ASTATIC - 9000 - Power Module 9000 - Microphone In/Out
Astatic Corp was based on Conneaut Ohio for many years. Although they primarily produced microphones for voice-frequency communications work, they also made higher-fidelity models which are much less common. The company reorganized as Omnitronics LLC in 2000, and later combined CAD, Astatic and Omnitronics under the CAD Audio brand.
Model PM-9000 power module houses microphone electronics and features a superior low noise transformerless design for optimum frequency response. The PM-9000 power module also includes a switchable 12dB per octave high pass filter. The PM-9000 can be mounted either with 4 mounting screws or double-sided foam tape.
