The Heritage Audio "73" Sound: Console Spirit in a USB-C Interface

With the i73 PRO One, Heritage Audio translates its "golden age" philosophy into a compact format: a true entry into the aesthetic of 73-style preamps, where Class A and the transformer provide definition, musical attack, and a sense of depth right from the source. Designed as a portable studio interface, it aims for a direct workflow: a good microphone, a good take, and a coherent chain without distractions.

An Interface Designed to Record Quickly, Well, Anywhere

The i73 PRO One targets singers, podcasters, guitarists/bassists, and producers who want a "mix-ready" recording right at the input, without relying on external racks. The three input options (MIC, JFET DI, LINE) make adapting to each source easy, while low-latency monitoring allows comfortable recording even during busy sessions.

Monitoring, DSP, and Routing: A Modern Workflow Without Losing the Analog Feel

Built-in MIXER: Listen Exactly to What You Need

The integrated monitoring console is designed to maintain clear and responsive listening: speakers and headphones have independent mixes, configurable within the MIXER. Convenient for adjusting a vocalist's foldback without affecting the main mix, or creating a dedicated headphone balance during tracking.

Real-Time Processing and DRY/WET Recording

The internal DSP allows real-time processing in the MIXER with tools modeled after Heritage Audio's external hardware collection. For maximum flexibility, you can simultaneously record DRY and WET signals to your digital audio workstation, and even integrate third-party native plugins via the MIXER's auxiliary channels according to your workflow.

Quick Session Control

The Mono, Mute, and DIM functions, as well as the pad and phase inversion, speed up takes and adjustments without breaking the creative flow.
