Universal Audio Apollo X4 Gen 2 12×18 Thunderbolt Audio Interface

Record hits with the world’s most powerful desktop audio interface.
Produce larger sessions with the most powerful desktop Apollo. Featuring highest-resolution audio conversion, four Unison™ mic preamps, and realtime UAD processing — letting you record through plug-ins from Neve, API, Manley, Auto-Tune, and hundreds more — Apollo x4 levels up your studio with legendary UA sound, built to inspire your next collaboration.

Get The Most Powerful Desktop Apollo Ever
The Apollo x4 was built to expand on the gold-standard Apollo Twin, the audio interface that single-handedly revolutionized home studio recording. With expanded I/O, elite-class 24-bit/192 kHz audio conversion, and the widest dynamic range to date, Apollo x4 puts the sound of the stars in reach for your next collaboration.

Record Through Iconic Preamps
With four Unison™ preamps and dual front panel Hi‑Z instrument inputs, Apollo x4 lets you track through emulations of classic gear from Neve, Manley, API, Fender, and dozens more, giving you the rich analog textures used on the greatest recordings of our time.

Hear the Details Like Never Before
Now in its Gen 2 design, Apollo x4 features our highest-resolution D/A converters ever. This enhanced monitoring — when paired with features like Apollo Monitor Correction by Sonarworks* — means you’ll hear the most accurate representation of your recordings when mixing through monitors or headphones.

Mix with Authentic Analog Sounds
Out of the box, Apollo x4 gives you the tools used in the world’s biggest recording studios. Along with included LA-2A compressors, Pultec EQs, and amps from Marshall and Ampeg — you can tap into the entire library of over 200 UAD plug-ins to unlock proven hit-making sounds. Apollo x4 comes with two editions – Essentials+ featuring the UAD Essentials+ Plugin Suite, and Studio+ featuring the UAD Studio+ Plugin Suite.

Find Your Perfect Workflow
Just like many pro studios, where an analog console is the heart of the workflow, Apollo x4 has a powerful 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 for Your Mission
Combine Apollo x4’s DSP processing with native processing from your computer to produce large sessions with complex plug-in chains — a powerhouse hybrid workflow that outpaces any native-only recording setup.

Expand Your Studio as You Grow
