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 elite-class 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 Windows.

Built upon UA’s 60-year heritage of audio craftsmanship, this 18 x 24 interface distinguishes itself with four Unison™-enabled mic preamps, all-new HEXA Core processing — yielding 50% more DSP for running UAD Powered Plug-Ins in real time — plus it includes LUNA Recording System, giving you a fully-integrated music production application.

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

Includes LUNA Recording System — a fully-integrated and inspiring music production application

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.

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.

sloppy customer service

I bought a Apollo 8 thunderbolt a few years ago. The thunderbolt port broke (not sure how and why). I have been trying to get it repaired for more than a year now. Covid has made that an impossible process, I understand that there are delays but at this point I don't see how the delay, this kind of delay, is acceptable. I had to buy another interface and keep getting negative responses from customer service, Never going to buy anything UA again!

A step up

Been using Apollo units for about a decade. Started with silver, then black and now the X8. I find both the monitoring and recording conversion of the X8 a step up from the previous generations. Very, very clear, no graininess. Very pleased!

A bigger difference than I originally thought…

All I can say is…wow! I didn’t think that the difference from the Blackface Apollo 8 to this would be as significant as it is. Improved A/D and D/A conversation, better depth and stereo imaging, and more DSP are all things this x8 improved upon! Well worth it!

The sound has changed dramatically

 I used to use the Apollo Duo, but the sound has changed dramatically compared to that, and I can now see the sound of the synth even with fine particles. If in doubt, buy it.

Beautiful sound quality

I upgraded from an 6 year old USB Twin and the difference is far more than I expected. I wasn't sure about the sound of the highs but I gave it a couple days for my ears to adjust. The sound stage is wide, deep and detailed in a whole new way. Love listening to everything all over again. Creating and mixing is going to an absolute pleasure with this for years again.

Awesome

This sweet , real user friendly and I used the unison with the neve mic pre and the 1176 on insert in the uad console and the artist was amazed of how balance his vocals sounded in the daw without even starting the mix and also tracking without latency...the io options are nice headphone amp is good. Haven't tried the converters as yet but I'm sure it's good because the unit is good..not up grading for another 8 years

Everything I Hoped for -- and More

I was not looking forward to going through the upgrade to a new Interface/ DAW system, but man am I glad I did! The process was much smoother than I feared thanks to the Universal Audio on-line guidance and the intuitive design of the interface. Every day I am impressed by the power and audio quality of the Apollo x8. I highly recommend this interface to those considering stepping up their game.

Fantastic!!

Having upgraded from an RME UFX, I wasn't expecting such a significant jump in audio quality but the difference was stark; the clarity was there, but without the overly harsh top-end that you'd normally expect with devices that deliver clarify. The sonic response throughout the frequency range made my mixes far, far more coherent from the 1st and 2nd pass, rather than endlessly having to fight a mix just to be able to hear the various elements.

No surprise

No surprise how good this unit is and how great it sounds. After years of Apollo desktop version, I finally switched to a rack unit and I love it.
Really good preamps, so many inputs and outputs to accommodate recording studio on every level. Easy to use front panel, console software is great and im still learning how to use it properly. Overall nice unit and happy with the purchase. Looking forward to using it with LUNA. Big thanks to the Universal Audio team.

Could have started smaller,... So glad I went big!

This is my first step into the world of UA and after much deliberation between the Duo, Quad and x6, I slowly realised the x8 would do everything I needed it to do and more in the long term so I took the plunge.

Right now I needed a workhorse to sit as a centrepiece in the studio, handle everything from creative music, audio post production, surround sound, live-streaming, and would also be able to capitalise on other redundant interfaces through ADAT. It does it all! The unison pre-amp quality is absolute gold, definitely a top job! It has been a perfect pairing to a certain new silicon chip that has landed in my studio.

Console is powerful and completely quashed the need for buying any 3rd party audio routing apps. Setting up my monitor A/B was pretty straight forward. Surround Sound was also a breeze and i'm yet to attempt a custom 5.1.2 atmos custom configuration. I love that you can save all your configurations from within console. Customer service has also been great and prompt to help figure out a few plugin authorisations, other than that it's so familiar and straight forward! Love it!

My previous rack-mounted interfaces were not low end, but I was blown away by the Apollo X8 on my first recording. The clarity is amazing. It has also taken substantial load and latency off my primary system. Very happy.
