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 new world-beating 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 PC.

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, providing authentic emulations of preamps from Neve, API, Manley, SSL, and more, plus all-new HEXA Core processing — yielding 50% more DSP for running UAD Powered Plug-Ins in real time.

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

Integrate with high-end commercial systems, via 5.1 surround sound monitoring and selectable +24 dBu headroom

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 Future is here!!!

We have to admit that we go forward, into the future, where all the things they have to be simple and practical and Universal Audio they know very well how to do it!!!
Apollo, an amazing line, simple and intuitive, warm and very good in micro-details.

Love it! Seems pretty solid overall. The conversion is really good and sounds amazing. I also love the headphone amps. Haven't tried unison yet. Every plugin I've bought impresses me very much.

The Apollo X6..

The Apollo X6 has the most complete AD/DA converter I have ever used in the audio interface. It's literally the best.

Winner

We just installed two Apollo x6 at Palma Music Studios on Mallorca. Since we have a lot of clients that work with UA hardware in their own studios, it´s great to be able to offer them to just connect the cable and be up and running with their own system settings in no time. And the AD/DA is a big step up from previous interfaces. /Thanks!

I like it!

Not a bad decision to jump on UAD wagons. Only the midi I / O is missing from the complete package.

Everything I love about this interface and the few things I don't;

When I plugged my new Apollo X6 into my 2013 MacBook Pro, my expectations
where somewhat muted.
Thinking that computers age much the same as dog years, I was expecting
(potentially) stability issues, error messages, etc.
I was happily proven wrong, as the Apollo has been rock solid (on fairly large projects.)
I replicated then same project and opened it up on an even older Mac mini with thunderbolt 1.
"Here we go" I thought.
Now the shit's really going to hit the fan.
Nope..everything ran perfectly.
Then one final test;
I plugged the Apollo into a Lacie thunderbolt hard drive, then the Mac mini.
Again expecting something to go wrong, the only message I got was to increase
the input delay compensation.
After doing so, everything again ran perfectly.

So why aren't I immediately mentioning the converters, then
pre's, unison, etc etc?
None of that matters without a stable platform for this to run.
Happily UA supplies exactly that.
Oh..the pre's, and converters are fantastic. ;)

My few negatives?
1. No thunderbolt cable/with adaptor.
IN 2019 with an interface of this quality not supplying the cables
and needed adaptors is inexcusable.
I'm not concerned about the additional cost, but its like buying a Porsche without
getting the keys.
Also please ..no talk about choosing your own cable or something..
that's utter nonsense.
2. The plugins are MASSIVELY overpriced.
Sorry, but after performing a few null tests between the DSP powered
ones and the native ones, (when, to be fair their are equivalents)
there's no difference.
I understand that coding for specific hardware is potentially more time
consuming, but some of the price points are really outlandish.

I purchased this interface primarily for the A/D D/A's and improved clocking
Happily The X6 doesn't disappoint.

The Best audio interface on the market!

I have been using Universal Audio products for about 5 years. From the Apollo Twin Usb series, then I switched to Apollo 8 and now I have Apollo x6. Reproduces stunning sound, microphone preamps are excellent, Unison technology is very pleased with its quality! I advise everyone to buy this equipment!

M. Heffernan

May 14, 2019

Very Nice.

This was my first buy into the UA products family, so far I’m very happy! The speed at which I can get ideas down and recorded, along with sounds I am happy with, is really cool! For me recording with a little bit of EQ and decent compression on the way in, with the Fairchild or la2a is really inspiring! It drives my enthusiasm! My monitors and my headphones sound better, so in turn I guess I will be able to make better decisions while tracking and then mixing! The quality of the pre amps and the AD/DA seems to be excellent! The Di sounds great with my bass guitar along with the UA 610-B Tube Preamp using the unison technology! Very cool tones! The presents on the plugins are really nice to quickly click through a few tonal options and then tweak to taste!
I also contacted Ua costumer service when I first received the X6, they replied quickly and were very helpful! All in all a good experience using the X6 so far.

Just what the Dr ordered

Should have brought from UA years ago.
Have wasted money on cheeper devices over the years. The plugins and super low latency make everything I do easier and faster.
The quality of the pre amps and the AD/DA are clear and musically pleasing from di guitars and bass with active and passive pickups.
Very happy with my decision.

Great unit

Replaced a Twin MKII with the X6. Noticeable upgrade. all round. Wouldn't say it's night and day on the DA, but noticeable.

Haven't tried the pre's yet, so looking forward to that. But even the headphone amp is better (goes much louder, with better clarity) and it's great to have 2 again.

An amazing upgrade that's miles ahead.

I upgraded my Silverface Apollo to the x6 recently, and it's been one of the best things i've done in my studio. The new AKM chips in the converters (same chips as Merging Technologies Horus / Hapi) really put it miles above my old Mytek converter. The Mytek mastering converter has now been sold. The stereo field is so much more detailed with the x6. Anyone with an older Apollo would be wise to also make the upgrade to the X series. Adding that with all the i/o plus the ability to use some of the best plugins on the planet really makes this a no brainer. Thank you UAD!

replaced my hd system

Greetings after running a gigantic HD system for the past 6 years I decided time to replace the Digidesign gear with UAD . Simple straight forward to use and sounds amazing . I bought an X8 and liked it so much I added an X6 and now have full 24 channels of Adat as well as the onboard Pre- amps . happy guy.
