Apollo x4 gives engineers and producers recording larger projects the same professional analog tones heard on your favorite records with four onboard Unison^™ mic preamps. With elite‑class conversion and QUAD Core UAD plug-in processing, Apollo x4 lets you record through preamps from Neve, API, Manley, Antares, SSL, and more — with near‑zero latency — giving you a fully-stocked analog studio, right on your desktop.

Apollo x4 improves upon the original Apollo Twin’s gold‑standard audio quality with completely redesigned A/D and D/A conversion — giving you increased dynamic range and ultra‑low THD. This elite‑class conversion gives you a spacious, organic sound that easily rivals dedicated high‑end converters.

The Apollo x4 is perfect for adding up to four channels of Auto Tune to your playback rig in a compact interface that fits perfectly in our ZERO-G racks. Don't need as much I/O? The Apollo Solo and Apollo Twin X include more streamlined I/O and features with Universal Audio's legendary audio quality.
