UA’s Flagship 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 133 dB dynamic range and THD+N of -129 dB, the Apollo x16’s open, natural sound quality bests every interface in its class — regardless of price — and is the perfect starting point for applying UAD processing.
Realtime UAD HEXA Core Processing
Apollo x16 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.
A Full Suite of Classic Analog Processing Onboard
Of course, 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 x16 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, Pultec EQs, and many more.

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.
“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)
“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)
“The Apollo 16 is the most stable, sonically accurate addition to my studio by far. Its incredible metering, monitor control, and the Realtime UAD Processing make it a game-changing interface.”
– Darrell Thorp (Beck, Radiohead, Charlotte Gainsbourg)
“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)
“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)
“My Apollos are my sound.
Where I go, they go.”
– Trevor Lawrence Jr. (Dr. Dre, Herbie Hancock, Eminem)
“The Apollo is the best I/O we've ever used, and we've tried them all. It has an incredibly clean, transparent, and accurate sound.”
– 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 16 is the most versatile and reliable interface we’ve ever worked with, both in the studio and on stage.”

Best on the market for the price!
Absolutely fantastic! I use it every day. I have an API ACS Legacy console and I run it into two Apollo z 16s. Sounds incredible!
So glad I made the transition to the UAD / Apollo environment. Sounds great and the near zero latency when tracking is invaluable. Great clock and great sounding AD and DA conversion. Two thumbs up.
The best, that’s all
Middle of the road
This interface is expensive , I’d say the quality is what you would expect from China where these seem to be made at .
The best of the best!
Its sound is AMAZING..... EXCELLENT.... and the combination with the Dangerous 2 Bus Summing it is simply spectacular. The best upgrade to my studio. Making the connection between my apollos and the hardware was extremely simple and easy .... Thanks!
The best of the best!
Great unit. Will be more better when I will be able to connect my external hw compressor and etc. via insert in LUNA (I bought it for this aim)
Great interface, was using three 192’’s for years...what a difference! Wish I had done it years ago. All I can say is awesome.
A MUST!!! UA Mojo
Audio quality is amazing. Definitely worth investing!
Looking for top Quality?
Apollo x16 is the best audio interface ever.. no competitor at all
King of interfaces
It doesn't get much better than this. It sounds fantastic, and recording through realtime plugins is a fantastic workflow. Connected to my desk with my X8 I get 24 channels of analog summing on mixdown, with first class sonics. What's not to love!
UAD Apollo x 16
Does NOT Have 16 Out (Without Workaround)
I see another review saying this, and I've seen other people talking about it but seriously: What in god's name is the point of limiting the "flex routing" to 8 out channels? Why would anyone buy a 16x16 piece of gear... that can't use all 16 outputs without some weird workaround using the Cue busses? UAD's explanation is "latency" but that makes no sense considering you CAN assign the last 8 outputs with that workaround (and we're getting no latency doing so).
At least it works and we didn't waste time and money for nothing and the workaround exists, but this is some seriously false advertising. You should be able to freely route to all the channels if you need to do so from the Console, and if not there be a humongous asterisk up on this marketing material about this limitation, not something buried on page 92 of the manual.
A Great Step Up
Definite increase in converter quality since MKII model. Great being able to run at +24 as I can drive my preamps harder before clipping. Fantastic to have 50% more DSP.
Chains perfectly with x8p and x4 for a fully fledged system.
Flagship unit of the industry leader - you cannot go wrong.
its a must have for tracking or if u choose to use analog gear with it. It was a lil confusing at first to set up the I/O but once i got it figured out it was a dream... the sound, conversion and clarity is top notch!
I purchased the Apollo X16. It has excellent preamps, which is why I put 3 stars.
The negative is the routing section related to the X16 console. It does not allow monitoring of 16 inputs on 16 separate outputs, but a maximum of 16 inputs on 9 outputs. The problem can be solved a bit by using the "CUE", but it is not a normal thing for a 3500 euro card. Big disappointment.
To improve the DSP management with different plugins, since for example if you want to insert only one "Neve 1073" for each channel, the dsp is not enough to cover the 16 channels of the card.
apollo x16 music good
Great audio solution
Apollo 16 x
So far so good,using it with my api 3208,which means i will be looking forward to adding another one in the near future,great job with luna.
Playback - Mixing in Hardware - All the Good Pro stuff!
Yes, this is the real deal - the move up from project studio to studio studio. Expect to spend another $600 on cables but the DA converters are worth it. And now routing in Pro Tools is a cinch with all these channels to use in stereo or mono.
I have chained my existing x8 to it and it was fairly easy to setup in Console (start with SingleProToolsX16 preset and then add the 8x and save as a new preset. I choose the x16 as the monitor device and I'm not sure why anyone would choose different since the DA converters are supposed to be better in the x16
I have not been completely impressed with UAD plugins or the Unison preamps. Don't get me wrong, they are both quite good. However even my least expensive hardware preamp is better and not only are there native plugins that are as good but at least FabFilter is less of a drain on the CPU despite the hexa chipset.
That said, I bought the x16 for it's superior converters and work flow. I don't think there is a better hardware user interface available and the converters have not disappointed. I have started experimenting with Luna and the sound quality is impressive, this is where the UAD plugins, especially the tape ones, really start to shine. Can't use it, of course, until it gets hardware inserts but I'm excited about the prospect.
At a certain point in my studio development I came to a point where I thought I had to decide "Great interface or summing mixer". With the x16 and mixing through hardware, I have both. After reading other reviews here, I'd say get a Mac if you want to use this without problems.
