Description
The Heritage Audio 73 DI One is based on Heritage Audio’s favored ‘70s-style audio circuitry, It delivers superb performance in any live or studio environment. This active direct box features a single high-impedance I/O and a J109 JFET transistor to push top-shelf, Class A sound to your outboard gear.
The 73 DI One is able to accommodate both active and passive instruments, from electric guitars and basses with passive pickups to keyboards, drum machines, and much more. You also receive a -15dB pad to handle extra hot incoming signals, ground lift, and a Thru output to split your signal to additional gear such as a monitor or amp. Enclosed in a sturdy, road-ready frame, the 73 DI One is primed to become a favorite DI in your pro audio toolbox.

Active DI (e.g., Heritage 73 DI): These feature active electronic circuitry to adapt the impedance. They require phantom power, offer better high-frequency response, greater transparency, and capture weak signals more effectively. They are ideal for passive instruments such as guitars and passive basses.
Passive DI (e.g., Heritage P DI): These use an internal transformer to adapt the impedance and balance the signal. They provide excellent electrical isolation to prevent noise or ground loops, deliver a warm and natural tone, do not require phantom power, handle strong signals without distortion, and are ideal for active instruments such as active basses, keyboards, and synthesizers.
