Modern Prepolarized Precision Condenser Microphones & Preamplifiers
Modern prepolarized microphones are designed with newer technology than traditional externally polarized microphones. Prepolarized microphones have many advantages over the externally polarized models. They use ICP® power circuitry invented for sensors by PCB®. By applying a polymer coating to the top of the backplate and embedding a charge on it, expensive 200V power supplies can be eliminated and 2-20 mA constant current supplies or signal conditioners can be used as the power source.

Directional Microphone
MI-8100
MI-8100 is a shotgun type directional microphone which sharply catches the intended sound. This directional microphone is helpful for the removal of background noise in the simple sound source exploration and in abnormal sound detection. Flat frequency characteristic from 50 Hz to 20 kHz and sharp detection with high S/N ratio provide high sensitive detection of various sound coming from the specific direction. By combining the acoustic vibration monitor BL-1100, only the intended frequency or sound is focused and caught clearer.

Microphone Arrays
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.
