CAD Audio originally took shape as the Astatic Corporation in 1931, founded by C.M. Chorpening and F.H. Woodworth, two ham radio operators who needed a static-free microphone for their transmitters. They worked with local engineers to develop the company’s first crystal radio microphone, the model D-104.
Now known as Astatic Commercial Audio Products, the company has evolved into a successful manufacturer of commercial microphones for a wide variety of industrial applications. Astatic microphones can be found in restaurants, airports, churches, schools, and corporate boardrooms worldwide. Their ongoing success is based on Variable Pattern Technology available in hanging, gooseneck, and boundary types. The pick-up patterns can be controlled on the microphone, by using the remote pattern control box or through some of the industries’ most popular digital signal processors.
