Introduced in late 2011, the Heritage Audio 1073/500 set the standard for full 1073s in 500 Series format. With its impressive 3 slot wide chassis, it is essentially a reformatted 80 Series HA1073, employing the same cards and components in the same modular construction technique.

Completely hand-wired and built like a tank, the HA1073/500 will bring the same quality and prestige to your studio as its 80 Series brother. As of 2013, it includes an output level control.
