Microphone preamplifier
PRE-01
-
The microphone preamplifier PRE-01 has been designed to match Audiomatica’s microphones MIC-01, MIC-02 andMIC-03. It is particularly useful when the microphone has to be operated far from the analyzer or when weighted measurements are needed. PRE-01 powers the microphone connected to its input with an 8.2V phantom supplyand adds a selectable weighting filter (A or B or C); also available there is a 20 dB gain stage

Low Noise Prepolarized Microphone
378A04
-
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

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.

Measurement Microphones
-
The microphone bodies contain the preamplifier. They combine high dynamic range and wide frequency range with low noise. These measurement microphones connect via the ASD Cable to the XL2 Audio and Acoustic Analyzer, e.g. for measurements at remote locations or to reduce acoustic reflections.

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.
