Elite-Class A/D and D/A Conversion
With thousands of chart-topping 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 interface’s 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 x8’s open, natural sound quality 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 x8 features new 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 musicians, engineers, producers, and sound designers, Apollo x8 features four 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
Of course, 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 x8 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 x8 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 SSL, Neve, Studer, Manley, Helios, API, Ampex, 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 x8 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

Plus, with its comprehensive 7.1 surround monitoring support, Apollo x8 is a boon for engineers and producers working on audio and music for video games, television, and the web. In addition, Apollo x8 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 x8 offers 18 x 24 simultaneous inputs/outputs (8 x 8 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.

Not really compatible
Just recently bought my apollo x8. And I already have more problems with it then I had with my Motu in the past 11 years.
In all honesty they should not sell it as compatible with Windows (10). Cause it just Isn’t.
Setting the card up was a horrible experience which required very difficult to make motherboard and software updates.
After I finally got it installed I noticed that it doesn’t connect to system audio (like media player, youtube etc.) the moment you start up the computer. For some reason I need to restart twice for the apollo to connect properly.
I noticed that the sounds of my synths in my daw hang more often. Which requires a rebooth of the apollo. That never happened with the motu. And frequent messages pop up in windows stating that it can not find the thunderbolt connection while it actually does. So all in all a lot of issues for windows users.
The thing I do like is the quick and easy Routing to my outboard gear and offcourse the uad plugins and the converters.
I should of bought the new prism sound and a UAD sattelite.
But for now I have to hope that Universal audio makes the software/ hardware better compatible for windows users.
Upgraded my Apollo duo silver
So much more DSP now. Definitely needed it. Also got a new Mac Mini. Everything worked as expected. Put it in +24 mode. I don't hear a difference but, the Silver Apollo sounded great so if there is a difference, it is too close to tell. I just love the extra DSP.
I am absolutely satisfied with the unit. I can only recommend it for those who want the best! Dynamics, clarity of sound and unbelievable detail. Works so well together with my ISA828. :)

Clean & Powerful TB3 interface!
Really low latency. Solid sound. The Unison feature is a winner.
Just 1 month of using my new apollo x8. the difference between this and the 8p is amazing! much more depth to my mixes. I feel like I have new ears :) Highly recommend the upgrade to the x series
Wow. That’s pretty much it. The headroom is so significant and better than my previous interface. Thought I’m only using this for line in(drums with api pres) I can push my pres much more than previously. Killer product.
I didn't want to do it
I resisted entering the UAD world for years and I'm glad I did. I needed to learn what was possible and impossible in a hybrid setup before before I got a piece of equipment that pretty much lets me do what I want. The x8 and really any sort of track-centric interface is for people who want to make decisions at the recording phase and the x8 offers some really attractive and stunning choices. The little bit of mixing I've done on it has been effortless and fun because the raw tracks sound so freaking good.
This is a pro instrument. My hardware preamps, compressors and eqs sound better than the Unisons but not by much and the Unisons are so much easier to use.
My 11-year old MOTU Ultralite is still working but I thought of upgrading to something with more I/Os. Not sure if I could hear the quality of the new AD/DA converters in the Apollo x8, but, 'wow'! There is really a difference between this new generation of converters versus the previous generations. Having some quality plugins to me is just a bonus— one could just buy the Apollo for the sound alone.
Moving from my Fireface 800 to my new Apollo X8 has been a huge step forward. I'm in love with the Unison plugins, with the converters and and with the warmth and depth of the sound. It's the feeling of being in another league.
If your reading this; just do it already.You won't be disappointed.
solid, comfort, sound
Necessary for a Professional Studio
Great selection of features paired with good hardware and awesome sound quality.
Works like a charm and sounds like bliss.
Apollo X8/Twin Quad upgrade from Motu Traveler w/ Mojavi
As an old timer recording in the late 80's and 90's on analog. It's amazing that the equipment I have in a bedroom is better than the studio I recorded then in at Castle Sound in Abilene. The only thing that can't be replaced are the Meltones and the late Michael Henry. This is an absolutely pristine interface with Logic Pro and the UA plugins.
Apollo X8 from silver 8 duo
The X8 has more weight a more solid sound with it switched to 24 volt . I'm using a dangerous D box and a big ben and there has been an improvement in sound quality with the X8 . I will know more once I track with the new conversion .
best audio interface
best audio interface. clearer mids better image , better converters the difference is huge than the previous versions! great job uad! thanks for the upgrade!
I finally made the plunge into the UA universe and it has made a world of difference in my output quality. I will never turn back.
Very much satisfied
Excellent D/A converter, UA finally nailed it! Upgrading from Apollo Twin MK2, it made my monitor speaker sound much much better.
6 DSP core is a big bonus.
Best Interface !
Easy to use , sounds great, you wont be dissapointed !
Skeptic to believer.
I originally had the Apollo 8 duo and upgraded to the Apollo 8x. When I first hooked it up the sound sounded too clean for my taste because the older Apollo I had added this padding and warmth to the sound that was so perfect its hard to describe. The shiny and bright sound of the new Apollo was hard to accept. I tried different settings of cue mixing, went back to re-mix other projects and everything. Then somehow after I had clicked +24db and something else I did, the warmth came back, but this time with depth, clarity and space! So now I am extremely pleased with the sound! But, the only other issue I had was, the processing power seems weaker than my Apollo duo for some reason, and it wasn't until I hooked both of them up together that the power returned. If I could open up all the cores I would rate this a 10!
