In the 1970s Dorren was the director of research for Quadracast Systems, located in San Mateo, California. While in that position he made a prediction of sorts that with Discrete CD-4 records that only a single inventory would be required. He was the inventor of the QSI system that sparked up interest in quadraphonic broadcasting.

At the 26th annual conference, he hosted a segment in the Xytar room on how to make home recordings sound professional.
