Radial Engineering R800 1038 Passive Reamping DI Box

The Radial Reamp HP is a passive reamping device that takes a recorded line-level signal from your DAW or audio interface and converts it to instrument level, allowing you to run previously tracked parts through amplifiers, stompboxes, and other outboard gear. This opens up significant creative flexibility in the mixing stage—you can experiment with different amp tones, dial in effects, or completely reshape a part long after the original performance was captured, all without re-tracking.

At the heart of the unit is a custom isolation transformer that handles impedance conversion while breaking the electrical ground between your recording interface and the amplifier. This eliminates the ground-loop hum that commonly plagues reamping setups. A dedicated ground lift switch provides additional control if noise issues arise. The inclusion of both 1/4-inch and 3.5mm inputs means you can feed signal from a professional interface or directly from a laptop or phone headphone output. Because it is entirely passive, there are no batteries to replace or power supplies to manage—just patch it in and go.
