About this listing
The Heritage Audio 73DI 2 Dual Active Direct Box is a dual-channel active direct box that brings the harmonic richness of Heritage’s 73 Class A design into your direct instrument paths. Built tough and phantom-powered, it gives you colored, high-headroom tone with low noise for guitars, basses, keyboards, synths, and more.
The Heritage Audio 73 DI 2 is a dual-channel active DI box that embeds the sonic signature and harmonic richness of Heritage’s 73 topology into direct instrument routing. Each channel uses a discrete Class A JFET front end driving a custom low-impedance, transformer-coupled output (the “73-DI” transformer) to produce a dynamic, colored direct sound while maintaining strong signal integrity and low noise. The unit is built in a rugged extruded aluminum frame with recessed connectors and 14-gauge steel panels to minimize mechanical stress and withstand road use. Thanks to its high input headroom, the 73 DI 2 not only excels with passive instruments like electric guitars and basses but is also well suited for keyboards, synths, drum machines, and other line-level sources without coloration loss. It aims to combine the “vintage warmth and vibe” of the 73 sound with the convenience and noise/immunity advantages of a professional direct box topology. The 73DI 2 is the two channel version of the .
