Built with Radial’s legendary attention to durability and audio integrity, the ProDI delivers dependable performance and excellent sound quality at a price point that makes it a staple for working engineers, live sound professionals, and touring musicians alike. The Radial ProDI is a passive direct box designed to handle a wide range of high-impedance instruments including electric bass, acoustic guitar, keyboards, and electronic instruments.

A recessed ground lift switch helps eliminate hum and buzz caused by ground loops, while the rugged 14-gauge steel chassis protects the internal components from the rigors of stage and studio use.
