General

The Heritage Audio i73® PRO 2 USB-C audio interface provides a 2-In/4-Out setup complete with a pair of integrated Class-A transformer-coupled 73-style preamps. In essence, this is a fully analogue take on the 'Golden Age' of studio recording and, in the name of modern convenience, places it all directly on your desktop and within immediate reach. The i73® PRO 2 has been fine-tuned and honed to treat musicians, producers and audio engineers to some of that seventies-era magic.

Consistent Studio-Grade Sound

At the heart of the Heritage Audio i73® PRO 2 interface lies the same Class-A transformer-balanced switching as Heritage Audio's classic 73-style preamps, feeding your computer and software with the same unmistakable, old-school vibe. Whether you're recording vocals with the help of the maximum 70 decibels of gain via the built-in preamp; capturing the dynamic nuances of an electric guitar or bass via the JFET DI; or taking full advantage of the crystal-clear performance of the line inputs, this audio interface coats everything in pure, high-end studio quality.

DSP-Driven Studio-Quality Effects

Designed to bring the focus all the way back to the music and the musician, the i73® PRO 2 comes complete with all of the tools needed to kit out the home studio, straight out of the box. This interface includes a growing collection of DSP-driven recording effects, each modelled on Heritage Audio's own external hardware and vintage collection, giving you the power to effortlessly enrich, colour and polish your projects in seamless style. And, with the 'native' recall function, laying down tracks in your DAW, whether they've been edited or not, has never been so efficient.
