OVERVIEW

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 requires a high microphone internal supply voltage derived from the Phantom power. 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. The input impedance of the microphone preamp being fed by the measurement mic should be as high as possible. Low supply current together with “a not” too low preamp input impedance reduces the voltage drop over the 6.8k supply chain resistors and results in both, a high internal supply voltage and highest mic output voltage possible. In addition to this, the microphone body/preamp accepts 60V of Phantom power as well as the newer P48H (high power) supply. The output is short circuit protected.

The iSEMic CPX12 series comes in a neutral stainless-steel design with a linear and extended frequency bandwidth. It is a high-SPL optimized recording and measurement mic with unmatched dynamics. The close-miking capability combined with a linear on-axis response in an extended frequency range makes it suitable for a wide range of applications in Speaker Manufacturing, Sound Reinforcement, SPL monitoring and Clean Sound Recording. Due to its qualities and modularity, it can be used as a reference microphone in acoustic test equipment.

It’s your application that counts.
