Get a closer look at the Apollo Solo in this one-minute overview from UA:


Unison Technology for Stunning Mic and Guitar Preamp Emulations

Apollo Solo USB's Unison technology gives you the tone, touch and "feel" of the world's most sought-after tube and transformer-based mic preamps and guitar amps. It includes the UA 610-B Tube Preamp, Marshall Plexi Classic Amplifier, and Ampeg SVT-VR Classic Bass Amp plug-ins -- and can be expanded with exclusive titles from Neve, Avalon, SSL, Fender, and more. The secret is a unique hardware-software integration, which adjusts the impedance of Apollo's instrument and mic preamps to match the emulated hardware -- for authentic analog sound unmatched by other recording interfaces.

Realtime UAD Plug-In Processing for Recording with Near-Zero Latency

Derived from Universal Audio's award-winning Apollo interfaces, Apollo Solo USB opens up a range of classic analog color via its Realtime UAD Processing. Featuring an onboard UAD-2 SOLO Core processor, Apollo Solo USB lets you monitor and record through the full read more library of UAD Powered Plug-Ins -- at near-zero latency, regardless of your audio software buffer setting. It's like having a virtual analog studio that fits in a laptop bag.

The UAD library features more than 100 titles and offers everything from classic Moog filters to Ampex tape to Lexicon reverbs -- with more being added every few months. These are the exact same UAD plug-ins used on hit records by Billie Eilish, Kendrick Lamar, Dr. Dre, Foo Fighters, and many more.
