Elite-Class A/D and D/A Conversion
With thousands of hit 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 interfaces’ 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 x6’s open, natural sound 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 x6 features 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 electronic musicians and post production professionals who don’t require tons of mic inputs, Apollo x6 features two 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 Onboard
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 x6 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.

Access the World of UAD Powered Plug-Ins
Going beyond the included Realtime Analog Classics Plus plug-ins, Apollo x6 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 Neve, Studer, Manley, Helios, API, Ampex, SSL, 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 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)
“I'm really impressed with the Apollo X8. I hear more detail in the several sets of monitors I use, and I'm getting that little bit extra out of the Unison mic pre emulations – and they were already extremely close.”
– 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)
“My Apollos are my sound.
Where I go, they go.”
– Trevor Lawrence Jr. (Dr. Dre, Herbie Hancock, Eminem)
“Apollo is a platform that grows more powerful with every innovation – the UAD plug-in processing onboard has changed the way I work forever.”
– Tony Platt (AC/DC, Bob Marley, Buddy Guy)

– The Glitch Mob
“I’m totally blown away by the stunning sound quality of the Apollo. The ability to use UAD plug-ins in real-time is pure genius. It’s the centerpiece of my new studio.”
– Richard Devine
“The Apollo's ability to do low latency – I mean that's the whole ballgame right there.”
– Joey Waronker (Atoms for Peace, Beck, Other Lives)
“The Apollo is a powerhouse and a game changer for my studio.”
“Using my Apollos and Console 2.0, I'm able to front a live mix, create a monitor mix, and record, all at the same time. That’s pretty awesome.”
– Chris Dugan (Green Day, Iggy Pop, U2)
“Having the Apollo with UAD plug-ins at my disposal is like carrying a giant studio with outboard racks at all times. Minus the tech fees, down time, and electricity bill!”
– Andrew Dawson (Kanye West, Jay-Z, Fun.)
“Apollo's A/D and D/A conversion sounds incredibly detailed, with great clarity and a tight, punchy low end. And with the Console 2.0 app, I have all of the routing and monitoring options I need.”
– Dave Pensado (Justin Timberlake, Beyoncé, Maroon 5)
“The Apollo x8p is the workhorse for the majority of our mobile sessions. The flexibility is crucial to our workflow and once you’re familiar with the front panel controls and Console software, it becomes a seamless experience that allows you to truly craft your sound.”
– Mike Larson (Pharrell, Ariana Grande, Migos)
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.

Zero latency changed the way i record guitar, direct in to Hi-Z with amp plug-in does the job perfectly.
Awesome audio interface
Very professional interface for home and professional studios too. It is the treasure of my home studio, works fine with Pro Tools and Mac OS Big Sur. I love it!
Since bringing x6 home, it's been clear I made the right choice. My options in interface upgrades were few, and the list was quick to come to the Apollo x6 as the stand-alone option. I've been using it daily as the head of my studio, and have yet to be disappointed. This thing is Clean and Fast. The bundled plugins are amazing. If I had to go back and do things over, the only thing I would do different would be to get the Apollo sooner.
Wish I purchased this sooner!
Before this I’ve owned both Motu and Apogee interfaces over the years. Switching to the UA Apollo was like upgrading to a Rolls-Royce. Worth every penny and then some. It also pairs perfectly with my SSL Fusion with the +24db of headroom. The Unison pre is a great feature as well. I immediately purchased the Neve 1084 to run my Moog Sub 37 through it. Sounds so damn good! I’m hooked. As a Scotts Valley resident it also feels good to support a local business here as well. Rock on UA!
The Apollo x6 is an intuitively flowing piece of gear that provides a utilitarian intermediary bridging the 1 and Zero digital landscape with the hands-on, knob-turning dimension of physical reality. An elegant tool, a quality design of magic that enables you to create your potential. Way stoked, although now I feel the strong need to re-record everything I did before having the x6 ...
One of the best Purchases for my music career I have ever made
I feel this is one of the best Purchases for my music career I have ever made. For anyone who owns a Solo or Twin and Universal Audio Plugins but hasn't experienced the Apollo x6 or above product lines you will be amazed with the sound quality. For example I have always liked the UA SSL E Union Plugin. While on the Apollo Twin is was impressive and I was thrilled with how it sounded on the Apollo X6 platform. It was like additional detail came alive. Thanks to the Apollo X6 my mixes have gone to the next level.
In love I’ve had for a week now and the sound Apollo for life...
I had every rack model in my studio setup from ever, this Apollo X6 is very good too, but I'm disappointed about the incopatility with Apple Silicon Chip...
Once an Apollo user there's no going back
I've been running an Apollo system for the past decade and have come to rely on it's quality, stability and excellent UAD plugins selections and sounds. Lifer.
What a sound! but..
I upgraded from Apogee Duo to x6 Heritage Edition, and that difference in the sound is HUGE, but the only reason I give it 4 stars instead of 5 is that plugin sale tactic that forces all the plugins to be installed and show up in your DAW even if its unauthorized! its a cheap move and you are the only guys who do it, other than that its PERFECT :)
Sound is Godly
First of all I can’t explain how amazing the sound is! Especially using the unison plug ins. You get what you pay for and actually so much more!
Huge step up from Mkii Twin. Love the power, versatility and sound of this unit!
This is my 7th UAD gear. Nuff said!
Perfect Interface for ITB Mixes
Love it from first sight!
Sounds awesome! Mastering grade converters!!
Apollo X6 For Post Production
I just got my X6 to use as an interface for surround mixing for audio post production. It was an easy set up, sounds great and has been rock solid since I got it. I really love UAD hardware and plug-ins, they sounds great and are really reliable!
Exactly what you would expect
I have a couple x8’s and just wanted a few more inputs. Works just like the others. Added dsp, inputs and versatility to my set up. Love Apollo.
Went from USB 2.0 to thunderbolt… Seemless installation… standard plugins sound great… High price but definitely worth it.
Only interface that works solid with M1 Macbook Pro currently
I built a pc with thunderbolt but my pc was giving me some latency issues so I bought a macbook pro m1 13" and my current presonus quantum2626 did not support m1 chips yet so I got a twin x and worked out the box with no latency on pc or mac so I used it for 1 week decided it worked so well for my needs I bought the x6 and OMG this thing is the best and the ua plugins make you wave goodbye to latency issues and daw metering issues. I am still keeping my waves since Abelton 11 beta allows me to use UA plugins as native vst's on the front end in Abelton 11.
Mother of all audio interfaces
Until I started using UA interfaces I was always dealing with latency issues. My Apollo x6 completed removed that problem. So good
