Description
Reference-grade Omnidirectional Small-diaphragm Condenser Measurement Microphone
The M23R 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.
Infinitely Matched
Every M23R has the same frequency response and sensitivity - matched to within +/- 0.5dB across the entire operating frequency range (3Hz to 23kHz).
Infinitely Flexible
Build your own matched array of reference microphones at your own speed. Simply add more M23Rs whenever you need them. They'll match tomorrow or ten years from now.
Consistent Results Across Space & Time
Start doing multi-mic measurements or equip new teams at any time with confidence that all of their reference microphones match.
