Apollo x16

Apollo x16

16 Channels of Elite Audio Conversion, HEXA Core Processing, and Surround Sound Monitoring.

The flagship Apollo x16 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 20 interface delivers the widest dynamic range (133 dB) and lowest THD+N (-129 dB) of any integrated audio interface on the market, all-new HEXA Core processing — yielding 50% more DSP for running acclaimed UAD Powered Plug-Ins in real time — plus it includes LUNA Recording System, giving you a fully-integrated music production application.

Record with UA’s flagship A/D and D/A conversion — providing 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

Easily connect to professional studio gear with 16 x 16 analog I/O via DB-25 connections, plus switchable +24 dBu headroom settings

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

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

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.

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.

The fantastic X 16

This is a super sounding device. Add 16 in-out and uad plugins. Suitable for production and suitable for creative work.

Apollo 16x

Love UA gear. So much so, I bought 3 Appollo 16x for my Trident 24A board. The only thing though, you'd think UA would throw in some plug ins. How can you not include the Plug-In Promotion Deal. And I bought three of them. Not happy about that. I'm told there's nothing you can do. If I hadn't already bought them I may have chosen something else.

Need true 7.1.4 Dolby Atmos capabilities...

I would love to see a redesign for the X 16 unit which will handle 7.1.4 Dolby Atmos for those of us who need it and we need it badly!

Apollo X16’s x3

Absolutely Amazing Converters, Cant beat the Sound Quality and Near 0 Latency. I Bought 3 for My Console and I Wouldn’t Go With Anything Else.
Although The Price Jump Over From around $3,200 to $4,500, And It Being EXCLUDED From the Apollo Rack Plug-In Promotion Deal Despite Being the Most Expensive Flagship Rack Mount Interface Without any Explanation Beside “Thats Above Us, We Don’t Know Why” really left me with a bitter taste in my Mount. Especially After Buying 3 of them!

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.

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!
