Arrow Manual Universal Audio History 254
Re-founded in 1999
Universal Audio was re-founded in 1999 by Bill’s sons, James Putnam and Bill Putnam 
Jr., with two main goals: to faithfully reproduce classic analog recording equipment in 
the tradition of their father; and to design new digital recording tools in with the sound 
and spirit of vintage analog technology. To that end, Universal Audio employs the world’s 
brightest DSP engineers and digital modeling authorities to develop our award-winning 
UAD Powered Plug-Ins platform. Featuring the most authentic analog emulation plug-ins 
in the industry, our DSP gurus work with the original hardware manufacturers — using 
their exact schematics, golden units, and experienced ears — to give UAD plug-ins 
warmth and harmonics in all the right places, just like analog.
Nothing better represents the merging of our analog heritage and groundbreaking digital 
designs than the award-winning Apollo audio interface. Introduced in 2012, Apollo has 
become the new worldwide standard for professional music production, and has been 
used to record breakthrough albums by artists such as Kendrick Lamar, Coldplay, Dr. Dre, 
Brad Paisley, and many more.
With 165 employees and offices in Los Angeles, Colorado, and Amsterdam, Universal 
Audio is headquartered near Silicon Valley in Scotts Valley, California — where our 
classic analog gear is still hand-built, one unit at a time.
Software or hardware, every Universal Audio product is backed by a decades long legacy 
of innovation, superlative quality, and technical passion.
