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.
CAD (Conneaut Audio Devices) Professional Microphones was initially formed in 1988 as the Pro Audio division of the company to design and manufacture microphones for the recording and live sound markets, segments not served by Astatic. Initially, CAD introduced a revolutionary servo circuit console and breakthrough processing products, then went on to develop a series of innovative and cost-effective high performance studio microphones. These included the highly acclaimed E100, E200 and E300 Equitek Series mics that literally defined the project studio revolution of the late 1980s and early 1990s.
