Description
Speaker calibration; room acoustic measurement; sound system setup; any of these scenarios and more can be undertaken with the help of the M23 omni measurement microphone from Earthworks. Crafted from durable materials, the mic offers low handling noise, is rated at 140dB SPL and can withstand harsh environmental settings.
Use with Industry Software
The M23 can be used in harmony with FFT-based real-time audio system measurement software (such as SMAART, REW, SIM, FuzzMeasure and Electroacoustics Toolbox etc). This is due to a linear phase response and super quick impulse response. It can even be used for loudspeaker design and the alignment of your PA system.
Hand-tuned & Tested
Each mic is both hand tested and hand tuned. It comes with a printed frequency response chart too.
