Earthworks M50 is a professional measurement microphone intended for large room calibration. The ultra wide frequency response of 3Hz to 50kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems.The small element yields an omni-directional pattern resulting in a wide pick up area at the front and sides of the microphone capsule. The M50 ships with a microphone clip and a 1/2″” calibrator adaptor.
