Description
The Heritage Audio 73 DI 2 is based on Heritage Audio’s favourite 70s-style audio circuits, and it offers exceptional performance in any live or studio environment. This active direct box features two high-impedance outputs and a JFET J109 transistor to send top-quality, Class A sound to your external equipment.
The 73 DI 2 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 2 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.
