Heritage Audio i73 Pro One is a USB-C audio interface designed for guitarists, featuring 1 Class A 73-style mic preamp, JFET Hi-Z DI input, dedicated line input, DSP-powered mixer with ultra-low latency, onboard vintage-style effects, and MIDI I/O in a rugged and compact desktop design.
Inspired by the legendary British 73 console module, the i73 Pro One delivers transformer-balanced analog circuitry with 70 dB of gain, capturing classic studio character for any microphone, including passive ribbon mics. The front-panel Hi-Z DI input with JFET topology is perfect for electric guitars, basses, and piezo pickups. Rear panel connections include balanced line input, dual TRS monitor outputs, MIDI I/O, and stereo headphone output.
The onboard DSP handles real-time effect processing with near-zero latency, allowing you to craft mixes using Heritage Audio’s plugin suite directly from the interface. The built-in Heritage Audio MIXER software provides flexible monitoring and routing, loopback, cue mixing, and simultaneous wet/dry recording to your DAW. With classic European-style knobs, LED VU meter, and dedicated controls for mono, mute, dim, and headphone/monitor levels, i73 Pro One offers a tactile analog feel with modern DAW integration.
