When You Need Absolute Purity in Your DI
Radial JDI is a passive direct box designed to handle extreme signal levels without distortion. At the heart of the Radial JDI is a premium Jensen JT-DB EPC audio transformer, delivering smooth, warm Bessel curves reminiscent of the finest vintage gear. With ruler-flat and virtually zero phase deviation from 10Hz to 40kHz, JDI delivers the natural, pure sound of instruments without artifacts. With its passive, powerless design, the Radial JDI performs both high impedance to low impedance conversion and signal equalization via a magnetic bridge that passes signals while suppressing stray DC voltages. This makes the JDI particularly good at eliminating hums and hums caused by ground loops.
