The Radial JDI is the industry-standard passive direct box, built around a premium Jensen JT-DB-EPC transformer. It handles extreme signal levels without distortion, eliminates hum and buzz from ground loops, and delivers the natural sound of your instrument with virtually zero phase deviation. It's a go-to for high-output bass, acoustic guitar and keyboards, on stage and in the studio.
