Aphex

Sun Valley, California

Aphex was founded in 1975 by Marvin Caesar in Los Angeles to supply the Aural Exciter to studios - on a rental basis only. The Company name reflected the product: the Aural Perception Heterodyne EXciter 

Eventually, the broadcast community began using the Aural Exciter, and other products - including the Compellor - designed by Donn Werrbach - to enhance the audio chain in radio stations. 

Caesar sold the company in 2000 to David Wiener, who then sold the line to Rode Microphones.
