The microphone is a combination of the CPX12 series microphone preamp body and the FP1212 high SPL microphone cartridge. It is a modular design ready for other ½“ or ¼“ capsules to be combined with. The preamp is a special high SPL compliant design. High SPL mean high microphone internal supply voltage. Due to the nature of Phantom Power (48Volts over 6.8k resistors) the preamp has to have a very low power consumption with a high slew rate and low impedance drive.
