Beskrivning
ECM-90BC
Ultra-miniature, omni-directional electret condenser lavalier microphone designed for quality-critical applications in ENG, Studio, EFP, and Location Sound applications. Dual diaphragm design contributes to high sensitivity, wide dynamic range, and low noise. Generous diaphragm mounting architecture radically reduces common cable noise associated with lavalier microphone designs. Flat and wide frequency response (20Hz – 20kHz) provides natural sound reproduction. Water resistant design maintains sound clarity in almost any application or environment. Shielded for use with digital wireless transmitters.
