Heritage Audio 73 DI One
Best professional sound for discerning audio engineers.
The Heritage Audio 73 DI One is an active direct box designed to convert high-impedance, unbalanced instrument signals into low-impedance, balanced signals, making them suitable for long cable runs without signal degradation. It features a single high-impedance I/O and JFET transistor for Class A sound. The 73 DI One accommodates both active and passive instruments and includes a -15dB pad for hot signals, a ground lift to eliminate noise, and a Thru output to split your signal to additional gear like an amplifier or monitor. Its sturdy, road-ready enclosure ensures long-term performance in any live or studio environment.

Know before you buy
No, it does not. It is powered entirely by 48V phantom power provided by your audio interface or mixing console.
Yes, the circuit is designed to handle both. It provides the necessary impedance matching to ensure your signal stays clean and full-bodied regardless of your instrument's electronics.
The Thru output allows you to send your instrument signal simultaneously to the DI and an external amplifier or monitor. This is ideal for recording a clean signal while monitoring through your stage rig.
You should use the pad if you are plugging in an instrument with a very high output level, such as an active bass or a synth, that is causing the input of your interface to clip or distort.
Yes, the built-in ground lift switch is specifically designed to eliminate ground loops, which are the most common cause of unwanted hum or buzz in live and studio setups.
