The i73 PRO EDGE 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 EDGE 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.
The i73 PRO Edge also features two line inputs, two stereo monitor outputs, and two high-performance headphone amplifiers, making it the ideal choice for any recording musician or music producer as the core of their studio. The i73 PRO Edge also supports ADAT IN/OUT, allowing for expansion of up to eight channels of input and output.
