CMC 6 Uxt – the 40 kHz version
This version is indicated by the letters ”xt” engraved on the microphone’s output socket. It extends the frequency response of the axially addressed Colette capsules beyond 40 kHz.
CMC 6 is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording. More info
