The Ultimate in Audio Measurement

The M50 is a precision engineered 50kHz omnidirectional measurement microphone ideally suited for acoustical measurements including high-end loudspeaker design and quality control, scientific research, measurements of ultrasonic or subsonic transducers, or any application where an extremely accurate free-field measurement microphone is required.

The Pinnacle of Transparency

An ultra wide flat frequency response that extends from 3Hz to 50kHz and is flat throughout the entire spectrum. An omnidirectional polar response that is exceptionally consistent. A 140dB SPL rating without distortion and no handling noise.

Compatible With Your Favorite Measurement Software

Lightning fast impulse response and linear phase response make the M50 ideal for use with high-quality FFT-based real-time audio system measurement software like SMAART™, SIM™, REW™, Electroacoustics Toolbox™, FuzzMeasure™ and others, as well as for use in PA system alignment and loudspeaker design.

Electronic Calibration File

Every M50 is individually hand-tuned and tested and is delivered with its own printed frequency response chart. An Electronic Calibration File (ECF) is generated for each microphone during final testing, and can be downloaded free of charge after product registration.

The M50’s measurement s confirm the manufacturer’s claims —moderately low noise, accurate sound pressure measurement, even and extended frequency response, and a good omnidirectional polar pattern. There are competitive microphones that do better in one or two of these areas, but there are none that I’m aware of that offer this particular balance of virtues.
