This compact 2x4 interface starts with esteemed Apollo A/D and D/A conversion to sonically outperform anything in its class. And with its Unison technology and built-in UAD‑2 processing, you can record through classic studio tools including the UA 610‑B Tube Preamp & EQ, LA‑2A and 1176 compressors, and more — with 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 preamps. These include the bundled UA 610‑B Tube Preamp, plus authentic mic preamp emulations from Neve® and API,® plus guitar amp emulations from Fender® and Marshall® — complete with their signature impedance, gain stage “sweet spots,” and component‑level circuit behaviors.*

The secret to Unison is its hardware‑software integration between Apollo Solo USB's mic preamps and its onboard UAD-2 processing. Simply place a Unison preamp plug-in on your mic input in Apollo's Console software, and it physically reconfigures Apollo’s impedance and gain staging — giving you the classic tube and transformer sounds of the world’s most recorded mic preamps and guitar amps.

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

Derived from Universal Audio’s award-winning Apollo interfaces, Apollo Solo opens up a range of classic analog color via its Realtime UAD Processing. Featuring an onboard UAD-2 SOLO Core processor, Apollo Solo 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.

A Full Suite of Classic Studio Processing Onboard

Right out of the box, Apollo Solo USB provides a suite of incredible analog emulation plug‑ins including the world’s only authentic Teletronix LA‑2A and 1176LN compressors, Pultec EQs, and much more. From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA‑2A on vocals, your recordings will take a giant leap forward in rich, sonically complex analog sound.
