High-quality recording in a desktop-friendly interface.

Shape your recordings into records with genuine UA conversion, classic mixing tools and LUNA Recording System with the Apollo Solo Thunderbolt 3 audio interface. Featuring class-leading Universal Audio conversion, two Unison mic preamps, and a suite of built-in effects, Apollo Solo puts album-quality recording on your desktop. This 2 x 4 Thunderbolt 3 bus-powered audio interface for Mac and Windows includes a generous collection of UAD plug-ins to record vocals and instruments through, at near-zero latency — plus it offers full integration with Universal Audio's groundbreaking new LUNA Recording System.

Unison Technology for Stunning Mic and Guitar Preamp Emulations
Apollo Solo'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 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.*

LUNA Recording System with Accelerated Realtime Monitoring

Apollo Solo works with all major DAWs, including Logic Pro, Ableton Live, Pro Tools and more. But it becomes a fully integrated recording system with LUNA, a powerful free recording application for Mac from Universal Audio. Bolstered by Accelerated Realtime Monitoring, LUNA lets you track and mix in an intuitive single-window workflow with unlimited track counts, full AU support and access to a suite of exclusive LUNA Instruments and Extensions.

From integrated Studer multitrack tape and built-in Neve Summing, to instruments from Moog and more, LUNA transforms Apollo Solo into an incredibly inspiring music creation platform.

Built for Musicians, Electronic Producers and Songwriters
Apollo Solo's portable Thunderbolt 3 bus-powered design, 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.
