GET THE MOST POWERFUL DESKTOP APOLLO EVER

Universal Audio built Apollo x4 to expand on the gold-standard Apollo Twin, the interface that single-handedly revolutionized home and project studio recording. With its expanded I/O count, unprecedented dynamic range, and elite-class 24-bit/192 kHz audio conversion — now with enhanced monitoring — Apollo x4 puts the sound of the stars in reach for project studios and collaborators. With 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 textures used on the greatest recordings of our time.

MIX WITH AUTHENTIC ANALOG SOUNDS

Right out of the box, Apollo x4 gives you the tools used in the world's biggest recording studios. Along with included Teletronix LA-2A compressors, Pultec EQs, and amps from Marshall and Ampeg — you can tap into the entire library of over 200 UAD plug-ins and unlock proven hit-making sounds like Ocean Way Studios, Capitol Chambers, and many more. Now in its Gen 2 design, Apollo x4 features UA's highest-resolution D/A converters ever paired with Apollo Monitor Correction powered by Sonarworks. This means that when you playback your audio through monitors or headphones, you'll not only hear the most pristine representation of your recordings, there will be no surprises when you listen to your final mix or master.

FIND YOUR FLOW IN THE UAD CONSOLE APP

Just like an analog studio, where a console is the heart of the workflow, Apollo x4 has a powerful digital mixing engine where you control plug-in routing and monitoring. And with the latest features like Auto-Gain, Bass Management and Plug-In Scenes, it's easy to find a flow that fits your needs.

A HYBRID SYSTEM, MADE FOR YOUR MISSION

Combine Apollo x4's QUAD Core DSP with native processing from your host computer to produce large sessions with complex plug-in chains — a powerhouse hybrid workflow that outpaces any native-only recording setup. Build your studio by linking up to four Thunderbolt Apollo interfaces with up to 128 channels of premium I/O to your DAW, and control it all from your desktop using Apollo x4. So no matter how far your music takes you, an Apollo will always be in reach.
