The centerpiece of your next music production.
UA’s next generation of Apollo x6 interfaces is here, giving producers and project studios highest-resolution audio conversion, two Unison™ mic preamps, and HEXA Core DSP processing for writing and producing with world-class UAD plug-ins from Auto-Tune, Neve, Manley, Avalon, SSL, and hundreds more.

Trusted by top producers and engineers around the globe who need elite-class Apollo X sound and DSP power, but without the added hardware channels of larger models, Apollo x6 levels up your production space with timeless sound and legendary UA craftsmanship.

The New Centerpiece of Your Rack
Universal Audio built Apollo x6 for producers who need the highest-quality audio, without the additional analog preamps found in larger rackmount models. With unprecedented dynamic range and elite-class 24-bit / 192 kHz audio conversion — now with enhanced D/A monitoring — Apollo x6 puts the sound of the stars right in your rack.

All the Inputs You Need
With two Unison™ preamps and front panel Hi‑Z instrument inputs, Apollo x6 lets you track in realtime with the sound of classic gear from Neve, Manley, API, Fender, Marshall, and dozens more. And with an additional six line inputs, it’s easy to connect your hardware synths, keyboards, and other outboard gear.

Mix with Vintage & Modern Sounds
Right out of the box, Apollo x6 gives you the tools you need to create awe-inspiring mixes. Along with included synthesizers and tape echos, Teletronix LA-2A compressors, and Pultec EQs — you can tap into the entire library of over 200 UAD plug-ins to unlock proven hit-making tools that will push your productions to the next level.

Hear the Details Like Never Before
Now in its Gen 2 design, Apollo x6 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 x6 has a powerful digital mixing engine where you control plug-in routing and monitoring. And with the latest features like Auto-Gain, Bass Management, 5.1 Surround Sound and Plug-In Scenes, it’s easy to find a flow that fits your needs.

A Hybrid System, Made for Your Mission
Combine Apollo x6’s HEXA 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.

Expand Your Studio as You Grow
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 Twin or x4. So no matter how far your music takes you, an Apollo will always be in reach.
