The M23R from Earthworks is a reference microphone for SMAART, MLSSA, Spectrafoo software, TEF and RTA, and all audio-band measurements. It has a flat frequency response, can handle high SPL values, and exhibits a low amount of self-noise.
The company is well known and respected for its reliable reference and measurement microphones. The M23R offers the same frequency response, polar pattern characteristics, and sensitivity values across its entire operating range. Furthermore, the mic can withstand a wide range of extreme temperatures, making it durable.
Small element provides an accurate omnidirectional pattern with an even, coherent response at the direct and off-axis sections of the microphone capsule
Wide, linear frequency response accurately captures audio signal and reproduces the slightest nuance with great detail
Uncolored, flat signal results in accurate room calibration for indoor and outdoor application
Requires 48V phantom power to operate
Every M23R has the same frequency response and sensitivity, matched to within A±0.5 dB across the entire operating frequency range (3 Hz to 23 kHz).
