Get to know them!

Combining a world-class analog front end, cutting-edge conversion quality, and the unparalleled power of built-in UAD-2 QUAD plug-in processing, the Universal Audio Apollo QUAD FireWire audio interface represents a new approach to recording. Over 10 years of research and development have gone into making the Apollo QUAD, and it could change the way you operate in your recording studio. The Apollo QUAD gives you built-in UAD-2 QUAD DSP to let you track, mix, and master with acclaimed UAD-2 powered plug-ins — with near-zero latency! UAD-2 powered plug-ins serve up incredibly realistic emulations of classic studio processors, so you can get the sound of iconic analog equipment on your tracks, with the convenience of plug-ins. And with the Apollo QUAD, you have the DSP power you need to run an array of these top-notch plug-ins with ultra-low latency, while your host computer runs your DAW.

Built-in UAD-2 QUAD DSP for running UAD-2 powered plug-ins

The really big deal with Universal Audio's Apollo QUAD is the built-in UAD-2 DSP, which lets you run UAD-2 powered plug-ins without having to install a separate processor card in your computer. UAD-2 powered plug-ins have earned a worldwide reputation for being some of the best-sounding, most accurate reproductions of classic analog studio gear. With UAD-2 DSP power built right in, you can track, mix, and master with UAD-2 powered plug-ins with near-zero (below 2ms) latency. This type of performance was previously only available on expensive and complicated DSP-based recording systems — Apollo QUAD makes this pro-level performance accessible to home and project studios too!

Premium analog signal path

Apollo QUAD began with Universal Audio's vision of the perfect marriage of analog equipment and digital recording technologies. You'll capture rich, vibrant audio from the four built-in microphone preamps, and two JFET instrument inputs let you capture sweet direct-instrument recordings too. With a total of 18 inputs and 24 outputs, the Apollo QUAD has the connectivity you need in a professional environment. And because UA focused on creating a pristine analog signal path, you won't have to buy racks full of analog preamps just to get a great recorded sound.

A powerful foundation for any recording, mixing, or mastering studio

Universal Audio's Apollo QUAD is a significant advancement for any pro-audio application, whether you track, mix, or master in your studio. UAD-2 powered plug-ins have been acclaimed for their analog-like sound and vibe, and with the Apollo QUAD you can track with these plug-ins with ultra-low latency. You can reproduce the signal chains of the world's most famous recordings, without spending tens of thousands on analog hardware from 40 years ago. When you're tracking, that means you can capture a better recording right from the beginning, and your artists will love the high-quality sound of their monitor mix. During mixing, UAD-2 powered plug-ins give you all the tools you need to produce world-class mixes without compromise. And for mastering, UAD-2 DSP technology gives you access to more emulations of history's greatest mastering processors than any other platform does.

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 QUAD'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.

Thunderbolt-ready for PCIe-like speed and bandwidth

Apollo QUAD's Thunderbolt expansion port allows you to add Thunderbolt connectivity (via an optional card) to your Apollo QUAD. Based on PCIe technology, Thunderbolt offers a much-higher bandwidth connection than USB or Firewire, and with lower latency too. While Apollo QUAD already sports incredible sub-2ms latency with its Firewire 800 connection, Thunderbolt lets you record more tracks at higher resolution with ease.
