History of the Model 2192 
In 2000, legendary audio engineer Bill Putnam Sr. 
was awarded a Technical Grammy for his multiple 
contributions to the recording industry. Highly 
regarded as a recording engineer, studio 
designer/operator and inventor, Putnam was 
considered a favorite of musical icons Frank 
Sinatra, Nat King Cole, Ray Charles, Duke 
Ellington, Ella Fitzgerald and many, many more. 
The studios he designed and operated in the 1950s 
and 1960s were known for their sound and his 
innovations were a reflection of his desire to 
continually push the envelope. 
In addition, the companies that Putnam started—Universal Audio, Studio Electronics, and UREI—
built products that are still in regular use decades after their development. In 1999, his sons Bill Jr. 
and James Putnam re-launched Universal Audio and merged with Kind of Loud technologies—a 
leading audio software company—with two goals in mind: to reproduce classic analog recording 
equipment designed by their father and his colleagues, and to design new recording tools in the spirit 
of vintage analog technology. 
One of the most exciting of these new recording tools is the 2192 Master Digital Audio Interface, the 
first product to combine UA’s long history of creating high-quality, analog gear with its advanced 
digital technology. Providing two channels of analog to digital conversion, two channels of digital to 
analog conversion, digital format conversion, and a master word clock generator/distribution amp for 
an entire digital hardware array, the 2192 is the perfect front end for Pro Tools and other digital audio 
workstations. 
While advances in digital technology have made tracking, mixing and recording a much easier 
experience, the sound of digital had yet to aspire to the sound of the analog recording until very 
recently. The 2192 was built to deliver the very best audio fidelity possible. To that end, only the 
highest-quality analog components are used, and all the latest advents in digital technology are 
supported, such as high sample rates (up to 192KHz) and full 24-bit conversion. 
Today Universal Audio is bridging the worlds of vintage analog and DSP technology in a creative 
atmosphere where musicians, audio engineers, analog designers and DSP engineers intermingle and 
exchange ideas. Every project taken on by the UA team is driven by its historical roots and a desire to 
wed classic analog technology with the demands of the modern digital studio. The 2192 truly sounds 
analog, but not necessarily like tape; and yet it somehow retains the neutrality necessary for a digital 
converter. But it does this without the wow and flutter, phase, crosstalk, and other baggage you’d 
expect with tape. In the words of famed producer Eliot Mazer, “…anyone hearing a 24-bit/192kHz 
recording can’t believe how great it sounds. When I get music into Pro Tools|HD at 192kHz with 
external converters like the Universal Audio 2192, it sounds analog. Analog to me is not hearing the 
system, it’s music that sounds natural. I’m no longer distracted by the limitations and distortions of 
low sampling and bit rates.”
