Heritage Audio i73 Pro Edge is a 2-channel USB-C audio interface designed specifically for guitarists and producers. It features 2 x Class A 73-style mic preamps, 2 x JFET Hi-Z DI inputs, 2 x TRS line inputs, 2 x TRS monitor outputs, 2 x TRS line outputs, 2 x headphone outputs, MIDI I/O, ADAT expansion, and a powerful built-in DSP mixer with effects.
Inspired by the legendary British 73 console module, the i73 Pro Edge uses fully transformer-balanced Class A circuitry to deliver a rich analog tone. With up to 70 dB of gain, it easily handles any microphone, including low-output ribbon mics. The JFET DI inputs on the front are tailored for guitars, basses, and piezo pickups, while the dual headphone outputs allow independent monitoring. Rear panel connections include combo XLR-1/4" inputs, line outputs, ADAT I/O, and MIDI.
The onboard DSP mixer provides ultra-low-latency monitoring with custom cue mixes for monitors and headphones. It allows simultaneous recording of both wet and dry signals directly into your DAW and includes loopback functionality. Included DSP-powered plugins model Heritage Audio's outboard gear, offering studio-grade reverb, EQ, compression, and more — all running inside the interface to save your computer’s CPU resources.
