United Recording Electronics Industries

Insulated from the recording studio changes, Universal Audio was thriving upstairs in the first Hollywood building under the new name United Recording Electronics Industries (UREI). The manufacturing and design company had acquired the patent rights to the electro-optical LA-2A leveling amplifier. UREI also acquired National Intertel, which became the Teletronix division. From this acquisition came technology which developed into the 1176 peak limiter in 1968, and the 1108 FET preamp.

Other well-received UREI products included the LA-4 electro-optical compressor limiter, the UREI Teletronix LA-3A electro-optical leveling amplifier and the 500-series UREI graphic equalizers.

By 1976, UREI had moved their manufacturing and service center to Sun Valley, California.
