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.

Good as I hoped

Until now, I’m very satisfied with this thing.

New Interface, old plugins, no support.

Bought my 3rd UA Interface, this time Apollo X8..had to choose from Plugins I already bought a long time ago...no feedback from support for 3 days. Lesson learned.

R. Fluri

Sound, Utility, Plugins... unmatched!

There's so much to love about this interface, but the most noticeable thing for me is the sound, it sounds so wonderfully tight! Love the pre's, love the plugins, love the sound, love the look & just the right amount of in's and out's for me, super satisfied!

The best got better.

I have been lucky enough to own every generation of the Apollo interface and the X8 is by far the most versatile yet. It has all the processing power that I need "in the box" to run a small studio without necessarily having to rely on satellites. I cannot recommend this unit enough. The integration with Luna (as with all the other interfaces) is fantastic and has me considering ditching the DAW I have been using for years.

WoW!

Just like UA promotes it. It really feels like an analog studio during the performance. No noticeable latency whilst having the best sound AND less CPU usage on the host computer of the DAW - Love it!

It's just perfect!

I've been using a silver face Apollo (FW updated with TB 2 option card) for a decade now so you may say I'm a little committed. But look, there is nothing similar on the market that would come even close to this equipment (and the company as a whole).
We started to stream worship evenings with my band over FB during the quarantine and the Apollo FW become a little tight in terms of channel count and DSP as the band was growing. Now, the Apollo FW with TB 2 option card and the x8 work perfectly together. It took only like secods to daisychain the two brother (I'm using an iMac and TB3 connection). The system has a lot of DSP power. Basically, I'm using SSL E channel strip on each channel (percussion, acoustic and electric guitar, keyboard and vocals), some extra compression where it is needed and the EMT250 as a reverberator for this live situation. The sound is amazingly detailed and crystalclear even on the FB. Playing with in-ear monitors (4 different cue mixes with the two Apollos!) using this system is also inspirational for me and the other band members: you can hear such details that are nearly unheard with naked ears. The music is literally breathing.
Customer service and special offers are great at the UA. Big thanks for you guys! I become a huge fun of UA! Just in case (and because I like heavy hardware) I also own an LA-610 Mk II and a Twin Finity hooked up to the Apollo line in basically for tracking vocals and guitars. Digital heaven of sound!

APOLLO X8 INTERFACE

This is a fantastic interface. I had previously an Apollo Twin MKII Usb and I needed a bigger one because I have somw hardware to mix outside and with the X8 I have 8 line inputs and outputs which I found really interesting. Very professional interface with lots of features.

This added to my Universal Audio 4-710D Preamp allows me up to 16 channel of recording with ADAT extension.

I only find on very poor thing and it is that and interface of 2.700 € cost doesn't come with the Thunderbolt cable. This is something terrible that Universal Audio should include in every interface. The Apollo Twin USEB came with the USB cable.

I don't mind paying 80 or 100 € more in the price, but please, include the damn cable becaus if you don't have a cable at home you can't use it when you receive it.

Apollo Anxiety!

I rented the blackface Apollo 8 a few years back, and it changed my life. I had to return it and instantly got anxiety as all I had was a Focusrite to fall back on. So I just managed to scrape together for an Apollo Twin Duo and my anxiety was gone! Soon I added adat, but then was maxing out the Duo chips. So the choice was clear from there, I had to get the x8 to future proof connections and have enough DSP, I'll never look back. Massive UA fan for life!

Heaven!

This is the most amazing and perfect interface conceivable. I’ve been recording for twenty years and I finally have everything I need for a perfect recording and mixing workflow. I want for nothing more. This is far better than any Avid interface available. Thanks UA!

N. Watson

June 28, 2020

Absolutely excellent

This is truly an incredible audio interface. Its changed my entire production workflow and it looks and feels gorgeous. The only reason for the 4 stars is that the 6 cores in there do feel a little wimpy, I'd like to be able to run more plugin instances on it, and especially for the premium price it does feel a little odd. Regardless, build quality, 10/10, plugins, amazing, functionality, great, 2 headphone slots, so useful, and definitely worth it regardless.

Excellent machine

I am happy with this interface, its sound quality and features.
The knobs could have been better. It comes with a set of plug-ins that can keep you going for a while, although you will likely soon lust for more. All in all UAD offers the best system in my opinion... and now with the added bonus of LUNA: well done UA

S. Osman

May 28, 2020

For this money, it’s what I would expect from UA

It’s not cheap ! Is it , so I’m not going to rave like some lunatic about it .. the tech is excellent as I’ve come to expect from UA . It sounds great. I think UA could be more transparent about what you are likely to get plug in wise .. IF you already own UA hardware however .. as I can see others have pointed out , you may find you will get very little as you will already have most of them .
