Measurement Microphone
EMC-999 measurement microphone
Superlux measurement series microphone for high sensitivity and low noise, very flat frequency response, to provide accurate measurement data and clear recordings. ECM-999 is a non-directional free-field measuring microphone. It uses 1/4 inch pre-polarized condenser Ondo, highly reliable circuit professionally designed microphone with high stability, low distortion and low noise. Especially the extremely flat frequency response curve is one of the preferred microphone audio analysis systems and various types of special recordings.
