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.
Watch the Unison Shoot Out
What happens when you put Apollo’s Unison preamp models up against their vintage analog counterparts? Producer Jacquire King (Tom Waits, Kings of Leon) finds out at the legendary Blackbird Studios in Nashville.
A Full Suite of Classic
Analog Processing Onboard
A hallmark feature of Apollo is its Realtime UAD Processing, letting you run the full library of UAD plug-ins with near-zero latency. Apollo x6 includes the Realtime Analog Classics Plus plug-in bundle, so you can record and mix with the world’s only authentic Teletronix LA-2A, 1176LN, and Fairchild compressors, the Unison-enabled UA 610-B Tube Preamp & EQ, and iconic guitar and bass amps from Marshall and Ampeg.

Access the World of UAD Powered Plug-Ins
Going beyond the included Realtime Analog Classics Plus plug-ins, Apollo x6 lets you tap into the full UAD Powered Plug-In library of legendary vintage EQs, compressors, reverbs, tape machines, channel strips, and more — at near-zero latency, regardless of your audio software’s buffer size and without taxing your computer’s CPU.
With exclusive emulations from Neve, Studer, Manley, Helios, API, Ampex, SSL, Lexicon, Fender, and more,† it’s like having a studio full of iconic analog gear, in a single rack space. And unlike competing interfaces, these award-winning DSP-powered plug-ins are also available in your DAW for mixing.
†Apollo x6 includes the “Realtime Analog Classics Plus” UAD plug-in bundle. Other UAD plug-ins sold separately at www.uaudio.com.
Surround Sound, Talkback, and More
The Apollo x6 features built-in front-panel monitoring functions including a Talkback mic, Alt Speakers, and assignable Dim or Mono control. Plus, with its comprehensive 5.1 surround monitoring support, Apollo x6 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x6 offers selectable +24 dBu operation for out-of-the-box compatibility with professional mixing consoles and other high-end pro audio equipment.
Build an Expanded Studio System Over Thunderbolt
Apollo x6 offers 16 x 22 simultaneous inputs/outputs (6 x 6 analog I/O) and two built-in Thunderbolt 3 ports. This allows users of any Thunderbolt-equipped Apollo Twin or Apollo rackmount audio interfaces to easily combine up to four Apollos and six total UAD-2 devices — adding fast, high-bandwidth I/O and DSP as your studio grows.
Apollo X Tech Talk
Universal Audio’s Senior Product Manager, Gannon Kashiwa dives deep into the key features, specs, and development behind the latest generation of Apollo audio interfaces.
“I love my new Apollo x8p! I can mix without worrying about the amount of plug-ins I use, and the new converters reveal the most subtle details when I record. One of the best upgrades that I’ve added in a long time.”
– Derek ‘MixedByAli’ Ali (Kendrick Lamar, SZA, Childish Gambino)
“WOW! I thought the second-generation Apollos were great, but these new Apollo X models sound so good, they will redefine the way records are made.”
– Jacquire King (James Bay, Kings of Leon, Tom Waits)
“This is the best-sounding Universal Audio D/A ever. By far. It has an extra octave of clear bottom, but it's not hyped. It's just very solid and full. It's like there’s no converter generated signature at all. It’s completely open and natural.”
– Fab Dupont (David Crosby, Shakira, Santigold)
Apollo: The Choice of New-School Professionals
Apollo is the confirmed choice of hit-making professionals, used to record landmark albums by Kendrick Lamar (DAMN.), Chris Stapleton (From A Room: Volume 1), Arcade Fire (Everything Now), Post Malone (Beerbongs & Bentleys), and many more. The Apollo range of interfaces has earned numerous industry awards from Sound on Sound, Future Music, and Electronic Musician — as well as the prestigious 2016 TEC Award for computer audio hardware.

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!
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.
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.
Apollo X 6
An Amazing piece of gear & simply designed for straight forward set up & use!
Ravi par ma X6, excellents convertisseurs, je l'ai acheté surtout pour le live pour avoir avec moi les excellents plugs 480L dans la console UAD,
c'est pratique, fiable,
et ça sonne
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.
Sounds great and does exactly what I expect it to do. However I do wish it had at least 2 more inputs
Great piece of gear awesome sound love the processing power
What I expected plus some.
I once thought only the Apogee Rosetta and Big Ben (90's) were the ultimate combo but now..No need for separate conversion or clocks. First lets get to the bottom line. You get to actually hear your ideas come together quicker so that you dont burn your ears out. Second, I dont know who thought this would be an upgrade of the Black face apollo but its not... Its and all new beast that killed its ancestor. Literally !! This will actually make you stop buying extra gear that you probably don't need but want. I'm a gearslut for life but damn! Its actually more efficient than the previous versions. More plugins and I mean huge plug ins can run at the same time... If you run out of DSP, you need to rethink your tracking/recording/Talent department cause you really shouldnt run out unless your doing a Skywalker/Star wars film or something... This piece will leave you with no more excuses on why your song sucks or didnt get radio play, it only leaves the talent to decide at this level of gear. Get over the price people. It will literally actually save you money so that you don't need to buy more crap after a remorseful purchase on that other so called interface and outboard gear. Im still all about outboard but you need to know when enough is enough and learn how to use both digital and analogue properly to your advantage. No more A versus D. Put them together and make music !!
Great Sound! Needed a new interface and was waiting for something next level for my workflow that didn’t require tons of pres for my hybrid mixing setup. Also allows recording vocals with the unison technology. Finally some one released a product for those us of who need serious sound and DSP, although we moved our setups to smaller rooms or at home
I owned an Apollo USB Twin before. Was already happy with it. But i did miss some extra I/O. After switching from Pc to Mac and after watching reviews i finally decided to also make the step to the new X Series. My expectations and more for sound quality(got blown out of my seat), Unison, I/O, pre amps and just the intuitive handling. Universal Audio: There is no other.
So far my best sound card. Finally, I hear the differences between the piano sounds in my Nord.
Just when I thought it couldnt get any better...
I own the first series of Apollo units and they are truly amazing...I got the x6 to work on studio projects at home but it's so amazing Im gonna have to replace all my old units with the X's
Quality of this is AMAZING!
Every time I record something or use UAD plugins I get that WOW effect!
I’ve had three apollo’s now. This tops them all!! The converters are better and they give you 6 dsp chips compared to the two in my Apollo 8 Duo. Hands down the best audio interface out there. Well worth the money.
Been waiting for this unit a longtime. The build is solid, software of course is great. And it sounds amazing
