Get Our Most Powerful Desktop Apollo Ever

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 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.

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.

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.
