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.

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.
But
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.

New x8

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. :)

GREAT UPGRADE

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

HEADROOM

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.

Just...wow!

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.

In Love.

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.

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 .

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!
