General

The Heritage Audio i73® PRO EDGE USB-C audio interface provides a 12-in/16-out setup complete with a pair of integrated Class-A transformer-coupled 73-style preamps, setting musicians, producers and audio engineers up with that much-loved, all-analogue workflow combined with advanced tech.

Create Studio-Quality Recordings Without Compromises

With three input options - including a mic input backed up by a microphone preamp with up to 70dB gain, clean LINE inputs, and a dynamic JFET DI port for your electric guitar or bass - the i73® PRO EDGE routes any input signal to your DAW in studio-grade quality. In addition, you're kitted out with two additional line inputs, two stereo monitor outputs and two state-of-the-art headphone amps.

Back to the Golden Age

Loaded with a collection of DSP-driven effects modelled after Heritage Audio's own outboard gear and vintage units, the i73® PRO EDGE is the perfect audio interface for recordings with that golden age sound. What's more, native recall functionality makes polishing off tracks - both edited and untouched tracks - using a DAW as seamless as can be.

Wrote the following about Heritage Audio i73 Pro Edge USB-C Audio Interface

This is by far the best interface in the market!! 1073 preamps, DSP plugins with zero latency, and free native plugins that cost more than the interface itself when bought separate. I dint know how Heritage is able to do this but it is amazing!!

Heritage Audio gets properly generous by giving anyone who already has a Heritage Audio i73 Pro audio interface or the hardware version of the Successor a free copy of the Successor plugin.
