Dual-channel flexibility
Simultaneously connect and convert two instruments with transparent, harmonically rich sound, perfect for stereo sources like keyboards and synths.
KEY FEATURES
The Heritage Audio 73 DI 2 is a dual-channel active DI box that delivers the same premium circuit design as the 73 DI ONE, now in stereo or multi-instrument configurations.
Dual-Channel Flexibility
Each channel features a JFET input stage, Class A 73 topology, and a custom low-impedance transformer. This ensures transparent, harmonically rich conversion of two instruments simultaneously, making it an ideal solution for stereo sources such as keyboards, synths, or paired instruments.
Professional Build and Performance
The 73 DI 2 matches the robust construction of the single-channel model, with a 14-gauge steel housing, recessed connections, and MIL-spec PCBs. Each channel includes a 15dB pad and ground lift switch, while gold-plated jacks and XLR outputs maintain uncompromised signal quality. A red LED power indicator confirms phantom operation, ensuring confidence during demanding sessions or performances.
