Apollo Twin Hardware Manual Welcomeii
A Letter from Bill Putnam Jr.
Thank you for deciding to make the Apollo Twin High-Resolution Interface part of your 
music making experience. We know that any new piece of gear requires an investment 
of time and money — and our goal is to make your investment pay off. The fact that we 
get to play a part in your creative process is what makes our efforts meaningful, and we 
thank you for this.
In many ways, Apollo, Apollo 16, and Apollo Twin represent the best examples of what 
Universal Audio has stood for over its long history; from UA’s original founding in the 
1950s by my father, through our current vision of delivering the best of both analog and 
digital audio technologies. 
Starting with its high-quality analog I/O, Apollo Twin’s superior sonic performance serves 
as its foundation. This is just the beginning however, as Apollo Twin is the only desktop 
audio interface that allows you to run UAD plug-ins in real time. Want to monitor yourself 
through a Neve® console channel strip while tracking bass through a classic Fairchild or 
LA-2A compressor? Or how about tracking vocals through a Studer® tape machine with 
some added Lexicon® reverb?* With our growing library of more than 90 UAD plug-ins, 
the choices are limitless. 
At UA, we are dedicated to the idea that this powerful technology should ultimately serve 
the creative process — not be a barrier. These are the very ideals my father embodied as 
he invented audio equipment to solve problems in the studio. So as you begin to incor-
porate Apollo Twin into your creative process, we hope that the excitement and pride 
that we’ve built into it comes through. We believe Apollo Twin will earn its way into your 
creative workflow by providing stunning fidelity, great ease-of-use, and rock-solid reliabil-
ity for years to come. 
As always, please feel free to reach out to us via our website www.uaudio.com, and via 
our social media channels. We look forward to hearing from you, and thank you once 
again for choosing Universal Audio.
Sincerely,
Bill Putnam Jr.
