Pure Sound of the Instrument
The Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. At the heart, the Radial JDI employs the world-class Jensen JT-DB-EPC audio transformer delivering a smooth, warm-sounding Bessel curve, reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artifact. By its no-power passive design, the Radial JDI performs both high-to-low impedance conversion and signal-to-balance over a magnetic bridge that passes the signal while rejecting stray DC voltage. This makes the JDI particularly adept at eliminating hum and buzz caused by ground loops.
The Radial JDI is a phase-coherent, passive direct box employing a nickel laminated Jensen® audio transformer with virtually zero phase distortion, huge dynamics handling, and ruler flat response from 10Hz to 40kHz. The Radial JDI is quite simply the world’s finest passive direct box. With its heavy-duty steel shell and internal I-beam construction, the JDI is designed to work dependably for years in even the harshest of touring environments. Ideal for keyboards, bass, and acoustic instruments of all kinds, the JDI Duplex, and JD6 are also available for stereo and multi-channel applications.
