C/M Laboratories, co-founded by Wayne Chou and Nick Morris, collaborated with Rudy Bozak, in the mid-1960s on the construction of basic mono mixers and power amplifiers. C/M Labs designed the CMA-10 mixer intended for orchestral sound reinforcement; it was produced in small quantities. C/M Labs also designed and built amplifiers and other integrated electronics for Bozak and used Bozak speakers to test their gear. In 1968 Bozak brought these electronic products into the Bozak factory and developed them further. The CMA-10-2 and 10-2DL mixer was designed at Bozak for sale to discotheques.
