Radial ProDI Passive DI for Acoustic Guitar, Bass & Keyboards

Handle high-output instruments with confidence

The Radial ProDI is a compact passive direct box for acoustic guitar, bass and keyboards, designed for stage and home recording applications. Its custom-wound Radial transformer handles strong instrument signals and dynamic transients, while transformer isolation helps eliminate noisy ground loops.

From the punch of an active bass to the sharp attack of an acoustic preamp or the wide range of a digital keyboard, the ProDI provides a practical direct connection to your sound system. Its passive transformer design helps smooth transients for a warmer tone without adding a powered circuit to your setup.
