Elite Audio Conversion with New HEXA Core Processing and Surround Sound.

Apollo x6 allows music producers and post-production studios to track, overdub, and mix with elite-class A/D and D/A conversion, HEXA Core UAD plug-in processing, Dual-Crystal clocking, and 5.1 surround sound monitoring — all in a sleek rackmount Thunderbolt 3 audio interface for Mac or Windows.

Built upon UA’s 60-year heritage of audio craftsmanship, this 16 x 22 interface easily outperforms everything in its class with two Unison-enabled mic preamps, all-new HEXA Core processing — yielding 50% more DSP for running UAD Powered Plug-Ins in real time — plus it includes LUNA Recording System, giving you a fully-integrated music production application.

Record with elite-class A/D and D/A conversion — nearing the widest dynamic range and lowest noise available, at any price

Mix with powerful HEXA Core processing, featuring 6 UAD DSP chips for running more UAD Powered Plug-Ins in real time

Track with near-zero latency through Unison™ preamp emulations from Neve,® API,® Manley,® Helios,® Fender,® and more

Includes LUNA Recording System — a fully-integrated and inspiring music production application

Elite-Class A/D and D/A Conversion

With thousands of hit songs and hundreds of Grammy-winning albums under their belt, Apollo interfaces are no strangers to tracking stellar-sounding records. To improve on the previous generation Apollo interfaces’ class-leading audio conversion, UA engineers obsessively auditioned the latest A/D and D/A converters — ultimately pairing elite-class 24-bit/192 kHz converters with all-new analog circuitry for an ultra-pristine signal path.

The Apollo X series also introduces new Dual-Crystal clocking — featuring dedicated crystals for 44.1/88.2/176.4k and 48/96/192k sample rates — resulting in stunningly low jitter, measured at less than 10 picoseconds. This translates into pure, artifact-free recordings and solid stereo imaging you can trust.

With 129 dB dynamic range and -119 dB THD+N, Apollo x6’s open, natural sound rivals any dedicated high-end converter on the market — regardless of price — and is the perfect starting point for applying UAD processing.

Realtime UAD HEXA Core Processing

Apollo x6 features HEXA Core processing, with six DSP chips and 50% more UAD plug-in processing power than previous Apollos. This lets you run more UAD plug-ins, whether you’re tracking in real time with channel strips from Neve, Manley, or API, or running high UAD plug-in counts when mixing in your DAW.

From the tube warmth of Pultec EQs on guitars to the musical tube limiting of the LA-2A on vocals, or the pump of a genuine 1176 or Fairchild 670 tube compressor on drums, your recordings will take a giant leap forward with a rich, three-dimensional analog sound that UAD plug‑ins provide.

Unison Technology: The Genuine Sound of Neve, API & Manley Preamps

Perfect for electronic musicians and post production professionals who don’t require tons of mic inputs, Apollo x6 features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve, API, Manley, Helios, SSL, and Universal Audio. A Universal Audio exclusive, Unison technology nails the tone of these sought-after tube and solid state mic pres — including their input impedance, gain stage “sweet spots,” and the component-level circuit behaviors of the original hardware.

The secret to Unison is its hardware-software integration between Apollo’s mic preamps and its onboard HEXA Core DSP Acceleration. Simply place a Unison preamp plug-in on your mic input in Apollo Console software, and it physically reconfigures the Apollo interface's impedance — so you can tap into the classic sounds of the world’s most recorded mic preamps.

The quality of the plugins and sound are stellar ! Luna is a producers paradise .

Simply love it

This is a brand new step in music production, unison preamp are absolutely great, and i'm really blown out by the analagic emulation of their native plugins, but to be honest, every single plug in sounds better with UAD interfaces

Serious upgrade!



If you’re looking for a new interface, this is it! Very good sounding converters in combination with the unison plugins and low latency a very good product.

Best interface on the market

After working with an apollo twin for several years, I decided to upgrade for more dsp power and some extra inputs for analog devices. The X6 is a dream and I was very pleased to find that my apollo twin seamlessly works with my new X6. I now use it as a volume control remote for the X6, as well as extra preamps and dsp. Amazing how these systems work together, absolutely brilliant. Worldclass preamps and conversion, this is simply the way to go whether you're working in a big studio or a small home setup.

Great interface

ive been wanting one of theses for a few years now, finally brought one a few weeks back, wow what a bit of gear it is.. sound quality is amazing.. im using it to record dj mixes into and also for music production in logic x.. the dsp it great and allows me use what plugins I need without putting to much load on my Mac.. very happy! Props to UAD

Best Interface for a small home studio

Seriously, Just get this interface. If you don't need that much inputs, and need that DSP power, This is the interface to get. I don't regret it at all

Fantastic build and sound quality. Very pleased with the X6. Highly recommended.

Sounds much better than the black much sharper and tighter. Knobs are a bit slack but it should hold for a while.
Great hardware and serious conversion upgrade.

Beast of a Device - Sound Quality and DSP Power

This device is perfect cross choice between the desktop and rack based device in terms of power and performance. This gives you the same DSP power as the high end devices. The sound quality I feel is better than the Twin X - it has a better sound when outputing from the speakers. I love using this device and got it working along side the Twin X

2 word s “the best”

Simply the best audio interface for out there today, clear and transparent when you want, and harmonics she. You need, unison preamps make this device the best out there for
Home and professional studios. Good job UA...

D. Bailey

November 22, 2020

Great Improvement over my old interface

I really like the way this X6 works. It's also VERY quiet. If something is noisy, it's the sound source, not the interface. I’m looking forward to using it. Only thing I don't like is the external power supply and high plug in prices.

K. Køningsberg

November 21, 2020

Sometimes..

...you buy a piece of gear that simply elevates your studio (bedroom or pro) to the next level. This is one of those pieces of gear. The sound of it is crisp and clean, the hexa core dsp is a godsend and it has more than enough IO for the modern producer.

F. Grüber

November 20, 2020

A BIG STEP FORWARD

Definitely a big step forward for me and my work. I've been using lots of USB interfaces for mixing, even for recording but now using this monster I feel my studio get bigger and more pro.

In every situation I have a great feeling to work with a professional device. No latency at at recording and sounds great on mixing sessions. I like the guitar plugins in combination with unison.
