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.
