The i73® PRO EDGE aims to provide musicians, producers and audio engineers with an easy path to that cherished analog experience that has inspired music creation since the early 70’s. The i73® PRO Edge incorporates the same Class A transformer-balanced circuitry as Heritage Audio’s classic 73 style preamps, providing the end user with the ability to track with all that classic mojo and vibe but, for the first time, straight from the i73® PRO Edge to a computer.

As with all of Heritage Audio’s 73 style preamps, there are three options for input, so whether the end user wants to run vocals through the MIC preamp with up to 70dBs of gain, an electric guitar/bass through the fast, dynamic JFET DI or the clean LINE inputs, the i73® PRO Edge allows the user to route whatever the signal may be on to a DAW with true studio quality.
