The design of the ECM-66B
yields clean, natural reproduction of musical instruments while maintaining excellent isolation from the acoustic environment. Unlike most miniature microphones, this Sony ECM-66B mic has a uni-directional polar pattern, carefully contoured for better control of feedback. The higher voltage supplied to the Sony ECM-66B microphone by the built in DC to DC converter increases the maximum input sound pressure level to an amazing 130 dB SPL.

This special construction of Sony ECM-66B also complements the electret condenser design, resulting in excellent transient response and thus better tonal quality. For added versatility, the ECM-66B can be powered by a single AA battery or external 48 VDC. The battery on/off switch on the power supply helps save the battery. An LED illuminates to show battery condition when power is turned on. A uni-directional miniature microphone developed specifically for recording musical instruments and voice when superb rejection of the ambient sound is desirable, the ECM-66B will make a welcome addition to your microphone arsenal.
