Earthworks M50 Measurement Microphone
The M50 pushes Earthworks' measurement line to 50 kHz, for acoustical measurement, loudspeaker design, and scientific research work that needs headroom well above the audible band. Temperature-compensated electronics keep the response repeatable from a cold rig to a hot stage.
Its omnidirectional pattern stays uniform across the band, and it runs on standard 24 to 48 V phantom power over a 3-pin XLR (pin 2+).
