An elite FireWire interface with 2 mic preamps, 14 ins/14 outs, 24-bit/192kHz HD conversion, and more.

Impact Twin is a state-of-the-art audio interface that features groundbreaking technology to ensure that the music you record sounds as good on the inside of your computer as it does on the outside. With the built-in preamp, converters, and recording tools, the TC Electronic Impact Twin offers a pristine path for your music to follow.

The interface's two mic preamps use TC Electronic's Impact III Technology which itself features three stages of top-level processing. You get a high-quality and very flexible mic preamp, superior 24-bit/192kHz HD conversion, plus a set of recording channel tools that lets you shape and optimize your sound making it the perfect recording. With each of these stages carefully combined behind Impact Twin's rugged and cool looking exterior, you have a FireWire interface you can take anywhere that offers the ultimate in recording quality.

The Impact III mic preamp makes the best of any microphone. Whether you record with the finest vintage tube mics, the most demanding low-budget condensers, or even a handheld dynamic, Impact Twin has been designed from the ground up to maximize the signal you record into your DAW. The preamps gives you maximum flexibility, and whether you're recording instrument, line, or mic; or with or without phantom power; the Impact Twin is one audio interface that works the way you need it to.

However, it's not all about the preamps. If your signal path doesn't then lead on to quality converters then you may as well pack up and go home. The TC Electronic Impact Twin's 24-bit/192kHz HD convertors let you select your conversion rate - all the way from 44.1kHz to the high-definition 192kHz - for the ultimate in pristine audio capture and maintaining the essential transients of your sound.

For years, TC Electronics has been an innovator in the world of signal enhancement, and Impact Twin includes essential recording channel tools that go even further to optimize your sound with onboard EQ, compressor and de-esser that quickly, simply, and invisibly tame and enhance those signals - no matter what you're recording.
