Universal Audio APOLLO X4 HE

Produce bigger pro sessions from your desktop, in realtime.
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, SSL, and more — with near‑zero latency — giving you a fully-stocked analog studio, right on your desktop.

Hear Every Detail in your Recordings
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.

Record Synths and Vocals through Iconic Preamps
With its four Unison™ preamps and dual front panel Hi‑Z instrument inputs, Apollo x4 lets you track in realtime through preamp and channel strip plug-ins from Neve, Manley, API, and dozens more, giving you the same rich analog texture as the hardware used on decades of iconic music.*

Out of the box, Apollo x4's included plug-ins give you album-ready tones in realtime with professional tools like the UA 610-B Tube Preamp & EQ, Teletronix LA‑2A tube compressor, amps from Marshall and Ampeg, and more. Plus, Apollo x4 lets you tap into the entire UAD plug-in library, giving you the proven hit-making sounds of Ocean Way Studios, Capitol Chambers, and hundreds more.
