Get to know them!

Universal Audio's Apollo line has been one of the all-time most popular series of audio interfaces Sweetwater has carried, and when you pick up an 18-in/24-out Apollo 8 DUO, we're confident you'll know why. Loaded with top-shelf digital converters and a pair of Analog Devices SHARC processors, your Apollo 8 DUO gives you pristine sound and access to a world of amazing UAD Powered Plug-in processors. When you combine that with its super-fast Thunderbolt 2 connectivity, you get extremely high bandwidth and virtually no latency, plus the capability to track with insanely detailed plug-ins. And if you ever need more I/O or DSP than your Apollo 8 DUO can deliver, the Apollo Expanded line makes adding on to your rig a piece of cake.

Second-gen signal path delivers superior sound quality

For many of us who first picked up an Apollo audio interface for the onboard UAD-2 processing, the impressive sound quality was a seriously nice bonus. Then again, Universal Audio has always been known for their top-notch analog gear. Now they've raised the bar again by upgrading the Apollo lineup's digital converters and refining the signal path even more. The results are absolutely astonishing, offering you superb stereo imaging at a level of clarity that gives your sound serious breathing room. Whether you buy it for the DSP, the high-speed Thunderbolt connectivity, or the sound quality itself, you're sure to be satisfied with your Apollo audio interface.

UAD-2 DSP delivers dedicated power for amazing plug-ins

Ask anyone at Sweetwater, and they'll tell you that Universal Audio's UAD Powered Plug-ins are some of the best-sounding virtual processors ever created. Apollo 8 DUO packs UA's super-powerful UAD-2 processing, which lets you use UAD Powered Plug-ins at below 2ms of latency in real time! That means you can record, mix, and master with some of the best plug-ins in the industry, without requiring any external processing. You can also use the Virtual I/O feature to process virtual instruments and DAW tracks in real time too!

Thunderbolt gives you ultra-low latency and unrivaled bandwidth

You haven't experienced low latency until you've gotten your hands on a Thunderbolt audio interface such as this Apollo 8 DUO. But the Apollo 8 DUO doesn't just benefit from the massive track count and less than 2ms latency ultra-high-speed Thunderbolt 2 connectivity has to offer, it also lets you track and record with extremely processor-intensive plug-in processors, all without experiencing any significant stress on your computer.

Unison Technology makes Apollo Pres mimic classic gear

No matter how good a plug-in emulation may be, there are just some things that software can't do. That's why Universal Audio developed their Unison preamp technology. Unison technology allows your Apollo 8 DUO to reconfigure the impedance, gain structure, and other physical circuitry of its four preamps as well as its instrument-level inputs to match the specific behavior of select UAD plug-in processors. As a result, your signal undergoes the dynamic saturation the original hardware would provide in the analog domain, long before it reaches the DSP-driven plug-in. The effect is a level of realism you simply won't get with standard plug-ins.

Real-time Analog Classics Plus bundle includes amazing UAD-2 plug-ins

You're ready to dive right into the world of UAD-2 plug-ins from the moment you install your Apollo 8 DUO's software. That's because Universal Audio includes their impressive Real-time Analog Classics Plus UAD-2 plug-in bundle, which provides you with eight amazing DSP-driven processors. In addition to vintage UA gear, such as 1176 and LA-2A dynamics processors, as well as preamp and EQ models, this bundle comes with hits from Fairchild, Pultec, and more. And when you want other amazing UAD-2 plug-ins, there are dozens of options, from SSL and Neve consoles to Studer tape machines and more all available in the UAD store.
