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.

Urei LA4 as a gain stage for microphone

Forums

Noobie here. yes, you have endured one novice question before and I ask for your patience again. . Have any of you ever used the gain in a vintage compressor like the LA4 to preamp a mic signal? I did this the other night as my Ward Beck's aren't powered yet and I had to test a new reverb so I ran my tube mic into the Urei and then to the reverb then to an XLR into Pro Tools.

Urei 539

So i have two 27 band (odd?) urei 539s. They have terminal blocks on the back, however there are also 1/4" jacks. The manual i found doesn't indicate they have them so i'm thinking it was a custom job. So i hooked them up with unbalances TS cables and they wouldn't process, they just passed the audio through. Could it be that i must use TRS?
