Four Pres Plus Unison Technology!

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.

  • UA 610-B

Stop searching. Buy this now.

This is the only way to run Pro Tools (native) and/or Logic. There is no shortage of great interfaces these days and most can get the job done but.... using this with no regard to latency (on board processors take care of what you could ever want going in) and best in class audio conversion AND the best plugins on the market make it a no brainer. Save yourself the time and buy this.

The Apollo 8...Simply Great!

We are so fortunate to be in this era of technology and the impact it has had on Home Studios. I have gone from analog tape to digital and during that transition there was something clearly missing. With UA's Apollo 8 and the UAD-2 platform we have not only gained the warmth of analog but we have surpassed the audio quality. The 4 Unison pre's on this unit are pristine and using the Unison technology to track with a Neve 1073 Preamp and EQ for example is outstanding. You can bypass the Pre's however if you wish if you own a great standalone pre. I am very excited about this product and feel like I have what it takes now to push out some quality productions. Be sure to get enough DSP however as I find myself reaching more and more for the amazing plugins like the Manley Massive Passive Eq. Outstanding sound and space that it creates. Additionally I have purchased the Apollo Twin Duo which works great together with the Apollo 8...I am able to keep the Twin on my desktop and use it to quickly adjust line and volume settings. Universal Audio is one of those companies that simply satisfies me as a consumer. Amazing quality and the support is great! Thanks to Tim Harrington for getting my order so quickly and making this purchase a great experience.

Awesome.

This box sounds and looks fantastic. Worth every penny. The only thing to consider is getting the higher DSP models or a satellite - if you're trying to track a good number of tracks with some of their higher DSP intensity plugins running, you'll be wanting more power.

Perfect

I couldn't be happier withe the Apollo 8 Duo. I'm using it with AKG C414's to record my grand piano and the sound is great. It's like night and day over what I had before. The unit is user friendly and the console software works great. Although the quad is quite a bit more, I kind of regret not getting it because the processing power gets used up pretty quickly with plugins. If you have the extra money, go for the quad.

First Rate Interface

Hardware:Great mic-pres. (With or without Unison plug-ins). Versatile routing options—especially for monitoring: alternate speakers, sum-to-mono. A/D and D/A converters are extremely accurate, with stable clocking.Software:The UAD plugins sound fantastic. I especially love the Unison preamp modeling technology. Admittedly the DUO does not have as much processing as I would like, but that's the tradeoff I made for the price. Of course, the nice thing is that you can daisy-chain UA interfaces and DSP Satellites.The Console software is also incredible useful. I've worked with a range of large-format consoles, including SSL and API. The Console program from UA takes many of the familiar controls from high-end hardware into the computer: routing, monitoring, cue mixes, and the ability to insert in either the channel or monitor path, to name a few.
