The UMIK-2 is a significant upgrade in performance and functionality over the UMIK. A larger 1/2-inch microphone capsule provides a lower noise and a lower distortion, which is preserved by the 32-bit ADC (analog-to-digital convertor) built into the microphone shell. Furthermore, sample rates are selectable from 44.1 to 192 kHz for compatibility with the widest possible range of measurement and recording software.
