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.


More recent CAD developments include the updated versions of the affordable, high quality CAD drum microphone packs; the Stage4, Stage7 and Touring7 Premium. CAD Audio has also added the new U9 MiniMic to its already versatile line of USB microphones, three new studio headphones the Sessions MH510 studio monitor headphone and the DH100 drummer isolation headphones, and the E100S large diaphragm condenser mic, the quietest LDC mic available on the market today, an evolution of the company’s groundbreaking Equitek Series studio microphone.
