Apollo x8
-
Elite Audio Conversion with Four Unison Mic Preamps, HEXA Core Processing, and Surround Sound.
Apollo x8 allows music producers, project, 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 7.1 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 18 x 24 interface distinguishes itself with four 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 7.1 surround sound monitoring and selectable +24 dBu headroom
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 OnboardOf 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.
See Included Plug-Ins | Watch the live tracking videoAccess 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
The Apollo x8 features built-in front-panel monitoring functions including a Talkback mic, Alt Speakers, and assignable Dim or Mono control. 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.

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 .
I. Papagiannidis
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!
R. Lynn
The Best!
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.
W. Oh
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.
D. Ironside
Best Interface !
Easy to use , sounds great, you wont be dissapointed !
k. mcintosh
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!

Worth every penny
Chose to upgrade from a Apollo 8 and a Twin to this beast. I run it together with a Blackface 8P for more preamps, and it is the heart of our small studio.
I was surpriced that I actually could hear a difference in sound. It's not a groundbreaking difference from the Apollo 8 (gen 2), but audible none the less.
Love it!K. Volpe
Wonderful Interface
I had an Apollo Quad for the last few years, which I loved. The new x8 is at an even higher level..I know it sounds like a cliche..but it really is more open on the top end and the sound field appears wider. Really happy about having an increase in DSP power. I also love some of the new function features. I can't say enough good things about the x8.
R. Peters
Very statisfied !
Love the low latency, ease of use and streamlined workflow in any situation. Be it mixing, recording or creating.
J. Anaka
replaced my hd system
great clean sounding interface , console app takes a bit to get your head around. The unit is quick, transparent and smooth . Selling off my older HD system now. I am going to buy another soon .
J. Reinholdt
A great update
I used an Apollo 8 / Satellite Quad combination before and was sometimes frustrated that I could not use the DSP power of both units combined. Now, that has been fixed with Apollo 8x which has all DSP power I need in one spot.
K. Kiive
New Apollo X8!
I’m coming from an RME UFX and wanted to upgrade mostly to thunderbolt from FW because i felt like FW was disappearing... put the Apollo X8 in my system and just cranked AC/DC Thunderstruck! The DA was not just a subtle experience. It sounded much more 3D. Made my Dynaudio 5A’s sound like very expensive monitors.

Apollo x: Present and Future of the recording and the musical production.
I am very happy with the extreme audio quality obtained with my new Apollo x8.
In the Studio we also have an A/D & D/A converter (Symphony I/O from Apogee) and in the tests we have done comparing the conversion in real time with 24Bits / 48Khz files the result is surprisingly similar.
Only for this update in the converters, I consider it a winning horse.
It is also worth mentioning the four Mic Preamps (with the advantage of the Unison™ preamp emulations), the fantastic quality of their emulations in their plugins and how stable is the software (Application) Console + UAD Meter & Control Panel.
Good work Universal Audio !!!
