each microphone comes with its own individual calibration chart showing frequency response curve, 1 kHz sensitivity and 250 Hz sensitivity.

In the box:

• Microphone
  
• Protective Case
  
• Individual Calibration Chart
• MC1 Microphone Clip
  
• ADP1 1/2” Calibrator Adapter

M23 G2 Enhancements

Reduced Phantom Power

Consumption 48 Volt Phantom Power (P48) current consumption is now 7.2 mA (reduced from Gen 1’s 10 mA). This increases wireless transmitter battery runtime, as well as adding compatibility with certain audio interfaces, especially when a large number of microphones are used.

Reduced 1 kHz Sensitivity

1 kHz sensitivity has been reduced to -40 dBV/Pa (10 mV/Pa) for better compatibility with some commonly used audio interfaces that cannot handle higher input signal levels (above 10 dBV). This is important for SPL measurement and monitoring, where the entire input signal chain (microphone, preamp, interface) should be able to handle 140 dBSPL without clipping.

More Compact Form Factor

M23 G2 is a little over an inch and a half (4 cm) shorter than Gen 1, taking up less storage space and weighing less. The iconic and proven tapered tip design remains the same as Gen 1, with the length removed from the body section.

Carrying Case and Windscreen Included M23 G2 microphones

M23 G2 microphones ship with a roadworthy carrying case and an OMW2 windscreen.
