Arturia Rev2 USB Audio Interface. Used only in my home studio as my primary interface for the last few years. It has a lot of different I/O options. Also very nice if you are using a laptop and don't have room for as many connections to say things like a mouse, keyboard, etc as this has 2 extra slots for something like that. Would be a great interface to travel with although I have never used it like that. Further description below for specifics and details. This is no longer in production but still supported from Arturia so it's a great chance to get your hands on a convenient desktop interface without going to there bigger flagships. Still has all the same mojo though.

NEXT-GENERATION AUDIO INTERFACE

You're making tomorrow's music... so why settle for yesterday's interface? AudioFuse is the revolutionary pro audio interface that sets a new standard in sonic quality, creative production and value. It fuses the superior sound of high-end analog studio consoles with the flexibility of a solid mobile interface—with all the connectivity you need for any recording or performance.THE SOUND

Whatever sound you need to capture, from the most delicate ambience to the heaviest cacophony, AudioFuse will reveal the beauty in everything.

Pro studio quality was our mantra right from the start with AudioFuse. Now you can transform your desktop, hotel room, concert—whatever, wherever—into a studio with world-class sound.

No compromises, each element of the AudioFuse has been selected to perfectly serve your sound, such as the two proprietary DiscretePRO® microphone preamplifiers and the set of top-notch AD/DA converters.

Saving the purity of your sound and the passion it conveys is what AudioFuse is all about.

CREATIVE FLOW

When creating and recording, you need an interface that lets you focus on the task at hand and keep distractions to a minimum.

With AudioFuse, we didn’t want to settle for merely bringing you the sound quality of a pro studio, we wanted to bring you its workflow too. That’s why you have detailed metering, talkback for instant communication with talent in the next room, inserts to add professional effects processing to your recording chain, A/B monitor switching, and direct access to the essential features so you can spend more time creating and less time setting up.

THE CONNECTIVITY

Wherever it comes from, whatever it has to travel through, and wherever it needs to go, AudioFuse will guide your sound.

AudioFuse connects with virtually everything: mics, instruments, turntables, studio equipment, Mac, PC, tablets, even iOS and Android phones. It all happens with a round-trip latency as low as 3 milliseconds so you'll feel right in the groove every time.

PERFORMANCE

When you know your equipment is the best of the best, creativity can take care of itself.

When it is all about giving the best of yourself being able to rely on the best technologies becomes crucial. The lowest harmonic distortion, the most linear frequency response, the highest signal-to-noise ratio and the shortest latency, these technical terms may seem far removed from your creative process, but they are essential to delivering your music in the highest quality possible.

THE QUALITY

Capture the moment—at home, in the studio, on the road, or wherever creativity strikes.

AudioFuse has a super-solid aluminum chassis you can trust, complete with a hard cover to protect it from damage in your bag—or even just dust on your desktop. The build quality goes far beyond a great-looking exterior, as well. Your unit has to pass rigorous testing before it can be packed and shipped. It even comes with a test specification printout of your exact unit. Meet your new best friend for the studio and stage.

A perfect production bundleAudioFuse Rev2 also includes AudioFuse Creative Suite, a superb collection of software effects and instruments that’s constantly growing with titles from Arturia’s “You’ll Actually Use” series and Analog Lab Lite. AudioFuse Rev2 not only gives you everything you need to record top-of-the-line audio, it also gives you legendary effects and synth sounds to enjoy. This will be also the case for current AudioFuse users.
