Radial JDI Passive DI for acoustic guitar, bass and keyboards - Industry standard
World's Finest DI
The Radial JDI is a high performance passive direct box designed for professional studio recording and live concert touring applications, it also comes with a premium Jensen transformer for exceptional audio performance.
The Radial JDI is a phase coherent, passive direct box that employs a nickel laminated Jensen® audio transformer with virtually zero phase distortion, ruler flat response from 10Hz to 40kHz and huge dynamics handling. The Radial JDI is created as a quite simply the world’s finest passive direct box. The JDI, with its build as a heavy-duty steel shell and internal I-beam construction, is designed to work dependably for years in even the most stressful of touring environments. The JDI Duplex and JD6, is best use for bass, keyboards and acoustic instruments of all kinds are also available for multi-channel and stereo applications.
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 balancing over a magnetic bridge that passes signal while rejecting stray DC voltage. This makes the JDI particularly adept at eliminating hum and buzz caused by ground loops.
