Heritage Audio announces the new 73 DI Series

Heritage Audio releases the 73 DI ONE and 73 DI 2 as parte of its new 73 DI Series for instantly enhancing your signals both in the studio and on stage.

Heritage Audio® is proud to announce the availability of its new 73 DI Series: the 73 DI ONE (single channel) and 73 DI 2 (dual channel), custom-made transformer-equipped 73-Infused active D.I. boxes for exceptional professional studio recording, as well as live use.

It’s no secret that Heritage Audio loves the 73 topology since the very beginning of their 15 year history, especially the 3055-driven transformer coupled Class A output stage which is the trademark of that sound. After years of consideration, the adaptation of the legendary 3-transistor topology circuit is now a reality to serve as the best DI you could ever get, at any price range.

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

This wasn’t an easy task, as a very high input impedance was needed and phantom power was a must. The first transistor in the 73 stage was substituted by a J109 JFET, yielding a 2.2 megohm input impedance instead of the 47 Kohms in the original circuit. This transistor is the same one that is used (and loved) in the tens of thousands of the preamp DIs that Heritage Audio has included in all of its products over the last decade and a half turning it into an industry standard.

A clever design on the power supply section allows it to keep the metal can 2n3055 output transistor that directly drives the custom-developed silicon steel grain-oriented output transformer, which is a phantom power friendly version of the venerable LO1166, custom built to enhance the natural performance of your instrument in the same, unique way, that a vintage 73 preamp will enhance a mic signal. The results need to be heard to be believed.

BRING OUT THE TRUE TONE OF ALL YOUR INSTRUMENTS AND ENHANCE YOUR SIGNAL WITH JUST THE RIGHT TOUCH OF VINTAGE WAMTH AND VIBE

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 Precision 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 Electric Pianos growl like they’re being amped without the hassle. The list goes on and on.

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.
