Description

The Radial HDI is a single-channel active direct box designed for studio work where tonal accuracy matters. Rather than coloring your signal in unpredictable ways, it’s built to preserve the natural character of your instrument while adding a touch of transformer saturation that fills out the sound with musical warmth.

1-channel active DI design for instrument-level sources
Transformer saturation for added harmonic warmth
Line-level output for feeding preamps, interfaces, or mixing consoles
Studio-grade construction suited for tracking sessions and home studios

Whether you’re recording guitar, bass, or other instruments direct, the HDI gives you a reliable signal path that translates well into a mix without extra processing. It’s a straightforward piece of gear for anyone who wants dependable tone capture without fuss — plug in, dial in your level, and get on with recording.

A solid addition to any studio accessories rack, the HDI earns its place by doing one job well: getting your instrument’s signal to tape (or disk) sounding like itself, just a little richer.
