Elite Audio Conversion and Unison Preamps, on your Desktop.

Apollo Twin X allows musicians and producers to easily track, overdub, and mix with elite-class A/D and D/A conversion, two Unison-enabled preamps, and available DUO or QUAD Core realtime UAD plug-in processing — all in a desktop Thunderbolt 3 audio interface for Mac and Windows.

Built upon UA’s 60-year heritage of audio craftsmanship, Apollo Twin X confidently outperforms everything in its class with 127 dB D/A dynamic range, along with an included bundle of UAD analog emulation plug-ins and LUNA Recording System, giving you a fully-stocked analog studio, right on your desktop.

Record and mix with elite-class A/D and D/A conversion — with the widest dynamic range and lowest noise of any desktop interface

Two Unison-enabled preamps — track with near-zero latency through preamp emulations from Helios, Neve, API, Manley, and more*

Onboard UAD processing lets you track and mix in realtime with included Teletronix LA‑2A and 1176 compressors, Pultec EQs, 610‑B Tube Preamp, and more

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

Two Unison Preamps: Get the Genuine Sound of Neve®, Helios, API, Manley & More

Apollo Twin X features two Unison-enabled mic preamps, letting you track through exacting mic preamp emulations from Neve®, Helios, API, Manley, Universal Audio and many more. Exclusive to UA Audio Interfaces, 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 UAD DUO or QUAD 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.

Elite-Class A/D and D/A Conversion

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 used to track exceptional-sounding records every day. To improve on the previous generation of desktop Apollo interfaces’ class-leading audio conversion, UA engineers redesigned the Twin’s audio conversion to deliver a striking 127 dB dynamic range and -117 dB THD+N, giving Apollo Twin X a spacious, organic sound that easily rivals dedicated high-end converters.

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. The Apollo range of interfaces has earned numerous industry awards from Sound on Sound, Future Music, and Electronic Musician — as well as the prestigious TEC Award for computer audio hardware five years running.

Apollo Twin X

Overall Rating

I've just updated my system with a twin X and I am delighted by the sound of this beauty. Very simple to start working with it. If you want to use some of your plugins into your DAW, you should, nevertheless consider to grab a UAD 2 Satellite Thunderbolt 3. But the plugins sounds so good, that it will be worth doing so !

Perfect Audio interface for small professional studios with no rack-mounted devices

I recommend the Twin X because it has elite technology built in like the Apollo racks and also has the amazing Thunderbolt 3 technology which is superior to Thunderbolt 2 technology. TB3 has more speed and is MUCH easier to connect, no Adapters are needed.

There are flaws to this product but UA are so ahead of the game that it doesn't matter too much. If you are a serious music producer, Get the Twin X as a minimum.

Simply The Best!

I started music production 2 years ago. Throughout that time Ive researched over a hundred hours comparing different interfaces as well as sound comparisons. In my humble opinion, UAD has the best sounding plugins to my ears and that is why I chose to invest in the UAD platform. Sure the DSP loads on some plugins are sometimes are less than ideal however I personally would not want to compromise sound quality and when I listen to other plugins, it just doesnt sound right. Thank you Universal Audio for providing such quality for ITB mixing and unison tracking

An Amazing Product!

This is the best in its class. Sound quality is far superior to the competition. Build quality is excellent! Very sturdy! Features well thought out! It’s true that the converters and sound quality is better than device costing 10x its price. To top it all all its a portable size. Great for project studio’s, songwriters, musicians, and producers.

Now, you can do more and not worry about toooo much...GREAT!!!! JOB

All of the UA hardware is magic. I wish I had one. They sound amazing. I wish I had one. The build quality is second to none. I wish I had one.

I've been in the music industry for more than 30 years and being a studio/live bass player has given me the opportunity to test a diverse amount of gear, including preamps and audio interfaces and this guy (Apollo Twin X) has been definitely a revolution piece of gear, a next step in quality, a strong upgrade to any home or state-of-the-art facility. Simply an amazing machine!

Amazing interface minus the manual removal of 175 demos

This interface is amazing. The only negative is having to manually remove 175 unwanted demos. Please just give the option to not download them OR at least have ones you own highlighted in bold or coloured text.

Windows WDM still not working

I am not giving this one star because if you are able to us ASIO drivers and don't need your computer for anything input related using the WDM drivers, it is awesome. If you're like me and need your computer for Zoom and other programs that require a microphone on Windows, don't buy it.

This is the best audio interface I have ever used. Dumped my Apogee Duet for it. Easy setup and use. Haven’t fully explored the software yet but am getting there. I prefer their vision of offering the software for free and buying the pro plug-ins as needed in tidy bundles. I am beginning to hate any software that forces an annual membership fee to use it. Keep up the good work!!

Amazing Gear and Plug-Ins

I was a little hesitant to switch from my Protools set up to the Apollo X Quad for my interface but as soon as I put Audio through the Apollo X, I could absolutely hear the Clarity difference. So Glad I made the Change!! Thank you UAD!! Keep up with your Outstanding products.

twin x duo

In my opinion 5 stars because hw components and plugins are amazing. This is my first AU interface. I found it very easy to install. Great documentation. I like a lot guitar amplifier emulation with unison. The best experience never tried. I agree with UA about the choice to have in this little interface same hw and features as the bigger ones. Is just what I was looking for. The price is adeguate to this features. Nice idea the block system implemented on the power connector. To make the most of your product i found the advice on your youtube channel very useful. The support seems to me very adequate. The interface must be placed on a hard surface to allow dissipation of the heat generated. After hours of work the max temperature measured was 36,5°C on the right side. The opposite side was at 33° Celsius (environment temperature at about 20°C)

Un cambio real

The spanish comment you're looking for . Compre esta interface por que pensé que seria un cambio , un upgrade en mi producción , pero honestamente fue mas que eso , realmente es un cambio en todo aspecto , puedo escuchar una mejoría en todo sentido. Si puedes ahorrar para comprar una de estas , HAZLO. Con los Pre Amps , Avalon , 1073 , 610 , la mejora es abismal en términos de grabación , un nivel que anteriormente no logre jamás con mi antigua interfaz ( la roja ) , interfaz que por lo demás no es para nada mala . Estoy feliz con esta interfaz 100% !

Incredible and amazing! It has always been my dream to have the analog gear UAD has produced over the years, with the Apollo Twin X now I have access to the most amazing gear I've always wanted!
