Product Description

Introduced in late 2011, the 1073/500 from Heritage Audio 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. This updated Anniversary Edition includes an output level control.

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.
