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.

The Gold Standard, on Your Desktop
We built Apollo x4 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.

Track through emulations of classic gear from Neve, Manley, API, and dozens more with Unisonâ„¢ preamp technology, 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, 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.

Find Your Perfect Workflow
Just like many pro studios, where an analog console is the heart of the workflow, Apollo Twin X 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 QUAD Core 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.

Build out your dream studio by linking up to four Thunderbolt Apollo interfaces for up to 128 channels of premium I/O, 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.
