Get to know them!

Place the Universal Audio Apollo Twin X USB at the center of your studio, and it’s guaranteed to turbocharge your productivity. The Twin X USB’s performance rivals UA’s rackmount Apollo X audio interfaces but eschews extraneous features like 5.1 surround monitoring and +24dBu operation for a streamlined desktop design tailor-made for project studios. Track and mix with spot-on emulations of tried-and-true studio classics, thanks to UA’s powerful onboard processor. Experience top-shelf sound quality by way of the Apollo Twin X USB’s upgraded elite-class AD/DA conversion. Dual Unison preamps allow you to track through models of the industry’s most legendary gear. The Apollo Twin X USB Heritage Edition comes with a premium suite of five award-winning plug-in titles, along with the Realtime Analog Classics bundle, arming you with accurate emulations of vintage analog hardware. Beyond that, you get sub-2ms latency and ample expandability, thanks to the Apollo Twin X USB’s ultra-fast USB 3 connectivity. If there was ever a time to upgrade your Apollo Twin, then now’s the time!

Note: The Universal Audio Apollo Twin X USB is compatible with Windows-based computers only. It will not work on a Mac computer.

Track and mix with this Apollo USB’s powerful UAD processing

There are times when your computer doesn’t have enough power and speed to run all the plug-ins your recording session requires. That’s where UA’s powerful UAD processing comes in. This processor enables you to track in real time with Neve, Manley, or API channel strips or run large UAD plug-in counts while mixing in your DAW. The engineers here at Sweetwater appreciate being able to inject guitars with the tube warmth of a Pultec EQ, add the musical limiting of an LA-2A to a vocal, and pump up drums with an 1176 or a Fairchild 670 — all in real time. It’s the closest thing to having the real hardware.

The Apollo Twin X USB Heritage Edition audio interface includes a generous range of producer-approved UAD FX plug-ins
The Apollo Twin X USB Heritage Edition leads its class in both A/D and D/A conversion

Elite-class AD/DA conversion offers ultra-pristine sound

Apollos have always sounded great, but the Apollo Twin X USB’s AD/DA conversion takes it to the next level. When they were designing the latest generation of Apollos, UA engineers auditioned the latest leading-edge AD/DA technology, ultimately pairing elite-class 24-bit/192kHz converters with overhauled analog circuitry. The result is an ultra-pristine signal path with a 127dB dynamic range. Dive in, and you’ll hear it for yourself — the Apollo Twin X USB’s AD/DA rivals any high-end standalone converter on the market.

Capture the sound of legendary preamps with this Apollo Twin USB Duo’s Unison technology

The Apollo Twin X USB’s Unison preamp technology goes so far beyond traditional software modeling and emulations that it’s really in a category all its own. Essentially, Unison is a bidirectional communication between the Apollo Twin X USB’s mic preamp and a Unison-capable plug-in, such as the included 610-B plug-in that re-creates the sound of UA’s classic 610 tube preamp.

The plug-in actually adjusts the preamp circuit itself, including parameters such as impedance, analog gain structure, and much more. When you adjust the Apollo Twin X USB’s preamp gain knob and physical controls, the plug-in adjusts the preamp’s behavior to match the target preamp. So, you’re not simply filtering your audio to approximate the character of a famous preamp — your microphone is now interacting with the Apollo Twin X USB’s input the same way it would behave with the “modeled” preamplifier.

UAD plug-ins astounded the recording world with their incredible ability to sound like analog processors, eliminating the need for large racks of gear in the studio. Unison preamp technology will do the same thing for your mic inputs, eliminating the need to collect and maintain expensive hardware preamps just for sonic variety.

Zero-latency Unison reamps add instant color to your signal path
The Apollo Twin X USB HE packs some serious onboard DSP in order to drive those hardware-emulated UAD FX plug-ins!

Sensational plug-in bundle included!

UAD Powered Plug-ins have earned a reputation for being some of the most accurate emulations of analog audio equipment ever created. The astonishing processing power of the UAD platform is what makes these plug-ins sound so great. You simply can’t get the depth, color, and character these plug-ins have without devoting huge CPU resources to them. Best of all, Apollo Twin X USB lets you record your audio through UAD plug-ins in real time with sub-2ms latency. When you buy the Apollo Twin X USB Heritage Edition, you’ll receive a premium suite of five award-winning plug-in titles:

  • UA 1176 Collection with three unique versions: Rev A, Rev E, and AE
  • Teletronix LA‑2A Classic Leveler Collection of three historic versions of the revered electro-optical tube processor

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
