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.

I love Apollo but...

I just upgraded my Apollo silver TB3 to the new 8x Heritage edition.
In got only 5 old plugins while I own most of the Heritage edition.
And worst than that 1 of the headphones output is not function well.
The reseller already bought me a new 1 but I was very disappointed to be in that situation.
In that price I except to perfect condition Apollo and more plugins for those who already own most of the heritage bundle .

A game changer

I've been using RME and Waves pluging for about 15 years.
Switching to Apollo and UAD plugins is a real game changer for me. I'm thinking about selling half of my analog recording equipment.
Ok, it's expensive but it's worth every dime I spent !

December 29, 2020

Yeap

Pretty happy overall, I'm still learning to use it though. I do believe there's an improvement in sound quality from the focusrite clarett I was using . I wish they give us a promo code for plugins considering all the money it costs, but I'm still happy.

Apollo X8

I exchanged Apollo 8 to Apollo X8.
I have had my old unit for 5 years without any troubles.
I used my old unit a as digital mixer for my hardware and software synths and for my guitars and I thought this should be the ultimate tool for creating music.
I was able to test Apollo x8 and I was surprised that the soundquality was so much better than the old unit. I decided to get Apollo X8. I was lucky to get a good price for the old unit .
I Have had Apollo X8 for three weeks now and I am still surprised of the soundquality. The build quality is exellent, it will last for many years.

Perfect for anything

It’s not my first Apollo. I’m very happy with my purchase. It’s very flexible interface. Also with 6 sharc chips it’s very powerful. I also combined it with a Satellite. Dynamic range and coverter quality is really good. If you have a budget don’t waste your time by overthinking about pulling the trigger :)

Just a shitty attitude

Cool but there is something MISSING

Cool interface, cool sound! But to me it is far away of understanding why it can handle only 8 channels of ADAT at 44,1 kHz. This is quite an show stopper to me.
Let's say you own some other interfaces you still want to use. In order to use the console features (e.g. using the inserts only for tracking but not for writing) of the UAD you have to have to choose the UAD as the asio driver in your DAW. I now expect an interface at this cost with two ADAT IN/''OUTs to provide me 16 channels at 44,1 kHz for connecting my mic ins of two ohter interfaces for recording.
Another thing making my head shaking: when using this interface along with other interfaces (one of them is the clock master) and setting the UADs clock source to ADAT (because it is connected via ADAT to the clock master), you still have to set the right sampling frequency MANUALLY at the UAD device.
Both, lack of ADAT-IO and sampling frequenz syncing seems to be very old fashioned. Please give me 16 44,1 kHz ADATA IN/OUTs! I do not need to treat them with UAD-plugins, so no horse power is needed here.

Broken Apollo and no assistance

My Apollo, which sits safely in my rack far from anything that could damage started malfunctioning for no apparent reason and customer care did next to nothing to help. Beware if you buy this and anything happens UA will not stand behind their 3,000$ product as they should. Now I am shipping mine back to Sweetwater, who generously offered to fix it out of warranty (still for $$) because they sold it to me and felt bad. Unfortunately that means a six week turn around time and cost of shipping so now i have to buy a new interface so my studio doesn't have too much downtime and i lose income. I'm incredibly frustrated having now had to pay the money to ship and repair the Apollo and now potentially buy a new one when i did nothing wrong in the first place. And still no one from UA will return emails or reach out to me. This is a fine interface but you may want to seriously consider buying from a different company, one who makes an interface that doesn't break out of nowhere and then won't help you

Stunning interface

The sound quality of the pre-amps as well as the DA circuits is superb. It's clarity and open an tight low -end impresses. Came over from other brand which I used for 10+ yrs but the sound difference is stunning. I did some vocal recordings with unison pre-amps enabled and it blows my old interface away. The unit is build to last long (I hope). Thumbs up.

Finaly one that does all good

It was time for an A quality sound device. The Apollo x8 sounds perfect and working with it feels effortless. I'm waiting for my satellite and then I'm done for a while. I have everything I need to record myself and any band. Oh wait still have to choose the plugins that suit my style.
UAD thx for great gear
