Universal Audio Apollo Solo USB Audio Interface

Give your recordings genuine UA conversion and the benefit of classic mixing tools.
Featuring class-leading Universal Audio conversion, two Unison mic preamps, and a suite of built-in effects, Apollo Solo USB puts album-quality recording on your desktop. This 2 x 4 USB audio interface for Windows also includes a generous collection of UAD plug-ins to record vocals and instruments through, at near-zero latency.

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 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.

Built for Musicians, Electronic Producers and Songwriters
Apollo Solo USB's robust all-metal construction, best-in-class headphone amplifier, and superior audio conversion is perfect for musicians, songwriters, and electronic music producers who need UA quality in a compact package.
