Heritage Audio is proud to introduce the 73 DI ONE, custom-made transformer-equipped 73-Infused active single channel D.I. box for exceptional professional studio recording, as well as live use.

• Single channel active D.I. Box infused with the emotion and vivacity of a vintage 73 style preamp
• Rich, dynamic direct sound that fully captures the harmonic complexity of any instrument
• Transformer coupled class A output stage and legendary 3-transistor topology
• Sparking high end, a solid bottom end and that low midrange saturation the 73 is famous for

A DESIGN THAT HAS BEEN 15 YEARS IN THE MAKING AND MORE THAN 50 YEARS OF HERITAGE

It’s no secret that we are lovers of the 73 topology since the very beginning of Heritage Audio, especially the 3055-driven transformer coupled Class A output stage which is the trademark of that sound. After years of consideration, we’ve managed to adopt the legendary 3-transistor topology circuit to serve as the best DI you could ever get, at any price range.

BRING OUT THE TRUE TONE OF ALL YOUR INSTRUMENTS

Usually, active DI boxes work best with passive circuitry instruments like guitars and basses but thanks to the 73 DI’s high input headroom, it can also be used wonderfully on keyboards, synths, drum machines and samplers when plugging them directly into a PA or recording system is required. Passive basses such as P-Bass and Jazz Bass suddenly acquire a new life, with a sparking high end, a solid bottom end and that low midrange saturation the 73 is famous for. Instruments like the Fender Rhodes produce their full body and bell-like tone like never heard before. Saturation makes Wurlitzer EPs growl like they’re being amped without the hassle. The list goes on and on.

AND ENHANCE YOUR SIGNAL WITH JUST THE RIGHT TOUCH OF VINTAGE WARMTH AND VIBE

This meticulously engineered design is what gives the 73 DI its outstanding performance, delivering a rich, dynamic direct sound that fully captures the harmonic complexity of any instrument and even pre-recorded tracks.

An attractive yet protective extruded aluminium case makes the 73 DI virtually indestructible and totally roadworthy, with all connections recessed for idiot-proof operation. Available in single and dual channel configurations with a pending 8-channel version.
