The i73 PRO 2 is an audio interface that allows musicians, producers, and audio engineers to easily experience the warm, musical analog sound that has been inspiring music production since the early 1970s. Featuring Heritage Audio's legendary '73-style preamps (Class A transformer-balanced), it allows direct recording to your computer without compromising their iconic sound character and musical texture.
Like other Heritage Audio '73-style preamps, the i73 PRO 2 features three inputs. This allows you to route any signal to your DAW with uncompromising studio quality, optimally tailored to your source—whether it's a vocal input to a microphone preamp with up to 70dB of gain, an electric guitar/bass to a responsive JFET DI, or a clean line input.
