Universal Audio APLS Apollo Solo Thunderbolt 3 Interface

The Universal Audio Apollo Solo is a desktop 2x4 Thunderbolt 3 audio interface that brings UA's renowned conversion quality and real-time UAD processing into a compact, bus-powered form factor. At its core are two Unison mic preamps that go beyond simple gain staging — they physically adjust the input impedance of the Apollo's preamp circuitry to faithfully emulate classic hardware from Neve, API, Avalon, Manley, and others. This means the tone-shaping happens at the analog input stage, not just in software, delivering a more authentic sound when tracking vocals, instruments, or guitars through amp emulations from Marshall, Fender, and more.

The onboard UAD-2 SOLO processor handles real-time plug-in effects with near-zero latency, allowing musicians to monitor through studio-quality compressors, EQs, and reverbs while recording, regardless of the DAW's software buffer setting. The included Realtime Analog Classics bundle provides a solid starting collection of mixing tools. For Mac users, UA's free LUNA Recording System offers deep integration with Apollo hardware, including Accelerated Realtime Monitoring and tape emulation. With class-leading 24-bit/192kHz conversion and a single Thunderbolt 3 cable for both power and data, the Apollo Solo delivers professional studio quality in a portable package suited to home studios, mobile recording, and content creation.
