Earthworks M23 Measurement Microphone (9Hz – 23kHz)
ไมโครโฟนสำหรับการวัดจูนเสียง Earthworks M23 เป็นไมค์ที่ตอบสนองย่านความถี่ตั้งแต่ 9Hz – 23kHz flat frequency response มีรูปแบบการรับเสียงแบบ Omnidirectional polar pattern, Handles up to 140dB SPL without distortion, Improved version of the SMAARTMIC™ previously offered by EAW
The Earthworks M30 is a precision engineered 23kHz omnidirectional measurement microphone ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required.
Known for its reliable performance, the M23 delivers unparalleled audio results at an affordable cost. It has a flat frequency response that extends from 3Hz to 23kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion and no handling noise.
Immune to most temperature and atmospheric fluctuations, the M23 delivers reliable and repeatable results in any environment.
Extremely fast impulse response and linear phase response make the M23 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.
Every M23 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.
