Universal Audio was founded in 1958 by Bill Putnam Sr. as a maker of recording equipment. Putnam was the inventor of the modern recording console, the multi-band audio equalizer, and the vocal booth, and he was the first engineer to use artificial reverberation in commercial recording. Alongside his friend Les Paul, Putnam was also involved in the early development of stereophonic recording. Putnam started three audio product companies during his career: Universal Audio, Studio Electronics, and UREI. All three companies built equipment that remains widely used decades after their introduction, including the LA-2A and 1176 compressors, and the 610 tube recording console.
The current incarnation of Universal Audio was established in 1999 by Bill Putnam Sr.'s sons, James Putnam and Bill Putnam Jr. Universal Audio aims to faithfully reproduce classic analog recording equipment and to design new digital recording tools which capture the essense of vintage analog technology. The company now has more than 200 employees, and offices in Los Angeles, Colorado, and Amsterdam, and headquarters in Scotts Valley, California. A few miles away in Santa Cruz is the Universal Audio Custom Shop, where the classic analog gear is still hand-built, one unit at a time
