Heritage Audio
P DI
Best professional direct injection for pristine instrument capture.
The Heritage Audio P DI One is a passive direct box designed to convert your instrument's high-impedance, unbalanced signal into a low-impedance, balanced signal. This ensures a clean, noise-free signal over long cable runs to a mixer or audio interface. It features a J109 JFET transistor for Class A sound, a -15dB pad for hot signals, a ground lift switch to eliminate hum, and a "thru" output for connecting to an amplifier or monitor. Its sturdy, road-ready enclosure makes it suitable for both live performance and studio recording.
